Re: [Elecraft] [KX3] KX2 owner discovers Heaven/P

Truly a neat location!  The place I went for the eclipse was no where near as 
cool... a boat landing at the Congaree river..  but there were pump up boats 
going out with dogs and the like to visit vegetation islands in the river.. 
I just stayed on shore because my back and small boats do not do well 
together...

Here is a quick video operating my KX2 from a tiny island feeding a 20m end fed 
half wave (64:1 transformer and 32ft of wire) hanging from a 33ft fiberglass 
mast. The island is in Huntington Lake, CA in the Sierra mtns above Fresno. 
Still pics can be grabbed from the video and near the end of the video I'm 
holding up the KX2 as the drone flies by. The caption could simply be " 
Elecraft Island".

Re: [Elecraft] Unplugging the radio to protect it

[Bill Blomgren (kk4qdz)]

 off list because it isn't on topic.
An old retired friend worked in Telcom for decades (including the shore station 
that AT had in Florida to connect to their subscribers in the Caribbean...
He mentioned that the really LONG underground fiber links across the country 
(down 6-8 feet) attract lightning like crazy.. where lightning is hunting for 
the steel wire down the middle of the bundle that is used to find the line if 
there is a problem.
Well, lightning finds it a LOT.. and causes a whole bunch of HOT in one spot 
that typically microshatters bout 1/2 mile of fiber in each direction.. or at 
least used to.
no idea if the ZOT! on the steel wire damaged equipment at either end.. but it 
was a big problem.

Maybe it was something with the setup.

That's an understatement.

Running kilowatt-level power on the same band to two antennas only 20 
feet apart is simply crazy.  I don't know what input protection the 
KX3's have, but they almost certainly kicked in and being inherently 
non-linear they would have generated all sorts of high level trash on 
the front end.  It would be interesting to see the math, but I think 
you're lucky you didn't blow the heck out of both front ends in spite of 
the protection.

The K3 is more complicated and has more options. The KX3 has four internal 
options — charger/clock, ATU, roofing filters, and 2m module. The K3 has far 
more than that. Also, the K3 is commonly used in complex base stations, with 
multiple antennas, external power amplifiers, and so on.

So, more discussion about the K3 is normal.

At this point, I think Elecraft has sold about the same number of K3’s and 
KX3’s.

Finally, it is common practice on this list to sign e-mails with your call sign.

Re: [Elecraft] My KX3 desk microphone project

[Bill Blomgren (kk4qdz) via Elecraft]

When it comes to microphones, you get into religious wars.  I happen to like 
doing live recording work with a stereo ribbon mike that has the capsules 
basically touching vertically.  (Open sound, natural sound field.)
A single point pickup results in a 'coherent' recording.  The sound is in phase 
at that one point in space
Add additional capsules, and you end up with multiple unknowns on 2 equations.  
(the 3 point omni decca thing for example.) Simply using a pair of mikes in 
front of a group gets the cleanest stereo recording.. or a single mike to get a 
mono recording.
Same thing applies on broadcasting.  (That is why they use noise gates to turn 
off idle mikes...so that the pickup of the guy talking isn't added in and 
cancel him out.)

 In my opinion much, much better words should of been choose than

 Seriously misguided would be trying to run a 12V device off 120V. 

Why? If an idea is seriously misguided, saying so is entirely 
appropriate. I did not expand on the advice because this is an email 
reflector dedicated to Elecraft radios, not microphones.

There are (at least) three reasons why an array of microphones is a 
really bad idea. First, really good sounding mics to work with our 
radios are widely available cheap. Second, a microphone is an 
electroacoustic device -- it collects sound at a point in space and 
converts it to voltage. A microphone at a different point in space 
collects different sound -- there is a difference in time between those 
sounds, which results in a difference in phase. The difference in phase 
results in peaks and dips in the frequency response, which in the audio 
world is called comb filtering. Third, one mic loads another 
electrically, degrading the performance of each.

Third, those of us working in pro audio learned a long time ago that one 
mic feeding a single channel is always better than one for picking up a 
single sound source like the human voice. Putting more of them in 
parallel does not make them work better.

