Re: [Elecraft] KPA500 fan won't shut off

2019-11-25 Thread Jack Brindle via Elecraft
That won’t do any good. The main firmware has shut down at that point. The fan 
is running because the relay is stuck, which is not something that firmware can 
fix.

Call tech support.

Re: [Elecraft] KPA500 fan won't shut off

2019-11-25 Thread VK5GR
FAN CTL = NOR

FANs are idle while the amp is turned on - amp ambient temp was 27C at the
time (it was powered up and had been idle for about 20 minutes).

I then turned the amplifier off via the front panel push button. I would
have expected the FANs to start up for about 10 seconds as they discharge
the 60V rail supply but instead the FANs continue to run. the only way to
turn them off is to unplug the amp from the mains supply.

It is definitely a fault condition and not a menu selection.

Thoughts?

What is the value in the menu for FAN CTL?   If at NOR then the fan 
should be off until the temp hits about 50º C.  It will then increment 
up one speed value about every 5 degrees temp increase.   What is the 
TEMP value showing?   Should be about room temp or 22 to 25 C

Re: [Elecraft] XFIL on K3

2019-11-25 Thread Keith Trinity WE6R
A hidden feature if you you want to toggle thought ALL filter slots, 
even if they are empty or not selected for the current Mode!
*Go into any config menu starting with FL  (except for FLTX);  (IE "FLx 
BW", or "FLx FRQ" or "FLx GN" or "FLx ON")
Then while in that menu, tap 6/XFIL, and it will got rotate though *ALL* 
the slots.

This is good to see if you have a filter or not in a slot.
Also good to use if you want to use the AM filter on FM if you have 
adjacent channel interference.

Or force a filter on a mode that is not selected.

[Elecraft] Multiple antennas on one port (KAT500 KPA1500)

2019-11-25 Thread Andy Durbin
"With just two antenna ports on the KPA1500, there are only two quickly 
accessible tuning solutions per frequency if using both ports. If using only 
one port and an external antenna switch, a common choice in many stations, 
finding the correct tuning solutions can't be done fast enough to prevent a 
fault."

The KAT500 remembers the most recent 6 tuning solutions for each frequency 
"bin".  The saved solution includes the antenna port in use when that solution 
was stored.  I would guess that the tuner in KPA1500 does the same thing.  This 
means that the tuner already has enough non volatile memory allocated to cope 
with more than one antenna on each port.  The problem would be letting the 
tuner know which antenna is in use on the current port before RF is applied.

If the tuner had the option to tag each tuning solution with antenna port and 
also external antenna selection, then up to 6 switched antennas could be 
accommodated on 1 port with little, or no, increase in NVM overhead.   If the 
external antenna switch provided a position signal then that signal could be 
provided to the tuner by a new serial command or AUX bus command, or by 
extension of the existing antenna selection commands.

There would be lots of details to sort out and I suspect it would be easier to 
store the multiple tuning solutions for different externally selected antennas 
in a separate controller.  The idea is the same though - if the system knows 
what what port is in use, and it knows what antenna has been selected on that 
port, then it can instantly recall and apply the last remembered tuning 
solution for that switching combination for the current TX frequency.

Andy, k3wyc

Re: [Elecraft] K3 Drive Levels

2019-11-25 Thread Eric Norris
I noticed the LPA was getting quite hot when running wspr at 5w for days at
time--even with 15% tx cycle.  My workaround is a six-inch computer fan set
vertical on the right side of the k3, blowing quiet air on the right side
and bottom of the k3.  It seems to work.  I also have used a tiny 2"
squirrel-cage fan blowing air under the XV144 during high duty-cycle modes
in WSJT.  The five high-volume fans I run on the Henry 2002A, to keep from
blowing tubes, on the other hand, are a freight-train-in-a-shack (TM).

Re: [Elecraft] K3 Drive Levels and the SPE 1.3K-FA

2019-11-25 Thread Roger D Johnson

I purchased one of these amps about two years ago. I expected it to require
50 to 60 watts of drive for full output but it only took half that. I was
worried about screwing up and hitting it with 100 watts from the K3 and
blowing the final transistor. I knew there was a pad on the input and I
figured it would be fairly simple to increase the attenuation 2 db or so.
I pulled the covers off the amp and discovered that there were 2 pads on
the input! The first was TO-220 style resistors mounted to a chassis rail
and the second was conventional wire-wound resistors mounted on the PA
circuit board. Replacing the TO-220 resistors looked like it would involve
quite a bit of disassembly and probably would void the warranty. Tack soldering
some resistors on the second pad to increase the attenuation would be much
easier and could be easily removed if it had to go back for service. Problem
solved, right? Nope. I discovered that the amp senses drive power after the
first pad. This meant the amp kept tripping off with overdrive warnings! I
contacted the factory to see if there was an adjustment I could make and was
told it would have to come back for "realignment"!

I now have a KPA1500!

73, Roger

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,

Re: [Elecraft] Unexpected K-POD frequency excursions

Peter, 

Contact Elecraft support on this issue. Sounds like poor grounding/ESD
protection. They may have a service bulletin to fix the issue.

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?
