I have a copy of the 725 manual as well as the maintenance manual but there isn't much mention about the break in function and the schematic is so small that I can't read the part designations.
I just tried the rig again this morning. Yesterday I had set the TX delay pot for short delay with the semi break switch on. Today when I powered up and pressed the key, the rig the T/R relay switched and the TX light came on. With key up, the rig went into RX as expected. I cycled the CW break several times into a dummy load and it worked ok and then after a short pause, the receiver didn't come back!
I cycled the power switch and the break function again worked but quit after a couple of CW cycles. I now think there may be a bad capacitor in the timing circuit?
Does anyone have a suggestion?
BTW, the IC-725 has PTT only. No VOX!
Thanks for your help...
