    Power supply...

    Back in the day, when we were 13 or 14, the group of neighborhood kids all got CB radios. I assume it was because one kids dad is a ham, and he had his dads CB set up in his room. Anyway, I bought this with lawn mowing money, and hooked up my dads old Uniden that he had installed in the 1979 Chevy Monte Carlo. It currently has cigarette lighter adapters hooked up, but I'm going to pull those off.

    Can I use it to power the FTM-350 that I picked up? I'm assuming that because its 40w max, I won't be able to use the radio at full power, correct?

    You'll be lucky to be able to use the FTM-350 at its lowest power setting. That power supply only delivers 1.75 amps. The radio is going to draw at least half that just sitting there.

    The 40w rating is what is draws from the AC line. It's not what the power supply can supply to the radio.

    You can run an HT with it. That's up to you.

    An FTM-350 draws about 12 amps at full output. I'd suggest a supply rated for at least 15 amps.

    Don't junk it. It's useful for something, just not powering your rig.

    You can look at converting an old PC power supply into a temp power supply for your rig. It should handle 10A on the 12V rails. Play it nice, and keep and eye on things, but it should work until you get a proper unit.

    I'm going to be putting a used Astron RS35A up for sale for a fellow ham/widow as soon as I test it out. She's not looking to get the moon out of the thing, just a reasonable figure plus shipping.

    That supply will more than handle a VHF rig and a most 12V HF rigs.

    Let me know if interested.

    I'd take Fred up on the Astron offer. I have several, and they are pretty much bomb proof. But if one should ever go TU on you, they are a cinch to fix.

    Price is going to be key... I'm pretty much on a non-existent budget.
