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. .. 0,00
- 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.
