When performing an auto scan of available stations, the app spits out a nice list of those stations, some with IDs. Unfortunately there’s no default way to convert this to text, but I found an OCR text grabber which did 95% of the work, and then I just monkeyed with a spreadsheet to sort out any oddities, and this is what I ended up with following an FM bandscan on 21/03/2020 at 1425 UTC:

Where a station ID was decoded via RDS, it is listed. Where I’ve made it bold and italic, it is believed to be a pirate station. The rest are legit local/national FM broadcasts.
Where there’s no station ID listed, it’s simply because the FM radio app didn’t pick one up in time – some of those blank stations may a) be legit and b) indeed have an RDS stream, it just didn’t get logged in time. Either way, it could be pirate or legit.
A couple of them are stations that I knew had RDS data, and what’s nice about the Motorola FM Radio app is that if you tune to that station and it didn’t already have data, it adds it where possible, and this gets added to the overall list as above. This means that after a full scan, if there are gaps in the data, one can simply tune to the first station with a blank name, and let it play for a few seconds until RDS data comes down – if it has any. – and then use the skip button to move to the next logged station.
It only takes a few seconds for RDS data to appear, or for it to become clear that none is being broadcast. Weak signals inevitably mean the RDS data is corrupted, possibly beyond legibility.
Oona Räisänen could probably explain in quite simple terms exactly how RDS data is decoded and why some stations seem to display RDS data quicker than others. In fact, it’s Oona’s RDS projects that make me think that if I really set my mind to it, I’m probably like 90% of the way to creating a pocket-size, Raspberry Pi Zero-based RDS decoder.
What I think I want is a little device that I can pull out, attach to an antenna, run a quick 1-2 minute bandscan, and in that time, the Pi scans the whole FM band, logging as much RDS data as it can grab, plotting it neatly on a little spreadsheet, which I can then inspect later on.
Better yet might be adding a simple 2-line display (much like a portable radio) where I can see each station being scanned. There are other possible modifications that could be made that would effectively turn it into a usable radio, but I’m thinking more along the lines of a simple logging device.
On the other hand, it might make more sense to do some sort of spectrum grab using SDR where the whole FM band is captured for a few minutes, for later analysis in software. This whole concept blows my tiny mind – and, really, seems less fun than doing actual listening to live broadcasts – though I can absolutely see the appeal and the benefits for logging weak/rare stations when DXing.
Well this was the week that things really changed, for me and those around me. It’s been interesting keeping abreast of how the spread of the virus and the reactions by different countries has rolled onward, in waves. Interesting and kind of horrifying, when you spend more than half a minute considering what it all means.
It has, in many ways, been good that the upheaval has kept us all so busy. Heaven forbid what will happen when we are all set up with our new routines and we stop for a second to get bogged down in the sheer existential woe of it all – and that’s before even considering the actual health crisis worsening any further, which each day it threatens to on a hitherto-unseen scale.
We have found ourselves unexpectedly buoyed by taping occasional news updates from Chinese state broadcasters in which they describe the recovery process. Life, while not returning to normal, per se, is returning to something approaching it. Or at least a healthy, post-virus world.
At work I have been extremely busy helping as far as I can to get the office set up for home working. A few months ago, working from home on the scale that we soon will be would have been completely unthinkable. But, as with so much of this escalating crisis, unthinkable things are now having to be thunk, and it’s funny what you can achieve when you have to.
In fact, the extent to which we’ve established a working-from-home policy means that it’s only really a few little issues and niggles we’ve found, rather than any flat-out business critical failure points.
We’re lucky in that a lot of what we do isn’t business critical. And where it is, the timelines and deadlines are those we set for ourselves and we are fortunate enough not to be beholden to many authorities or external/market forces. We have a job to do, and we do it however we can. This will not change, but the methods and timescales may.
Meanwhile, anything that isn’t related to work, or keeping ourselves constantly updated on news has, by necessity, been for the purposes of distraction, amusement or entertainment. The rest of this week’s note is simply some of that stuff that has kept me from losing my mind the past few days.
We had the first day of spring, and the weather this week has been cool but increasingly wonderful and bright. There is blossom everywhere, and the spring weather looks set to continue. This does mean that people who ought to be self-isolating are popping out more than they might if it had been tipping down all week, and I am concerned about that. But at the same time, the sight of spring springing is a huge boost.
As well as a brief trip to a nearby park (where I saw the woodpecker above), I also popped to Hampstead Heath on Saturday to get some fresh air. Unfortunately, so did a lot of other people, and I really should have known better. I was able to keep my distance from most people, and I found myself a secluded perch where I spent a happy hour or so playing with radios, and eating cold pizza.
