Hi Ric,

>> the bandwidth on your grabber se= ems larger than Domenico's

Well this is not really so. The spe= ctral lobes from your 2 s PSK symbols are only half as wide. The = peak in the zoomed spectrogram section comes mostly from the carrier p= ieces before and after the sequences. Domenico was using longer ones,&= nbsp;resulting in a narrower peak. In addition you are close= r to me and your signal is simply stronger here.

Bes= t 73,
Markus

In my case the BPSK modulation is simply obtained by a CMOS XOR port, in fa= ct the bandwidth on your grabber seems larger than Domenico's EbSynth test = signal. Now I'm putting 200W on antenna.

Warning: it will take about 20 Gbyte RAM to decode 6 chars.

About 5 Gbyte for 6 chars with 8K23A.

8K21A about 1.2 Gbyte is a good choice.
