Ron,
Top of page 3 of my PLL/BFO mod kit (dated 11/15/2002) reads:
"INSTALLATION OF NEW PLL CRYSTAL X1 AND R19"
R19 is jumpered across pins 7 & 8 of RP2 on the RF board, the correct
value is between 1.8k ohms and 3.3k ohms (my kit came with a 2.7k ohm
resistor).
I believe Builder Alert #18's purpose was merely to correct the value
used for R19.
***Happy Holidays***
