My only concern would be RFI from the convertor, and I don't know about their 24v to 12v convertors, but some of the TGE 12V boost regulators have an RF sense feature such that they are active only on transmit, but shut down on receive to eliminate any possibility of RFI.
Thanks Chip! The ones I have looked at, even expensive ones, have quite a bit of voltage sag at rated output. And I think I don't want to screw around with extra RFI problems -- I'm a beginner with HR radio
. I think I'll go with the batt if I can find an appropriate one. Thanks for all your help.
