Hi, My KPA500 S/No 1278 decided it had enough of CQWW SSB this weekend and popped the tops off the PA transistors VRF2933 . First time ever I had used the amp at the UK full legal limit of 400W. Amp

Henk, Thank you for the troubleshooting ideas. I have connected the IF output to a second receiver and the noise is still present. I am currently looking into how to look at the

Hi Tim. I've just sent you a pm with a .zip attachment. If you haven't rxed it by the time you read this, please let me know. For the benefit of others reading this, there is a K3 Band Limits Editor

Been playing with my new to me K3, was going to call in on a 5MHz CW net but the radio is blocked for the U.K. 5MHz LF allocation. Is there an easy fix for this or do I need to contact Elecraft for a

Hi Paul, That should be feasible. The only thing the Remoterig boxes do is conversion of signals, so they can be transported over the internet. Without them you can connect all ports directly. The

Hi Rick, This could be anything, but sounds like an almost broken capacitor. You need to find out where in the receiver the noise is generated. A good place to start is the IF output

I have been operating from within my Jeep and primarily from the passenger seat. I spent a lot of effort perfecting a KX3/PX3 system where two of these are mounted on my dash.

I have a K3 that has worked great for many years but now has a noise source somewhere in the receiver. The radio still hears stations but there is a new source of static bursts on all bands. It sounds

Thanks Alan, yes, I did that latterly to save time! I will try to do more work on the rig later and report back if I find anything wrong John

John. I'm not sure if this has been asked before, I may have missed it. Are you sure that you don't have the power set to "Per band"? I'm not sure if that would affect the readings you're getting, but

Thanks Mike, Mel, Ray and David for suggestions. Volts over 13 in all cases. Tried 13.5 but this not the problem. ATU bypassed for tests. LPA output OK at 10w all bands. Only removed ATU so far but

John Have you redone the 5 and 50 watt calibration on each band? See manual. 73 David G3YYD

Hi John…. Run a Power output test on 160- 10 meters with the Antenna Tuner Shut off / Disabled. From previous post, Clean ALL interconnects in the RF Stages of the K3, Boards… K3LPA and KPA3.

John I am not sure if you are aware that under 12W you are using a different board than when you run over 13 W Mel NE9A

Hi John, What input VDC does the K3 report during TX over 50W? - 73 and good DX de Mike, K6MKF, NCDXC Secretary

I would appreciate some help fixing an unusual power anomoly on the K3 (2481) I am using. It gives the normal 100w output into a dummy load on HF bands but only 70watts maximum on 1.8 and 3.5MHz, and

Hi Joe; KDVR3 FW 2.05 was released in Aug 2019 (your rig was prior). It is current as of today, Oct 2020 (for new type boards only. 1.04 or earlier is good for earlier boards). Please coordinate with

Hi Keith My K3S was delivered as brand new from Elecraft in winder 2018/2019. Have you forgotten to upgrade the DVK inside before shipping? I know that there are some K3 and K3S in Denmark and

Thanks to all who inquired about the KPOD I offered for sale. It has been sold. 73 de Jim - KE8G ---------- Forwarded message --------- From: KE8G <ke8g.jim@...> Date: Mon, Oct 19, 2020 at 2:24

Thanks Keith, I have already been contacted by others regarding my question to you. I think there may be a bunch of those over here. I’m sure Elecraft records must show how many are in the
