Hi Kevin,
With SSB, pretty much required, in order to get your Tx and Rx aligned with each other and with the others you are talking to. It can be done by computer with half duplex, but the operator on the other end will probably need to work harder.
With FM it's highly recommended, not so much for frequency control, but because it's so easy to step on someone else. Full duplex lets you know you're not the one controlling the channel, so you can back off and let the QSO occur.
Hope to work you some day,
Greg KO6TH

Is Full Duplex really required or just nice to have? Currently my setup (which doesn't include an antenna at the moment due to storms) is a Yaesu FT-790(uhf) and FT-290(vhf). Both do FM and SSB at about 25 watts. I've used to use my 290 for the old RS-12/13 and RS-15 birds along with my FT-890 (RIP) for the 10 meter downlink so I do have "full duplex" but is it a necessary feature? I know it's nice to be able to hear yourself to know that you are even getting into the machine.

There is only one currently operable FM satellite, and many of the sats due to be launched this year are transponders or FM/DSB repeaters.
My suggestion would be to find a Yaesu 817 to get a toe into transponders, and add -any- UHF receiver for full duplex FM. The little Baofeng UV3s are like $45 and have good receivers in them.

Good Day all,
After a few years hiatis, I am contemplating getting back on the birds. Because I currently live in an apartment, I plan on starting the easy route using an arrow antenna. My question is, since I sold my last HT about a decade ago, what is recommended for the current models of HTs that have full-duplex capabilities?
