Another good friend passes away in the form of long-wave broadcast of BBC Radio 4 output, now restricted to frequency-modulated transmission on medium wave; else a Digital Audio Broadcast (DAB); else and altogether more common nowadays, over the internet.
What we do with all technology is to mistake the convenient for the good, however, although that only becomes apparent after the fact.
At the outset of an off-and-on working career in London I shared a flat in a recently gentrified part of Forest Hill in Southeast London. An elderly man occupied the roof-space, which would have been intended for servants when the house was built. I did occasionally visit Mr Newcombe, or 'nuke' as my fellow-flatmates called him, without ever visiting themselves.
As a consequence I inherited a half-bottle of Campari, the sort you bring back from a holiday where it was consumed on the beach but which doesn't quite work on your return back home. And a radio, of the sort with a knob on top to turn it on and after adjust the volume and another to move a linear pointer along the frequency scale in order to tune it to whichever frequency. Between these were a display along which that pointer moved, and buttons for pre-selections besides setting the frequency at whichever broad range of wavelength was required.
I left all of this set to Radio 4, for the singular reason that it could be turned on and the news listened to at six or seven o'clock prior to work or the weekend's activities.
Now this can be done by picking up a phone and if necessary winding things back to the start. But there's no discipline in that, and for centuries Western civilisation ran on a bed-rock of monastic discipline where everything was done to the clock and the routines of work in the fields and workshops were as often as not dictated by church bells.
And it's how we think easier is invariably better, and thus have to invent things like gym classes and parkruns and charity hikes in order to compensate for a life on the sofa watching David Attenborough get out of bed in the morning instead.
The ends of the radio as was done in the 1960s or 1970s were finished in hardwood panels, one of which had come loose and pivoted around the renting fixture at the top end... which only added to the attraction. Life is not perfect, people not perfect, and thus it is that we crave cars and phones that at least appear so.
Radio 4 was known originally as the Home Service, and provided news to the more serious-minded types whilst the Radio 2 had been called the Light and aimed at the plebeian end of the populace who preferred more musical fare. Popular music was only broadcast officially from 1967 on in the UK, with the introduction of Radio 1 to accompany the re-framing of prior output as Radios 2 and 4, with Radio 3 added for classical music that nobody listened to.
All of the underlying science would be analysed in much greater detail when training for a commercial pilot's licence, and I can summarise it here. The military where I learned to fly were granted UHF radios, literally above and beyond the civilian realm of VHF and its medium waves. Navigation beacons like VOR or the VHF Omnirange still in use shared this space, to the extent illegal FM stations might overstep their territory so that listening in to their 'ident' you'd hear a musical playlist instead.
Over at the long-wave range of VHF meantimes, this was used and I think still is by the rapidly disappearing means of navigation called a Non-Directional Beacon, used nowadays if at all solely as a last-resort aid to confirm you're on the right approach course prior to landing. It was based on the fact that a ring-shaped aerial provided the strongest signal when facing toward transmitter, and these hoops can be seen on any number of vintage ships and aircraft.
It also meant that such navigation receivers could be tuned to long-wave broadcast stations like Atlantic on 252 kHz, which relieved the boredom of longer stretches of the North Sea during night-flights hauling freight.
In later years co-pilots would bring a phone and set their playlist to run during the pre-flight preparations on the flight-deck, and having been trained in the military and brought up with the strictures of long-wave radio broadcasts, I'd say 'Please don't do that' and in the end they'd appreciate me saying so, not least for being in one piece.
Later it was more a case of suggesting that with the take-off roll in view it was as good a time as any to stop messaging your mates; although nowadays looking at YouTube I realise that the flight-crew's number one priority is less your safety and more the highest possible number of views. Which, making money being theirs, the airlines are entirely happy with.
