Reg, thanks for your fine program,

but.., I get strange values.

When considering the below input-values I get 'strange' results:

- Frequency = 1.8 Mhz
- RF power = 1400 W
- RF peak amplitude = 5400 Volts
- External load res = 50 ohms
- Phase shift = 90 degrees (to get a Q of around 12)
- intrinsic Coil Q = 100

I get:

C1 = 122.5 pF
L = 63.80
C2 = 122.6 pF

Is sounds very strange to me that both C1 and C2 have the same
value whereas the Load resistance at anode is around 10414 ohms
or at least much higher than 50 ohms and an external resistance
of 50 Ohms

What about the Load resistance at anode, I would think this
should be somewhere aound 2800 ohms, considering the Power
output and anode voltage swing.

Arie.