On FM, my elevated position near one of London’s highest points meant stations came booming in loud and clear, and I found a good number of pirate stations giving shout-outs to the shut-ins.
I found that the signal on my little POP Nano radio was decent, but both my Tecsun PL-380 and my Motorola G7 Power logged 58 stations each on the FM band, with the Moto serving doubly useful as not only does it have an RDS decoder built-in, but it also neatly displays all logged stations in one big list, acting as a very useful results page for active stations complete with station IDs, where available.
I’ve written before about the pretty excellent FM radio software on an older Moto G device, and it’s just as good on my current G7 Power. It serves as an effective stopgap between idly tuning around with a normal radio and setting up some sort of portable SDR that will automatically log station IDs in a neat spreadsheet for me.
(A rainy day project I daydream of is a Raspberry Pi Zero-powered unit that I can just switch on, run an autoscan, and log all active stations in a spreadsheet. Might have a little screen and possibly audio out.)
The subsequent list generated by the Moto is displayed as you can see to the right: it’s a neat list of station IDs and frequencies and I only wish I could quickly and easily export this data into a spreadsheet. I suspect there’s an OCR capture that could do a half decent job. But even in its present form, the FM radio software gives me a decent overview of what’s around in a given session.
One surprise, beyond the ever-present London pirates, was decent reception of a station apparently broadcasting to Greenwich on 96.5fm. A later dig around uncovered this as Maritime Radio, with the always-helpful mb21 giving more information about where this station broadcasts from. Not a bad catch at a distance of approximately 20km.
It’s hard to tell where the pirate stations themselves broadcast from – obviously – so it’s never easy to known whether you’re getting fabulous reception across a vast distance, or merely being blasted from the nearest rooftop. I suspect it’s usually the latter, though there is usually a good range of signals when tuning in from a high point in north west London, with some sounding stronger and others weaker.
The variability in the tech used by each pirate could give rise to this, of course, but it all makes it feel as though you’re picking up signals from all over London.
On DAB, my position near London’s highest point meant great reception of a huge range of stations. The POP Nano picked up 148 stations without issue, and I noted down that I was getting reception of the following multiplexes on top of those I’d expect to get in London: Kent, Herts Beds Bucks, Surrey NSussex, and Essex. On the one hand, these extra muxes simply bring in local stations or local variants of commercial stations. But it’s still pretty cool to pick these all up along with the ones which are meant to cover my area.
Of note, the Kent multiplex coverage map [PDF] does show parts of Hampstead as able to pick up occasional offshoots of the signal over high ground:
So it’s perhaps not that unexpected, but still vaguely interesting to me.
I also had a scan around on shortwave and aside from the usual national broadcasters who have mastered dominating the waves, I was pleased to pick up two pirate(?) stations on 5780kHz and 6205kHz – possibly Laser Hot Hits and Euro Radio. (This was at approximately 1445 UTC on Saturday 21 March.)
Nothing else really of any note on the radio, although I did spot this new addition to the London Trial multiplex – Health Info Radio, which launched a week ago on various other local muxes, and whose sole purpose is to play a looped recording of coronavirus-related public information.
On the YouTube front, beyond the usual tech videos I tend to gorge myself on, the algorithms threw me a wonderful bone in a series of aviation videos by a chap named Matt Guthmiller. I’m not sure what YouTube thought it was doing, but I was absolutely enthralled by this four-part series on flying a 1930s DC-3 from the US to Duxford.
Spoiler alert: it’s not quite as simple as hopping across the Atlantic. In fact, it involves hopping to Canada, Greenland, Iceland, and Scotland, before hopping down to Duxford.
At times, the serenity and majesty of early to mid 20th century flight is intoxicating, and at others you are hit with the nauseating concept of hurtling through the air in nothing much more than a 1930s bus with temperamental moving parts and a hell of a lot to understand about how to get it airborne and keep it there.
The four parts are available in this playlist, or just watch the first one below:
Pro-tip: use the ‘Watch later’ button to save these kinds of YouTube clips to a… Watch later playlist.
And finally, I’ve recently seen a few good links to online collections of stuff and wanted to share some and add one of my own.
And finally, the National Trust’s ‘Collections’ image database is staggering in its scale – they have photographed countless objects held within their collections at the various properties they look after. You could find yourself lost for weeks on this website, whether searching across the entire collection by keyword, exploring the contents of one particular property, or paging through the works of one artist.
