I found the 1.8k is too narrow for running stations at high rates (>150 per

Thanks, Don.
I should explain a bit more. In fact I confused running bw down to
2.1 or 1.8 KHz with running the NR function. It is the NR which adds
what I termed "audio distortion" to the signal and not narrowing
bw. At least not at 1.8-2.1 KHz. Ringing below 50-Hz makes it

While it isn't the exact same model from MFJ, my -962D has issues tuning my

Hope this helps.

Hi Jim,
A good generic textbook explanation, but the feature of interest here is that
using the "apostrophe" setting REDUCES the noise floor. I am not changing the
overall gain.
The overall gain of FP.H at a mic gain setting of 35 is about the same at using

My guess would be that you are more significantly inconveniencing the

Higher loss components in some cases, but designs that produce
sub-optimal L-C ratios in others.Check the QST review of high power
tuners from a few years ago if you don't believe me, and then do a
Google search for melted inductors in MFJ tuners if you still don't.

Allen, is this hesitation present when you are keying the WinKey USB (is it a

Since you have decided to go with the 2.7 filter, you have a couple
