[Elecraft] Charging IMEDION2400 mAh batteries?

I have these MEDION2400 mAh batteries that I am using in my KX3; I have 2 set of them so I can be charging one set while operating with the other. My question is, using my Powerex programmable charger, what settings should I use for current and time? Thanks in advance & 72 de Dave, W5SV

[Elecraft] [K3] FW 5.5 issue??

I installed K3 FW 5.50 to use my K-Pod, which I like very much. I have a couple of weird problems using DXLab now that I can't explain and wonder if the new FW might be related. In DXLab, when I click on RTTY DX spot in SpotCollector the K3 changes the frequency in the K3 but it's 850 Hz

Per-Tore, The band data outputs should follow the band set on VFO A. That should not change with RX ANT in or out. If you have VFO IND set to ON, the band outputs should still reflect the band for VFO A. The other thing that affects the band data output is the menu CONFIG:KIO3 - if set

I think 42 might be a valid answer, depending on the question. Forty-one is certainly a good answer! There are a couple pages that try to address the question of what long wire lengths are the easiest to tune, i.e. present a low SWR to the matching unit. The first is at

Re: [Elecraft] KPA 500 Hum

You may not have the transformer properly tightened down. Recheck it. Also, 58V is not that bad, but you might want to recheck that you are using the proper tap from the transformer. You just might want to go up a notch to get a higher voltage. Essentially you want the tap that provides the

Re: [Elecraft] how to optimize end-fed?

Maybe I'm missing something, but you have a selection of taps, the highest is 16:1. If the wire is exactly 1/2 wave, then the impedance is going to be very high, and the 16:1 tap will come closest to matching a high impedance load. If the wire is some multiple of 1/4 wave but not a an even
