Nobody seems to talk about Group Delay Time.
The steeper the LC or Xtal filter is, the higher are Group Delay variations.
One filter side up, the other side down.
In narrow filters these are very close.

Looking at the schematic, the only signal that seems to be unique to the

It starts on Control Board U6 pin 34 and goes to P2 pin 15. If it goes

That was about the time it was decided to remove the covers in Aptos to
avoid confusion.
Likely yours had one corner dog-eared so it was obvious and easy to
remove. At least that was the plan at one point. Then it was decided nothing
was gained by leaving them in place and it was just as easy to

I have reached the conclusion that the K3 may be the best data radio

While most revisions to a new letter involve incorporating the items shown
in the errata, there was an additional major change made between Rev B and
Rev C of the K3 Kit Assembly Manual.
The procedure was reorganized to allow builders with the KPA3 100 watt

I am now stopping work and printing a new manual.

K3 concentrates best selectivity here. Correct!
I think you meant that they don't have group delay variations. They
certainly have group delays; they work by adding together delayed

Hi All,
As usual, I decide to do something new with my K2
during a contest! I'll never learn!
Tonight, I'm trying 160m for the first time. Before I
go any further, I should mention that my K2 receives
extremely well on 160. However, when I hit the Tune
button to send some RF to my autotuner
I've been listening in the 160 contest to see how the K3 does in some really
horrific conditions. Lots of very loud stations with awful key clicks
crowded in a small area would crush the front end of most receivers.
I have the 500 hz roofing filter. I can easily get within 200 hz of a
