Good Day All,
I have recently purchaced a Heil PR-781, plan on installing it into the
station in the next few days.
Looking at the Heil site it appears at one point they had EQ settings,
however the chart is no longer showing.
Can anyone that has a similar mic give some guidance for some
Has anyone figured out using the KXPA100 to drive the KPA500

I am currently in the middle of converting a D-104 Eagle into a usable mic
and have had a bit of experience in the past with them. I am trying to
recapture a bit of the nostalgia from my early ham days. I paid too much
for it, but not only is the chrome flawless, but it came with the original
The easiest way to use an unamplified D-104 with the K3, or replace a
bad/noisy transistor preamp is this single FET circuit from W9AC:
http://72.52.250.47/images/D104.pdf
The single FET is uniquely suited for the high impedance crystal
element and bias on the mic power. When handled properly
D-104 microphones with the amplifier in the base work just fine with
modern rigs. Look at the bottom of the microphone - if it has a hole
with an adjustable potentiometer below the hole, it has the amplifier.
The Heil rebuild kit is not needed unless the mic element is bad. The
frequency
I might add that if one has an amplified D-104, but wants to remove the
dependency on the battery in the base, that single FET addition can
replace the amplifier in the mic. Yes, I have done that in one of my
D-104 mics. It also works for the K2 when the microphone configuration
header is
The solution is for the K3 to just tell the KAT500 what frequency it is on.
We have all this Elecraft equipment connected together but a lack of
communication between them is the problem.

I do not believe that is the problem. My K3 tells the KAT500 what
frequency it is on as soon as I change frequency on the K3 (or the
KPA500). If not cabled appropriately, then, of course the KAT500 needs a
bit of RF to know what frequency it is on.
The problem is that for some users,
I agree - once you have done the drudgery of setting the tune memories
up for the bands you use, the KPA500 should merely track the K3's VFO.
Seems to me that would be fool proof - maybe???
Change the operation of the AUTO MAN and BYP switches to:
AUTO - will tune anytime if needed
MAN -
Dave,
The K3 does not tell the KAT500 what frequency it is on. It only tells what
band it is on and the KAT500 returns to the last frequency on the band.

Thanks for that correction. Since I do not move around a lot on any given
band, that distinction did not even register with me.

I know very little about how all this works but my guess is that the problem
maybe in the timing of the KAT500 as to when it decides the K3 has QSY'd.
On SSB the frequency will vary quickly as you speak. If the KAT500 sees a
new frequency for too long of a time it may think the K3 has changed

Hi,
I had a few problems in the past (builder's mistakes hi!) with my K2.
Today, I suspect that these problem affect the AGC on my K2 when setting
up the CAL HI and LO, my actuel readings are CAL HI set at 013 and CAL LO
set at 184 when U2 PIN5 is set to 3.8V.
I also found she using the K2
Hi all,
Improvements are being tested. In addition to better verification of the
frequency count, we're going to provide a way for the K3 to send the VFO
frequency to the KAT500 so it can pre-load the LC network as you tune. This
will all be done in firmware.

Is it possible to pull band data off the KX3 and send it to the KAT500 so
it will follow the radio?
Thanks, Dan

Elementary, my dear Watson !
You should listen to FT5ZM :they use K3's and K2's...

Thanks for the additional info guys. I guess I should have posted that the
reason for me to revamp my D-104
was because the previous owner had did some surgery on the circuit board
and mic element. The 9V battery had leaked all over the board damaging it.
So with that I thought it was easier
John,
Which Proset? If it is the ProSet-K2 or a ProSet-iC, then you should
use the electret element Heil uses in their microphone for Icom (those
with an -iC suffix).
OTOH, if you have the normal HC-5 (or HC-4) element in your ProSet, your
choice of the Heil dynamic element will work as you

The AGC Threshold setting between 3.74 and 3.8 volts should work just
fine - do not exceed 3.8 volts. If set too low, the CAL S LO and CAL

Your CAL S-LO setting of 182 is not unusual, but your CAL S-HI setting
is lower than usual - and that is the reason
Thanks for the tips !!!
I always use my XG1. I will try it again, but this time with the preamp on.

Looks like this was because volume turned up too high.
I have tended at times to run RF GAIN backed off quite a bit thus requiring a
hefty amount of volume of about 2 o'clock. I would then adjust RF Gain to the
level of volume I wanted.
