[Elecraft] Finding an RS-232 port on the K3

I have a K3, that has been upgraded with the addition of a KIO3B. I have a USB cable going from the K3 to my computer, and the RS-232 RJ45 jack has the Elecraft Y-type cable going from it to both connections on the P3. I have a Microbit AS-1289, web based antenna switch with an RS-232 output.

[Elecraft] Can not connect KIO3B USB with my MacMini

I am unable to connect the USB on my K3, modified with a KIO3B set of boards, to my MacMini, running OS10.9.5. I am not able to connect it to my MacbookPro running Sierra, 10.12.3, either. My Macs simply do not see the USB port. If I look at the “About This Mac” report on the Macs, I see that a

[Elecraft] USB devices disabled?

I’ve just had the KIO3B USB interface installed on my K3. When I plug it into my Mac Mini I get the following message: “USB DEVICES DISABLED - Unplug device using too much power to re-enable USB devices”. What does this mean? I am unable to connect my logging program, MacLoggerDX. THanks,

[Elecraft] K2, FD, and N1MM

I got the K2 out for Field Day and it performed great! I’d never used the K2 with a computer, so I hooked it up and set up N1MM for the contest. I was unable to get the function keys to operate and N1MM was a little unstable, sometimes locking up. I was able to log contacts, but couldn’t send

[Elecraft] P3 and Apple Display monitor

I've just installed an svga card in my P3 and I'm trying to get it to work with a 7 or 8 year old apple display monitor. It has a DVI male connector so I purchased a DVI to VGA adapter. But the setup doesn't seem to work. Any idea why? Any experience with this monitor and the P3 or is there a

[Elecraft] Latest battery arrangement for KX1

I love my KX1, but powering it with 6 AA Lithium cells puts out just 1.5-2.0 watts. I’d like a little more umph, since most of the time I use the KX1 in the field, so I also have a less than optimal antenna. I’d like to power it with 12V, but prefer not to use an external battery. Just gives

[Elecraft] Going 2014 with my K2

I love my five year old K2, and although I have a K3, I’d like to keep using the K2 for the field and digital. I’ve noticed that there have been discussions on the two items below on the reflector, but they are years old. Does this list’s collective brain trust have 2014 suggestions? 1. The

[Elecraft] Follow up on KX1 Field Ops

Last week, I asked for the group's help when I was in the field with a KX1 and an antenna that wouldn't tune. Here's my report. I trimmed the 66' wire that I have used as an End Fed Half Wave (with other rigs and tuners) to 41 feet, added a 15 foot counterpoise, and the rig tuned just fine. I

[Elecraft] Antenna and battery for KX1

I'm on vacation with my KX1 and my antenna isn't doing well. It is 65 feet of telephone hook up wire and a 15 foot counterpoise. Nicely up 20' in a tree but getting no tuning on 40 or 80 but tunes nicely on 30 and 20. I'm on the road so can't make too many adjustments. Any emergency fixes so I

[Elecraft] Modern battery for K2

Here is a nice little primer I have found on LiPO batteries. There are not the safer LiFePO4 batteries, however. http://www.rchelicopterfun.com/rc-lipo-batteries.html I am still wondering if anyone has a part number of a nice Li battery of any chemistry that fits into the K2 battery space.

[Elecraft] Modern K2 internal battery options

I have a K2 with the Elecraft internal battery. I think I'd like to replace the battery that's in there with one with more modern chemistry - has anyone found and installed a LiPO or similar cell that can fit in the space of the existing gel cell battery?

[Elecraft] Remote Rig questions

As of today, I am the lucky owner of two K3s and of a wonderful salt water QTH. I would like to remote the seaside K3 to my city QTH using the Remote Rig options available on the Elecraft website but have these two questions: 1. What do folks general use for disconnecting the remote antenna and
