GME-Electrophone TX3420 V2.00 Programming software. 

This software is required if you have toasted your tx3420 with the version 1 software. It took me months to track this file down to get my 3420 up and running again. 

the symptoms of a bricked radio is you will find that you will be transmitting around 503 megz instead of the factory 477 megz. 

to fix a 3420 that has been bricked with V1 software...
1. connect and open the Alignment window
2. Open the frequency tab and select 38.4 megz in the freq trim. 
3. dont alter any other settings, save and upload to your rig. 

test all is ok, then you can go back in and program your channels. 

any commments or help email thumper [AT] homebrewham.com.au

thanks
