sat_mode values

[KK7A]

What is the definition of the different values for sat_mode?

HV
HU
VU
VL
VS
UV
UL
US
SX

Guessing it has to do with the TX/RX bands, but not sure.

Thanks, Jim - KK7A

It must be a mystery.

Not seeing it in the documentation and general Internet searches don't talk much about it either.
