Hello LF,
many thanks for the reports Markus and Michel and, of course,
compliments to Paul for this masterpiece of software. Last
transmission was sent at 23.30UT and now QRT.
Some details about TX setup:
EbSynth runs on a small PC 2-core Intel 1.83 GHz (saved from
scrap) with 2 Gb ram and UBUNTU 14.04 LTS. Sound card on PCI bus.
You can see EbSynth settings in the attached screenshot.
Reference signal feeded to EbSynth is 10 kHz coming from Jupiter
GPS.
Time reference is achieved using "ntpd" linux program.
Tone generated from EbSynth modulates the SSB exciter setted on
dial 136000 Hz. Exciter is also Jupiter-GPS disciplinated.
Antenna current about 2 A; antenna type inv-L 8 +8 meters.

Just adding some PTT control into ebsynth ...
Yes, thanks Paul, this facility will semplify the actual strange
arrangements that i have created to activate PTT before and after
the repeated transmissions.
You could do some
very narrow band messages with that - some serious DX?
Yes, i will try in the weekend hoping that Joe VO1NA is available
for these tests.
73 all, Domenico iz7slz