By the collection’s very nature, this is not a greatest hits, but a snapshot of all that is contained within it: from sketches on the backs of letters, to glorious watercoloured ink sketches like that shown below, of the Great Wall at Hampstead Garden Suburb.
Desert Oracle – first the little magazine and now (only?) the radio show and podcast – isn’t something I listen to every time. But occasionally it’ll catch me in a receptive mood and I’ll think an episode was just a downright classic. The recent episode number 79 – These Enchanted Lands – was one such smash. Pretty much just a solid monologue of fascinating and spooky goings-on which is when Desert Oracle is at its best.
Repeats of I’m Sorry I’ll Read That Again are just what I need some mornings before work, leaving me chuckling away to things that were funny in the 1960s, and the silly songs that still tickle me today. Hearing John Cleese do a sketch where he complains about his wife spending all his money was particularly amusing in how prophetic it was.
It’s nice to be reminded of how excellent and eclectic Radiophrenia was – it was a block of broadcasts of experimental radio and sound art last May, but Resonance Extra continues to replay it at various times, and it’s always a delight to hear a few random snippets of it. I’m not sure if it will be running again this year / in future.
I was also reminded recently that it’s nearly time for Audiograft in Oxford. I went to the event in 2018 (mentioned in this weeknote) and enjoyed some of what I saw, and generally found it all quite interesting and inspiring.
Looking at the programme this year, I see less that grabs my attention, but I can’t decide if that’s because of the way so many of these installation descriptions and synopses are written. Sometimes I just kind of want to know what it is the installation will look or sound like, and sometimes there just aren’t enough words to properly explain that.
Something something dancing about architecture.
Obviously I should just go with an open mind and support a cool festival. I might find something completely unexpected. Will look at trains and suchlike.
Some daffs – we’ve been on a daffs kick lately, it seems
Work continues to be just a lot at the moment.
I realise that many people work much harder than I do, but circumstances have conspired recently to mean I am currently either directly or indirectly involved with a large amount of stuff and am being called upon to make suggestions and recommendations on things I don’t feel I have the confidence to answer.
There is an end in sight, but it’s currently quite draining. I did have one nice comment from a colleague which came out of the blue and surprised me, which was nice.
This shift in responsibilities also led to me attending an afternoon session on recent updates in charity law which… well. I suppose some of it was vaguely interesting – particularly the Information Commissioner’s Office (ICO)’s approach to breaches of GDPR and so on. But other elements were at best just not relevant and at worst confusing.
One speaker criticised the Charity Commission on a number of levels before explaining that she felt a fraud case involving approximately £25,000 for a charity with a turnover of c.£10 million probably ought not to be seen as ‘significant’ and so shouldn’t be reported to the Charity Commission as a serious incident.
Which is alarming.
Possibly she just meant what the Charity Commission deemed significant or serious, and she did clarify by saying any incident should be reported, and the Commission can decide whether it’s serious or not.
Sometime last year – I think it was from watching the Glastonbury coverage on the TV – I realised I had a bunch of 7″ singles just sat on shelves which I never play. I saw The Killers performing and remembered I had one of their first singles on vinyl, and quickly wondered how much such an item might fetch, fifteen years on*. And then I wondered what a load of my other records might fetch.
* In fact, it sold for more than £30, which wasn’t a bad start.
About half of the singles I’ve accumulated are things I would consider objects I have collected and feel attached to, whereas the other half I just don’t particularly have a connection to, and I may as well get rid. Some were duplicates of releases I do care about. But overall, they just never get played. I listen to 12″ albums now and again, but singles with one track on each side I just never really listen to.
I set about listing some of these on discogs.com and ever since then I have been selling one or two a month with *touches all the wood* no real issues. I had purchased from Discogs in the past with no issues, so it’s pleasing to find that the other side of the process is just as painless. Discogs also helpfully gives you an indication of the asking price for most releases, based on previous sales.
It’s also been the perfect combination of things for me: I have some niche, weird stuff that I no longer really care about, and Discogs has connected me with buyers who do care about it and would like to pick some of it up. Most are not that valuable. But Discogs has made it easy for me to find a buyer and to transfer it from one home to another where hopefully it might get a bit more love.
It’s nice selling stuff to fans and collectors. In fact, one of my first sales was to someone who hosts an overnight radio show in Estonia, which is just great. They’re exactly who I want buying my old 7″ singles.
