    I see that most 2m amps have a toggle for fm or ssb. Is it possible to do ssb on a handheld with some sort of amplifier or other equipment?

    It would only be possible if the handheld was built to transmit SSB. I'm not aware of any that are. There are mobile size radios that do. Icom IC-271, Yaesu FT-817. Possibly others.

    No, sadly, I'm not aware of an available HT that will do SSB - I think the closest thing would be a Yaesu FT-817, which is battery portable.

    FWIW, the SSB setting simply delays the T/R sensing so that a pause in the SSB does not return the amp to receive.

    The smaller amps are also great for older 2m mobile rigs, that were only 5-10w out.

    Look at Rigpix.com. You'll find quite a few "mobile" non handheld 2m "All mode" rigs that are under 15w's output.

    Just the kenwood ones I know of: TR-9000, TR-9130

    Only if the HT can do SSB.

    A few such HT's were made, but as far as I know, none are being sold (at least in the US) at present. The FT-817 comes close, though it really needs to be hung from the shoulder or neck for portable walkabout. With a decent multimode (linear) 2m amplifer and some efficient batteries you could have some fun on the mountain. (Or even without an amp.)

    The reason for FM/SSB switches on the amplifiers is to set the RF-operated TR relay time long enough to prevent relay chattering between SSB syllables or words.

    I do have an FT290, battery operated, and like FT817, they are more of a "backpack"HT's than mobiles.


    Even FT897 fits this description (if you push really hard to fit it in, hihi....)


    in any case, QRO HT battery operation is not as a viable option, since safety, endurance for prolonged operations and some reciprocality (call me antenna gain) must be considered for overall field operation planning.

    The TH-F7 has a SSB-capable receiver, BTW. some VERTEX HT's come with 1W AM.

    Maybe some day someone will shrink circuitry down to the point that 5W SSB HT on 2m/222/440 would be plausible.

    The FT-817 already does this on 144/432 but not 222. Pity, because that "could have" been included, but they didn't do it -- probably because 222 MHz is a ham band only in ITU Region 2, and not in Japan.

    I remember a ten meter and a six meter SSB hand held radio; however for the life of me, I can't come up with a manufacturer's name. IIRC it used a VXO (Variable Crystal Oscillator). It was a somewhat boxy affair similar to some early business band hand-held radios. I remember seeing one at a hamfest a few years back.

    There was a SSB CB handheld, the Cherokee AH-100. I don't know if it is still made or if it is a candidate for conversion to ten meters...by a licensed amateur with ten meter privaleges, of course.

    The olde Icom IC202 (2m), IC402 (70cm), and IC502 (6m) while not handhelds, were battery portables that operated SSB & CW. Icom also produced the IC505 (6m) that was an all-mode portable.

    Could the SSB handhelds be AEA?

    AEA made some boxy little plastic radios for 6 & 2M, I should dig them
    out of the bin they are hiding in. ( maybe?? ) Reminder: there is no 'free lunch', battery powered rigs run shorter TX time in smaller sizes. Timewave purchased AEA except for antennas & analyzers.
