N0SS Zero Beat detector too active

[Don Wilhelm-3]

Folks,

I recall seeing a post sometime back about reducing the input to the
N0SS tuning indicator, but I have not been able to locate it.

As I recall it was only a series resistor, but can someone tell me the
value used before I begin re-inventing the wheel.

While I have K2 SN 00020 open on the bench, I would like to add this, my
zero beat indicator is way too sensitive.

73,

Don,

You cannot possibly imagine how pleased I am to be able to answer one of
YOUR questions!

The resistor is a 93.1 K and is supplied as a SMD.

73,

Tom

Don,

As I look over the photo that came with the little SMD I see that there are
really two options, one placing the SMD on the N0SS board and another
putting a couple of 47 K resistors in series on the K2 board where the
output goes to the N0SSoard.  So, I guess the exact value isn't critical
-93.1K - 94K - what have you.

Tom and all,

Thanks to all who responded.  I promise to make a permanent note of it
so I can refer others to it should they ask (I just can't remember
everything, and I have earned the 'senior moment' excuse to fall back on
if necessary <G>).

The collective memory of this group is a valuable resource.  Thank you all.

73,
Don W3FPR