When you see two mics on either side of a podium, it's an indication 
that whoever put them there didn't understand that. As the talker moves 
side to side, the sound of his/her voice changes due to the 
cancellation. Almost 40 years ago, I did a couple of big outdoor sound 
reinforcement gigs for the President, and the White House sound 
engineers DID understand that -- they studied at the same workshops that 
I did. They had Shure build a special mic for them with three capsules 
in it, each coming out on their own shielded twisted pair. Two went to 
me, the second was for redundancy -- in case wiring for the first one 
failed. Each went to a different input of my mix console. The third went 
to them for their recording.

Re: [Elecraft] KX3 Questions

[Bill Blomgren (kk4qdz) via Elecraft]

The 4 meter module is not usable in the USA.. the 2 meter gets you an all-mode 
2 meter transverter. That plus an external amp gets you side band on 2 meters, 
cw and so on if you want more than 2 or 3 watts.




4 meters is in the middle of a VHF TV band here in the states, and the FCC has 
no plans to allow operations in that span, since there are active TV stations 
there.

Larry, I assembled a KX3 and it’s companion KXPA100 amp 3 weeks ago, and it is 
an outstanding combo. I’m replacing a Kenwood TS-480HX (an outstanding device 
also) which I ran with an Ameritron ALS-600S 600-watt linear. With some 
balancing and shielding I will be able to run the KX3 + KXPA100 into the 600 
watt linear. So, I have my super compact QRP radio that I can put in my back 
pack and sit on a lawn chair with a Buddy Pole on top of a mountain, or the 
high power base station on my desk at home with the mini-beam. Cake and eat it 
too. The KXP3 pan adapter for the KX3 arrives today — my weekend project.
I’ll suggest the roofing filter especially for CW. Did not get an antenna tuner 
for either the KX3 or KXPA100, but might reconsider that later, since I have an 
auto-tuner for the big linear. Had no interest in using the KX3 on 2M and 
actually for the cost, you could probably find a very nice 2M rig.
Assembly suggestion: they provide you with a lot of little teeny tiny screws. 
Get a cupcake pan or ice cube tray and separate all the parts and label them. 
Very difficult to tell a 5/32 screw from a 1/4. Tweezers help. And the customer 
support is extraordinary.

Hi All,

I like to haunt the bargain and close-out websites.  This item showed up 
on Rakuten's website (formerly Buy.com).  A 30 amp solar charger for about 
$20.00!  Here's a link:

http://patazon.shop.rakuten.com/p/patazon-30a-solar-panel-power-battery-charge-controller-regulator-12v/264381220.html?scid=em_Promotional_20140909DAILYadid=17653

I'm not familiar with the product, but it seems to be something that could 
be useful for those of us who like/want to do solar panel charging from time 
to time.

I have a couple of different sets of solar panels--one set I keep in my 
motorhome, and the other is at home.  Since I only have one controller, this 
might be a good opportunity to eliminate the need for carrying the one 
controller back and forth.  I'm curious, though, if anyone else has ever 
seen/used this particular controller, or one from the same manufacturer.

More and more I hear about others who have gone to solar charging, and I 
have lots of opportunities to do the same.  Dry camping is something I do a 
good bit of, and keeping the rigs running on battery power usually means 
needing a generator along.  If I'm running QRP it isn't a big deal, but if I 
want to run a bit higher power, then battery consumption gets to be an 
issue.

Anyway, I thought I'd pass this on in case anyone else might find it to be 
of interest.

Then there was a toroid that was wound incorrectly... in a K2 kit, purchases of

through a toroid, Then a K2 with a problem with drift. And then several

Not a lot of trouble with toroids, I'd say.

Re: [Elecraft] Headphones and extension cable - leave plugged in?

[Bill Blomgren (kk4qdz) via Elecraft]

In the broadcast stations I worked at over the year, the audio patch panels had 
a lot of activity.. but there were basic ground rules to make sure something 
'bad' didn't happen in the middle of a live show..

1) you plug and unplug the connection 2-3 times before leaving the cable 
hanging.  (Periodically they got cleaned and lubed, but the connections will 
oxydize over time

2) you always test the connection with the studio so that you don't have a 
surprise.

With video cables, it was not as common to have issues, because there was 
always a plug in the connections for the 'normal' feed. (Video didn't use the 
contacts in the patch bay to provide the 'normal' connections.

