Re: [Elecraft] K2 Filter question

[Michael Babineau]

It is also worth mentioning that the KAF2 (audio filter and real-time clock) is 
 a good addition for CW reception.

IMHO it does help a lot when copying weak signals and also having the real-time 
clock is useful.

Few things in radio life bring as many diverse pleasures to bear on a

say that most K2 owners hang on to them to the end. Welcome to the "club."

Not with equipment test, but just buy listening to both receivers and judging

Re: [Elecraft] KPA-500 Running hot on 20m

[Fred Jensen]

It also is fairly sensitive to how tightly enclosed your KPA500 is in 
your station equipment configuration. Mine came on high-fan often when 
on RTTY, or [fruitlessly] calling CQ in SS CW on Sun.  I finally moved 
it out of it's "cubbyhole" under the shelf assembly, and it stayed on 
low fan all the time, which I couldn't hear with the cans on.


For my K2/100, the heat sink got very hot with repeated [unanswered] 
CQ's and on RTTY.  I mounted a computer fan on top of the heatsink with 
a tab of velcro, blowing down.  Heat sink stayed cool to the touch with 
80-90 W on RTTY.  I am repeatedly amazed by thermodynamics. [:-)

[Elecraft] P3 SVGA works, but text stops

[KC6CNN]

Okay today I was working with the P3 as to my earlier post hihi. 
I was sending psk, rtty and cw with the keyboard connected to the P3. 
All of a sudden the keyboard stops responding to any key or command. 
The P3 and SVGA are still showing the bands and waterfalls and all is
functioning right except for the keyboard will not type. 
I have done this before with no problems, I have not changed anything else
except adding a few more control alt t macros. 

I have reloaded the latest firmware and went and checked all my settings. 
I turned the P3 off and back on and it works for a couple of minutes and
then stops again. 

Any suggestions?

Thanks

[Elecraft] KPA-500 Running hot on 20m

[W0MU Mike Fatchett]

I was running the RTTY contest this weekend and expected to see higher 
than normal temps but on 20m and maybe 15 the amp was running 65c and up 
where the highest speed fan would come on. Generally in RTTY I would up 
the normal fan a couple of notches and it would be fine.   I was not

Nothing much has really changed here so I am a bit confused what might 
be going on here.

Re: [Elecraft] Problem with my K2

[Don Wilhelm]

Listening to the video, I would not think this is anything I could call 
a "spurious".  It sounds more like a source of broadband noise.

Check your power supply and any "wall-wart" supplies in the vicinity.
An open antenna jack can pick up noise, so test again with a dummy load 
connected.
If the noise persists, I think you will be looking for a bad solder 
connection in the K2.

Please everyone, we don’t need the “appliance operators vs builders” argument 
here. Those are flavors of amateur radio, not levels of goodness.

I was an appliance operator in 1970, with a BC-348 receiver and an ARC-5 
transmitter. My Elmer got those working for me.

Re: [Elecraft] Elecraft Support

[kev...@coho.net]

I grew up with a stack of pristine ARC-5 receivers.  My dad had worked 
on them during WWII and bought half a dozen when they were cheap in the 
50s.  When I opened them up I found each part was placed just so; the 
resistor color bands all lined up with the tolerance bands in lock 
step.  I just could not bring myself to touch them with a soldering iron 
even years after dad had passed away.  It would be like dismantling a 
sculpture.

[Elecraft] KPA-500 fix

[Andrew Faber via Elecraft]

I thought I would share a fix to my KPA-500 with the group in case someone 
else might have the same problem.
I have an old amp (two-digit serial number), and it has performed flawlessly 
until yesterday. Suddenly the Operate-Standby button stopped working, and 
then I noticed that other buttons worked, but did strange things.  The cure 
was simply to take off the front panel and reseat the two ribbon connectors. 
Actually I could only reseat the large connector at the panel end, and the 
small one at the board it plugs into in the main body.  The other end of the 
large connector is at the back of the amp and not accessible without 
considerable disassembly.  And the panel end of the small connector was 
stuck on so tight that I was afraid I would break something in removal.  But 
reseating 2 of the 4 possible connectors did the trick.  Now it seems to be 
back to normal.

Re: [Elecraft] KUSB Drivers for Windows 10

[Dick Grolleman]

Hello Pete and All

Windows 10, does an automatic update on the original driver. This will not work 
with the old Profilic cable.
There is a fix for it. Follow the link below and install the Profilic driver 
from there. This did the trick for me.

http://www.ifamilysoftware.com/news37.html

I still use the same cable purchased in 2008 with my K3 with Windows 10.

K2 spurious?

I'm having this problem with my K2. This "QRM" comes even if my antenna is 
disconnected! Don't know what it is!

[Elecraft] Elecraft Support

[Edward Kacura via Elecraft]

Yes, they are the best when it comes to support !
I had my KX3, s/n045, less than 10days and a problem developed.
I shot an email to Elecraft at 10pm on a Sunday nite, shortly Wayne answered 
me, much to my surprise !
It was an early firmware problem and he said he'd be on it Monday morning !
I get an email from him Tuesday to call him personally.
He spent an hour on the phone with me while I reloaded firmware and set the 
radio up again !
I've not had a problem since in almost 5 years now.
I was so impressed with Wayne's personal service and help !
I'll never buy anything but Elecraft products ever again !
Thanks so much to everyone there, you folks are the best IMHO !!

