[Elecraft] BFO Test - CAL FCTR

[Pierre Desjardins]

Hi to all Elecrafters

I recently built K2/100 # 5170. At the BFO Test (page 62), using CAL FCTR, I got correct readings: Center at 4913,55 kHz, BFO High 4917,23 and BFO low at 4912,41 respectively.

But something new is happening. The readings changed to  4913,85 (C), 4915.97 (H) and 4913,58 (L).. so that the narrow filters (<1 kHz) are almost impossible to center correctly. I use the Spectrogam method to adjust the filters.

Where should I look to get it back to the previous range?