There were some audio cables that were left in place for months in some cases.. 
Periodically they would get the same reseat action to make sure that there 
was no problem.  (Example: control room reconstruction.)

The sheer volume of contacts and cables in that environment makes replacement 
difficult to impossible (well, until the switch to HD, which meant everything 
had to change..)

 IMHO, the trouble of
 removing the plug and plugging it back in is not 
 worth the cost of a replacement cable.  I
 suspect it has worked fine for 
 several
 years.  If not, look for a better quality cable.
 
 In case the problem is caused by contact oxidation, removing the plug 
 and  re-inserting it several times should wipe the contact area
 and  restore it to normal operation.

Very cool!  This brings up the question of what antennas folks are planning to 
use with the 2m/4m modules.  I am anxiously awaiting my 2m module and can make 
use of the waiting time to read up on VHF antennas (I'm not much of a VHF guy).

Hi all,

Since we don't have 4-meter band privileges in the U.S., we sent a KX3 4-meter 
module to Peter Waters in the U.K. for test purposes. Peter arranged a test 
QSO on 70.190 MHz (SSB) with another station, as documented in this video:

Elecraft KX3 on 4m / 70MHz

Both stations were using a dual-band (6 m/4 m) antenna from InnovAntenna, 
though I haven't been able to figure out what the model number is yet. Peter 
describes it as single-feed, very compact.

For information on the KX3-2M/4M option, see the FAQ:

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Bill Blomgren (kk4qdz) via Elecraft]

 And another warning: Nearby (like next door) lightning will be picked up by 
ANY long wires which end up acting as antennas.

I did computer repair in Florida.  I had a time share/multitasking system in a 
law office that had thousands of dollars in damage after the building next door 
got hit.

The terminals were plugged into serial lines back to the central system.  So 
were the printers. (Think: 6 processor unix type system with a network inside 
the box)

The tops of ICs were all over the guts of every printer, terminal and the 
computer let out the magic smoke.  ALL of the terminals and printers had been 
unplugged - but not from the RS232 connections.

The ONLY way to isolate the rig is totally unplug the thing: antennas, power 
supplies and so on... same with your computers.  

Down in Florida, there are code required surge MOV's in every circuit breaker 
panel.  All they do is eliminate something close by.  They get vaporized by a 
direct hit.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Bill Blomgren (kk4qdz) via Elecraft]

The question is how long are they?  - Ethernet cables are typically 6-20 feet 
long.  A jumper between the rig and amplifier, much shorter.

Length determines how well it acts as an antenna.  The cables I worked with 
were perhaps 20-50 feet long, and made good antennas.  Some of the ethernet 
cables in my apartment are 50 feet long to feed from one extreme to the other. 
(I do video editing and need at least gigabit end to end...)

Telephone cables will be LONG.  Unplug anything connected to dsl or phone lines 
in general.

Luckily, the apartment I'm in has underground utilities.. However, that nice 
shot of a tower on the ground getting a direct strike was interesting.

It shows that having a few high trees around that are much higher than the 
antenna are NOT a reason to not disconnect. 


Lightning looks for an interesting way to ground.  Don't encourage it by 
leaving lots of paths in the shack available.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Bill Blomgren (kk4qdz) via Elecraft]

As a side issue - one of the stations down in tampa ended up off the air for a 
week.  A lightning strike melted their heliax and antenna system was destroyed. 
 The antenna was on the top of a bank building (about 70 stories up.)-- using 
the building frame as ground, and then in the ground under the bank building.

The transmitter, luckily, was not destroyed. (significant damage of course)  
However depending on where you are, and the strength of the strike... all bets 
are off.  One station I helped put on the air (which had -2- layers of copper 
plates in the trench between the transmitter shack and the studio with the 
trench under ground had the entire rectifier stack in a Collins FM transmitter 
melted, assorted other stuff there... the lightning then hopped into the trench 
(on the ground) - and destroyed all the monitoring gear in the rack where it 
terminated.


.Of course, that is Florida, where lightning tends to be 2-5 times stronger 
than other spots in the country.

The alternative to disconnecting everything is to design your ham 
station to tolerate lightning events.
There was a very good 3 part series in QST for June, July and August of 
2002 that dealt with the design of a station for lightning protection.  
Those articles are available at 
http://www.arrl.org/lightning-protection.  I highly recommend it.

