Hi Elecrafters,
my new K3 #4739 is ready and works fine. Only one problem is the band switch.
Switching the bands up by pressing the right side of the bandswitch works very
well. But for switching the bands down you need a lot of pressure, so much that
the K3 moves backwards on the table. Any

follow-up email.

All of a sudden, I'm having trouble with the K3's receiver following RF gain
calibration and S meter setting. The RF gain calibration using the utility
leaves the receiver with S9 at -73dBm (using ZG-2) but when I turn off and
then on the K3 the S meter drops to S7 and the RF gain control,
As indicated in my previous email, the K3 works well in FSK D mode.
However, I think I may have discovered a (rare) bug in the firmware,
that has been 'bugging' me for a long time! If I am right, I believe this
issue could have been there from the beginning. I have K3 #936 and I

John - found your post interesting and timely, as I played around with the CW

after number of years. I have a feeling I threw off some of the

I built a kit K1 80/40. Everything was no problem. All values of resistors
and DC voltages were OK. But in chapter 9, part Band 1 Allignment,

I changed it and after that I measured current - 0.1 W on 3.6 MHz current

Keith,
This shouldn't happen. I test this on every firmware release, and just
tested it again. Enter CW mode, then hold the SPEED/MIC/MON knob in to
bring up sidetone MON level, then adjust it. Tap the knob to return to
normal operation. Changing modes and possibly readjusting the MON
Elecraft must be having a good sales month if Roger bought his K3 (s/n 46xx)

Congratulations Eric staff. I am just starting my assembly and will look

I know this is a little late for the contest, but if you're using the RTTY
decode within the K3, it defaults to 75 baud (100 WPM). You need to change
that to decode 60 WPM, which is the standard.

Jon,
I do not believe your condition has anything to do with digital modes,
but rather sounds like you have a power control problem - it should not
heat up that it is too hot to touch, and not as fast as you indicate.
I assume a K2/100. If so, please use an external wattmeter to determine

Elecraft does not recommend any fixatives on toroids in any of its kits,

Many fixatives will alter the inductance, and change other

Is it also possible that you're turning off your rig by shutting off the power

N1MM LOGGER GOES INTO RTTY MODE WHEN I select PSK D, understandably.
However, it means that my cw messages don't work.
Neither do the N1MM digital messages work because the K3 is expecting cw

So, do I have to hand key all of my transmissions???

Ian,
One set of washers is needed as a spacer - so just do it the easy way -
when you mount the standoffs onto whichever board they are mounted to
first, put the washers between the board and the standoff. When you put
the second board on the other end of the standoffs, put the lockwasher

Thanks for the quick reply. Fortunately, it appears that uncontrolled power

Your quick tests are sufficient to negate my initial suspicion.
I would say your next step is to re-do the KPA100 bias adjustment. If
you have the bias set too high, the PA transistors will heat more than
normal.

First, you cannot use PSK D for PSK31 with a computer unless you are
using the K3 Utility. All PSK31 software that I know of, other than the
K3 Utility, works by creating the PSK signal in a sound card and sending
that to the radio. In PSK D the radio does not accept audio input. It

John,
Rather than changing the SSB filters for digital modes, activate the
RTTY filter set in the secondary menu. That gives you a set of filters
(just like the SSB set but with the important difference that the SSBC
menu parameter is independent - always set to 1:1 for digital modes).
