Help & Advice

i assume you are looking  for a cheap and simple HF rig, 

have a look at QCX from QRP-Labs.com if you are going to be using morse, can be kit (which technically currently M7's are not allowed to use) but can be bought pre-built (but Hans and his little elves building them have a little backlog)

if you are looking for something more multimode (voice, data, CW) have a look at xiegu X6100 (5w on internal battery, 10w on 12v) , has built in ATU, battery and is HF+6m (about £600) i have one for mobile / POTA use

there are a couple of other Xiegu radios (G90, 20w, ATU, HF only would need ext battery)

depending on terrain you can throw a long wire over a tree, or take one of the fibreglass poles (see sota beam) or moonrakeronline.com for wire antennas etc for HF

if you are going to be hiking up several summits have a look at https://www.sota.org.uk for a little bit of a challenge