Some of the ground rules given in the article:
All towers and masts grounded with buried radial wires and ground rods 
to spread the impact of a strike over a large area of the earth.
Perimeter ground wires around any building with a driven ground rod at 
each place the wire changes direction. (lightning likes to travel in a 
straight line).
Bring all services into the ham shack through a common grounded copper 
panel fitted with suppression devices - that includes feedlines, power, 
CAT5 cables, phone cables, and everything else.
Keep any equipment or devices that are not powered/connected through the 
above panel out of reach of the operating position.

There is no guarantee that the above steps will eliminate failures due 
to lightning, but it will go a long way toward achieving that goal.  The 
real goal is to keep *everything* in the shack at the same potential 
during a lightning event.

I have attempted to use those guidelines in the construction of my shack 
and antenna field.  All my feedlines are automatically grounded when the 
station is turned off, and I do not attempt to operate when there is 
lightning nearby - and I get stay out of the shack during storms.
We had a lightning event here last year that took out the Ethernet 
router, several switches, 3 computers and 2 network attached printers.  
None of the ham gear was damaged.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

Those look exactly like what we had 3 of in the circuit breaker cabinet in the 
house and condo in St Pete.  A really direct hit will blow them up, but 
hopefully after they have sunk most of the energy.  One big snap, and they are 
done.

Then again, there are more joules in a lightning strike there than they can 
handle. Lets face it.. the Lightning lab that was set up north of Daytona had 
6-10 foot long glass sculptures under the tower they put up there... Anything 
that can turn that much sand molten is more energy than a MOV can manage to 
make go away easily... Rather stunning forms in various colors in the 'brown' 
areas of the spectrum... You can see how the lightning bolt spread after 
getting into the sand.

There is some protection to AC surges, look here:

I have one on my service entrance.  Does it work?  I can't prove that, but

There may have been more that I'm unaware of. I'd like to think it worked here

It boils down to risk assessment too.  That is a personal decision. I've got 50

Sticking to 6 meters, you might have a chance.  Antennas will be over a meter 
tall, and a ground plane will be a problem.
 
That said, my experiences with 11 meters was 'iffy' --- even with a huge 
antenna on a large spring.  (Having to ride through a florida thunderstorm, you 
really don't want a pointy metalic object trying to attract millions of volts 
and hundreds of thousands of amps, so in rain in Fla, the antenna was bent over 
under my arm and hooked under a hook on the motor guards to keep it out of the 
way of lightning...)
 
Then again, that was back in the dark ages of the first year of the 'wing, when 
it was a 1000 cc 4 cyl, and had no reverse or wet bar

Well, there is no reply all, just reply, and I am replying to the mailing
list, so I don't know what else I can do.

And yes, it is going to require an investment for everyone to go to 6m.
But... the serious HAMs that have helped provide this solution already run
6m, and the cost is rather incremental if you are riding a $30K Goldwing,
K1600 or HD bike.
Even on my F700GS, we are talking my cost in tires every year to buy this
radio and a 6Db antenna.

So, please, don't add limitations I have not stated.

Now, someone stated somewhere that 6m is hard to keep attenuated, and that
might be a deal killer. Maybe 10w vas 5w is not worth the gain. Maybe 25w is
the floor.

Again, with all the praise for this unit, it seems odd it is such a wall
flower. *shrug*

When I talked to the techs at the office, they seemed to think it would be
ok, but then they are selling it, they are not going to say it can't do the
job unless it is going to damage their rep if it breaks.

Considering the almost 100% against, I think most people's reaction to a
bad review if it failed on a MC would be dumbass

Re: [Elecraft] OT: application of directional Quad in UHF

[Bill Blomgren (kk4qdz)]

A friend (who is a mechanic at heart) threw together a 4 element quad for 2 
meters, along with a moxon for 2 meter sat work.  The feed for the 4 element 
quad is *straight* coax.  To an ugly balun below the antenna.. It feeds at 50 
ohm rather nicely. And easy to build.  (Spreaders are just fiberglass driveway 
markers...wire simple 12 gauge wire. It has survived 3 ice storms, and a near 
miss by a tornado.
 
