[Elecraft] Elecraft CW Net Announcement

[kevinr]

Good Evening,

   Fire danger got very high today.  It will be hot again tomorrow.  
The highway to Seaside and Astoria was pretty full yesterday.  Hopefully 
none of those campers will start a fire. Luckily most of the heat will 
be gone by Wednesday.  There were some foggy mornings last week so the 
berries are doing a little better.


  Remember the time change for forty meters.  I'll be monitoring by 
0030z but won't start calling until 0045z.  The band may be a little 
better with the day just a little shorter.  I expect the QSB will be 
present on both bands.  It is time to pull down my extra long doublet 
and check for wear.  It has been up for a few years without a problem.  
It can receive on 160 meters but I can't match it close enough to 
transmit.  When I get it down I can check the measurements.  Or cut a 
new antenna for 20 and 40 meters.


Please join us on (or near):

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 7047 kHz at 0045z Monday (5:45 PM PDT Sunday)

   73,
  Kevin. KD5ONS

Lightning aside, when will those of us who have signed up for upgrades 
be told whether or not they will be accepted?

Besides the most likely Comm Port, then obvious Antenna, I have seen

DC power cord, ground, Paddle/Key, Key-Out to Amp etc.

Re: [Elecraft] Lightning Season, disconnect COMPUTER etc.

[Eric Swartz]

One note: Keith mis-spoke when he stated "Spare K3 board supplies are low
or gone".  We certainly are not stopping support and repairs for the K3 and
K3S. (Of course there are some lightning damaged radios that are not
economical to repair.) Though some repairs may take longer as replacement
parts are ordered.

What is happening is that we are pivoting from board swaps to component
level repairs on many K3 and K3S boards.  Also, we will still be building
boards for these radios that can be sold for upgrades and repair swap outs
on a case by case, lot basis, based on demand. (There is a sign up list
for upgrade / spare board requests on our web page for the upgrade boards.)

[Elecraft] There is a new release of Win4K3Suite

[Tom]

Hello,
There is a new version of Win4K3Suite available.  This release includes
direct logging into Log4OM version 2 and some improvements to the ClubLog
spotting module.

Win4K3Suite is a full featured control program for the K3/S, KX3 and KX2.
It has a built in Panadapter that works with LPPAN and a sound card, as well
as the SDRPlay RSP's. It supports the KAT500, KPA500/1500 and the KXPA100 on
most of the above radios.  
A unique feature is that is has 6 built in Virtual Radios, each of which
works just like an Elecraft radio.  This allows sharing of a single COM port
with up to 6 applications.  It also has a built in HRDLogbook server and the
EiBi Shortwave database.
You see more information here:
https://www.youtube.com/results?search_query=win4k3suite
and download a fully functional 30 day trial at va2fsq.com

[Elecraft] KX3/KXPA connection

[john daws]

Have had this working fine for a year until 2 months ago KX3 connected
briefly to the KXPA100 and then cut out.

The SYS LED light showed on the KXPA100

Have replaced PSU believing it to be a fault here.

Have sent KXPA100 to Waters and Stanton (UK) for inspection and returned
with clean bill of health.

Reconnected using the 'KX3 to KXPA100 adapter cable' and replaced both 25
amp fuses.

Same 'fault': KX3 cuts out straight away and no response at all now from the
KXPA100

Could a new set of adapter cables now be the answer??

(The KX3 works fine on the KX33 low power RFI  supply)

Not a very technical person so please be gentle!!

Thanks for any thoughts 

John

Re: [Elecraft] Elecraft K3 Problem

[Mike K8CN]

Hi Per-Tore,

Can you identify which transistor (or other device) on the LPA module is
getting hot in transmit mode?

The drain terminals of MOSFET PA transistors Q4 and Q5 receive +12V
regardless of TX or RX mode, but the gate bias voltages are applied only in
TX mode.  Unless there's a problem with the bias regulator circuit (U1), the
RF amplifier chain on the LPA module should not be getting that warm. It is
also possible that one of the RF power transistors may be getting hot
because it is no longer making good thermal contact with the bottom cover
panel - it would be good to check the tightness of the three screws holding
those transistors against the bottom panel.

