Just What is your question?

There is a good deal of information on the Internet on the Maxtrac. But I will point out there are several low band models, depending on which band segment your trying to use. It is not worth the effort to try to move a Maxtrac from one band segment to another. Too many parts to change to get it to work.

I see what your doing, bit bang the pll for a FPP HEAD.

I did an arduino fpp head for the high band maxtrac converted to 220 MHZ but that was years ago and I lost the notes.

Now I'm curious on the low banders PLL, what is the prescaler modulus of the low band radios?

I know the low band documentation on the PLL is nothing like other MAXTRAC radios but I have some spare 6 n 10 maxtracs to try out and the pll info would help.

If you worked out the low band radios PLL'S N, A and the P counter numbers that will help.
