I occasionally hear my windows system play the USB disconnect/connect sound when nothing has been plugged in or removed. Using USBDeview, I found it seems the K3s Audio Codec disconnecting and

I do not know if this works with all radio / KPA1500 combinations however with my K3S/KP1500 I do the following.Hopefully it i something as simple as this. I do not use the ATU in the K3S. Tune the

What is the SWR with the amp on but in the SSB part of the band? Does the SWR jump there too, or does it provide a good match? I don't know if the TH6 uses traps but it could be the amp heating up

The first thing that occurs to me is that something is going wrong with the antennas or feedlines at high power. Does the SWR go high in the OPER position at 100 W, or only at higher

A friend of mine has a KPA1500 that's having strange issues with the ATU. The SWR on his Hygain TH6 tri-bander is kind of high in the CW band because it's tuned for SSB. When he goes down to CW on 20

Excellent Thanks The remote on/off of power at 120vac level is next. 73 W5AJ

Thank you Klaas. Sherm w8hi

That was exactly the fix, Mike...per N1MM support...logger doesn't know "length" of message...so add 5 sec to recorded length of message...works fine now... 73, Neil AE1P

I had a similar issue when wishing to power up the K3 at the remote station every time the 12V power supply was switched on. My solution was an 8 pin PIC, see

Hi Guys. Not had these issue with my line up, however had issues with flashing software. (K3 Bricked) As Engineer having updated software "all my life" and having experience over here with the K3 -

Friend of mine in Eastern Oregon Mountains was experiencing what seemed similar. Tried all sorts of normal trouble-shooting steps with no resolution. He was running WSJTx and monitoring WSPR. When

Thanks Joe. The thought that the PTT response is a red herring had occurred to me. That's one reason why I am not 100% sure whether its the K3s or the P3. You are correct that I do not have the TXMON

Mine is different, flashing in cold weather, nothing on K3 changes it. So thinking electolytics P3

PTT is a red herring ... The display update is suspended in transmit unless you have the TXMON option installed (which does not appear to be the case). 73, ... Joe, W4TV

In my case bothe the P3 & external monitor flicker until it settles down and works properly. Lou KE1F Sent from my Galaxy Tab® A

Hi Alan, No, I have not tried that. Maybe this evening after work I'll give that a try. Thanks for the suggestion. I'm pretty sure the issue is in the K3s, probably on the KIO3B, but I am not quite

Hi Chuck, Have you tried doing a Parameter Initialization? (Described in the Troubleshooting section of the P3 manual.) Alan N1AL

Here is a link to a video I shot showing the issue. Hopefully it is accessible from here. https://photos.app.goo.gl/32VjRyny1gJmfx1Y8 Chuck Wpbik

I’m not able to get anything on my monitor from the P3. When I plug in either the Elcraft or replacement 15 pin cable, between the ACC on the K3 and the RS232 port on the P3, The K3 freezes while
