Kenwood TS-711 (2m) and TS-811 (70cm). They has PC control possibility
Also TM-255 and TM-455 are good for basestation use, without external

That's very interesting curve. Guessing for most home users its more
cost effective to purchase more cells for increased power than paying
more for higher efficiency.
I really don't recall what I paid for remote radio site solar power
about 15 years ago. I believe they were 30 to 50w panels and cost
about $400. Our first panels were made by Arco and Solar Electric
(something) made the last ones we installed.
This was commercial mountain-top comm sites only reachable by
helicopter about one month/year due to weather. Our largest site was
shared with State of Alaska who maintained a mw link from Kenai
Peninsula to Kodiak Island (about 70 mi over water). We had five
radios, most of which were 5w but two had 30w amps (all
FM). Originally we used a battery bank rated at 10,800 AH at 13.2v
(were air cells) which had to be replaced every three years. But we
installed a two panel solar charged system using two 100 AH
deep-cycle batteries to supplement the fixed battery bank during
roughly 6-months of high sunlight in the arctic summer.
We thought that would extend the main battery bank life to four years
but it did not quite do it. Energy use analysis was complicated by
multiple users so our guess fell short.
Helicopter cost each year for one trip to the mountain ran $5,000 for
40min flight one-way and standby time on the mountain while we worked
(usually four hours). After being stuck on the mountain for seven
days in 40F-40mph winds in rain we decided to keep the helo on the
mountain so we could get off quickly in event of bad wx which could
develop in 15-min socking in the mountain top for long
duration. Winter had the shelter covered over under 15-20 foot of
snow with winds upward of 200 mph. Top of the mountain had
year-round snow cover.
Nice to be retired <smile>
