Hi Elecrafters,
I am ready to key my Drake L-4B using my K2/100 but I read from a previous post:
If you already have the KPA100, look on the rear panel and you will see an RCA
jack marked PA KEY OUT between the ground connection and the power connector
- this will allow you to key your external
A simple way to find out is turn the amplifier on and measure the voltage on
the keying input on the amplifier, noting the voltage and its polarity. Next
switch your multimeter to measure current and connect it to the same place
on the amplifier. The amplifier should key and you will see how much
Ariel (and all),
I don't know the specifics of that amplifier, but one can make a quick
measurement to find the answer for yourself.
Turn on the amplifier and measure the voltage at the amp's Keying input
with your DMM. Is it positive or negative? How large is the voltage?
If you are
All,
I will be net control today from the Metro Atlanta, Georgia, area. Please
adjust your beam headings accordingly. I look forward to hearing everyone
at 1800Z on 14.3035.

I changed over to the 10-6 K3 preamp, and now have a PR6 for sale. I have the
original box, plug and BNC connectors. I'll send it to someone for $145 from

I am considering getting a KAT500 to provide me with higher power auto-tuning.
Currently, the KAT3 is capable of achieving a match on all bands using my
open-wire fed 160-meter dipole, with some help from a 4:1 balun. I believe
both tuners are T-matches, but I don't have enough information to
Gary,
Both tuners are L-C or C-L with the cap being able to be on the transmit side
or the antenna side. The L and C values can be found in the K3 schematic
package available on the Elecraft website but, so far as I know, the KAT500
schematics haven't been published yet.
I would expect, that

Essentially the same lumped values of L and C and hence the same tuning
range. The distributed reactances inside the larger tuner are somewhat
different because of component size changes, so there are some minor
differences that show up on 6 meters mostly.
If you install the KAT500 Utility
Looks like another tinyurl (my) buffo. I'll correct this link and
re-post. Sorry.

My K3's internal ATU will match 40m to 6m fine using a 66 foot doublet
but my KAT500 struggles a bit on two bands using the same antenna
configuration (with fine tuning), it tunes the remaining bands fine.

FWIW, my long-winded and slightly-meandering KX3 review:
http://n6ol.us/blog/2013/08/the-elecraft-kx3.html
I wanted to get it all written down while it was still fresh in my head, so
it comes after only a week of playing with it. Hopefully there's some
helpful information / hints / suggestions
The KAT-500 utility shows C Values from 8 to 1360 pf ( ~2600 max ) and L
values from 50 to 9000 nH ( ~18000 max ).. I assume that is what is in
the hardware.

Good Morning,
After a chilly week the temperatures are climbing back into the
upper 60s again. It feels good not having to heat the house. Summer
should be a time where I can work on my garden rather than carry wood.
It was nice to receive some precipitation though since fire danger was

Here are the results of today's SSB net. For a change, I had decent

Mike,
The best use of the 'scope is during the transmit bandpass filter
alignment - just connect the 'scope (with a 10X probe) across your dummy
load, and use it to indicate the RF amplitude - that is faster then
looking at the slower to change display on the K2.
If you have the KAT2 option
Don thanks very much for taking the time to get back to me and I will use the
scope for the procedures you indicated.
Mike

IF your scope is well calibrated you can use it for many d-c measurements as
well.
Whenever I'm adjusting a level for a peak or minimum reading, audio or dc, I
prefer my scope instead of a DMM because the scope is instantaneous and
provides an analogue (moving trace) instead of a digital
Hi,
After installing the roofing filters in my KX3 (which was a while ago), it
seemed to me that the received audio was down somewhat from the levels I
recall from before the filters were installed.
At the suggestion of another KX3 owner, I tried the following experiment: I
hooked up my XG1 signal
I use one of the following antennas:
1. A home brew Carolina Windom for 40 up 35-40 feet.
2. An interlaced 40/20 meter delta loop, apex up, base ~6 feet over ground, and
fed at a corner
3. An 18' vertical with 2 9' radials fed at the vertical base which is ~15'
feet above ground.
