Continued working on the RF board. I was able to get a lot of the parts installed leading up to the installation of P1. looked all over the place and could not find this part. P1 is used to connect the front panel board to the RF board.
At this point I wondered if I could continue on. Once P1 is installed, the next step is to install some ground jumpers, and U1 (PIC16F872 or 16F872A) which is the I/O controller. After the I/O controller is inserted into its socket, several resistance checks can be performed.
I think that I will continue past the installation of P1, and add the ground jumpers, Install U1, and also do the resistance checks. I can then proceed with pages 39 up to page 42 where power is first applied to the unit. After the resistance checks are made, the next couple of pages deals with the assembly of the case, etc.
When I receive P1, I can solder it onto the RF board and then perform the resistance checks again making sure that I didn't create any solder bridges.
