It does appear to be a synthesizer board. The LED lights on only one of the boards. I am going to swap them. I think that will tell us if it that particular board, or something in the circuitry that b

I was on the air for a short while yesterday, and my entire lineup of Elecraft gear (K3/P3/KPA500/KAT500) was working perfectly. I shut down after a few transmissions to work on a small project for a

Larry - That is pretty clever. Did you make that? Or did you find such a device already to go? By the way, I have recently begun playing with RTTY, and VP9I was my first VP9 on that mode. 73 de Dave -

Jim - I would have a hard time spending $120 for a single speaker that, according to the QST article, does not sound much better than the speaker built into my K3. For just 1/3 that price, I have a pa

Tony - I put in one new board in my K3, and a pair of them in the K3 of W9FAM. I almost never go as fast as 38 wpm, but W9FAM almost never goes that slow, and HE IS THRILLED at being about to send CLE

Todd - Many thanks for your helpful post. I never paid attention to ANY other logging programs, after I started using DXLabs several years ago. I do not anticipate changing, but I now think I have a b

Yes, he does. I believe this thread started when he said he was about to order the SVGA card. Dave - K9FN

Wayne - I shared this in a private email to Phil, because I could not imagine anyone else might be interested... but as a 15 year old Novice in 1957, while living in a Western Suburb of Chicago, IL, I

This is very exciting to contemplate. I maintain the station of a 93 year old friend who generally operates at 42 wpm and up. He got a K3, largely on my recommendation, and now uses it far more than h

Martin - My KPA500 is SN 1530, very near yours. I had the same problem recently, and I returned the LPF/PA module to Elecraft. They upgraded the T/R switching circuitry. A transistor had failed, and t

Ray - Welcome back to the bands. And, welcome to the Elecraft family. I think you made a fantastic choice of rig. I run my K3/100 from an Astron RS-35M supply, and am fully satisfied with it. A lot of

Larry - Congrats on your new acquisition. The only things I would want to add to that would be the sub-receiver (I am still saving for one here), the P3, the KPA500 & KAT500, all of which I am fortuna

I recently replaced my shack computer with a Windows 8.1 machine. All was working FB until I wanted to upload some new firmware to my K3. This new machine does not have a serial port. Rig control was

Brian - I have not removed any other cables... I had not thought of that. Transmitting a single dit (or more) has no effect. Dave - K9FN

I searched for info on this, but had no success. I am running a K3 with KPA500 and on 80 meters I notice that when I switch the amp from STBY to OPER, my receive level drops about 1 S unit. This may h

Mike - Thanks. I'll check on that when I next talk to him. Dave - K9FN "Mike Flowers mike.flowers@... [Elecraft_K3]" <Elecraft_K3@...> wrote: Hi Dave, Found this in Fred Cady’s book.

Mike - Thanks for the response... but on mine it switches on CW also... so I remain unsure of how to help my friend. Dave - K9FN

On my K3, when I press the button to switch between SHIFT and LO CUT, or the button to switch between HI CUT and WIDTH, the radio does exactly what I expect it to do, and the appropriate LEDs light to

Like paddles, footswitches can be VERY personal. Fortunately, there are a number from which to choose. It appears that you have gotten some very nice suggestions... I'll throw in one more. http://line

Keith - Thanks for the respons. I am also subscribed to the Elecraft reflector. I guess I just missed all the previous posts. Dave - K9FN
