Jake,
In my many years of portable operations, I found that to make reliable
communications, you only need about 20w on CW and 50w on SSB. It is a lot
better than 5w QRP (night and day difference), and not much worse than the full
100w.
You can even try it for about $300. Look for an old Argosy. I prefer the
(analog) Argosy-I instead of the -II, because the -II has a digital display and
more battery drain. As I recall, the battery drain of the Argosy-I was only
about 300mA on RX. It had 30m, but no 17 or 12m, so that is really its only
drawback. I'm sure you will be pleased with what you can work with 50w.

Hey Bob,
Glad you enjoyed the story. The antenna was Todd's, so I can't tell you exactly
what it was. But it was a 20/40 m wire, with an extendable pole to
33 ft, and it worked fb on both bands.
He has his own website. Go to qrz and type in N4LA, then from there you can
click to his website for more info. When you get to his website, disregard his
version of that day, (all lies), but somewhere there you'll find info on the
antennas used. If not, just send him an e-mail.
By the way, this past Saturday, the xyl and I found a trail leading straight up
to the top of Mt Rogers, the highest mtn in VA. When it warms up some more,
both she and I are going to hike to the top. Then later this summer, I plan to
go back with ham equipment and activate that peak. And there are lots of peaks
in my area that have never been activated for SOTA, so it's going to be an
interesting summer.
I still haven't decided on what radio to buy for this SOTA activity. The only
drawback against the Eagle is the cost. $2k for a radio to hike up and down mtn
tops is too much money to spend. At the same time, I'm not into qrp, as I have
found that most of the time, it's not the qrp operator doing the work, but the
stn on the other end with superior antennas to cpy the little gun. So still
searching for a 100 w rig that is affordable for mtn top work.

Jack:
Great story!
The radio of choice for portable operation seems to be the Yaesu FT-817.
It runs 2.5W on internal battery and 5 W on external power People seem to
really like them, though I hear that the receiver overloads in the presence of
very strong signals, and some folks do not like the menu
structure. I've never tried one myself. Most of the other amateur
radios advertised as "portable" draw 1 to 1.5 amps on receive, not too good for
a battery power budget. At the other end of the spectrum are the military
packsets, like the AN/PRC-104. They are cool, rugged, and expensive, even on
the surplus market. Good for spot frequency use, but tuning the band won't be
that much fun using the frequency selection switches. Again, I've never tried
one. In the middle is Ten Tec. While they don't seem to be marketing the
Argonaut VI as a portable rig, Ten Tec has made efforts to keep the receive
current drain down and 10 W is a more practical level that 2.5 or 5 W,
especially for working SSB. A lower cost alternative, if you can find one would
be the T-T Scout or Argosy. I have successfully used my Scout portable on
several occasions. I crank the power back to 25-30 W and it will run fine on CW
on a 7 Ah battery for at least a couple of hours. A bigger battery, like those
automotive jump starting packs, will give you longer run time.
Running the Scout at lower power will also make it run cooler, which helps
prevent VFO drift. The receive current drain for the Scout is 600 mA. I think
that the Argo VI would be better, especially if one can buy or fabricate a pack
or handles for it.
What do you use for antennas? My portable preference is simple dipoles instead
of the short, loaded dipoles and verticals. I made a reel-out dipole from
surplus AN/CRT-3 antenna reels and a smaller version using plastic "campers
clothesline" reels. Here are some antenna ideas from

73, and let's hear more stories!
