A Radio Club friend attempted to have an UHF MCS2000 radio he picked up from a Hamfest for $10.00 repaired and he was unsuccessful in getting it repaired. He is willing to give it away if anyone needs it for parts before it goes to waste.
The radio will key and transmit 40+ watts by tapping into the accessory connector, just not through the microphone RJ45 connector port.
Here is the report on the repair attempt:
“Troubleshoot no PTT voltage at microphone jack.
1.35 mV at microphone jack on pin 6 (PTT). D0667 protection zener is OK. No 5V supplied, possible other issue.
0.47 mV at microphone jack pin 3 (monitor/busy/KID).
D0668 protection zener is OK. No 5V supplied, possible other issue.
Power cord is installed backwards. Red lead connected to ground, black lead connected to B+.”
Let me know if anyone is interested in this radio. You can reach me by email at: nokones@kenmitchell.com
