[Elecraft] KXPA100 amp and ATTN switch
I just connected my new KXPA100 to my KX3 via a home-brew KX3-KXPA100 Adapter Cable. Everything works just fine if I have the 3dB attenuator switch set to IN. I fI set it to OUT/AUTO as described in the manual I end up overdriving the amp, meaning the power out is much higher than set on the KX3. All the other functions work just fine. Anyone have any ideas?

Re: [Elecraft] PX3: Possible problem with display
David Thanks for all the info. Wayne seems to have explained it fairly well. I think there were a few contributing factors in my setup. I have a new and quite a bit quieter antenna, thus less noise to cover up the small spikes. I never had the NB on but I had the PRE AMP off on 20M. Most of the issues are now masked with more noise and higher gains. I redid the OSN settings one more time and things seem to look better. The whole issue started with 15M which I think needed the OSN to be trimmed up a bit. Now all looks to be good. It was a combination of me looking too close and one band needing a touchup OSN calibration.

Re: [Elecraft] PX3: Possible problem with display
I am pretty sure they are internally generated, plus they move with the cursor. They are mirrored above and below the cursor. I ran everything on batteries and took it for a walk outside. No change in signals. The S1-2 spikes aren't bad as band noise will mostly cover them, it is the S4 spikes that are concerning. No amount of OSN makes any difference as far as I can tell. No change while fiddling, moving or twisting cables either.

Re: [Elecraft] PX3: Possible problem with display
Don Thanks for the suggestion but that does not fix/improve the situation. Looking at it further I also have spikes at roughly 23, 30 and 52Khz above and below my cursor. The 52 Khz signal is at S4 the other two are about S2. I can turn on the PX3 and look at the display with no antenna connected and see these spikes on every band. If I disconnect the cables to the KX3 the signals are still there but go down to S1 in strength. I have even tried running both on separate battery supplies but the problem is the same. The spikes are there even if I disconnect the I/Q cable but the spikes are very small, as soon as the I/Q cable is plugged in the spikes increase.

[Elecraft] K3: CWT and Volume wish list
I have a couple of minor things that I would like to see included if at all possible. The first is the CWT feature. I wish it would stay on when I swap bands or go to SSB then back to CW. Being king of tone deaf this is a great feature for me but it always toggles off. The second item has to do with my hearing also. Being an old fart, my left ear is not as good as my right. It would be nice to be able to balance the left and right channel to account for this. I am sure the AFX feature would work better. I know I can add an outboard control to do this but I like a clean setup without a bunch of extr wires and controls hanging around. I also want to say how much I like running PSK with the paddles, I've had a lot of fun with that feature. Also getting ready to put in the KRX3 module, this ought to really add to the radio. Thanks for a great product.

[Elecraft] HI CUR question
I sometimes get a HI CUR warning on my new K2. I have the high current set at 2.5 amps. My power supply is steady but on 40 meters when the SWR is slightly high but below 2:1, I get a HI CUR when running 10 watts out. Into a good 50 ohm dummy load I get 2.02 amps on 40 meters. I've double checked my output filter tuning and all is good. Is this something to be concerned about or is this in the normal range of xmit current at 10 watts?
