The GR-81 hasn't seen the light of day since the '60s, thanks, one has moved on to PLL and such niceties. But Havana is pretty much inescapable at least in the East (even with our govern-mental Greenville tax dollars jamming it), and since most of the old broadcasting stalwarts have abandoned the HF bands in a nod to changing times, there's little else extant in the way of readily-audible material on those airwaves, save Havana and the ubiquitous bible thumpers, the only real difference between them being that the USG doesn't jam the bible thumpers. Even though they're in direct violation of their own licenses by targeting domestic audiences.
Moscow was never difficult to hear in its day. Indeed it was noted at the time that the USSR transmitters did a better job reaching across the pond than VOA did with two and three times the power, simply for more efficient radiation -- again, the good old Murkin stick-a-V8-on-a-motorcycle mentality.
And of course I logged it, along with its East European satellites that were just as easily monitored. That's the whole point of DXing --
to see what's out there. You may have preferred in your usual style to stick your head in the sand

but I've been known to endure a broadcast that's not even in a language I have any clue of understanding for hours, just to log that obscure elusive signal. And hearing the USSR propaganda machine gave me a good ear for how propaganda works, which is actually the same reason I read your posts. Fringe listening, you might call it in both cases.
No Virginia, the fact that I'll listen to a time signal station from South Africa doesn't in any way mean I'm doing it because I want to know what time it is. But your predilection for dictating to other people what they "should" or "shouldn't" be listening to is -- shall we say confirming, if not revealing, since we already knew you're a loyal minion of the authoritarian jackboot mindset.
