It seems like it would be cheaper and easier to do away with the solar
panels and charger. Use the money to buy a few more batteries. Charge
them before FD and you're good to go.
Think about this. It may even rain on FD! The solar panels would only
be good as an ad hoc umbrella or tent

This is exactly what we do at Field Day every year. We search and
pounce, so our transmit duty cycle is relatively low, but after
operating all afternoon, the 7 Ahr battery used with the QRP K2 is
almost fully charged (assuming sunny weather, of course). We use two 5
Watt solar
Brian:
We have plenty of gel cells for Field Day, and, as you noted, don't
really need to use the solar panels at all. However, we get 100 bonus
points when we make QSOs using a battery charged via solar energy. You
can't forget bonus points!

I got into some wrong notes this morning. 600 MA is the amount adding
the KPA-100 adds to the K3 during key down or transmit conditions. My
earlier measurements were the right ones. I have the larger solar
controller from Don Brown KD5NDB and it works well with an AC power
supply I use to
I'm very interested in hearing responses to solar setups for use with
the K2 and would appreciate seeing replies shared on the list, if it's
not considered too off-topic.
Thanks,

Ken, I show a 33 watt solar charger in Northern Tools
that is $299.99 and 38X11-3/4x1 and 13 lbs. Doable
in a car, but a bit big for back packing. Also
pricey. It does not include a controller at that
price.

Andrew,
When reading the other posts and seeing those large Solar Panel
wattages, I think they are using a K2 but with the 100W option. I
can't imagine needing a 33W solar panel to power the base K2 model.
On a nice day, I guessing you could hook up a 7 Ahr gel cell and have
it charged with a
