[amsat-bb] Operating SSB sats

Thu Feb 7 21:38:33 UTC 2019

Good afternoon everyone,
I just did a full reset on my rig to take it back to factory settings.  As
mentioned above about the XIT and the RIT working together.  No change
after doing a full reset of the radio.
So trying to tune with the rit and keep the same TX freq is not possible
from what I can tell based on my observation.
So I don't know if this is different when using a ICOM rig as compared to
the Kenwood?  I would think that you would be able to use them separately
to adjust either one, however, with this I don't know what to do about
trying to keep the correct TX and adjust my RX so that I sound correct or
at least working with something that most would be able to hear without
alot of tuning.  I know that the doppler effects it all, just being able to
set it and not have to constantly adjust with todays rigs I would have
thought would be better then it is even for the age of the technology of
this radio.

Thoughts?
Jim
