Yaesu FT-2800M (FT 2800 M FT2800M) transceivers: Yaesu mic mod, FT-2800 and others

The annoying lock function doesnt work, only locks the DTMF buttons and the FUNCTION buttons, leaveing the PTT button unlocked for you to accidentally transmit, potentially embarrasing.
Normally you have to go through the setup on the FT-2800 to lock the PTT, but using my mod all you have to do is use the lock switch.

My mod locks the PTT button and the user programble buttons, but leaves the DTMF buttons unlocked when the lock switch is switched on.

The picture shows the solder blobs..

In the factory setup, in the solder joints near the lock button, only D and E are soldered, in my mod, remove the solder blob from D and put a blob over A.

I only tried the blobs untill I reached the point where all buttons worked unlocked, and the PTT was disabled when locked. I dont know what the other solder jumpers do.
