After mounting L2, T1 and T2 on the RF board, it was time to mount the side panels on the RF board and mate it with the assembled front panel board. This has to be done before the receiver alignments and it is really cool, because I can now see the K1 taking shape:
It seems that the final tests of part 1 of the RF board will require the filter board mounted, so I better get started and assemble that before doing the tests.
