boatman Posted October 13, 2011 Share Posted October 13, 2011 It should be a fairly simple mod. You need to attenuate the headphone output of the Tecpro beltpack to match the external mic input of the radio and attenuate the external headphone output of the radio to match the mic input of the Tecpro beltpack. As you are a student, I'm sure you can calculate the necessary attenuation levels for each signal. Unless you want to use VOX on the radio (which I wouldn't recommend), you also need to wire a relay coil across the signal lamp so that its contact can act as a PTT button. On the other hand you could hire a Tecpro AD913 which is purpose designed to do the job. Link to comment Share on other sites More sharing options...
