I found it rather difficult to install replacement ear pads on the
CM-500. It seemed I did not have enough hands to hold all the parts
together when trying to align things and reinstall the 3 screws.

Occasionally I accidentally turn a key "press" into a "hold". A user defined
time constant for "hold" would be a nice option for all who want a shorter or
longer "hold" time.

Thanks to Harry, WE1X, for letting me know of a similar button problem he had.
It is most likely my problem is not caused by the components I suspected, but
rather by the failure of the switch inside the encoder for Speed/Mic.
I was thinking only of the rubber-covered buttons, which cannot resu
Seven of my front panel buttons do not function on K3 #757. I also used the
Switch Test to see that they give no scan codes. All other buttons work OK.
Looking at the the schematic for the "Front Panel - Switches" I see these seven
buttons are all connected to the SCANADC0 line into U3. I took o
I own K3 #757 and recently noticed some of the front panel buttons were not
working. They either did not work at all or gave strange results. I contacted
support, and they advised me to use the Config Menu SW Test to check all
buttons.
If you have not tried it, go to Config Menu, rotate VFO B
I would like to see this added to the Config Menu. I have low volume on
headphones, and a few doses of this command fixes it. I was going to contact
Elecraft support about it, but now I will wait for it to be added.

Shouldn't the above change be a mod mentioned on the "K3 Enhancements and

Thanks. You were correct about the problem. I have a short (3 ft) extender
cable connected to the KUSB cable. The junction between the two was slightly
loose. I tightened it and loaded OK.
I suspected the K3 because the MCU load always worked. It must be that the FPF
load exercised the d

Thanks. You are right -- I was expecting it on the LCD in the first few seconds
and not in the VFO B space.

I loaded the new K3 firmware (2.78/1.98) and the new K3 utility 1.2.1.6.
I click on the utility Configuration > Edit Power On Banner, type some
characters, and click Save.
When I power my K3 (#757) off and on, I do not see the Banner characters on the
K3 LCD. The LCD is blank for a couple of se

There was going to be a change to the KXV3 RX Ant I/O and Transverter card to

The reviewer (Solardx) gives the results of a test he ran on his K3. Surely
there are others out there with a K3 and the equipment necessary to repeat his
tests. The outcome of the tests will determine if Solardx's results are
typical.
I await the results while I wait for my K3 (wave 3).

I plan to use a K3 primarily for DXing. I want the second receiver
option so I can listen for clear spots and stations working the DX in
split operations.
For this usage, can you see any reasons to add additional filters to
the second receiver?
