[amsat-bb] Unsuccessful attempts in APRS through NO-84

[Rocco Labella]

Hi,
I've been trying to make APRS (AFSK 1k2 bps) contacts through NO-84
Satellite, and have been unsuccessful in all attempts using UISS and
SOUNDMODEM.
UISS configured with CQ & ARISS.
Incoming packets from satellite decoding perfectly 100% but when I TX,
satellite ignore me :( .
I've monitored the outgoing audio and adjusted the TX level, with no
results.
Also I've monitored the outgoing audio and i heard a little audio tone
difference between AGWPE and SOUNDMODEM.
I tried also with terrestrial APRS digi and it work 80% good using
SOUNDMODEM and 100% using AGWPE.
Of course everything works perfectly using a hardware  TNC.
I'm coming to the conclusion that this must be a problem with my SOUNDMODEM
settings, because if i use AGWPE, all work fine and NO-84 repeat my packet
100%, without changing anything on the transmitter (TS2000).
Similar results through ISS APRS digi, (a little better)

I would like to know if someone use a similar setup with good results.
