Sorry Stefan no chance of a test on 136 I have been QRV for local qsos I will put out a call for contacts when I get things going again. I am seeing you regularly sending DFCW on 136. Will be intouch.

Hi Pete, LF,

Pete, the RIG sounds good. Are you QRV on 137 kHz as well? We could try for a QSO if you like. So far i didn't see you there on the band if i remember correctly.

The Rig I described it is capable of much higher power (depending upon output FET currently an IR840?) with increase in PA voltage it's currently got 12volts applied. Because I use 7812 voltage regulators for the logic stages they will only stand about 25volts max, with this rig, limits the power to around 30 to 40 Watts O/P. Suppose I could separate the supply to the PA and get a lot more from the device I supose.

The output goes straight into the aerial 100mm diameter transformer via a short coax lead then to 2 link turns, then from the "Top" of the transformer to the up lead which goes through teflon insulating washers throught the wall and straight up  to the 8inch ribbed glass insulator about 35 feet then on a slope to a 24foot mast (soon to increased to 35feet). Tuned against several long earthing wires.
