Have a MSF500 C74CLB 7106 Tired of running to the two way shop to reprogram. Has anyone tried to convert the anolog station to the CXB by changing the controller board?

Also, I deleteded your duplicate post in the hardware forum - please do not make duplicate posts in multiple forums.

My two bits worth:
The only difference that you need to deal with is that the CLB control board supplies +5V to the receive circuits via ribbon connector pin 9.

In the CXB this line is R-2 strobe.
Install a jumper from the +5V supply to pin 9 of the ribbon connector.
I usuially place a small jumper on the solder side, around the strobe driver, and the collector resistor.

There are detail differences between the various bands of operation in the audio and squelch circuits. I am not sure how this effects performance.

There is a capacitor in the 5V supply on the interconnect board, which is under the RF casting that is likely bad. (1000 uf/16V)

I find that it is easiest to remove the front end casting to get at it, rather than remove the interconnect board.

I can also make code plugs for the CLB, and I also e mail the .bin file if you have a programmer.

Thanks for the advise. I apoligize if I posted in different forums. Thought my post was deleted not moved.
