1st August 2015
Used my Yaesu FT-7900 dual band mobile radio, which hasn't been getting a lot of use recently as I've moved my stuff to a different room but don't have the VHF/UHF coax going there yet.
The 7900 works well for portable operation, even on an 11.1v battery pack it still does full power in the low and mid settings (between 11 and 15 volts there is no significant change on a power meter, turning the voltage up and down from a variable PSU). Not tested the output power on High, but a 4Ah pack wouldn't last very long with 50 watts. If I got really desparate for QSOs from somewhere I think I could still manage a few minutes with >30 watts though.
From the track below the summit I picked up 2 WiFi access points on my phone:
Crake Valley Holiday Park (nearly 3km away)
The Caravan Club Wireless - both on 2.4GHz
