[TenTec] A Fun Day with Ham Radio, and a Question about Portable Operating

Mon Apr 15 21:43:55 EDT 2013

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!