Superb directionality and all that.  About a 3-4' long piece of pvc for the 
central beam that holds everything.  Portable. And lots of gain.
 
The moxon gets used with his hand held for sat comm work.  In front of the 
moxon, a 5 or 6 element yagi for 440. 
 
Next experiment for him? I've heard he is working on a quagi.  That is a quad 
reflector, quad driven element.. then a boat load of directors made up of 
copper wire on a piece of light wood.  More gain than a 6 element quad... and 
lighter.

Johnny...
I have no experience with UHF quads, but I modeled, used and modified an
HF quad for over 15 years. I now use a SkyHawk HF triband yagi. Based on
that experience, quads require more mechanical effort for construction
and maintenance. The form factor for a yagi is two-dimensional, while 
for a quad it is three-dimensional. Thus, packing, storage and transport 
is potentially simpler for the yagi than for the quad. Feeding a yagi is 
simpler than for a quad, because the yagi can use a solid driven 
element, while the quad generally requires a break in the driven 
element; this can complicate construction. Adding elements to a yagi 
antenna is mechanically simpler than adding elements to a quad. So, 
based on my HF experience - and thinking about UHF quads - I think 
mechanical issues might be a significant difference. At UHF a 4/5 
element yagi might be easier to deal with than a 3-el quad. My opinion.

[Elecraft] Snap crackle and pop

[Bill Blomgren (kk4qdz)]

You may want to use a divide and conquer operation.
 
Test on the local lan... plugged into ethernet locally.  If everything is clean 
there, it is outside the K3 and the local lan.
 
Lots of ISPs tend to throttle users of bandwidth that they consider excessive 
- Time warner runs ALL the traffic on HTTP to You Tube, and cuts it back to 
almost dial up speed. They have a proxy server array that they run it through.  
You Tube decided to go to HTTPS because you can't proxy that without breaking 
the certificate chain. 
 
The only way to get decent performance here is use the SSL connections.  (I do 
a lot of video for non profits...and see the terrible results at the tube...
 
They also like to drop packets from time to time when routers get saturated.  
At one point, one of the metro area rings was dropping 40-50% of the packets 
going into it.  (MAE west and MAE east were both grossly overloaded for many 
months, with the result there was a lot of traffic that went in the black hole. 
 (They have since upgraded, and I have not done any testing in the last 9 
years.)
 
Try it on local lan.. then on local (neighborhood) network.. see where it 
breaks.

I think Chris summarizes the issue pretty good.

Gary, it kind sounds like you have not taken the time necessary to 
really get familiar with your K3 (excuse me if this is incorrect).  I 
found it took me about three weeks of playing and reading the manual 
until I became fairly comfortable with using the features (only 
some, not all) of the K3.  The Fred Caty manual had not been written 
so this was a little more difficult on some topics and features, but 
I figured them out with a little time tinkering and reading.  This 
list is a great resource of knowledge, too!

The K3 does require more time to become versed in its abilities and 
that can try one's patience if just wanting to plug n play.  I 
bought my K3/10 as a kit so had that process before even turning it on.

So take it out of the box and connect an antenna, with hopefully 
Fred's manual at hand, just step thru the pages of the manual and try 
some of the stuff he writes.  Great way to get more familiar with the 
radio.  You might want to skip some chapters if not particular to 
your interests.  Give the radio some time and do compare it on the 
air with the TS-590.  I haven't had my hands on the TS-590 but I 
suspect you will develop an appreciation for the K3.

When I chose the K3 it was after several years of studying the 
literature and comments.  I came from having a TS-180 in 1980, TenTec 
505 Argonaut, TS-50, FT-840 (liked that one), and FT-847 (great 
VHF/UHF but disappointing on HF).  I also acquired the FT-817 when it came out.

Being active in eme on VHF+, I needed a good CW radio and a 
transverter friendly radio and that brought me to the K3/10.  The 
fact that is a SDR means I do not have to shell out more money every 
2-3 years for the latest advances in radio technology (so far this 
has been true).  I sold my FT-847 to raise cash for a 222 and 432 
transverter and finally sold the FT-817 in favor of the KX3.  With 
addition of the 2M module the KX3 will have pretty much replaced what 
I used with the FT-817.

