Re: [Elecraft] K4: savable profiles?

[Kidder, George]

The commands in the Programmer's Reference can all be executed from a 
macro in FLdigi, and I suspect from many other add-on programs as well.  
This takes care of most of my needs for the K3, and I would expect the 
K4 would be similar.

Re: [Elecraft] VX commands don't work

[Kidder, George]

Well, now, I am both confused and eating crow!  Now it is working as 
expected.  I have no idea what I was doing wrong before.  Both the VOX 
function and the indicator are now going on with VX1;.

Talk of a tempest in a teapot!

GE Wes - Is your success on a K3 or K3s?  Just installed latest firmware 
(5.67) and there is still no SET response to "VX1", although "VX" does 
GET the state.  Just like Don said, but this is not what is in the manual.

Re: [Elecraft] VX commands don't work

[Kidder, George]

Hi Dick,

Problem there is that I would have to "press" or "not press" depending 
on current state of VOX, and the macro generator (FLDIGI) does not have 
that sort of programming ability - at least I don't think so.

But a good thought.

Re: [Elecraft] VX commands don't work

[Kidder, George]

Thanks for the prompt reply, Don.

Humm. My copy of the Programmer's Reference, (Rev.G1, March 16, 2017) 
says on p28
"VX (VOx State; GET/SET on K3, GET only on KX2 and KX3)"

Guess I have encountered a "feature".  No problem - if it's not, it's not.

Re: [Elecraft] VX commands don't work

[Kidder, George]

GE all,

I recently tried to incorporate the VX command into some macros for my 
older K3.  With the K3 utility connected directly to Com1, the VXn 
command has no effect on the VOX state, although other commands work as 
expected.  I run the VOX on AUTO OFF (CW WT tap 5) to avoid startup 
problems, but returning to NOR has no effect.  Is this a known bug or a 
single-unit flaw.  Any others have this experience?

I can certainly live without this feature - I have for nearly a decade, 
but it would be nice to have it in some macros.

Re: [Elecraft] QRP FD KX2 Batteries & FT8 Report

[Kidder, George]

This would seem to be "from the horse's mouth"
Sorry about the formatting as copied from the PDF file - George, W3HBM

From: http://www.arrl.org/files/file/Field-Day/2019/2019-FD-FAQ-RevA.pdf

Q.  We don’t have an area club, but we do have a small group of area hams
  (generally two or three of us get together for
operating events).  I have a l
arge
-deep
  property, and w
e will be setting up in my back yard.
What Class would we be
?
Class A, Class B or ?
A. Convenient access across one’s backyard to their home station 
facilities is not in keeping with the spirit of Class A or C
lass B
portable operations. Such convenient backyard operations on property of 
home stations remain either Class D (commercial power)
or Class E (emergency power), even if home antenna structures are not 
used. If the station will be a ‘good hike’ away from a hom
e
station (
eg, at the rear of a several acre lot, or perhaps operating from a 
farmers field down the road) -
  clearly away from home
conveniences (away from home utilities, or home restrooms/bedrooms, or 
even eating
  facilities/refrigerator/kitchen)
- then Class A
(3 or more pers
ons portable) or Class B (1 or 2 person portable) is appropriate.

Re: [Elecraft] Terminal resistance

[Kidder, George]

Interesting data, Don.  I wonder if there is any information about 
resistance variations between soldered and crimped terminals.  One might 
think that, with stranded wire, even a good crimp connection might not 
solidly involve all of the strands, and might additionally deteriorate 
with time since oxygen could get between the strands.  A good solder job 
should wet the wire through and (additionally) exclude oxygen.  This 
wouldn't be easy to measure, for sure, but these engineers are cleaver 
people!

Re: [Elecraft] Cinch Jones Connectors

[Kidder, George]

If I remember rightly (and it's been a LONG time) there was an outer 
shell pair made for at least some sizes which locked together external 
to the shell.  Even without the lock, the multi-pin models (especially 
in the larger sizes) took some umph to get them apart.

Ditto.  Made mine from an old microswitch from junk box, some pine

[Elecraft] Suggested enhancements for K3

[Kidder, George]

Two suggestions which can probably be added in firmware for K3 and K3s:

1)  Allow different audio levels for speaker and phones, such as an 
attenuation applicable to either.

2)  Allow (but not require) the monitor level to be controlled along 
with the receiver levels.

If either is already available for the K3, someone please let me know!

Re: [Elecraft] K4? Voice commands

[Kidder, George]

I have a distorted vision of the following:

Your K4 is on SSB, tuned to the net you are checked into.  Your VOX is 
on - you forgot.

Your K4 (VOX already activated)  "Ellie, turn on the VOX"

At 13 other K4 stations, the speaker repeats "Ellie, turn on the VOX", 
and these 13 rigs respond by doing so.

13 operators, not wanting the VOX on, say "Ellie, turn off the VOX", 
which, since the VOX is now on, is transmitted (nearly simultaneously) 
on the net frequency.

(etc. - complete or alter events to suit your own distorted imagination!)

It is enough to make a cow (Elsie) laugh.

[Elecraft] Halicrafters S-38

[Kidder, George]

The S-38, like many BC receivers at the time, was an "AC/DC" rig, with 
the chassis potentially hot if you weren't careful.  Nearly eliminated 
myself in the basement trying to attach a Q-multiplier to it.  This was 
better than 60 years ago.

I use a battery maintained by a charger system - complete 
uninterruptible 12V power.  Guess I'm  "almost nobody".

Having a dead battery corroding in your radio is not a good thing.  And 
for the work required to remove it, you might as well replace it and get 
another decade of service.
