I know exactly what you said!
Ive never known BW use a frequency doubler style configuration on any of their designs?
I could be wrong though? maybe you could correct me?

Hi,
Before your time probably, but they did mate. I used them before I could do a PLL myself! That is going back, hang on a minute I think I know where I can find it.... Found it:-

Cheers be happy....

The board i made about 15 years ago was using the RF part from BW but the 145170 was in that time expencive and almost impossible to get here in the Netherlands
So i used the "pira pll"with the SAA1057
Changed the loopfilter and made about 100 pieces of this board(for a webshop fmzenders.com)
Later i made many other designs (see picture)
Because i was not happy with the PLL part and osc
2N3866 is not the wright way i think

someone has a diagram and the PCB file for this driver ?
I want to repeat it yoursel

Hello Mr Yellow!
I wouldnt bother trying to build that driver! the time and expense sourcing parts and programming is wasted when PCBwizard on ebay is selling a similar item on ebay!

What output transistor is on that PA?

MRF174. It's 80-100w amp 28v from H

Ahh yes I know the thing, think PCS have a similar circuit.

all the details I have , the circuit synthesizer there seems to pira cz.
I probably do not have only the output transistor in the card , everything else is on the table .
I understand no one will give me the file of the PCB because it is a commercial Projects , and all sdes afraid of competition.
I want to say that in this series , I let the driver do not intend , and interisuet exclusively for themselves .
I am Ukrainian , and I long to wait for a parcel with ebay and expensive for me .
and do not make sense , I myself can collect it , to erase board , flash the PIC microcontroller , customize it .
