this is strange as most times if a proper transmit key is depressed , then the radio switches from receive to transmit , the mfg know this would cause some great squeal from receiver /transmitting so close to a receiver so the part that is the receiver is muted to keep this from happening , id say there is some fault in the part that does this muting of receiver
It sounds like your circuit board may have a bad solder joint. Sometimes during manufacture of the ciruit board, the joint could not be perfectly made. This will limit conduction and create heat which will worsen the effect over time. If you are familiar with opening and working with electronics then I suggest you remove the circuit board and inspect it for cold solder joints. When you find one, you can use a Cigar Torch type lighter to help reflow the solder easily. Out side of that, you mayu want to send it to a Electronics repair shop to do this for you. Let me know more and I will help. Good luck
The problem is with your power supply. There should be a big round transister on the power supply this is the power transister. It will be mounted to the power supply case. Replace this transister and try to operaste your radio again. Make sure that the power supply you use is at leat 7 amps or the radio will not operate properly and you will possibly blow the transister again.
Sounds like its not wired up right, the audio wire must be off,take the plug apart and check the white wire, re-solder it. here is the wiring, pin1-shield,pin-2audio-(white), pin3-transmit-(red), pin4-receive-(black).....hope this was helpful...
One of 2 reasons. First is common. Your mic or mic jack may be bad. The way the radio works, is the mic switch switched from receive and transmit. When the mic is not keyed then the switch is actually on receive, and when you key it, you switch it to transmit. So if there is something wrong with your mic, or it is not plugged in, the radio will not be in receive mode.
The next problem if a new mic doesn't solve the problem is...
there is an issue with your antenna or feed system. Make sure coax is good. Use an ohm tester. Make sure its not shorted.
Next make sure the antenna is good and tuned properly.
Hello.I have a similar situation on a Magnum 257 HP operating on SSB (AM and FM works fine). If i Transmit it works fine, but when i release the Mic button (after TX), in the bottom side were the RX level should be, it appear somth like a signal level 3 to 5 (constant and continous), but i can't get any reception at all. Only if i turn the TX power level to MAXand i transmit, then it goes back to reception, but not every time. Somtime after TX i need to push the mic button 2-3 times to make it recive somthing, but this wors only if the power level is over 60-70% an i repeat, only on SSB.Can i get some help with this issue?
