Hello Ed,

I would caution you against trying your K3 in those temps.  Minus 60 
degrees F. is the coldest on record for Minnesota, and you experience 
far colder that that. The cold may do multiple things to the K3 if it 
has multi-layer circuit boards.  I didn't notice if it does.

Our club left a repeater in an unheated enclosure one winter. I would 
estimate it wasn't much colder than minus 30 degrees F. at that 
location. (To clarify for others, this is 30 degrees F. below zero.)  I 
have seen what the multi-layer circuit board looked like. More 
specifically, the thru-the-hole solder connections from one layer to 
another were cracked. Maybe it was the type of solder used???

I'm sure circuit designs have changed since the first solid state rigs I 
described in the cold.  LCD screens hadn't been heard of yet.  I'm 
surprised they don't freeze and get damaged in your temps.  It is 
interesting to read of your outdoor experiences.

73,
   Dick, n0ce

Do you mean there's just a power cord plugged into the outlet, and the 
other end connected to nothing?  If that's the case, I'd suspect arcing 
at the plug at one end of the cord, in which case you should replace 
that cord immediately, before it starts a fire.  The only other 
possibility I can think of is that the wiring to the wall socket is in 
conduit, so it's shielded, and the line cord is acting as an antenna, 
radiating whatever junk is on the wiring.  (Be sure to turn off all the 
fluorescent lights nearby.)

That's a good start.


Any ideas??


Describe the antenna that you're listening to when this happens. How far 
from the shack?  If it's any sort of end fed antenna, what is your 
counterpoise?


Is this the "standard" line cord that came with the KPA500?  Is the KPA 
wired for 120V or 240V? Are you sure the plug is correctly wired?  For 
240V, the two "hot" wires must go between the two legs of 240V, the 
equipment ground (green wire) must go to the green wire at the outlet, 
and there must be NO connection to neutral.  For 120V, the transformer 
must be wired to phase (120V hot) and neutral, the the equipment ground 
must go to the green wire at the outlet, and there must be no connection 
between neutral and the green wire.



I have a ground bar that all of the radios are attached to.  Single ground wire 
to an 8 ft ground rod just outside the shack. Hm!  (me scratching my head)


Is that ground rod bonded to all other grounds in your home/building?  
It MUST be. Is there a good ground (driven rod) at the service entrance?

Re: [Elecraft] Cold K3

[Edward R Cole]

I've not tried running my K3 at outside temps, but many years ago had 
opportunity to test my TS-180S in the cold.
I was going out to a remote checkpoint on the Alaska Iditarod Trail 
(sled dog race to Nome) and my radio stuff did not make the load from 
one bush town to another so the box with radio sat outside in the 
snow overnight.


When we arrived at the checkpoint which consisted of a wall tent at 
the edge of a frozen lake, I checked the big round temperature dial 
put up on a post (it read from -60 to +100F) and the needle say on 
minimum (-60F).  It stayed there for three days so we had no idea how 
cold it got at night.  Snow was three feet deep requiring one to wear 
snowshoes everywhere.


The interior of the tent was warmed by a wood stove (55-gal oil drum 
converted to stove) to -15F.  When I got my station first set up the 
LCD screen did not work (too cold) so I left it turned off to warm up 
a little.  It worked fine then at -15F inside temp for the rest of the time.


The Honda 800w lunch box generator would not budge when the starting 
rope was pulled...until we sat the generator on top of the stove for 
an hour to warm up the lubricating oil enough to turn over the 
engine.   Ran fine once warmed and I did not stop it except for a few 
hours at night while we slept (wore my insulated underwear inside the 
down sleeping bag with my down parka draped over (like a cocoon).


Third day it warmed up to +15F and we were walking around outside in 
our tee shirts it was "so hot".  A day later arriving back in 
Anchorage where it was +30F the sweat poured off me just wearing my 
wool shirt and jeans outside.

March-1986.

I am installing my KX3 in my truck so curious if it will have any 
issues when cold.  Its easy to disconnect and bring into a warm house 
or trailer so maybe will not have to face that.

Re: [Elecraft] Camping radio ops: then and now

[Ron D'Eau Claire]

My first was in the summer of 1954 in the Mojave Desert near a place called
"Giant Rock", actually an Air Force emergency landing strip where Flying
Saucer enthusiasts gathered for meetings, calling it the "Giant Rock
Interplanetary Airport" although I never say any extra-terrestrial visitors.


My buddy John (also a Ham) borrowed his family's Willis station wagon and
built up a motor generator set with a small gas engine driving two 115 VAC,
400 Hz surplus aircraft generators. We had a national receiver and a Babcock
and Wilcox CW/AM transmitter running a single 2E26 in the final so, I
suspect about 30 watts d.c. input. No trees in the desert, so we had two 30
foot masts made out of pipe and lots of guy wires. 

