I recently purchased a heathkit dx-40 that works great. But some mods have been done. It transmits fine. Its supposecto have a ptt mod done, it has a four pin mic lug. Pin 1 is the audio and pin 4 is one of the two grounds from what I have found out. When I put it on "phone" and it is just keyed all the time, even though I dont have anything pluged into the mic lug. Shouldent it not transmit in the "phone" position till the relay has been tripped? It has an internal relay for keying thats part of the mod.
Any ideas? Maby I am missing something....
