Radio powers up but no receive or transmit.Wires on power supply were loose making the radio flicker on and off right before it happened.Any ideas?? |

Does the TX lamp turn red when you key up? Sounds like the shield is broken in the microphone cord...

No-theres no receive or transmit at all.Light doesnt turn green when i key up or red when i unkey-nothing.It was working perfect before it started flickering from a loose connection on the power cord.Light in meter and channel led comes on but thats it.Maybe popped a safety diode or something??? |

Yes..If it has no "green LED" on RX , it has a busted trace OR the 8 volt regulator which powers the PLL , LED and Oscillators is dead...

IC4 , MB3756 should have 8 volts on pin 1 with the radio turned on...
