Subject: writelog across isolation transformers
My writelog software now works on any mode RTTY CW SSB including macros.
But I have a problem WITH SSB TX when I add insulation transformers (one on
RX the other on TX ) in the computer audio output ( there is two transformers
1:1 at 600 / 900 ohms in a small box wired in parrallele with only two wires to
the stereo connectors, one wire to the tip, the other to the ground side, and I
respected the primary and secondary polarities ) ...? .
I did'nt connect a secondary line side to a resistor or any other part as
mentionned in articles ((( because it was working like that before, no more
then two weeks ago when I decided to use shielded wires which was'nt before (
was smal lamp cable )
((( --- CORRECTION: In RTTY & CW I have RX & TX + audio --- )))
((( --- But in SSB I have a PTT on the rigblaster box but no audio from PC
eared at RB (spkr) out connector so in ssb mode = no tx... ? --- )))
Is there soemeone that an idea
