Please can you list the numbers on the ICs? Is the long one on the right a PIC 16F874?

Thewisepranker thanks for the help input but i dont have access to the board it is just from a picture that a freind send and he is not speaking with me anymore another story .but the only ic identification i can see it 16f876 and maybe lm324

For com0arator i guess because can sense temp swr power fwd and ref and a relay can speed up the fan proportionel to power i can assume that including a password to lock access by user define .

You can buy digital SWR protection with RF power readout boards on eBay and they're not too expensive.

...Instead of fucking about trying to build them out of some old photo why not just buy one of those?
