I'm also a MARS op, and have used the KX3 mobile for MARS ops. The
only issue I've found is making sure that the antenna is resonant.
Hi Alan,
I would guess that running Peak on the P3 and having the S meter on
the K3 set to PEAK ON should give roughly the same results. Correct?
Or does the same discrepancy you advised below exist? Peak and PEAK
ON similarity is what I'm seeing here on the K3 / P3.

this: Set the K3 to the normal 2.7
kHz bandwidth, tune in an SSB signal and note the S meter reading. Now
change the K3 bandwidth to 100 Hz and note the S meter reading. It will
be much lower.

I'm using two solar setups. One is a 100W system for the K3 and KX3 /
ham station generally. That's probably not going to interest anyone
for portable ops with the KX3.
Five or so years ago, I bought 80 4.5-inch wafers from a 2nd tier
outfit in New England. From these, I built two panels that

Does this mean you'd be willing to pay the RD costs, or just the list

In my experience with Elecraft, the principals decide what a product
line includes. I doubt that style-matched speakers is on their list
of 'must do' items, but I don't speak

I like it! I left my settings in RX NR alone, and just used the
multifunction control. I found the whole range was usable in CW and
SSB. At the higher levels, a bit more AF gain is needed.
Next, I'll put the noise source outside near the doublet and see if I
can tune around and pull sigs out
There is/was a flowchart for this type of troubleshooting. It used
coarse language, but followed this same type of logic.

Best used when copy any other way is impossible due to a weak signal.
Ringing is somewhat better than noise, isn't it?
I've found APF useful in a number of QRP events, when handling weak
signals is the order of the day. Yes - copy may be dificult but at
least you have something to work with.
I should have mentioned that APF is set the way it's set. I don't
believe any parameters exist to change APF's operation. Someone may
correct me on this.
APF is best used with a narrow bandwidth setting. I think I saw the
figure 30 Hz (for -6dB points) used in conjunction with APF, so a 50

I'm using it in a mobile setting to isolate the KX3 from the vehicle's
electrical system. Pretty good results, and no hash.

There is also the CirKits SCC3 solar charge controller. It scales
from 20A to 60A pretty easily. I use one for the shack solar to
charge an Optima AGM battery.
The SCC3 is a kit, quick and fun to build. You have to supply your
own housing though.

There will be a lot of chaff coming after your post re compilers,
Dick. For my own part, I *try* to stay with supported operating
systems. Can't always do it that way, but today I'm running Win7-64.
W7-64 will handle Win32 of all stripes. Until recently I was running
XP, but it was about to go

You will need to send a copy of your MARS credentials via scan or

The region (spectrum) from 7.5 to 9.0 MHz is hard-locked out for TX
though, being too near the IF to be usable or safe for the K3.
Gary will send you a utility program that unlocks TX up to 25 MHz.
There is a second utility
To put your K3 back into a usable state:
0. Kill the KPA500 utility program. This should leave your COM3 free
for the K3 utility. If it doesn't then reboot the computer.
1. Remove the K3 power and leave it disconnected for 15 seconds or
so.
2. Re-connect K3 power and hold the K3's power
