A number of years ago, Don, my dad bought a small phono-oscillator type thing, where you could specify the frequency of the crystal controlled oscillator. He chose 145.00Mc, because back -then-, that was considered a simplex frequency (sometime in the early 80's). It was built in the covered part of a standard PL-55 jack, with a 'larger-than-normal' covering where the terminals normally connected. The PL-55 was plugged into a headphone jack, and the audio was re-transmitted on the specified frequency. Dad used it to monitor his 40m frequency via his Heahtkit 2m HT. A crystal controlled phono oscillator shouldn't be all that hard to construct. 73 = Best Regards, -Geoff/W5OMR
