Ok! I have done the mosfet conversion with "peak&tune". Here's the deal! I have also done the talkback mod where you solder the top of the 2 resistors together to make it louder & for some reason I just noticed today that when I am just listening, if I turn the talkback all the way up, it increasesthe volume of the receive. (Not the S units. Has anyone else noticed this? Radion is transmitting & recieves well. Also I did try the homebrew dipole on my semi. & it works very well
