Here are a couple of tricks I have used successfully over
the years for both fixed station and portable operation.
My favorite paddle for backpacking is the very light weight and durable
BullDog Paddle.
The problem of "What-in-the-heck-do-I-stick-it-to" was solved
by mounting a small compact make-up mirror from the XYL's empty collection
to the heaviest thing we carry in the pack the small gel-cell battery.
Super glue holds it to a flat side and some small rubber feet on the bottom
of the battery keep it firmly in place.

It can also serve as a signaling mirror if you are lost or injured on
the trail. These mirrors can be round or oval shaped and are easily removed
from their plastic holders. This set-up is very comfortable and feels
just like home when a small table or park bench is available.
My other must have is a very simple RF output indicator for
the little 2-3 watt rigs most of us use. A No. 47 bulb soldered across
a BNC connector makes an excellent dummy load and is a good
match for 50 ohms. An SWR check shows a 1:1 SWR at these power levels.
It is very reassuring to be able to check your transmitter's output on
the trail or in the shack. Don't hit this with a full 5 watts or the bulb
will be destroyed. From 1 to 3 or 3.5 watts are best and still give an
indication with 500 Mw or less.
This size pilot lamp still exhibits a steady 50-ohm load at
these power levels. I have tried many other bulbs and the # 47 is the
only one found to exhibit a good 50 ohm load. They are available at Radio
Shack if you cannot find one in the junk-box. It is certainly a tiny and
lightweight reassuring accessory to have along on the trail or around
the shack.
I love simple homebrew stuff for operating and camping.
