It might be wise to make sure that you did not inadvertently install one of the .tt4 firmware versions for the MTT4B products, which are not compatible with the standard TT4 devices.

Subject: Re: [TinyTrak] No PTT after upgrade to 0.72
No new PTT setting in 0.72.? I'd recommend you to do a RESTORE to put the TT4 back to a factory state, and see if the problem still exists.? It so, it would probably be a hardware issue, like the PTT transistor, or the JP8 jumper, or the radio interface cable.

Hi, I have upgraded a Tiny Trak4 v7 board to version 0.72 firmware from 0.6. After configuring it I now have no PTT action at the radio. The red led comes on on the TT4 but it doesn't trigger the PTT on the Radio. Note that this was working okay prior to the upgrade and nothing has changed in terms of the radio connection.?
Is there a new setting in version 0.72 for the PTT that i have missed ?