To purchase my K3 I had to promise my wife that this would be the 
last big ham purchase in my life as we entered retirement (and 
reduced income).  Yeah, I lied, but she understands 
(thankfully).  But I can say the K3 is fulfilling that promise since 
buying it four years ago.  Elecraft is unique in providing equipment 
support and upgrades (via firmware).  And upgrading is purely 
voluntary on your part, so you do not have to if not interested.

Finally, there is a lot of new stuff going on in ham radio if you 
look, so if the same old stuff' has gotten boring, take a look at 
some of the digital modes, soundcard programs, come up to VHF/mw or 
down to MW and LF.  Try building some stuff - can be fun!  Get out of 
the house and go portable/mobile.  You get the idea.

Gary, come back in a few weeks and tells how it goes!

Gary,

Take time out, study the manual learn to embrace the modern features and
play, play and play some more
to learn your way around. You have taken the tests, passed the exams etc so
practice what has been preached.

Get rid of the big rice box, keep the TS590s (best value on the ham market
today) for back up or field day.

Then just fall in love with your K3 - simples.

Re: [Elecraft] Elecraft SSB Net results, September 8

[Bill Blomgren (kk4qdz)]

This last Sunday, I think Netcontrol didn't come down anywhere near me.  (The 
Raleigh NC area)


Just a few hz away there was the marine net on 14.300 that was booming in from 
Texas. - NO problem hearing them.. but 14.3035? Nope. Nothing.

There was traffic up at 14.305 something.. so I know the antenna was working.. 
just not catching Atanta...(I was probably where he was hitting the 
ionosphere..)

N7SP etal:

If I may make a suggestion that might make KX3 checkin easier.  On 
other nets that I often check into, the first stations invited to 
checkin are portable, mobile, and low power stations.  That gives 
those stations a better chance of avoiding being covered up by 
stronger stations.  Not sure if this could be incorporated to the 
Elecraft-SSB net protocol?

I have checked in with my KX3 sn475 several times and usually I wait 
till the near the end of the net when the dust settles a bit.  I do 
have the advantage of a yagi at 50-feet.  I also checked in with my 
K3/10 sn4340 barefoot many times before I had an amplifier (I have 
both 120w and 250w amps).

I will try checking in this Sunday with 250w.  Past couple weeks prop

Re: [Elecraft] Wounded Warrior - Ham Operator

I wonder if this would be a good 'fund raiser' for Hamfests.  There are a bunch 
of wounded warriors here in NC fighting their battles with the VA.
 
One of the local veteranarians has setup a pets for vets to help some of the 
folk with PTSD.  (Having a dog that loves you unconditionally, and helps give a 
reason to get out of bed is a GREAT thing for some of them...) -- I suspect a 
bunch would find ham radio a great way to pass the time while healing.

 I would like to thank  John  KF7OM  for being patient while a bunch

 I would like to thank Don Wilhelm  W3FPR for his help trouble 
 shooting and
 walking me through a trouble shooting of a donated kio2 kit that did not
 work. Don you assistance was right on and you hit the nail on the 
 head and
 solved the problem.

 I would also like to thank the fine people at Elecraft. Once Don had
 isolated the problem and it was a transistor. I called Elecraft and 
 spoke
 with Howard. I explained that Don and I had been trouble shooting a 
 KIO2 for
 a Wounded Warrior new ham and needed a transistor. I gave him a part 
 number
 and Howard said I will get it sent out to you tomorrow. It arrived 
 fast and
 resolved the problem.

 The radio was given to the Wounded Warrior today and he was beaming with
 pride. A bunch of local hams came out and built a dipole antenna and 
 pitched
 in to get him on the air.

 When he found out that John, Don, Howard from Elecraft had all help a 
 person
 they did not know it brought a tear to his eyes. For a Wounded 
 Warrior who
 also suffers from PTSD. Ham radio allows him to met new people and talk
 around the world. Right now he has a Elecraft K2/10, we are all going to
 work on getting him a mic and eventually up to a 100 watts. But he 
 showed
 great interest in qrp. The mic will not be used much I suspect as he has
 also expressed a great interest to do CW.

 So, Thanks to all of you that help in this project. It reassured me that
 hams are great people and that Elecraft is the very best in customer
 service. I know that most the hams down here could not believe that 
 Elecraft
 would send the part out and that it was so easy to get ahold of a
 knowledgeable person from the company. I can assure you that the Wounded
 Warrior will not buy any other brand of rig, except Elecraft.

