160 on the K2

William E. Twaddell
I would like to hear some comentary about addimg 160 to my K2.
I have never worked 160 because of the severe antenna requirements.
What does the reflector think?
tnx

I'm with you, Bill. My antenna limitations make working 160 impractical at
this QTH, although it can always be done. Shoot, I know a lot of guys who
have run 160 mobile in motion with a whip no more that 10 or so feet long.
(Actually, the more successful ones of the '50s ran a long whip tied to the
rear bumper looped over and tied to the front bumper to form a loop with the
car body, but they were still very small antennas.

Even so, the most useful feature of my 160 module is the second receive
antenna. It lets me mess with small tuned loops, active antennas, etc., as
an option to the main antenna for receive. That can be a real plus when
dealing with severe antenna restrictions in which the best transmitting
might not be the best receiving antenna.

Re: 160 on the K2

I used to run 160 many years ago off of a Butternut HF6V when I was  
QRO. I did not make a whole lot of contacts on it, but it was fun. It  
*is* a different animal.

I am currently adding 160 to K2 #1981 (along with a ton of other  
things). I doubt I will do much there, but it will be there just in  
case I ever want to.

Anyway, the antenna requirements are not that bad. Yes, if you want  
to do it "the right way" it is. But to play on you can build a cheap  
vertical out of some tubing and make a few contacts and it won't take  
up all that much room.

I was also of the impression that the guys on 160 would go a little  
farther to try to make a contact - that is, they will listen more.  
That's just the thing for QRP.

I was first licensed as G3UTY in 1964.
My first rugs were home brew, 2 tube Rx and 2 tube Tx  on
"Top Band" (1.8 Mhz).
We used to run mobile using a center loaded 8 ft whip
attached to the rear bumper.
I could work a lot of europe with that configuration...

You don't know what you can do until you try :-)

Interesting words from another domain -- K2 presentation

Margaret Leber
In reply to this post by William E. Twaddell
I was reading my daily RSS feed and happened to encounter the following.
While the author isn't an operator (to my knowlege), I was struck by the
strong resonance with the *craft* part of "Elecraft". So many of these
points apply to the Elecraft experience that I though I'd share it with
you folks.

---------------------------------------------------------------------

  Draft Craft Manifesto

I’ve been trying to pin down what is driving the increasing popularity
of crafting for a while now. This is what I’ve got so far:

1. People get satisfaction for being able to create/craft things because
they can see themselves in the objects they make. This is not possible
in purchased products.

2. The things that people have made themselves have magic powers. They
have hidden meanings that other people can’t see.

3. The things people make they usually want to keep and update. Crafting
is not against consumption. It is against throwing things away.

4. People seek recognition for the things they have made. Primarily it
comes from their friends and family. This manifests as an economy of gifts.

5. People who believe they are producing genuinely cool things seek
broader exposure for their products. This creates opportunities for
alternative publishing channels.

6. Work inspires work. Seeing what other people have made generates new
ideas and designs.

7. Essential for crafting are tools, which are accessible, portable, and
easy to learn.

8. Materials become important. Knowledge of what they are made of and
where to get them becomes essential.

9. Recipes become important. The ability to create and distribute
interesting recipes becomes valuable.

10. Learning techniques brings people together. This creates online and
offline communities of practice.

11. Craft-oriented people seek opportunities to discover interesting
things and meet their makers. This creates marketplaces.

12. At the bottom, crafting is a form of play.

By the way, next Wednesday I'll be doing a presentation at the Phil-Mont
Mobile Radio club meeting on my K2 experience. Folks who are in the
Philadelphia area that evening who might like to attend can contact me
for information.

I have not put the 160m module in my K2 but I do have some experience in  
operating QRP on 160m from my antenna restricted QTH. I found that the feedline  
run I placed in my house from basement to attic (when the house was being  
framed) will tune up with my external Z11 ATU on 160m and I run my FT-817 at 5w  
on that band. I only can make contacts during the contests and the majority of
 those are with stations with very large antennas. Still, a lot of fun doing
more  with less.

Re: 160 on the K2

Mark J. Schreiner
In reply to this post by William E. Twaddell
Well, the kit sure doesn't cost too much extra to add and you get to
solder some more, so those are a couple of benefits right off.  The
separate Rx port was also intriguing to me and while I haven't used it
yet on my fairly new K2 I would be interested in trying it with a
magnetically shielded loop or someday when I have more space again some
Beverages.

I wouldn't say that I am currently antenna limited, though, as I do have
a Carolina Windom 160 up about 40 to 45 feet.  It has worked quite
well.  I've always found that even with 100W on 160m I felt like I was
QRP as so many folk are running KW+ on the top band.  I've been told not
to bother with 160m when I was trying to answer somebody's CQ (he was
running a KW and I had my standard 100W) and he couldn't hear me very
well.  I mean, some folk there are just plain rude, maybe not as rude as
some on 75m or so on but sure enough, rudeness isn't limited anywhere
that I've found.  With all of that "bad experience" I still decided to
install the 160m module.

