I had the fortune to own a Kenwood TH7-D for awhile and would have
kept it if the original owner had not twisted my arm into selling it
back to him (It was for a charitable cause that he was donating the
radio). It was full cross-band duplex with built in TNC and APRS.
Although not an HT, the FT-817 is pretty portable with its carry
strap and works well for working Leos sats. The FT-817 is not
duplex, however, so I would say it is better suited to someone with
some experience working satellites. Being able to hear your own
signal with a cross-band duplex radio helps ensure that you are
And, beginners should remember the first rule in good satellite
operation: "Be able to hear the downlink well, before transmitting!"
A lot of beginners key up their transmitter and cause interference
while they still figuring out how to receive well.
PS: My favorite satellite radio remains my FT-847 (in the
shack)...now ten years old!
