Re: DX and antenna
Look up QRPGuys on Google - they have some EFHW kits - might be a help.

B-5.81V
C-11.91V
Amplifier Transistor
E-2.94V
B-3.61V
C-11.84V

Re: Farhan VU2ESE'sTwo Tone Generator
We are discussing the rf two tone generator. The emitter should show at
least 500mv of RF.
I still suspect measurements. It is like this, the oscillations need the

Looking at the schematic of the output combiner, are you really using 150 ohm resistors for a 50 ohm system? Every similar output combiner I have ever build for a 50 ohm system has 50 ohm
