Gentlemen,

In following the instructions for the RF "field " alignment of the KWM-2, I have been unable to locate the "driver plate trimmer" for 14 mhz , which is one of the "Group C" trimmers. Each of the other band trimmers are located at the rear of the KWM-2 beneath the slug rack. My 1978, 9th Edition of the Rockwell Collins Instruction Book references FOUR "C"(14) trimmers in paragraph4.5.3.d on page 4-6 and additionally references three trimmers located below the chasis, see para 4.6.5 "RF Circuits Alignment" on page 4-9. However, I have not been able to locate these in the photos included in the manual. Admittedly, I have not had time to get the rig out of the cabinet yet.

Would appreciate it if someone could point me in the right direction. Many thanks for your time.

73,
Dave, K2DP, St. Louis
