Hi Rob and Jay,

Thanks for the reports. Nice to see that the path to Rob can be crossed as well. But we are quite close to the limit.

Jay, very nice copy. And yes, last nights message should have decoded easily, even if the SNR would have been 10 dB lower!

The forecast looks good for tonite. Do you like to try a 50 character message with me? Does your PC have enough RAM for 8K21A? With 8 GB it should work.

f = 137.540 kHz
Start time: 13.DEC.2018  00:30:00.3 UTC (6 hourly repeats)
Symbol period: 1 s
Characters: 50
CRC bits: 10
Coding 8K21A
Antenna current: 4 A
Duration: 44:00 [mm:ss]


73, Stefan

Last night's copy ... late start as usual:
 
0030 Rank 0 Eb/N0 7.9 dB CUAGN
 
0130 no decode (QRM from local transmission)
 
0230 Rank 0 Eb/N0 13.8 dB CUAGN
 
0330 Rank 0 Eb/N0 14.3 dB CUAGN
 
 
 
With these results I'm surprised there was no copy of the previous night's 16K21A transmissions.
