I found an article a while back that extolled the virtue of running with
the volume all the way up, but the RF gain down. That way, you don't
amplify the noise along with the signal, if the signal is sticking up out
of the noise at all. It works pretty well! I'd get so frustrated trying to
keep
I just had a graphic demonstration of the fact Bob mentioned when I was
just rebuilding an old R-390 receiver a few weeks ago. I was pleased
that I saw an AM sensitivity (30% modulation in a 4 khz BW) of 0.49
microvolts for a 10 dB S/N ratio at 26 MHz. I then realized that I had
the IF gain
In writing this, I do so, saying that I find the method to be excellent
and reliable and repeatable with regard to HF radio receiver operation
for all modes.
In general it seems that hams have the more incorrect notion or idea
where more gain is needed to hear a weak signal. To some degree
You can reduce the LIN OUT level via the Config menu in the radio.
Normal is 010. I would back that value down.
I use Windows 10 thus I have full control of all levels via the
computer. Also I use the USB connection between the radio and computer
and do not need a Signalink.
I can't
There is no reason to always run RF gain at maximum. Otherwise
there wouldn't be a control.
I have always set up FT8 with the gains about 12 o'clock and
adjusted the RF gain so the signal strength meter in wsjt-x is
about 60 to 70. This adjustment gives the maximum level for the
weak signals
The Elecraft K3s manual states over and over that the RF gain should always be
wide open. I had been running it at about 12 o'clock on FT8 for some time
before this was brought to my attention. I supposed that 100% RF gain could
possibly show me weak stations I’d not seen before, so I’m trying
I ran into this exact issue caused by cable connections, specifically
the Y-cable that didn't allow the connector screws to join the cables.
Getting the Y-box from N6TV solved the loose cable problem.

Check the AUXIO cable to make sure it connects to the K3S and the KPA500 (or
KAT500) properly. This sounds like the Band1 signal may not be making proper
contact.
The KPA500 watches the K3S’s Band signals for its band selection when RADIO is
set to K3. If doesn’t see the combination for

I would suggest doing a Direct Frequency Entry into each of the ham
bands - no guarantee, but it has a chance of setting things straight.

Having a bit of trouble with the KPA500 following the bands out of the
K3S. For some reason, the other day I accidentally hit a button
combination on the K3S (not sure what I hit) and the KPA500 is now
thinking 7.0 MHz is 1.8 and some of the other bands aren't switching
correctly either. I
I am in the same situation and could use 2 as well.

I recently purchased an older K3 as my rig to take to our clubhouse. So
it does not need to have all the bells and whistles. However, I note
that Electraft no longer sells the mechanical strengtheners for the
original synthesizers (and I have a sub receiver so I have two
synthesizers).
So
Hi Don,
I do have the SVGA option installed but do not remember upgrading the K3
for 1 amp. Not sure how I missed that upgrade. So in a few weeks will be
opening up my K3 to check that and if not there putting in the upgrade.
Thanks for your advice.
