Hi Graham you may not be aware that the only modes that were available in the early days when the 1st TAs were achieved was QRSS3. Robert Horne, author of Spectrogram saw now use or reason for a slow
Its difficult Stefan because everyone is different, I didnt get much trouble from DCF39 when I got a radio with a decent (Collins) IF filter. In some part of the world its cleaner since the demise of
Hi Alan, What do you estimate, what is the average global background noise level increase in dB due to the rising QRM generators (SMPS, plasma TV, energy saving lamps.....) since these early days? 73
Hi Graham there was a fair amount of skepicism about the possibility in those days :-)) Yes VK is going to be quite difficult from the UK. You have extra problems at the antipodes as signals can arri
One conclusion Peter 'PLX reached on our original 73kHz SlowCW (the proper term we used then, none of this new fangled Q code stuff) was that although the 73kHz path was very bursty with non Gaussian
R Alan, Yes a lot of myths linked to the 'Bright light's' of 136 , but I think the UK/VK full decode is yet to be achieved ? ive seen wiggles and squiggles down under , bit like starting a old vintag
R Alan, Good point on the multi-path to VK , that's one of the un-anticipated advantages of the Op system, as its only 1 carrier , on/off phase distortion is not a problem along with Doppler, the cod
