[Elecraft] Fwd: Re: K3 signal at 28004

[Mike Harris]

Hi,

The S3 signal is probably from within the K3. As previously mentioned I 
have this signal which in my case is 28004.676. Note: I do not have a 
KAT500.

Out of curiosity I changed the K3 REF CAL parameter from the last 
calibration setting of 49.379.892 to 49.379.700 a change of 192. The 
frequency of the odd signal shifted and was displayed now on 28004.559 a 
change of 117Hz. This might give an indication as to why different K3's 
present this signal at slightly different frequencies.

I indicated in an earlier post that the signal vanished when PRE 2 was 
activated, this was entirely due to it being buried by extra antenna 
noise. When I repeated the test with my XG3 which clearly doesn't have a 
load of antenna noise the signal still dropped by an indicated 8dBV or 
so, if I remember correctly, when switching from PRE 1 to PRE 2. This 
still makes me think it is due to a locational change within the box of 
the respective pre-amps.

Does this matter, not a bit. At least it is Elecraft related.

Regards,
