Definitely - and I maintain any coherent mode will win out over non coherent ones where the path will support it. And LF will support coherency, especially at 10Hz rates. Wolf has rather been forgott
Andy As interesting as WOLFs ability to dig out the weakest of signals, is it's unrivaled immunity to static. John, W1TAG and I have taken to testing 'digital' modes in both winter and summer ... as
...so Andy, would you suggest it may be useful even on VLF, where the phase is rather stable over a longer time? 73, Stefan Am 28.01.2012 20:18, schrieb Andy Talbot: I've been thinking about the math

Dear Andy, LF Group, So by continuously looking at repeated message, the effective bandwidth will get lower by the average of the number of times it has been repeated. Two repeats 3dB or half BW, 4 r
Hi Jim .. If it "had" to reacquire the PN sequence every frame, there could be no coherent addition. Since the data transmissions are contiguous, I assume it will be continuously locked to the runnin

Hello Andy and group, is done. Although Opera isn't documented, it is quite obvious how the decoding must work to acheive the performance it does, and is no doubt very similar to that in WSPR/JTxx wh

Graham, There is no single s/n figure or specified BW in which to measure it. WOLF works by building copy up over a period of time, and assuming good frequency/phase stability, a half hour or more is
