HT1250 Troubleshoot

[Depchief11]

I have several HT1250s that you can not transmit voice over the extenda mic. Through the radio its fine. Using the mic, it keys up but no voice transmits but yet you can receive voice over the mic. Now when you bend the cord of the mic 180 degrees downward, at the conection to the radio the mic will work. When you let it go, it stops working again. The mics are good as they work with other 1250s. And other mics that work on working 1250s won't work on the troubled ones. We are using UHF fregeuncies and it does it for repeated and talk around frequencies. Anyone have any ideas?

Perhaps the pin on the connector does not make contact with the contact area on the radio. When you apply a little pressure, it makes the connection??? Maybe the contact area is dirty, clean it with a pencil eraser.

We thought the same thing but it wasn't that. It only works by bending the cord and only on that radio. The mic works fine on any other radio. I'll try to post a pic.

That would suggest that the issue is in the radio, time to take it to a shop to get looked at

Just a guess, but what I'd look at is the accessory connector. It consists of the flat piece you can see on the outside of the radio, which is actually flexible and only stuck onto the case with adhesive, and a flex cable attached to it. If the flex connection has gone intermittent on the Mic Hi line, but when you push on the mike connector cable it forces the radio connector just enough to restore conductivity, that would produce the phenomenon you've described.

It has been a while, but I believe that accessory connector is one of the items included in the HT1250/1550 refurb kit.
