[Elecraft] K144XV REFERENCE OSCILLATOR Phase lock loop option

[Keith Trinity WE6R]

Bob;
You are looking for the K144XV REFERENCE LOCK BOARD, KIT (board, bolt, 
lockwasher and short TMP male-to-male coax).
The KBPF3 is the General Coverage board for working out of the Ham 
Bands, MARS CAP etc and does not affect the 2meter option.
