[Elecraft] K2 BFO Test problems ( Align. and test, Part II )

[Toni Martin]

Hi all,

In the process to test and alignement Part II, I have
the following issue:  I don´t get the correct range of
BFO values. In my case the set of values are:

- Using CAL FCTR  ...........  4913,63 Khz.
- BFO High Freq. ..............  00000,00
- BFO Low Freq ................  4912,60 Khz.

When I try to set up all filters following the
instruccions on page 93, I  have got the correct
values in CW Norm. and LSB modes, but I can´t get the
correct values in CW Rev. / USB modes. The maximun
value that I can get in this modes is  4914,00 Khz.
The rest of tests included in this section are
corrects

Note:  In my K2 kit I don´t  received ( or I have lost
it  ) the diode D36 - SMT1B and I have replaced it
(temporarily) for an IN4007. Could be this change the
reason of my troubles ???.

Of course, I checked and re-checked the values and
solders of all the components involved in the BFO
schematics ( L33, D37, D38, C169, C173, C174, X3 and
X4 )

All suggestions will be appreciated.
