Is there a way to override the fact that the NB needs to be turned on again
each time you change bands? My AGC On/Off setting stays the same regardless
of band changes or powering the rig on off - I'd like the NB to stay in
the position last used when changing bands...
Thanks,

John and all,
The best way to determine a radio's capability to retain settings or
alter its default behavior is to read the Menu Settings. If you don't
have the latest manual, but you do have updated firmware, you will need
to download the latest manual from the Elecraft website.

I had used a home built vacuum relay on 6m to switch between antennas, but the
isolation was not good - possibly due to a problem with dirty contact in the

plenty of power up through 6m with

Vacuum relays can be quite good, as can a proper traditional relay, but all
are only as good as the designer's ability to understand ground loops.
All isolation shortfalls come from either the wrong style relay, or a bad
layout with ground loops or crosstalk between RF conductors. Many of the

Both have connectors on a single flat plate with a design for radically
flowing shield currents from the center common point.
That should, of course, have been radially flowing currents and not
radically flowing currents. Darn auto-correct.

The thing that will take most getting used to will be that the P3 calls the
*bottom* of the scale the reference level. On a typical spectrum analyzer the
reference level is usually the *topmost* line.
Additionally, a spectrum analyzer thinks in terms of reference level and a

Gil,
I assume you are using this preamp with the K3 equipped with the KXV3 or
KXV3A.
Take a look at the rendering on page 3 of the PR-6 manual, and make it
look just like that.
Whatever is currently connected to your RX ANT IN and OUT jacks is
removed and the PR-6 connects to those jacks using

As a former HP/Agilent engineer I agree. Originally the P3 defined REF
LVL as the reference level at the top of the screen and SCALE was in
dB/division. But I got talked out of it.
For a panadapter you generally want to set the noise to be near the
bottom of the display. As you change the

A panadaptor ain't a spectrum analyzer, strictly speaking, and I knew I would
have to change my way of thinking.

Hi Guys,
K3 Serial # 4493 is Up and Running Everything works as documented

My P3 was also ordered on the morning of April 15!! We must be close!!!