It was more of an adventure setting up and getting on the air than actually
making contacts, but a fun 3 days in the desert. We slept on the ground and
perhaps the most memorable part of it was waking up one morning, crawling
out of my sleeping bag and when I went to roll it up I discovered that a
rattlesnake had crawled in with me to keep warm during the cold night.
Fortunately he was still pretty cold and lethargic and so it was easy to
extract him and send him on his way after a few minutes in the morning sun.
It has henceforth known as the Great Rattlesnake Expedition.

Hello, 

Here is how I make loops...  I had a friend bend a nice loop out of
large diameter electrical conduit into a three foot circle, offsetting
the ends by one inch where they would come together. 

I then feed the copper tube into one end of the conduit, and force it
through the conduit by hand.  As I said, the ends of the conduit are
offset from each other by about an inch, so when the copper comes out of
the other end, I just pull the loop out...  

Poof, one finished loop, no sharp bends, and I can make loops all day,
each one exactly the same as the first.

Re: [Elecraft] [OT] Tube Bender for Mag Loop antenna?

[Don Wilhelm]

Yes, muffler shops (especially the independent ones) are likely to be 
willing to do the bending for you.  They have dies for most any size pipe.


They are also a good resource for small welding jobs - it is usually 
best to approach them when they are not too busy.

Re: [Elecraft] Mag loop bender

[Mel Farrer via Elecraft]

OK,  enough,
If you don't want any kinks in it.  You should slowly fill the tube with DRY 
sand and tap it until it it is packed full THEN proceed with the bending.    IF 
you have packed the sand tightly the bend will resist kinking.  I have used 
this for bending tubing over a pulley with good results.  The pulley for the 
bend radius you need should to be progressive from large to final. For me it 
took three sizes to get to the final radius without kinks.  Works with aluminum 
and copper.  Does not work on conduit.

Re: [Elecraft] Camping radio ops: then and now

[K9MA]

Hi John,

Links to regulator and tuner schematics:

http://sdellington.us/hr/KX-1_regulator4.pdf

http://sdellington.us/hr/EFHW_Tuner2.pdf

 A couple notes:

I had some trouble with the LT1965 regulator oscillating, probably due 
to the lead inductance of the leaded (non-smt) capacitor I used, hence 
the LC network.  The MIC29150 regulator data sheet claims it works with 
all capacitors, though I haven't tried it. If the MIC29150 is used, the 
LC network is replaced with a short. The way I wired the regulator to 
the KX1 required cutting a trace on the PWB, so the power could be 
switched ahead of the regulator.  This prevents the regulator from 
discharging  the battery when the KX1 is off.  If you prefer not to cut 
the trace, you could wire the batteries to the regulator input through a 
connector, and just unplug that connector when you're not using the KX1.


The tuner is based on the Pacific Antenna BLT+, using most of the same 
parts.  I bought the BLT+ kit without the case, replaced the 
transformer, and put it in my own box.  The kit includes the N7VE SWR 
bridge.  Note that my version is only intended to match end fed half 
wave multiples, with impedances from about 1,000 to 6,000 Ohms, and it's 
strictly QRP.

Re: [Elecraft] Camping radio ops: then and now

[Dave KW4M]

Not counting Field Day outings with the local club, my first camping radio
excursions were with a Heathkit HW-104 powered from a gel-cell battery about
the same size as a car battery.  Needless to say, I didn't set up camp too
far away from the car!  But it was rather nice to have a battery-powered
all-solid-state rig without needing a step-up switching supply for a tube
radio.

A few years later I homebrewed a transceiver with camping as a primary goal,
see  here.    
This was a major step forward in convenience with a high fun factor.

Now I usually just carry along the KX2 in a small pack.  The antenna varies,
but most often I use a 20 meter inverted V suspended from a cord tossed up
into a tree.

Dave

It will probably be an amusing break from the day-to-day to make an antenna.

For smaller gauge loops, thin-wall flexible copper tubing is nice. The kind of 
stuff you hook up a fridge ice maker with. Hammer the end flat, drill a hole, 
and screw it down.

Re: [Elecraft] Camping radio ops: then and now

[Bill Frantz]

On my first portable operation, I put my Small Wonders Labs 
PSK-20 (a 20M 5W transceiver fixed tuned to the PSK subband), a 
MacBook, a SignaLink, a battery, a dipole, and a Thermarester 
portable chair into a backpack and hiked about a mile up into 
the Sierra Azul open space district above Los Gatos, CA.


I found a lovely site overlooking the valley with trees giving 
me about 15' elevation for the dipole. I had a fun afternoon 
making PSK contacts.

[Elecraft] [OT] Tube Bender for Mag Loop antenna?