Is it possible for you to carefully extract the LPA module from the main RF
board? That requires removal of the rear panel of the bottom cover, and you
may need new thermal pads for the RF transistors if those pads are damaged
by removal of the cover panel.   If you can remove the LPA module, you might
try RX mode ONLY with the Power control set to 0 (to ensure that the KPA3 PA
is bypassed by its relay K1) and see if your receive sensitivity is
restored.  

The output side of the LPA module is nominally connected only in TX mode to
the antenna path via diode D1 on the LPA module, and if the D1 switch is
operating properly one would not expect the high attenuation of signals in
RX mode.  The output of the LPA module is also connected to the input of the
100 W PA module at the same point on the T/R switch circuit, but that module
is bypassed by relay K1 on the KPAIO3 board.

I'm not yet sure how the overheating of a device on the LPA board is
connected to the loss of RX sensitivity.  If the diode switch D1 on the LPA
module has failed shorted (unlikely), then it would leave the output
circuitry of the LPA module bridged across the antenna signal path in RX
mode.

Keep us posted on what you learn!

73,
Mike, K8CN

Re: [Elecraft] K4 Questions

[Grant Youngman]

I recall that Eric answered a question about that during one of the two 90 
minute Q&As at the Expo.

I think he said it may be available at some point, but indicated it was 
possibly over ethernet (?) rather than USB.  But I could be mistaken, since I’m 
lucky to remember my name unless I look at my driver’s license … if I can 
remember where that is :-)

Whichever it is, it didn’t sound like it was going to be a first release 
feature.

Sync AM mode appears to not be working.  Been though B-Set selecting mode(s),,  
Not “tracking”, envelope detection OK.  Latest firmware installed (5.67MCU and 
2.88DSP).  DSP f/w fix?

[Elecraft] General Purpose Outputs on KX2

[Ken Simmons]

Is anyone using the General Purpose Outputs on the KX2 that comes with the 
KXIO2 board? It says they are user programmable, but to what extent?

Thanks.

Disconnecting is not a reliable way to protect your home and station from a
lightning strike. A strike can induce high voltage into your home wiring
without the antenna being connected and cause a lot of damage. There are
many papers on lightning protection, proper single point grounding is a good
start.

[Elecraft] NJQRP Skeeter Hunt - tomorrow!

[Larry Makoski]

Tomorrow, Sunday August 16th is the 9th running of the NJQRP Skeeter Hunt.

277 of you have signed up for Skeeter numbers, so there should be lots of
activity out there. Our fingers are crossed that the Propagation Princess
will be in a good mood and will cooperate. This is an all time record
number of Skeeters - NJQRP thanks each and every one of you for
participating. It's not too late to sign up for a number, I'll be issuing
them right up to about 10:00 AM EDT tomorrow for any late comers - just
send an e-amil to w...@arrl.net and I'll send you an e-mail back with your
Skeeter Number for 2020.

If anyone is fuzzy about the rules, please visit http://www.qsl.net/w2lj -
the rules are easy and not cumbersome. The exchange is easy and the main
goal of this exercize is to provide ample fun - no jumping through hoops
here.

Lastly, in these COVID times, please remember to stay safe. Back yard
operations with a temporary antenna and a power source other than your
home's commercial mains count as portable for the Skeeter Hunt. No need to
go off into the public if you feel safer at home. If you do venture out,
please keep yourself safe by observing your area's restrictions (i.e facial
coverings, social distancing and above all Common Sense). We at NJQRP want
to have you all back next year for the 10th Anniversary of the NJQRP
Skeeter Hunt.

Go out there, be careful and have fun! Hope to hear you and get your call
signs in the log!

72 de Larry W2LJ - Contest Manager - Skeeter # 13
