Motorola HT90

[mario_verasso]

Wasn't sure where this should have been posted. I just inherited a HT90 2 way radio from a friend of mine. From the research i have gathered that this radio is only a 2 channel crystal type of radio. The operating freqs listed on the radio Ch#1 468.5375 tx / 463.5375 rc / Ch#2 463.5375 tx / 463.5375 rc. The radio is stamped Feb. 84, can anyone pass on any other information about this radio?

It's a UHF radio obviously setup on a business repeater, maybe someone in the Dallas area can help you identify those channels.

They are usually 4 watt transmitters (Models beginning with H34) they have PL and they use a 12v battery on them that connects to the back of the radio. Frequency range (transmit receive) is 440-512Mhz.) The receiver will usually only spread 1 MHz and the transmit frequencies will spread only 5 MHz with no degradation. I Like the BNC Antenna connector. You can feed it into a base station antenna and get more range. Hope this helps

This frequency has been used for Medical Ops at the State Fair the last few years although the official license says Medical at Reunion Arena.

They were great radios to work on on the bench; simple layout, only a few problems that were really very common; the pins of the PA had a tendency to break, probably if the radio was dropped on it's bottom. Tune up was a breeze; couple of test points, peak/dip/peak/dip/etc., adjust the crystals to freq. (crystal leads breaking was another common problem, esp. if a previous tech had not put the little plastic pad underneath the crystal)

What are your plans for them? Re-crystalling them will end up being pricey, compared to buying even a used synthesized radio, but the learning value would be great. I suspect they would go down into the 440 ham band pretty easily; tho I don't know that for sure.