I figured maybe at least I can listen.  Well, my first night out with it
I tried it out on Tx as well, just 5W CW.  Have worked several states so
far, almost every time I've spend a few minutes calling CQ on 1810 kHz
somebody comes back to me (usually running nearly 100W).  Had a nice
2x599 QSO with a guy in Alexandria, Virginia last night (I live in
Allentown, PA, so no great shakes, but was nice anyway).  My favorite
QSO of all so far was with a station in Greece!  I could only give him a
559 even though he was running about 800W I think, but he gave me a
569!  How did he do that?  His Rx was with a 1000' long Beverage (one of
four) pointed at USA.  Also, he claimed band conditions were quite good
that night.  I'll tell you, if you made just one contact like that it
would be worth the price and effort to install!  Every time I make a QSO
on 160m while QRP I'm always amazed.

Also, with a compromised antenna situation when I was a kid living in
Michigan in the mid-80s one night I heard a big pileup on the Marshall
Islands.  Well, I didn't bother trying to bust the pileup running 100W
and a poor antenna, but I tuned around a bit figuring maybe other
stations from that area would be active as well and maybe easier to get
since there were so many stations in the pileup.  I was right!  First
worked KH6VT in Hawaii, got him on about the 2nd or 3rd call.  Then I
heard a station that I had no idea where they were but I remembered the
advice from my Elmer "Work 'em first, worry about 'em later."  The
callsign was UV1OO.  Turns out they were on Franz Josef Land in the
Arctic Sea.  Imagine, the band being open to the Pacific and completely
opposite direction to the Arctic areas as well, simultaneously!  Rather
than tuning around to see what else I might find I just shut the rig
down and went to bed happy that night!

160 is truly amazing, give it a shot.

Re: 160 on the K2

William,
 
Come join the fun at 160 and it is not all that daunting to get on the air.  I use an Inverted-L antenna that is 130 feet long...about 60 foot up the tower and then 70 feet to a tree.  The horizontal leg is sloping down quite a bit and it works well.  Now, I am not working DX on the first call, but I've done plenty of damage with the antenna in 160 meter contest state-side.
 
Although it is called an Inverted-L...and 130 foot length of wire is going to tune somewhere with a little ham radio engineering.  The thing you need is a counterpoise or radials on the ground.  The more the better (to a point).  I have 17 radials...random length that fits on my city lot...in a half-moon because my house is on the lot and I have not taken the time to snake radials under the house and around the basement.
 
The K2/100 along with the KAT100 loads grand into the wire.  I work many, many stations on 160 meters.  The K2 is very HOT on 160.  The Inverted-L could be a long-wire too...just a hunk of wire 130 feet long or so fed against a counterpoise or a good ground.  IT does not have to be in a straight line either.  The KAT100 at the QRP version of the tuner is an LC Network which will load just about anything...even your rain guttlers (not plastic ones though).  Any antenna you get on 160 (except for the big ones) will have limited bandwidth, but that is OK.  Use the tuner.  It won't be ideal, but heck, ham radio is full of trade-offs.
 
If you can't get the 130 feet out in the yard, you might try to add a lump inductance at the end of the wire with about 10 feet after the inductor.  The inductor could be say 2 feet long made out of 2" PVC pipe with #12 wire wrapped around out...the taped.  It is not an exact science but it works.  With the inductor, the bandwidth gets real slim.  
 
I've been on 160 by feeding the coax shield on my 80 meter dipole...using the feedline shield as a radiator and one leg of the 80 meter dipole.
 
If you have a tower with a beam on it....use a gamma match wire connected to the top of the tower on a 3 foot arm...and a small variable capacitor at the bottom.  I've ran 100 watts using this configuration and the capacitor was a ganged 365 pf BC capacitor.  You just have to tune the capacitor for the part of the band you want to work.
 
These are just a few ways I've gotten on 160 meters.  As far as the K2 is concerned, fantasstic on 160,  The KAT100 tuner or the QRP tuner is also fantastic on the band too.  I've used the 130 foot Inverted-L (long wire) on 80, 40 and 30 meters too with great success with the KAT 100.
 
Have fun...and get on Top Band.  It is pretty poor conditions in the summer, but you will be surprised in the fall and winter what you can do with simple antennas on 160 meters.  Plan now.  I always work on the 160 meter antenna when it is very cold outside.  Try not to do that.

  I wonder why 160m is an option on the K2 other
than the fact that it won't fit on the main PCB.
To me, an HF transceiver doesn't deserve the name
if it doesn't have "Top Band".
  I finished my K2 just a couple of days ago and
have not been on 160m, except into the dummy load
for aligning. I didn't buy the 160m option just to
'complete' the K2 - I intend to use it.

1 - 160m isn't HF, it's MF.

2 - You don't call the K1 or KX1 HF rigs? How about a homebrew mononband
QRP rig? If a radio meets the design goals, and those goals didn't
include covering every single band, I don't think that makes it
undeserving.

3 - Don't take this email too seriously - it's not intended to be!

The K2 is a fantastic QRP radio for 160m.
I have one of the few 160m QRP WAS certificates issued by ARRL.
And that's doing it from the left coast :-)
Go for it and enjoy.
Good luck and 73
