In reply to G1ZJQ:
The 125 watts is ERP, i.e. 25 watts out to the 5 element which has 7dB gain (x5). Now I do have real power to my elbow. I used my big linear to qualify SE-005 and SE-007. That was 150 watts out to the 5 element = 750 watts ERP… and the antenna positioned at just 3 metres on that occasion - I did crouch down!
My usual power source is a 3.3AH sealed lead acid battery which weighs 1.3kg. I have 4 of them and they cost me £8 apiece. I can get 1 hour of SSB operation running 25 watts output with a further 30 minutes on FM out of one battery. I had to resort to a handie to complete my run on FM on Cyrn Y Brain when I stayed for 2 hours. Usually capacity is not a problem. For the 150 watt linear I use a 12AH sealed lead acid battery which weighs 4.2kg and I definitely know when I have this and the linear in the backpack!
I feel that a decent antenna is more critical than the power, especially when you are up one end of the country. It applies equally as much down south as up in the SB’s. 2.5 watts to a simple antenna should get the summits in the middle of the country qualified and I have done this on occasion. However, I still think that it is worth taking a decent beam as it helps the more distant chasers to copy you. I’ll certainly be taking 25 watts and the 5 element up Sighty. The beam dismantles by the way and is strapped to the mast for carrying.
As far as points are concerned, you can only claim them once in a year, but I’m fairly certain the system does award the bonus points if a second activation is undertaken in the winter period, though quite why you’d want to do the Cheviot twice in a year… to view the boggy ground and the mists? It was 10 metres visibility when I was up there last!
