Hello Mario,

For the TS-790, the MAIN band transmits and receives.  The SUB band is
receive ONLY.

So, for TS-790 satellite operations, you should use:

MAIN band for Transmitting
SUB band for Receiving

It's a very nice radio for satellite operations!  I hope you enjoy it.

Hello folks,
Recently I have in my station a TS-790 for satellites. In the past the
radio used for this activity was a IC-821. On that radio, for sat
activity, is suggested to use the main band for downlink reception and
the sub band for the uplink. This because the reception in main band
is better instead of sub receiver.
And the radio, when sat mode is selected, allow that configuration.
Now on the TS-790, Have I to follow the same setup?
This because, I have done many attempts to use this radio how the Icom
without results.

Tnx for your time
