Re: [Elecraft] Unexpected K-POD frequency excursions

[Peter Dougherty]

Nope, the K-pod connects directly to the K3s via an 8-pin flat cable,
terminated with RJ-45 connectors. The mouse is a USB wired mouse.

Hi Peter,
Just an idea. Does the ipod generate a virtual serial port?
Do you have a bluetooth mouse?

Not quite my setup but I've recently had trouble with a usb serial cable
randomly interacting with the Microsoft bluetooth mouse and the serial cable
becomes intermittent. The mouse jumps randomly but also makes the serial
cable behave strangely. I'm wondering  if a similar thing is occurring to
you. My solution was to uninstall the mouse from device manager, shut down
and restart...win10 pro installs a fresh driver for the mouse.

Subject: [Elecraft] Unexpected K-POD frequency excursions 

 

Hi all,
In CQWW this weekend I ran across a problem that's been plaguing me in
previous contests too. With the K-pod connected to the radio (K3s) using the
supplied cable I'm finding that the main VFO QSYs down about 100-200 Hz on a
random basis. I tried loading the flat cable up with Mix 31 ferrites to no
effect. I haven't thoroughly tested this on all bands, but it definitely
occurred on 20 through 160. It was not a regular occurrence; maybe every 2-3
minutes it would happen. When I engage the VFO lock on the front panel of
the radio it stops doing it.

I has also been know to shut the radio off once every few days when I touch
the K-pod, which I'm attributing to static electricity. While I love the
functionality of my K-pod, I had to take it offline due to the frequency
excursions. I'd like to get a fix for this if at all possible. Suggestions?

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   I could not find an open space to run the twenty meter net. The 
forty meter net started when the CQWW contest faded away. There was QSB 
on everyone I worked.  Those farther east had slow waves.  KG7V is just 
across the Columbia River from me (and a little up the coast) had a fast 
flutter from S2 to S5.  K1SW was able to check in again with his KX2 
running 12 watts.  S0 to S3 but with repeats I got more information.  
W0CZ had a strong signal but could not hear me.  His S5 to S7 signal was 
easy copy.



  On 7047.5 kHz at z:

K0DTJ - Brian - CA

K6PJV - Dale - CA

W6JHB - Jim - CA

KG7V - Marv - WA

W0CZ - Ken - ND

K1SW - Dick - CT


   I lost the use of my keyboard a little earlier today.  After two 
keyboard changes and a few reboots I determined the hardware was most 
likely not the culprit.  As I was switching keyboards I held down a key 
and a few characters appeared.  Very slowly.  So I queried the Ubuntu 
site and found 'slow keys'.  I dove into the settings and turned it 
off.  Seems you can turn on this feature if you hold the shift key down 
too long.  You learn something new each day.  But for a while it was 
like Bach's "Rage Over the Lost Penny".



   Until next week stay well,

   Kevin.  KD5ONS

Re: [Elecraft] XFIL on K3

Don, no apology necessary. But this is one item I was cautioned about before I 
purchased. 

I didn’t see your response until after Dick had responded. I’d have been 
confused!

I’ve  ewww had my K3 now for ten years and a local guru. But I can close my 
eyes and Stan at any page in the manual and find something I don’t 
know/understand.

Re: [Elecraft] KAT-500 problem

[Edward R Cole]

Something is acting as an antenna.  I made several hundred mile 
contacts with a 100w light bulb "dummy load" on 40m in the 1950's.
Might be ground system is working as antenna or radio as found 
connection via other equipment.


Be interesting to find out what you discover.

[Elecraft] KPA500/KAT500 remote utility apps

[kd4iz]

Wayne and Eric,

Is there a possibility of creating/enabling a window position and size save 
function in a future revision of these two remote control apps. They works very 
well, but pop up in dead center of my "Screen 1" display on any fresh start. I 
use "Screen 2" for radio apps have not been able to figure a way to make them 
stay or return to  where I want them.

That small addition would be a big plus and should be a straight forward mod. 
Thanks for adding it to a "for consideration" list!

Hi Dave,

These are two different programs. The first one you show in the jpg, with less 
color, is the KPA500 utility, which is primarily designed for downloading code 
to the 1500 and reading back status etc in real time. It also has very basic 
remote control.

The KPA500 Utility is downloaded from
https://elecraft.com/pages/firmware-software
under the 'Amplifier Firmware and Software' tab.


The second 'more colorful' program you show on your webpage is the KPA500 
Remote . It is the full featured remote control program for the KP500.

The KPA500 Remote Software is downloaded from the same 
https://elecraft.com/pages/firmware-software
page under the  'Logging and Control Software for the K-Line and KX-Line'  tab.

[Elecraft] Legacy K2 Tuneup, Rescue, Build Services

[Alan D. Wilcox]

Hello,

Does your K2 need repair? Tuneup?
Want to sell it, but it needs some attention before offering it for sale? 

In addition to tuning your rig, I can also rescue a building project you might 
have started some time ago.

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768 

Photos of the popular "Twins" -- the KPA100 and KAT100 in EC2 enclosure --  are

The most common source of RF noise from video monitors is the 
switch-mode power supply that virtually all of them use. A good way to 
avoid that noise is to buy a monitor where the power supply is an 
external wall wart that can 1) be replaced a vintage linear power supply 
or 2) run from the 12-14VDC system in the shack.


I have had success with this approach with a few 23-24-in Samsung models 
that run from 14VDC. Larger and fancier models run from higher DC 
voltages, for which linear DC power supplies are much harder to find.


Some noise may also be generated by the monitors themselves, which can 
be suppressed by winding video and power cables through #31 Fair-Rite 
cores.


The only monitor I've seen that was had trouble with high power RF was a 
Samsung model that used touch-screen controls. It went nuts when I 
transmitted on a nearby antenna. It was given to me by another ham who 
had the same problem.

Re: [Elecraft] XFIL on K3

[Don Wilhelm]

My apologies for my note yesterday on this subject, it was incorrect.

I have just been informed by one of the Elecraft engineers that I erred 
in my statement that the K3 filters could be in any order, so Bill was 
right.
See Dick's comments to me below.  I did not see that note in my early K3 
manual which does state that the filters can be installed in any order - 
I did not read the remainder of the note.


Also note that if you have the 13kHz  filter, it must be in the FL1 slot.

The FM transmit filter is hard-coded as FL1. So if you need FM transmit, a 13

[Elecraft] KAT-500 problem

[Andy Durbin]

KAT500 antenna port isolation is not impressive, at least not after using an 
Alpha Delta 4 port switch.  I have ANT-3 port connected to an Alpha Delta 
switch that selects either my dummy load or a back yard antenna.  The other 
KAT500 ports are connected to a 40 m dipole and my SteppIR.

Several times I have not realized I was still selected to the dummy load as I 
was receiving so many stations.  Not worked anyone in that configuration yet 
though.

It doesn't surprise me a bit that some sneak path could bring a signal in 
through the KAT500 with no antenna connected to an ANT port.  One of my wish 
list station improvements is to have a remote controlled antenna switch that 
has more ports than I have antennas.
