I am a CW operator and I have 2.8kHz, 1kHz, 400Hz and 200Hz filters in
my K3. I think this is serious overkill (especially since I have another
similar set in the subreceiver).
The function of the crystal filters is to allow you to operate closer
than (roughly) the filter bandwidth to a signal

Hello John,
It's used for CW. I have a pair of them (main and sub rx) and find that CW
sounds more pleasing through this filter. I operate about 90% CW and I use
this filter most of the time, engaging narrower filters only when it
becomes really necessary.

I am selling my Factory built KPA500 amp Serial # 2217 and my factory built
KAT500 antenna tuner.
Both work great and are clean and a non smoking shack.
I am selling these together and do not wish to separate them.
I am selling them for $2400
Thanks

I received an email from a German ham telling me that he's observing the same
thing that I reported a couple of years ago. Specifically an audible "clicking"
sound in both my K3S and KPA500 that coincides with CW keying. See this thread:

What is this used for?

I have had this issue with my KX2 paddle and have two observations:
On my paddle, the screw that is meant to hold the standoff to the plastic
body will actually screw tightly into the plastic body *without* the
standoff. When this happens, additional torque applied with a screwdriver
has no effec
My K3S does show the voltage and current on its display. In receive it
nominally is 13.8 volts and 1.05 amps. For transmit, CW mode key
closed 100 watts output the current is 18.5 amps. Both of these values
concur with my power supply metering.
I've experienced no shut down while operating
If you have a dummy load, try running JT8 or JT65 into that at your usual
power.If problem does not reoccur, then likely RFI is the culprit.
If it does reoccur, then likely the K3 is having issues.

Buddy/Mike, further to my earlier email the current on receive is
actually 1.05A as measured on a digital multimeter and not 5A as
indicated on the PSU analogue meter.
Of course this doesn't solve the immediate problem.

It's useful to remember that a screw (or bolt) is a spring. When tightened
it stretches lengthwise. Like any spring, it offers the best "grip" when
subjected to the right range of pressure.

Mike, I am experiencing a similar thing. I had a session on FT8 a few

One thing I notice is that it appears to be drawing nearly 5 Amps on

As I learned from my previous manufacturing experience and knowledge, a
threaded fastener, a.k.a. screw, has a specific torque value which
should be applied to make it secure. The value depends on the screw
design, flat head, binder head, round head, undercut, pan head, etc.

Hi Tom,
First let me say that I am not trying to argue with you or correct you. I
just want to share what little bit of knowledge I have.
In my many years as a master mechanic in the heavy duty truck industry, I
can tell you without reservation that unless you use physical force

The point should be that a "drop of LocTite" isn't going to fix the
problem over time.
You should not have to modify a product immediately out of the box
because of a lousy
design.
Best regards,