[rick jones via Elecraft]

I'm fabricating a remotely tuned magnetic loop antenna. I have the vacuum cap 
and stepping motor tuning system built and ready for a loop. Do any of you 
guys/gals especially in 3-land have a rolling tube bender so I can make my 3 
foot copper loop? I don't want to hand-bend soft copper and would rather not 
buy a bender for such limited use. I could possibly build a light duty one but 
U-channel pulleys that will accommodate a 1.1" OD copper pipe are impossible to 
find online or even on eBay. If any one reading this knows someone in the Mid 
Atlantic area who can roll a hoop, or can recommend a source for  >1.1" nylon 
U-channel pulleys, I'd appreciate it if you could contact me off list. Thanks 
for your time. PS I don't want to sweat solder an octagon. I'm trying to keep 
loop R to an absolute minimum.

Re: [Elecraft] Camping radio ops: then and now

[Mike Flowers]

My first real portable operation wasn't really camping at all.   I was on
Maui at a condo with a switching power supply, an IC-7000 and a 20M dipole.
My wife would bring me out cold Coronas and I had a blast working my buddies
on the mainland as KH6/K6MKF.

Mine was from the Blue Mountains in NW Oregon in 
1955. ARC-V gear powered via a dynamotor.

​For me, portable operations went from a rare, scheduled event requiring a
team of people and equipment to a small Nikon camera bag that fits in a
corner of a bag on my motorcycle. In other words, it went from a chore to a
joy.

Re: [Elecraft] [KX3] Camping radio ops: then and now

[Alan]

Other than Field Day, my first true portable operation was one summer 
around 1970 when I spent summer vacation working as a waiter in a Swiss 
hotel.  I got a callsign (HB9XVK if I remember right) and took along an 
all-homebrew CW station.  The receiver was a transistorized direct 
conversion type and the transmitter was an "AC-DC" type:  it ran 
directly off 120VAC with no transformer.  The tube filaments were wired 
in series (I think the lineup was two 50C5s and a 12AU7 or something 
like that) and the high voltage was rectified directly from the AC line. 
 Of course I had to use an autotransformer to make it work with 
European 240VAC.


Then the hotel put me in a basement room where the window looked out 
onto a patio, so I wasn't able to put up a decent antenna.  I think I 
only made two or three contacts.

For what it's worth, here's my recent solution for bicycle portable

It weighs a bit more than Wayne's station, but I don't need trees to 
hold the antenna up.

[Elecraft] Any news on Controlled Envelope SSB for Elecraft rigs?

Hi guys,
   after some time, I was wondering if any news are available on the
Controlled Envelope SSB for Elecraft rigs. Maybe is it on the wishlist?

For sure it would be a great improvement for K3 (and KX3) in many
environments (contesting for sure!)

Thanks,

This is not a Tascam (sound card) issue.  The solution to this ha been

it ...

1) close WinWarbler
2) Using Windows Explorer navigate to the DXLabSuite\WinWarbler

I understand officially the Tascam drivers ended with WinXP/Vista, but I had
it working in Win7. I've tried using the Compatibility feature in Programs
under Control Panel to no avail; the Tascam driver software seems to load
but results are the same--no TX.

I have verified VOX is engaged and the VOX gain set properly. This whole
setup worked fine until today. I think there was an auto-update for Win10
that installed since the last successful operation and suspect that killed
the Tascam.

Any ideas on how to jump start the Tascam into action? Or is it time to
retire this piece of gear and get something else? Tnx!

Re: [Elecraft] Tascam 122 and Windows 10

[K9IR]

Quick update--it appears the issue may be between MMTTY and WinWarbler. In
further t-shooting I was able to send from within MMTTY, so the sound card
appears to be alive and well under Win10. I've emailed Dave/DXLab with my WW
error log.

Sorry for the bandwidth. I'd learned about using the Tascam as a sound card
on this list and thought there might be some advice for making it work under
Win10 (which now appears to not be the problem).

[Elecraft] Tascam 122 and Windows 10

[K9IR]

I have been using a Tascam 122 MKii as an outboard sound card with my K3 for
RTTY. Initially the Tascam worked fine after upgrading the shack PC to
Win10. Today, however, while I can decode RTTY, I cannot send any longer. I
get an eZeroDivide error message from MMTTY when WinWarbler starts.

I understand officially the Tascam drivers ended with WinXP/Vista, but I had
it working in Win7. I've tried using the Compatibility feature in Programs
under Control Panel to no avail; the Tascam driver software seems to load
but results are the same--no TX.

I have verified VOX is engaged and the VOX gain set properly. This whole
setup worked fine until today. I think there was an auto-update for Win10
that installed since the last successful operation and suspect that killed
the Tascam.

Any ideas on how to jump start the Tascam into action? Or is it time to
retire this piece of gear and get something else? Tnx!
