Problem w/6400 and PTT

On a previous post, I indicated that my 6400 was having issues transmitting with the included stock mic. Well after further review, it might be a PTT issue. I purchased a PTT switch and hooked it up to the RCA PTT jack on the back of the 6400. Currently I can transmit via my PC headset by clicking the MOX button and it works fine. However, pressing the PTT switch I connected, it is doing the exact same as the stock mic which was connected to the same PTT jack. No audio or modulation during transmittion. Am I missing a setting? Or is there a potential hardware problem? Any Ideas? Thanks!

Have you checked your TX settings are set to enable? Settings - Radio Setup - TX - RCA TX 1,2,3 I have a 6700 but your rig should be similar0

Thank you for the reply. They are all enabled and set to value of zero.0

If you MOX button keys the radio, then the rear PTT , should also work, time to turn in HelpDesk ticket , http://helpdesk.flexradio.com .0

I had a similar intermittent problem, and solved it with a very slight squeeze of the RCA barrel using a set of pliers. It apparently wasn’t making solid contact.0

The PTT triggers, and the radio goes into transmit mode, just no modulation as it does via MOX. I opened a help desk issue. I don’t want to do anything that might void the warranty. Thanks!0

Check that the Microphone selection (Mic/Bal....) matches how you have it wired.
