Re: [Elecraft] CM-500

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. This article "Replacement Ear Pads for the CM500 Headset" by - Mike N4CF in the May 2020

Re: [Elecraft] K3 test mode

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. 73, Paul K5ESW A user defined longer time constant for PRESS functions would be a great help.

Re: [Elecraft] K3 button problem question

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

[Elecraft] K3 button problem question

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

[Elecraft] K3 Check Your Buttons

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

Re: [Elecraft] Question on KRX3 Installation

In errata C-7 dated March 15, 2009, page 1, there are instructions to cut two traces in the area to the right of D40 on the RF board. Shouldn't the above change be a mod mentioned on the K3 Enhancements and Application Notes info maintained on the Elecraft Website? I installed the KRX3

Re: [Elecraft] K3 Load fails

Dick, 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