I wonder if listing things on ebay might be better for certain items, particularly as, by default, Discogs doesn’t show photos of the item in question, just the metadata associated with it and the grade the seller gives it in their opinion. Ebay would at least allow me to add more photographs and details about my particular copy. But when I remember selling stuff on ebay, it just feels like such an effort. Discogs lets me just upload a bunch of stuff and leave it on sale until someone wants to buy it. Easy peasy.
Not much else to report this week.
I spent a bit of time in the Wayback Machine museum of ye olde interwebs the other day, poring over one particular website that I followed back when I started following websites. It was a personal website slash blog, and the owner seemed to have had it online for only a few years. I have no idea what happened to them after the website went offline, and I often wonder where they are now.
Part of me wants to do some digging and try and find out. Part of me just likes the neat open-and-shut case of it and is happy to leave it as a time capsule I occasionally peer inside. I think I’ll write more about this subject another time when I’ve formulated my thoughts a little better.
This dig into the Wayback Machine also uncovered a version of one of my first websites that I didn’t realise had been mirrored, which was a nice discovery.
I was pleasantly surprised to find I had thought to include a little extra colophonic metadata in the footer, which is something I love to see, and which I must get back into:
Reader, I still occasionally listen to ‘incubus’ and ‘the living end’.
Recent radio and podcast listening: Radio 3’s Saturday Breakfast and Unclassified with Elizabeth Alker; Giles Coren and Esther Walker’s podcast Giles Coren Has No Idea; Late Junction.
I think I’ve set myself an accidentally high bar when it comes to Weeknotes as I seem to be writing a thousand words or more and sometimes there just ain’t enough notes for the week. This week is one of them.
Trying to summarise office-based workmadness is getting beyond me, but I’ve noticed it’s taking up more and more of my mental energy which is in some ways good and in more ways quite bad. I keep having (or needing) little things that provide context and help me to separate work life from life life.
I went to see The Lighthouse this week and it was batshit crazy, and very enjoyable. It’s always so fun to watch a film that seems to have such a good grasp on what it’s trying to achieve, and it feels like it was all hands on deck. There’s a lot of questionable nonsense in there too, but not everything has to make sense. I really enjoyed it.
I seem to have made it this far knowing little to nothing about the director or producers/studio – possibly because some of their other output has been (afaik) horror, which I don’t tend to go for. But I find that I like media that sets itself restrictions and works within them (or, I suppose, watching old stuff that had what we now know of as restrictions but which were, at the time, simply the norm). So I may check out some more in this vein.
I picked up a new camera lens on a recent visit to St Albans – an old SLR 35mm f2.8 thingy from the 70s or 80s I think. I already had an adapter for putting M42 lenses onto my Canon dSLR, and I am happy to report that I’ve been enjoying using this new one.
It is extremely manual, and obviously focus is an issue as, with a modern dSLR, there isn’t a frosted glass focus aid or similar, so you’re just doing it by eye through the viewfinder. Or you can use zone focusing, which I don’t think I really understood before, but which I do now (to a degree), and it has helped me achieve some nice results.
On top of this it’s just a nice object – all-metal, solid construction, etc. It’s nice to have in my collection of lenses.
At the weekend M and I popped down to Hastings – oddly enough a repeat of a trip five years earlier, and somewhere we’ve felt drawn towards on a couple of other occasions since. We had a nice (if rainy and stormy) couple of days down there and I’m intending to write separately about our weekend.
I took my new lens and took some pictures with it.
One draw was the Hastings Parkrun course which is a fast, flat, out-and-back along the sea front. I’ve run that course twice before, so this time went for a third. Being on the front and out-and-back (and in the beginnings of storm Dennis) meant for a particularly fast out and a running-face-first-into-the-wind back. Fortunately what this meant overall was that I broke my PB for a standalone 5k*, which was unexpected and very nice.
* Strava tells me I’ve run a faster 5k before, but in the middle of a 10k run, which figures as that would make it a 5k with a rolling start and finish which you’d expect to be faster.
Anyway, being at the coast is nice and being at the coast in a winter storm is also quite nice (with the usual caveats). We ate good food and as much as we got soaked and windswept, we also found lovely cosy little places to warm up and dry out.
There we are, you see? I only wrote 700 words this week. Let’s see what next week inspires.
I feel like if I try and write these things quickly I might – just might – end up at weeknotes zero (as in, up to date, not going back in time). So, here she is: week three of 2020.
I noticed recently that my listening habits have tipped the balance from being mainly podcasts and some radio to mainly radio and some podcasts. This happens from time to time. I go through phases where I care more about what middle-class white guys have to say about the world of consumer technology, to caring more about music, current affairs and experimental radio and sound art. Thus, lately my ears have been mostly full of the latter.
