SOTA.
To my mind one needs TWO SOTA radios. One 5W-2-W, 40-6, up to 6lb or so,for
the easy, < 6 mile RT day hike with a YL carrying the lunch and water and
me carrying 20lb of radio, battery, and antenna stuff. Then there is
another radio, 2-3 band, maybe 3lb max for radio, battery, antenna, the
whole station, for the > 6mile RT hike, sans YL sherpa, so packing own
lunch and water. I've done both hikes, the YL is only good for 7 miles :-),
a number of times, but have yet to bring a radio along. The PFR-3B looks
like the best bet for the later. Esp considering it has a built in tuner.
The Argonaut 509 is good for former. Alas, I sold mine to help pay for a
Drake R7. I got a lot of use out of the R7 but now it just sits.
