Stefan, ''not over the long and deep QSB of course''. Unless 'of course' the modes was profiled for MF usage , in which case the interleaving is long enough to ride out the qsb , long interleave and

LF Searching for a Narrow Keyboard QSO mode suitable for QRP on 630m. I went back to a program I used several years ago. Currently Testing GMFSK not to be confused with gMFSK which is a Linux program

Sucess. Just a little more signal and this would have been a really good QSO over our path of 127Km conditions are not good tonight, my antenna current is down. Eddie On 11/03/2013 21:53, g3zjo wrote

Hi Stefan I am sure Gary is keeping track of the modes he is testing. All I can say is that RTTY, Amtor and most common MFSK modes are too fast for use by lower power stations of for greater distance

Hi Eddie, LF/MF, I'm a bit confused in the last days by the number of various digimodes which have been tested. Gary started with RTTY which is fun and allows real QSOs on 630m, apart from CW. But if

Its all down to power S .. the bigger the signal (rx end) the faster you can go with the 'very' long qsb , the interleave (FEC) time has to be able to bridge the gap in the signal , so you will alway
