Hi,
thanks for the hints and information.
I will listen to the signal once with my K3. That seems to be the best way
to check the hint. But I will also have a look at the connector plugs and
power supply cables in my portable configuration.

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

I am usingga Raspberry Pi on my network to monitor and control the KPA1500
remotely. It also allows rotor control and AC power control turn turn various
equipment on & off. This is accessible from any web browser, local or remote

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 100k

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?Will
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.

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 Victor
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
conne
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 en
