Hope nobody minds a newby breaking in.
What is the theory behind changing the higher frequency, or is it just an operating convention?
Also, what is a good beginning HT to use to work the sats? I have a little Baofeng UV5R variant. My family got me the Elk dual-band log periodic antenna so that is good, but am I screwed with the radio?

Thanks guys. That is why I am asking. After this past weekend of operating and a few conversations I noticed something wasn't right. Makes total sense to adjust the higher frequency.
Keep learning every day and every pass!

Always tune the highest of the tune frequencies.
On Mode B, tune your transmitter and maintain a constant downlink and on Mode J, tune your receiver and maintain a constant uplink.
This keeps you from drifting too far and possibly into QSOs of people using computer control.
Much to my dismay, some literature, including the most recent edition of the ARRL Operating Manual still include the outdated suggestion to always tune your transmitter.

Seem to me back then when we operated linear satellites (FO-29, RS’s etc) we found ourselves on the receive passband and as the doppler changed we adjusted our transmit freq to make sure we stayed on the receive frequency.
Of course things have changed since then and many use some sort of satellite tracking software to control the doppler adjustments on the radio. But when you are operating portable what is the proper procedure on the linear sats?
Thanks,
