Dear Elecrafties,
I recently whinged about the K3 using the wrong sideband for CW, for me
anyway. I prefer tuning from the bottom of the band upwards, hearing
successive CW tones going high-to-low as I go, which requires CW-REV on the
K3. That's fine, until I click on a spot in Logger32: as
Hello,
My name is Gerard my call sign is F6CVM and i'm a K3 + HEATHKIT SB 230 linear
amplifier user.
Unfortunatly, the KA-3702 relay is out of order,so i need to get a new one, the
accurate reference is :
Potter and Brumfield KA-3702 110 Volts.
Can you help me to get a new one, because is

I would first suspect a voltage drop at the rigrunner (and its fuse)
rather than a failed PA transistor. Check the voltage at the K2 end
under full current load.

The cable is actually the one I made up for the K2.
There are several problems in the setup. First, the K3 connector shells

Hi Tom,
I'm beginning to wonder if it might not be due to shorting out the chokes
for PC out and PC in of the RS232 connector whilst doing the rear panel RF

The problem is I don't have a before benchmark. I can now hear PC

I figures that you ZL guys would use CW-Rev and prefer hearing the pitch go
down as the frequency goes up. Up here above the equator, the default
setting, CW, seems more natural to us. Now tell me, do whirlpools,
hurricanes and toilet swirlies really run counterclockwise down there as

I put an item in The Doctor is IN in Aug 2008 QST, p 63, on hints for
assembling APP connectors. In addition, there is a photo of how I keep stressed
Powerpoles together using a 1/16 inch tie wrap. In addition to keeping the
connectors mated, it also keeps the pairs together as does a

The fact that the radio (and the amp) key when I'm playing
with my paddles and just wanna hear my own CW.
Me too.
I guess it must be done this way for people who send the key first to
their amp or antenna switch, and then get their PTT
If you don't want power output when you hit the key, turn off the VOX while
in CW mode - the rig responds with PTT in the message area. To get power
out with VOX off, you must press the XMIT button or active the PTT (with a
footswitch, for example) while keying the paddles.
Depending on what you
That isn't the problem. Even if you have VOX off, hitting the paddles
activates the T/R relay line to the amplifier. It does so even if you
put the K3 into TEST mode. There's no power output, but the amp relay
(and anything else that may be activated by PTT) engages.

I guess it must be done this way for people who send the key
first to their amp or antenna switch, and then get their PTT
back to the radio from it? Like from an extra contact pair on
a relay that bypasses a mast-mount preamp.
It is Key Out - not amplifier PTT. The difference is subtle

That's right - it does. Again, the signal is Key Out not
Amplifier PTT. Key out should ALWAYS follow the straight
key (or internal keyer) input regardless of whether the K3
is producing power.
Actually, it follows the logical OR of XMIT button and key.
One of the four resistance measurements (prior to the initial power on / smoke
test) is low by about 30% ...
1. The resistance across the power pole connectors is ~1.1 Meg Ohms (looking
for 50 k Ohms). (GOOD!)
2. R36 to ground was only 108 Ohms (looking for 150 Ohms). I tried reversing
Has anyone found a practical way to secure the Powerpole connection to
the K3? I manage to dislodge mine all too frequently.

Look at the Anderson Powerpole jack on your K3. One of the lugs on mine
was not extended far enough outward to allow it to seat properly because
the lead going to it was too short. Rather than remove the previously
soldered wire and attach a longer one, the installer merely
Art Collins had his bad days, too.
For Art, that day occurred when riveted RCA phono connectors were chosen for
the RF antenna ports on the S line -- just as Heathkit did on the HW-101.

Hi Jim,
I have your paper and will have another read. I've been meaning to make
up a new cable for a while.
The noise has only become noticeable since I increased the sensitivity on
6m and if I switch out the PR6 I can't hear it. 6m is reasonably quiet
here, particularly when I beam out to
Earlier I posted that R36 to ground was only 108 Ohms ...

default or change in some way some of the settings I have programmed in?

Yes, you can save the configuration using the firmware utility. I
have not noticed many config changes. In the past (many releases ago)
a few items changed on occasion, but I haven't noticed anything like
that for quite a while.
