[Elecraft] No Longer Deaf K3!!!

Thanks to Rick, N1RM, and his expertise in tracing circuits, my K3 is back in FB working order. We found that a switching diode on the bottom (fortunately) of the RF board had failed. (I think it was D25.). It was a low cost fix, and with Rick's surface mount skills a replacement was soon installed

[Elecraft] For Sale: Extreme Isolation EX-29 headphones

Sorry if this is a duplicate of a post that I tried to make a few days ago through nabble. It wasn't clear that I was able to post the message successfully that way. I learned about these headphones from earlier enthusiastic posts on the Elecraft reflector. The isolation and fidelity they deliv

[Elecraft] ICE 419 interface

I am in the process of connecting my K3 to a Model 419 ICE bandpass filter. Does anyone have a circuit or schematic of how they interfaced this filter with the outputs on the ACC port on the K3, or do I need a full-blown solution like the KRC2 band decoder? tnx es 73 - John, W4AU

[Elecraft] K3 #843 in CW SS

I operated in the CW SS this past weekend as an unassisted, SO2R station. I had my K3 as the main radio and was using it for running most of the time; I used my TenTec Orion as the S&P second radio. It gave me an excellent opportunity to compare the two rigs under fire. The biggest thing I no

Re: [Elecraft] K3: cw/vox/PTT ver 2.02 - bug?

Hi Don - I believe you are wrong here in stating that the delay of RF output after keying is fixed in the K3. Here is an excerpt of the notes from Wayne for the MCU 1.87, DSP 1.69 firmware update: ... "* VARIABLE AMP KEYING DELAY: Added CONFIG:TX DLY menu entry, which sets the time from KE

Thanks for the reminder to put K3 in the Subject: line I just installed the KPA module and attempted to do the High Power Gain Calibration procedure at 50 Watts. But all that happens is that I get 0 Watts indicated and a "ERR TXG" message. Any idea what is going on? Manual says to refer to

I just installed the KPA module and attempted to do the High Power Gain Calibration procedure at 50 Watts. But all that happens is that I get 0 Watts indicated and a "ERR TXG" message. Any idea what is going on? Manual says to refer to a mysterious "Service Manual". Everything works FB up to 1

Re: [Elecraft] K3 CW Rx Audio

I'm still waiting for my K3, but... I guess from the fact that you went through these gyrations means that one can't simply set the roofing filtering selection on "auto" and dial in a DSP width of 2700 Hz., e.g., or whatever with a K3 and have the 2700 Hz. SSB filter as the roofing filter; lik

[Elecraft] Microphone compatibility - Another Solution

What I have done with all my non-rig-specific microphones (2) and Heil headset/mics (3) is to install a simple stereo 1/4" jack on them. Then I have short pigtail adapters with the rig-correct mic plug on one end and a 1/4" stereo plug on the other. Makes it easy for going from one rig to anoth
