While you were beaconing last evening I noticed a strange phenomenon on your signal which I can best describe as being similar to the aircraft flutter heard on VHF. During your long bursts of carrier there was a very deep cycle of QSB, fading at least 20 dB at about 2 cycles per second (allright then Hertz). I have heard this on your signal when you have been testing previously, but have never heard such deep or rapid fading on any other 136 KHz signal. Has anyone else noticed this? Anyone have an explanation? 73, Tom G3OLB
