But without a single channel roofing filter a 130 dB outband signal make the AD converter overload, despite any sampling rate. Or not? Keep total signal less then overload treshold. You do not (!) n

I transmit this evening on 135.9222 QRSS60 AR AR AR Nice copy here but only when QRM gone. Unfortunely QRM gone sometimes only last night. 73 de RA9MB/Alex http://www.qsl.net/ra9mb

Hi LF, There is about 3 hours of mutual dark path between ZL and RU6, and the distance is some 16,500 km. For listeners west of ZL the only reliable time I can advise that ZM2E will be transmitting i
Hi, LF Nice copy RX9BS last night on 137774. Screenshort attached. Also saw OSO with RU6LA . Besides I have decode RA3YO called RX9BS. It is suprisely I can decode RA3YO audible after using mix-then-
Hi Wolf This is in fact surprising... I tried the same years ago and found my ears were inferior to the eyes ;-) but I will try the same again which my audio playthings (which run under windoze). May
Hi, Dick. It is nice idea! Certanly this should work. Elevated coil is better then coil near the ground, not too much better but better anyway. And a tuning problem gone if one use fig.2. This means
Though somone similar to \omega'=a*\omega + b/\omega with constant a and b. This is NONLINEAR transformation which yelds some distortion of response. 73 de RA9MB/Alex http://www.qsl.net/ra9mb
Dear Jim and group, IMHO this is true for narrow bandpass filters only. If bandpass is not narrow in comparison with central frequency then one can do LPF to BPF transformation also. But it is more c
Such a nonsence... Vector-potencial wave and conventional electromagnetic wave is the absolutely (!!!) the same things... What about detection by a plasma... may be may be (there is nothing detals to
