[Elecraft] KRX3 questions

[Arie Kleingeld PA3A]

Lyle,

I can understand why the beat effect can happen at certain frequencies.
I read the message about the rounding errors.

My question is: can you give an indication of how often this happens. Of
course it depends on freq and filter offset but still, can you give an
idication how bad it is.
Anyone ?

Thanks.

Yes, but set them both to the same value. A 10 Hz error is not going 
matter to the 2.7 kHz filter's passband response, but the 10 Hz 
difference in offset may result in an annoying beat effect when both 
receivers are tuned to the same indicated frequency.
