[amsat-bb] FT-857D and PstRotator

[Hasan al-Basri]

Loon,
The 857d will not accept CAT commands while in transmit, no matter what
software you use. I use with CAT, and set vox for 100 ms drop out...so
every time vox drops (PTT is no longer asserted), the CAT command is
accepted and doppler catches up. Works just fine once you get good at
"pausing".

It is a hardware limitation of the radio, so you have two choices:

Use PTT and drop it frequently, or use Vox set to very short delay and let
it drop PTT for you.

I have no trouble running CAT (used both PST and SDRC)...again, no program
will let you do doppler correction on the FT-857D while PTT is asserted,
but you can get really good at letting or forcing PTT to drop often enough
that it becomes nearly transparent.
