Re: Factory service still available?

I had that intermittent TX problem with my K3. I had to power cycle the K3 to reset it to again TX. After a few email exchanges with Elecraft I think these recommended settings fixed it: TX INH

Re: Factory service still available? [WSJT-X bug?]

I think it is the computer operating system which likes to go back to its factory set default. The Flex Radio SmartSDR has the same problem and the developers seemed, at least in Windows, to concede

Re: Factory service still available?

Thank you Bob for the ideas. I just put the K3s into Tune and sure enough I was seeing the usual 20 watts (what I usually use with the amplifier) out on my station monitor so there's not an RF problem

Re: 100 watt PA issue

I honestly don’t think I ran the K3 at more than 7 watts, to drive the AMP there is much info on this in the archives about the 12 watt usage, I just don’t remember. Unless 7 watts data usage is a

Re: 100 watt PA issue

Jeff, The “Achilles heel “ in the K3 power stages is the 12 watt amplifier which is only conduction cooled. In normal use on SSB/ CW modes it seem to be fine all day at 12 watts out ( 8 watts out

Re: Factory service still available?

John, This could very likely be an RFI problem, with RF getting into the PTT circuit. I had a similar problem. Try reducing the rf output to A very low value say 1 watt, and see if everything runs

K3s CODEC access

I have lost Audio CODEC audio option in WSJT-X. It was working but no longer in WSJT?Setting/ audio dropdown. How do I restore CODEC for WSJT-X? 73, Jim K7EG

Re: 100 watt PA issue

L23 is in the 20/30m low pass filter. The only thing I can imagine could cause it to fail is a very badly mismatched load with just the wrong impedance. It's also possible, of course,

Re: 100 watt PA issue

According to the schematic I have, L23 is part of the 20/30 meter output LPF. If it's been overheated I suspect a mismatched load was encountered at some time. Does your problem occur only 30 and/or

Re: 100 watt PA issue

Well I was asking anyone if they had a clue about L23, I guess not :-) I will call Elecraft tomorrow… 73 Jeff kb2m

Re: Factory service still available? [WSJT-X bug?]

Precisely. Same issue here. The fact that the TX audio "comes back" when WSJT-X is restarted seems to strongly suggest the issue is with WSJT-X. I have the same issue with no transmit audio. This

Re: 100 watt PA issue

I remember all of this now. Actually I was running about 7 watts to drive the AMP after I had the PA failure at 100 watts, there were no issues at 7 watts. I was trying to make the point that I was

Re: 100 watt PA issue

Running 12 watts on data modes is bad. The low power PA won't withstand that. -de John NI0K Jeffrey griffin wrote on 5/3/2020 12:35 PM:

100 watt PA issue

Last summer I was running more data modes (FT8) when I started having an issue with the 100 watt PA failing with a ERR 12V message. I then did the KP3A power connector replacement. This worked fine
