Re: [Elecraft] Contemplating Purchase of K3

Gil, If you're a cw operator, I make heavy use of the 400 Hz filter. Not too narrow (usually), and not too wide. 73, Mike ab3ap On 03/07/2015 11:42 AM, Richard Gillingham wrote: I’m thinking about purchasing the K3-100 kit. [...] With this bare bones K3, is there anything else that you

Add in 350 Hz to that and you have a dial tone. (Really!) 73, Mike ab3ap On 02/28/2015 04:14 PM, Joe Subich, W4TV wrote: 440 Hz is A above middle-C. Middle C is 261.6 Hz. 73, ... Joe, W4TV On 2015-02-28 4:05 PM, Don Hall wrote: Years ago I went to 440 (I believe this is middle C)

[Elecraft] K3 DSP rev D board S/N's

Regarding the recent thread about the K3 DSP board, according to http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm it says that beginning serial number 3626 +/- 10, K3s shipped rev D of the DSP board. Hope the info is useful to some. 73, Mike ab3ap

Re: [Elecraft] Software perfection

Straight out of college I was one of 100+ design engineers on the Mode-S FAA air traffic control system - multiprocessor, fault-tolerant system, etc. The design docs (let alone software) filled volumes. Much as I hope there were zero bugs in the complex system, it was after all designed by

[Elecraft] Scope, anyone?

Hey all, I have an analog scope, excellent in its day: http://udel.edu/~mm/tektronix/ If interested, please contact me. It's yours if you can pick it up. (Sorry for poor phone pics. Camera pics can be provided.) I also was given an old Heathkit scope, ca. '62, from the estate of an SK.

Re: [Elecraft] Slide rules

I have a couple nice bamboo Hemmi slide rules, one even devoted to electronics calculations, but my most cherished is a cheap 12 log-log plastic Sterling. My late mom bought it for me from a drug store when I was in 8th grade. It took weeks of begging and groveling till she gave me the $6

Re: [Elecraft] External controls for the K3?

Hisashi, Not as convenient as physically remoting the buttons, but I wrote a small C program that sends commands to the K3. I then made some short aliases using that program name. If I type the letter a the K3 sends my call, AB3AP. If I type 9 it sends R 5nn TU (7 sends R 57n TU, etc.).

Re: [Elecraft] Current version of Windows K3 Utility ?

I did the same a few days ago using an out of date linux K3 Utility. What a bad feeling. :-o I wonder if the firmware can be distributed with a file (or somehow with info) indicating the minimum K3 Utility version number required. That way an out of date K3 Utility can complain about its aged
