QRP has it’s challenges, i’d love to go and try qrp when i would go hiking outdoors, thinking of setting up the 706mk2G for that, would only stick to 20m band coz most likely the hiking would be done daytime, if there would be camping and staying out, then i will include a 40m antenna. thingking of going solar like you

but bring a small lead battery for backup. its almost autumn here and would like to take advantage of the weather before winter comes.
btw, how does the R-72 performs, i’m thinking of getting the R-70, there are some cheap R-70s i see in Ebay.
1-3db loss is not that bad, will definitely think about that setup.
also, i want to ask, if ever i go to the Philippines and want to go on air. What do i need to have to go on air? Can i use my call sign here (i’m at ITU region 2) in the Philippines (which is under ITU region 3) or would i be needing some sort of permit, or take the NTC exam to have a separate Philippine Call sign to use while on air in the Philippines?