An average day might look like this (thank me later, RAJAR):
Centreforce is not my usual cup of tea in terms of music. BUT it has the energy and pep of a breakfast show that I can’t help but enjoy at that time of the morning. But what really seals the deal for me are the shout outs. The radio nerd in me wants to call them QSL reports as listeners-in from Kent and Luton and Kilburn and south London chime in, with the deejay reading out the reports a few at a time every few minutes.
Out to Danny! Out to easy Dee, how are you fella? Out to Sam. Out to the 198.* Out to Bob the chippy – large cod and chips for me please mate – ah just kidding, not that kind of chippy are ya?! Out to Razzer. Biggin’ up Sara in Dagenham. Outs to the Cheshunt crew – oi, bring us a bacon butty yeah?
And so on. With deft use of the faders between each announcement for a brief burst of music.
* I believe this is a reference to the last digits of a phone number when used to identify an otherwise unnamed correspondent, rather than, say, Centreforce masquerading as a numbers station.
And it’s brilliant. It makes you feel like you’re on this big map of London and the home counties, where Centreforce, which started life as a pirate station, now broadcasts legitimately on DAB in glorious* 32kbps DAB+.
* listenable, but entirely not glorious. The state of Britain’s approach to DAB broadcasts is a bit of a shitshow, with the majority of stations still being in old-school DAB, and those that are in DAB+ having to squeeze as much juice as possible out of the fact that the more efficient codec allows for lower bitrates. As an example, Belgium broadcasts all its stations via DAB+ almost entirely at 96kbps, whereas most experimental British DAB+ streams seem to top out at 64kbps. ANYWAY.
Sure, the shout outs might be inflated or manipulated somehow but…. I bet they’re not. It just gives a lovely warm interactive edge to listening in, particularly on a breakfast show, as we are all variously on our way to work, on our way home, getting the kids off to school, or rejoicing in the sweet kiss of a day off.
The ‘OS’ show on BBC World Service is a funny one. It’s broadcast live from the middle of the newsroom at Broadcasting House, and sounds like it too. It’s one of the least good-sounding radio shows I listen to at the moment as there is a lot of background noise, and frequent delays when patching in correspondents from around the globe.
But, as with all good radio, this doesn’t get in the way of the content itself being great. It’s a refreshing take on the day’s news – and as with most BBC World Service shows versus BBC Radio 4, it knows it has a global audience, so you get the impression you’re hearing the news that actually matters on a global level rather than a bias towards events nearer to home.
Unnnf. Love it. Click through for how/why, and some other visualisations of similar data.
We also went to see Rose Matafeo performing her Horndog show at the Ambassadors Theatre which was great. She’s so funny and full of energy. I hadn’t actually seen her do full stand-up before, but she is great on Taskmaster and other things we’ve seen her in. Her show was great. The one we went to was a sort of technical rehearsal for a filming the next day, so it’ll be available somehow, soon.
It also meant that through a stroke of extreme luck, I managed to book seats dead centre of the middle of a row in stalls, right behind a space where some seats had been removed to place a camera for the filming the next day.
If only all London theatres had this kind of legroom.
On Saturday I went to a Field Recording workshop in Bethnal Green which was run by the label nonclassical and hosted by sound artist Kate Carr, whose Field Recording Show has recently just finished a run on Resonance FM and which I absolutely loved.
It was a really great session – inclusive, interesting and a great opportunity to understand different takes on the same medium, and to try out new techniques and equipment in an encouraging and helpful environment.
For me, it was cool to try out a pick-up coil mic to record electronic noises which are not normally audible, and it was great to be encouraged to explore the immediate vicinity – a busy high street and a London park – looking for interesting sounds to do… something…with. (More on that in another post to follow.)
It was also an opportunity for me to chat with other like-minded people and find out about their motivations and projects. I struggled a bit with that aspect, but only through my own anxieties and weirdnesses. It was, as I say, a really inclusive, lovely crowd.
They’re running more workshops and I’d highly recommend it to anyone with an interest in field recording, regardless of background or prior knowledge.
And on Sunday we started the day off seeing Princess Mononoke at the Kiln – which was more batshit than I’d remembered, but no less beautiful.
I then decided to go for a longish run. Longish actually turned into 22km or so, which was perhaps a bit overlong given my lack of preparation. But the weather was lovely, I had good snacks and music (Gerling’s In the City came on at a really well-timed moment), and I met some fun animals.