 Thank you all. It was very touching.

Band conditions here were also dreadful.  I tried the same process. I could 
occasionally hear some voice like artifacts in the noise, but the noise was s8 
and s9 solidly for the first 30-45 minutes.  I tried calling for a relay, but 
heard nobody.  Noise here was horrible.  Earlier in the morning I worked a guy

Re: [Elecraft] Elecraft SSB net announcement

[Bill Blomgren (kk4qdz)]

With my antenna roughly perpendicular to where the signal needs to get to the 
net, I could hear occasional snippets, but not enough there to listen to.  I 
need to rotate the antenna about 90 degrees to make a difference.  (Perhaps 
next week.) - There was a fair bit of activity at 2-3 on 20, so I suspect the 
dipole is my problem.  (I checked with a couple of others in the general area, 
and they could hear the net nicely.. but with S9 noise, all I could hear was 
just a few snippets of call signs.  sigh

However.. NEXT week (with luck) I'll be roughly perpendicular to the current 
orientation if I can get something over another tree limb.

Re: [Elecraft] KX3 - buy without KXAT3?

[Bill Blomgren (kk4qdz)]

This evening I added a gator clip equipped chunk of line to the KX, and had it 
grab hold of the downspout on the gutter, and about 50 feet of line spread over 
the ground
 
End result: could get a 1.1:1 match on 40 and 20.. 10, 1.5:1... 160 wouldn't 
tume effectivly.   Then again, it is about 100 feet to 120 feet of gutter, 
which is a tad off for 160 meters
 
The results: tried to get into a SSB conversation, but was apparently drowed 
out by the guys running 1kw... but who cares.. I'll make a contact one of these 
days...

I have to say I have actually matched a mop bucket with my kx3 with internal
tuner! :)  It is bar none the best tuner I have used.

Re: [Elecraft] Problem on the first weekend...

[Bill Blomgren (kk4qdz)]

I'm not sure which part of what I did managed to make the machine confused 
enough to lose the bias setting...
 
Had I known ahead of time that the error indicated that I would have just run 
that calibration .. but did whatever caused that problem step on other 
calibration  data?

Also the KX3 has to be powered by a power supply and not the internal batteries 
for the TX Gain to calibrate.

Glad you're making headway.

I had no problems with kit number 21.

The book said set it to 4 watts (exactly) - so I did that.
 
The problem was that the transmit bias values were apparently lost somewhere 
along the line.  Why? No idea.   
 
I did the transmit bias adjustment procedure, then the transmit gain worked 
perfectly.  Now the problem of finding a local with a spectrum analyzer to 
reset the filtering on SSB.  sigh

Bill,

If its a KX3 you're dealing with, make sure the power is set to 10 watts 
output before doing the TX gain calibration.

 I went into the menu system, and noticed that the ATU setting was set to 
 not installed - which wasn't the case.  Set that to auto... and then 
 things went downhill.
  
 I tried to do a atu operation, and the system told me that there was a 
 problem with transmitter calibration.  I built the dummy load I bought with 
 the radio, checked that, and it was a nice 50 ohm load.  Plugged that in and 
 attempted to do the power calibration... and got an error...  Doing the same 
 thing via the computer today.. same error.
  
 The system failed to reach the expected power level on 1.9 mh.
  
 Before even considering transmitting with the rig, I had dialed the power 
 down to 0, but that didn't seem to impact the tuner at all.
  
 Now, I get a d= 
 err txc  and when I tap the tune button I get 
  
 err tx5
  
 I did a reset (power on plus the PBT pressed.) -- Reset the atu setting to 
 bypassed.  went and tried the tune again, and got the same errors.
  
 Has anyone seen that in the past?  I hate to think something died before I 
 could even transmit.  sigh

[Elecraft] YEEE HAA!

[Bill Blomgren (kk4qdz)]

The UPS tracker changed about an hour ago..

rebel yell  YEEE HAAA!  /rebel yell

The shipment arrived about 120 miles east of me today... It will make it to the 
RDU area tonight.. and be out for delivery tomorrow.

Makes me wonder if UPS shipped it cross country on truck, or if it went by 
rail..
