If you are getting an ERR PTT when you power on, then either the key
(Paddle) is closed or the PTT in the microphone is stuck in the active
position.
Remove the hand key, paddles, any PTT switch or footswitch and
microphone to see if the Error goes away.
If things are then OK, plug each one

Perhaps KV5J can come up with an amplifier monitor for the KPA-1500, too? Hope
so!

Phil,
The only problem with a simple Y connection is that the mic will be
'live' when using the DTMF pad.
If you need an attenuator, try a 100k in series with the cable and a 10k
from the line to ground. Those values are high enough not to interfere
with the mic. Adjust the value of the

I need to interface a DTMF pad to the mic input for special-purpose
signaling but I have not yet found a desk mic that has DTMF capability
built-in. Has anyone had any experience doing that? If an external pad
is required (I have one floating around here somewhere), how can it be
done?
Grant,
thanks! I did not know that, or had already forgotten this twelve years
after assembling the rig. I was also thinking that a backup and restore
of the settings would be sufficient. I am going to replace it soon.

I have a new problem crop up seemingly with the PTT on my MH2 / K3
setup; sometimes it works fine, but might drop out in the middle of a
transmission, with the K3 display momentarily displaying (it flashes by
pretty fast) something about PTT Problem...
I am trying to figure out if there is

Don’t get too excited. I’m told it only keeps the clock running. All settings
are in non-volatile memory.

Ha ha, yep. I worked DXCC as a Novice in 1957-58, all on 15 CW. It's true
that signals were popping in

Except that noise levels have escalated by 20 dB since that era.

The battery supports the real time clock only. You won’t lose any other
settings if you replace it.

Hi,
has anyone already changed the CR2032 backup battery in a K3? Under the
carton cover the battery has started to oxydize but the Voltage is still
3.06 Volts after twelve years. I guess an external 3 Volts source should
be applied to save all settings during the replacement.

Thanks to all who had suggestions.
Windows had made an update and changed audio settings.
Problem solved.

A search through the archives will find that addressed many times.

I don't have any experience with chirps, but I can add this bit.
If you can hear the change, then the change can be seen on an FFT. At least
that would give a sense of whether the shift is up or down, if it is difficult
to tell by listening. An FFT could also be applied to the RF, but, as
Generally a chirp would be due to an unstable power supply, resistance in
the fuse holder, etc.. It can also be cause by poor decoupling/loading of
the oscillator circuit, but in the case of a well-designed circuit like the
K2, this would normally only arise with misplaced components or poor
A chirp can't be seen visually on an oscilloscope (well, maybe on a
panadpter or spectrum analyzer if it is a very big one).
A chirp is a change in frequency of the transmitted signal. It is not
the same as a click, which is a wide signal caused by too-short rise and
fall times of the keyed
Hi,
since someone told me that there is a small "chirp" in my K2-CW signal, I
would like to check the signal visually.
How can I display the CW Key envelope as shown in the document "Elecraft K2

An oscilloscope "Tektronix 2465A" is at my disposal, but
Dear Friends,
Nor are SSB, RTTY and PSK the same as CW but they all serve a purpose.
Any technology which allows one to work weaker signals with lower power is
going to make DXCC easier.Even using CW it is infinitely easier to work
