Subject: [Elecraft] Muting the K2
I am using the K2 on CW
I currently use a Heil ProSet Plus with the dual mike element boom on my
Orion. I want to buy the adaptor for the ProSet to connect to the K2.
The only mention I see of Heil in the Common Question Archive mentions
changing R14 on the KSB2 board from 1K to 10K. But this info dates from
2001.
Hi, Bob-
I don't know if this applies to your situation, or if it is the best
available scheme really, but I use my K2 for RX when I am operating with my
Johnson Ranger TX. The best way I have found to do this is to key both in
parallel, the K2 in TEST mode so that it mutes RX in synch with
As an interim measure you may wish to take a look at K1ELs latest
offering. I built one of his earlier units, but this one seems to cover
pretty much everything!

Hi Tom,
I changed R14 to 5k6 and I am delighted with the results. Without the

The K5/K5B was the last Curtis production keyer. The Curtis 8044ABM chip was
probably the best known Curtis' keyer chip (and their final one) introduced in
the spring of 1986. It incorporated selectable A or B modes and the speed
meter. This truly was a top of the line chip, and became an

There is nothing in the bandpass or lowpass filters that would cause good
behavior below the 10 mHz band and bad performance above that.
I suggest that one of the few things that could cause such behavior is the
VCO. Use CAL FCTR with the probe in TP1 and check the VCO frequency on
For what its worth I bought an Altronix 6030 timer module for $11.00. It is
designed primarily for use in the security alarm business but it has a nice 1

I used the zero beat WWV matching a 500Hz sidetone to the WWV carrier in CW

This is a little off topic, but it follows on the heals of the discussion of
memory keyers for contesting being integrated into the K2 software.
I was using WriteLog this last weekend for SS on a Pentium 233 Laptop. As you
can guess, the CW transmission was slurred because
Hi again Tom,
I use the Heil Proset Plus also with a K2/100 and have left R14 at 1K, no
other changes. My KSB2 was supplied with :

R7 33K ( 3.9K)
R9 10K ( 3.9K)

I have built three different versions of the CMOS Super Keyer kits, sold by
Logikey, and can thoroughly recommend this kind of external keyer. It has
many features, among them contest serial numbers, also automatic character
spacing if you want, signal weighting etc. I never use the built-in

I have used the Logikey for years. Stated as simply

one, your should try it. I'd pay for an add-in of the

PICs are notorious for the lelev of hackery necessary to make things

And!! One source to the info 232 message during cal pll can be that your

Greetings all;
I have completed a KX1 with all options. Everything has gone great
except I am seeing lower power
output than it should be. From a 12.5V power supply I am seeing just
around 2.5W measured with a scope into a dummy load (as well as other
power meters). Likewise on fresh
I would take out the 60m option and try again!
Just to rule out that card.

Mine doesn't.
I NEVER use SSB, but I'm sure I tested the MH2 when I built my KPSK2 ssb
adapter.
Anyhow, at pin5 of the KSB2, no mic, I have 5v (10K pull up). With the mic
plugged in, it's 0v. Is that right?
Pulled the mic apart. No shorts, all lines ring out. The element looks to my

I had this problem when I was first building my K2 a few years back.
I was scratching my head for hours. Finally put a logic analyzer on the

a change was detected, the MPU would snap the VFO back. For some

I did both of these checks as per your recommendation, all readings

I've had Tom's SMD version in my K2 for a couple weeks and it works
great. I just finished testing one in my K1. It also works great, and
may be more useful to me than the one in the K2. All connections to the
indicator are easily picked off J1 (AF from P1, GND from P3 and 12V from
P16).
Hi Ian,
I have not build one but I have all the details its just that its untested
and uses a XV144.
Will drop you an email off list. Thanks for replying.
Best 73,

Well, after following Tom's (N0SS) Cheap 'N Dirty Signal Tracing Guide
