Re: BEST satellite radio



Joe,

FWIW, I always TX on the sub-band too.

For me this habit came from the doppler rule of thumb that you 'keep the
lower frequency fixed', and how the radio tracks the VFOs. This is only
true, of course, assuming you're not using computers to track frequency.

As you know when tracking, the sub-band may be adjusted independently of the
main band but the reverse is not true.

This is fine for AO10, RS12/13, RS15 where the lower frequency is the RX
frequency.

I am not however following the correct procedure on FO20/29 where I should
be tuning the RX to a fixed TX frequency.

So the derivation of the rule for the FT847 is that the sub-band should be
higher frequency.

Not sure how easy it's going to be to break my habit.
