Re: SODA POP source code

Maybe I'll have to give it a try, but once you get hooked on CirCad, everything else seems so clunky and a pain to use. Steve

Re: MTR-5B RTC Battery Buffer Alternative

The alkaline batteries are being used to replace the lithium BACKUP battery on the Soda Pop board, not to be the source of power for operating the radio. On

Re: MTR-5B RTC Battery Buffer Alternative

    AAAA source

    In case any of you folks don't already know it, AAAA batteries can be found cheap. Just break apart a 9V battery. There are 6 of them in each one. Tim - K5DEZ

    Selling my MTR

    Lots of little radios gathering dust here, so I thought I'd pass on this MTR to a new home. This is an original 2-band kit version, covering 20 and 40 meters.
