[DCboatanchors] [MOPAGROUP] 50.3Mhz CW project:: 5-10Watts but I can not "listen" to the signal on the freq.

Hey Hanibal,

What frequency is the "oscillator signal" please?

What is your signal source? A Crystal? A VFO?
If you have a crystal is running at say, 8.3833 MHz X6 to get you to 50.3 
MHz
then you will need a tuned multiplier stage somewhere to get the signal to 
50.3 MHz.

If you use only an RF Choke in the plate circuit of the oscillator then you will 
still
only have 8.3833 MHz coming out.
