Many years ago our local fire department used Remote RF Links to connect a Tone Remote handset to our repeater site. The units we used were called Motorola Handie Talkie, they operated on the UHF band and had different TX and PX frequencies, They are 1 watt transmitters and use crystals. I have included some pictures below to show you what they look like.
My question is this. I have about 6 of them that use the same TX / RX Pairs, I was wondering if it was possible to swap the TX / RX crystals in one of the units so that I can get two to talk to each other, as we no longer have the base unit that was receiving the signal at the tower site.
I don't have too much information on these uints, so any info / insight would be great.
My goal with these is to set up a new RF link to once again use a Tone Remote from our Fire Station to the repeater site using these.
The last picture is the back of the main board of the radio.
