Re: [Elecraft] Keyboards revisited

Look at the Logitech G13 game board and see if it might suit your needs. It has 25 programmable keys, which should be plenty of CW macros. - - 73 de N5ILN Alan On Wed, Apr 30, 2014 at 11:51 AM, John Lawrence via Elecraft < elecraft@mailman.qth.net> wrote: > Function keys continue to be a big bi

Re: [Elecraft] Transporting Lithium Batteries

I used to work in freight transportation. Here are the notes I took last year, when the lithium-battery regs were explained to me: The metallic lithium content limit for transport by air in carry-on is 8 grams equivalent for LiPO packs. The equivalent is calculated as 0.3 x the capacity of the pac

Re: [Elecraft] [K3] Hearing aids, meet K3

As I recall from my broadcasting classes years ago, human speech has a "typical" bandwidth of just 3KHz. "Normal" human hearing, IIRC, picks up frequencies from 20Hz to 20KHz. If someone has a copy of Schrader's "Electronic Communications" ready to hand, the specifics should be in there somewhere.

Re: [Elecraft] Any way to block the spammers who discovered Nabble recently?

Thunderbird is, indeed, actively supported. I've used it as an email client for several years. Combined with Gmail, it's remarkably effective at keeping the spam off my screen. We now return to our regularly-scheduled discussion, already in progress... -- 73 de N5ILN Alan NAQCC # 6139 ARES Assis

[Elecraft] (OT} Spam influx

With the spate of spam messages, I'd like to humbly suggest that the list owner switch the list to Moderated status for a time...at least, long enough for the spammers to get tired of their messages not getting out. -- 73 de N5ILN Alan NAQCC # 6139 ARRL EmComm Field Instructor ARES Assistant Dist

Re: [Elecraft] [KX1,K1,KX3] QRP Portable Antenna

I'm not an antenna designer or RF engineer; I'm just a reasonably average amateur. But I got surprisingly good results with an off-center-fed antenna made from 24-ga solid-conductor speaker wire. I connected the conductors to a BNC-to-binder-post adapter right to the antenna output from my KX1 (wit

Re: [Elecraft] K2 diminishing power on 15 to 10 meters

Not having the schematics in front of me and not being familiar with the unit...PCB traces don't usually burn on their own. Did Q4 check as good? Might be worth some desoldering to put an ohmmeter on it. 73 de N5ILN Sent from my iPhone On Jul 21, 2012, at 7:40 PM, aj4tf wrote: > Interesting,

[Elecraft] KXAT1 intermittent relay drop

I inherited a KX1 about three weeks ago, and until this afternoon it had been performing flawlessly on a random-wire antenna and counterpoise. Today, I was trying to call CQ on 20m, and after running a tuning cycle and seeing a 1.2:1 match, I started calling CQ as usual. In the middle of sending a

[Elecraft] Unsolicited testimonial for KX-1

Yesterday, I did something I've never done before. I worked a contest -- the IARU HF Championships -- using only CW. And I did it with an inherited KX-1 (I'm still trying to find where the original builder put the serial number sticker) and a random-wire antenna tossed into a small tree outside my

Re: [Elecraft] Firmware upgrades using Ubuntu 12.04

As I just pointed out on a local discussion that was in the middle of a Windows vs. Mac debate: Linux is for technicians. Windows is for management and accountants. Macs are for artists. All three can do some serious number-crunching. But Linux, especially in the command-line mode, is best describ
