2nd RF Module Switch Wafers

The 2nd RF module has two wafers: 4 and 5 counting from the rear of the radio. On the schematic, these switches are labeled SW8-5 and SW8-6/SW8-7 respectively.

Note the filter cap feedthrough on lower left. I have not seen those on any other radio.

For R67 and R72, one radio had 500 ohm (s/n 11883), the other 560 ohm (s/n 31202). Somewhere in there, the ran out of 500 resistors (an archaic value) and switched to 560.