Re: [Elecraft] K2 Filter question

[Robert G Strickland]

Mike...

The K2 does not have individual filters like the K3. It has a set of 
serial crystals in a lattice filter arrangement [sic] that can be 
voltage biased to yield various effective filter widths from very narrow 
to broad. There are provisions to select three/four  pre-programed 
filter widths per mode [not quite sure of this one]. The various widths 
are set up in the filter calibration mode of the K2. W3FPR Don Wilheim's 
site has all sorts of information on general principles as well as 
step-by-step instructions for setting the filter widths in the K2. An 
auxiliary program called "Spectogram" is used to portray the filter 
widths on the computer screen so that one can see the shape/bandwidth of 
the filter during setup. In my experience, the filtering system in the 
K2 is quite effective. Others will no doubt add to this limited 
description of the K2 filtering method and results.

Re: [Elecraft] Elecraft Support

[Clay Autery]

Not completely  I chose Elecraft specifically because it's the only
major maker that allows me to participate in the process of building the
device.

Since assembling my K3s/P3, I continue to improve my knowledge and
skills in theory, design, and construction.

I've always gotten as much or more enjoyment out of the design and
construction phases of projects as from the operation thereof.

Building is not dead...  not at my house anyway.

Mike,

The K2 has a built-in 5 pole filter on the RF board that you can set to
variable widths using the CAL FIL menu - you must have the internal counter
probe to change the filter settings.
There are 4 filter settings for each mode.

These are not "roofing filters" as used in the K3, but IF crystal filters.
The filter type in the base K2 is of a Cohn design and the width can be
changed as I stated above.  Its design width is about 500Hz and gives a nice
passband from about 1.5kHz down to about 200Hz.
It can be widened out to SSB listening levels, but the passband becomes
quite ragged at those wider widths.  It is however suitable for SSB
listening.  The filter on the KSB2 option board has a nice flat passband.

The KSB2 option (for SSB) has a fixed width 7 pole filter.  The early
filters were 2.1kHz width, but more recent filters are 2.4kHz.
Elecraft has a capacitor kit which will allow you to change the filter
width.

The crystals used in the K2 filter were upgraded to better speced crystals
at SN 2560.  I would recommend that K2s below that SN be upgraded with the
new crystals.  Elecraft sells a kit of matched crystals at a very reasonable
price a set of 7 for the base K2 or a set of 14 for both the base K2 and the
KSB2 option.

Re: [Elecraft] Elecraft Support

[Jim Rogers]

And I agree with you and Kevin Ron.  Sometimes with growth cracks occur 
and you might just fall through one now and then. But you remain 
faithful to the cause. There is one Elecraft radio that will never leave 
my shack and that one is my faithful K2/10 with that wonderful receiver. 
It has the battery supply and that great antenna tuner and every option 
except the 100W amp.

[Elecraft] K3: I must have changed something ?

[Ed Stallman]

While listening to CW and S meter setting at zero , the first dit or dah I
hear is ear piercing .. My CW sidetones do the same ! I've always used AGC
Fast in CW , Tried AGC Slow  also tried adjusting AGC-THR and AGC-SLP.. I'm
sure I'm not giving enough information ... FW is 05.14 , SN 32xx. Should I
install latest FW ?

[Elecraft] Elecraft Support

[Johnny Siu via Elecraft]

Don and all,
Yes, I have been contacting Gary for more than a decade for various elecraft 
support matters.  My first contact with him was for my K2# 14xx.
He and other support staff from Elecraft do give a personal touch and I can 
feel their enthusiasm.
One of my main reason to stay with Elecraft is their support services. Product 
support is important to me because I am outside USA.

Jim and all,

Yes, I remember those "good old days" when the only Elecraft support 
person was Gary (I was one of the K2 Field Testers).  Unfortunately as 
the Elecraft product line grew, the number of support persons has grown 
too - it now numbers 4 - David, Craig, Howard and Gary, and the Monday 
morning support email load is large.
Problems that the support staff cannot handle are still passed along to 
the engineers, but that may be in the background while the support 
people handle the major communications back to the customer.

Yes, I am close to the Elecraft team (particularly the support and sales 
folks), and do most of the repairs on the K2 and other "thru-hole" kits 
in the Elecraft line.  So I am quite familiar with that part of their 
operation as well as their problems.  Personal phone numbers are no 
longer given out (protections for the employees except in extreme 
cases), but you will still receive personalized customer support service 
via email or they will often phone customers with problems.

I do serve as support for those "Thru-hole" products when Gary is not 
available, and I can say for myself that (from me) you will receive 
extended personal support when required - yes even help with a lifted 
solder pad.
I am in North Carolina, and am in a different time zone than Elecraft, 
but that makes little difference,  we still communicate with each other 
and the customers when the need arises.

73,
Don W3FPR
