Good day all, here the results of my decodes. I have used the time offsets indicated by Markus and Paul (thanks !) to start searching the sequence. Signal is very weak here and there is no possibili
Markus Paul and Domenico, Group I have new message 5 characters 512 symbols and hopefully corrected the timing offset a bit. Will start in 1 minute at 2000 utc and on the half hour. Running 50 watts
Are these transmission using 1s or 2s symbols ? Missed the 2000 sessin, but I'll record some of the later ones. Andy On 26 November 2015 at 19:59, <[email protected]> wrote: Markus Paul and Domenico, Gro

Hi Andy and thanks for tip of putting the diode across the gate of the PA MOSFET in your posting a few months ago. I'm using the class E amp at the moment. The XOR can idle with high output so I deco

Paul, The exciter quit sometime during the night. Perhaps around 0400! Nice numbers for 50 watts and poor timing on my end! I know someone who might have a source of GPS PPS to correct this problem.
RR. I see some urgent GUI mods needed At the moment, to record successive sessions, each one has to be started manually (although it does have auto restart at selectable time boundaries). So I have

There is a faint trace visible on the waterfall at the moment 0.122Hz bins, . I guess you're in carrier mode. During the transmission, there were occasional short lines there, corresponding pres

2030 decode was fine, callsign decoded after about 4% - did the graphic dump of the screen pass through the reflector ? 2100 decode not so sucesssful WBPZO which is wrong ? Rank 11069 Es/N0 -14.
Hi Andy and Paul, Happy to hear of your decode, Andy. As for the clock, I actually had to reset the system because the pause time was incorrect. The 2030 one was started by yours truly listening to C
