[Milsurplus] URC-104 TXCO needed

[Ray Fantini]

It's a long shot but will try anyway. I have two dead URC-104 transceivers in the shop at the same time. Both have the exact same problem. The 200 MHz TXCO that's used in the transverter has died. It's a sealed metal can about half the size of a pack of cigarettes that when supplied +12 volts generated a 200 MHz signal that was used in the transverter to heterodyne incoming signals from 30 to 70 MHz to 230 to 270 MHz that's in the URC radios normal receive range along with heterodyning them back at a low level in transmit for transmitting on the low VHF band. Have a bad feeling that I am going to have to get a couple of the little TXCO assemblies that were built for computers and modify them for use in this circuit but in this type of use stability and the ability to be right at 200.000 is fairly important. Have not seen similar failure in the URC-110 or 101 just the 104, go figure.
