[Elecraft] K3 IO1 Error Message
When I switched on my K3 on Saturday afternoon prior to using it in Field Day it came up with IO1 error message. I will contact technical support but wondered if anyone had experienced this before. Associated symptoms are: Doesn't recognise Sub Rx, ATU or 100w PA, ie max output is 12w. It was working perfectly in the week and I am thinking a connector may have worked lose in transit. Accessing the Field Day site involved a drive along bumpy farm tracks and a steep grassy incline which my 4x4 SUV coped with OK but apparently not the K3!!

Re: [Elecraft] K3 - SR2O
That's it!! I had forgotten about that menu setting. Works properly now. I can detect some low level crosstalk but I suspect less than the FT1kMP. Will check with some big sigs in WPX. Thanks for all the responses. Chris G3SJJ Guy Olinger K2AV wrote: Make sure you have that you don't have CONFIG: L--MIX--R set to something other than A b. Possibilities are A b, Ab b, A Ab, Ab Ab. Also make sure that you have CONFIG: SUB AF set to nor. Also it is possible to set L-MIX-R via programming over the serial line from a program, so it could have been left in this state from running a logger, etc. If those are correct, make sure you don't have a wiring error. The headphone channels with the above settings are completely separate on my K3. 73, Guy.

This works perfectly with the FT1kMP but so far I can't get it to work with the K3. Any suggestions?

[Elecraft] K3 Front Panel Problem
Having successfully installed the KRX3 I have a small problem on the front panel which I think is due to either a poor ground connection or a connector not fully mated. On power all display segments show, which I can't remember seeing before. Initially I could then see a lot of segments which cleared when I pressed on the FP. Now I am seeing less unwanted segments which clear when I press the left hand side of the FP, just to the rioght of the headphone jack. Before I take the FP off again has anyone an ideas where I should concentrate on? Obviously around the left hand side but anything in particular! The 2nd Rx sounds great.

[Elecraft] Help with download
Pressed the wrong button or something! Tx LED flashing but download has hung. I have switched off the PSU, switched on again and held the Power button down for 30 seconds which I think I had to do once before, but no success. Help please!

Re: [Elecraft] Help with download
Sorted. I had Disabled Router Queries on the mHam Router but it still didn't like it so I changed over a USB / Serial Interface and that worked. My bad. Sorry.

Just click Send All Firmware and the MCU should start to load. The MCU is in boot load status if the Red TX led is flashing. Restart the K3 Utility so that it finds the K3 again and again determines its baud rate (which will now be 38,400).

[Elecraft] KRX3 antenna routing
Whilst I am waiting for shipping notification of my KRX3, I have a question on routing. I have a specific contest application coming up where we will be using SR2O. The idea is for the 2nd op to be monitoring a band other than the Run band. We are only allowed one antenna and have designed it such that the KAT3 will handle all the impedance presented on the various bands. I had hoped that the K3/KAT3/KXV3/KR3X antenna routing would allow us to connect the 2nd rx directly to the antenna and not via the ATU. Studying the manual I can't see how that can be done. Can anyone confirm this? If not, I can make up a small relay box which takes a feed off the antenna input to Ant 1 socket and feeds it to Aux RF on receive and grounds Aux RF on transmit and I can switch it via the PA PTT switch on my mHam Keyer. An internal switching solution would be more sophisticated! Chris G3SJJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KRX3 antenna routing
Hmm, that would be nice but I suspect we will mostly be running on a lower band and searching for QSOs on a higher band. Eg, running 20m, searching 10/15, running 40 searching 20, running 80 searching 40/20. If we had a decent opening on 15/10 it might work. Thanks for the thought Al.

[Elecraft] K3 ATU
Does anyone have any figures on efficiency of KAT3 for load impedances of 20 and 200 ohms? (reactance not known at this stage.)
