Jay and Rob,

thank you again for your efforts (and patience) to rece= ive my signal across the pond.
Thanks also to Stefan and Michel for the plots: I think the und= esidered phase jumps problem still not fully resolved here.

So, good job, Jay! My antenna is an inverted &= quot;L" (12m. heigh, 36m. long) fed near the top with about 300W.


All the best

Hi Jay and all LF EbNauters,

Many thanks for your reports and suggestions.
And many thanks Jay for your efforts. Yes, indeed: so I'll try ton= ite with a half of symbol duration, pratically the same parameters used in = my transmissions on 14/15 Nov. 2018:

QRG: 137545 Hz
Coding 8K19A
CRC 16
3 sec./sym.
6 characters
Duration: 28 min.
every 30 minutes, 1st transmission on 2100 UTC, last on 0700 UTC.
<= /div>

Reports are welcome as usual...


All the best
