[Elecraft] [KX3] Legs

I'm in the process of upgrading our club's K3, new synth, DSP and a stack of small mods. I've come up against an issue that's causing me some confusion. The mod for the KPAIO3 consist of a small electrolytic capacitor soldered to two pins on the KPAIO3 module. I have two versions of

Yes Ingo, you can use two washers on each leg's thumb-screw with the leg sandwiched between the washers. At least this works for me. 73 Ken - K0PP On May 28, 2017 03:41, "Ingo Meyer, DK3RED" wrote: > Hello Elecrafters, > > > I have a little mechanical nuisance with the legs

I like WSJT-X but I use JTDX as much or more. It adds some interesting features to the decoding. WSJT-X interface is a little more polished but JTDX isn't bad. Read about different versions and try them out before discounting them because someone says so. 73, Kev K4VD On Sun, May 28, 2017 at

[Elecraft] KPA500 not working

Hi, My KPA500 started acting up and now does not amplify at all, and the input SWR seems to bounce around. I did hear what sounded like an arc (fairly loud bang, though it was the KAT500, not the KPA500) The KAT500 is still working normal, but the KPA500 is bad, even into a dummy

Hi Ron. Thanks for the confirmation. I figured out that Rev A was a mistake, after looking at the fan connector and fan supply orientation. Had Rev A been used it wouldn't have been a disaster, but the mod would have had no effect, as it connected both ends of the capacitor to the positive

Re: [Elecraft] P3 question

To expand just a bit, when commanding a QSY from the N1MM+ entry window, the P3 seems to put that frequency in the center of the screen in fixed-tune mode placing the edges +/- 10 KHz from it. If I QSY to 14050or 14070, which are the center of a 20 KHz boundary, the right and left edges of the

Re: [Elecraft] [KX3] Legs

You should tighten the screws after extending the legs. Get them tight. Never fold the legs without loosening the thumb screws first! One leg will tighten more if don't loosen the screws first. This problem could have been eliminated if they had use a left hand thread on one of the legs.

[Elecraft] CP1 vs other directional coupler

I'd like to get a directional coupler to, among other things, monitor my transmit signal on a scope. The Elecraft CP1 kit is priced well, but I'd want it in a metal box with panel mount connectors, SO-239 for the main RF path. I'd also rather use 50 ohm terminators rather than switches, so

[Elecraft] KX2/3 Amplifiers

Greetings, I'm looking for a little practical advice about linear amplification for the KX2/3 (I have both). Hardrock-50 or KXPA100. Essentially, it would be used mobile, although taking it out the car and using it portable is possible. So any information from users of these two amps will

I looked into that very question a few months ago (February)… My comments: 1. I don’t think Hardrock-50 has an auto-tuner so in pricing comparison, compare with a separate vendors auto-tuner (as good as Elecraft’s) if you are assuming buying the KXPA100 with auto tuner. 2. Hardrock-50 is

Phil, The Hardrock 50 has an atu - I don't know if the toroids are pre-wound or not - if not, that's an issue for me. Actually, I'm kind of in the reverse situation - I want to keep my KX2/3, but get rid of my FT-450D - which is a nice radio, but it's bigger than I can use mobile. All

[Elecraft] KX3 alc/cmp and swr/rf display

When I priced them, the Hardrock was just about half the cost for half the power. I got the KXPA100. The KXPA100 kit is assembly, no soldering. One of the design goals was for installation as a remote PA for mobile use. Install the KXPA next to the antenna and keep the KX3 by you. wunder

It would be pretty easy to modify the CP-1 to use SO239 connectors and mount it in a box. I would do it while building the board - drill four holes in the corners for mounting, mount the SO-239s on the box and wire them to the board. But, I would also keep the BNC connectors for the test
