In reply to MM0FMF:
As Helen tends to use the 817 more than I do these days I will say…‘We’ leave the Internal battery in the rig. This is because on one occasion the SLAB had not been charged as much as we thought (someone turned off the power when we went to bed) and on another we had a problem getting the cigar socket connector to make a consistent connection when it was a bit damp due to heavy mist (it just kept sliding out).
I think I tend to be a belt and braces man. I always carry at least one hand portable as well as a main rig and I like to cover all bands. That way if it is a nice day I can take my time and work every band I can or if conditions are rubbish I can scrape a few contacts somewhere.
Having Helen with a second station means I am a belt, braces and a spare pair of trousers man. Helen and Caroline both have their own dual band hand portables in case we get separated, but they are also useful as back-ups or in the worst case we could take turns to leave the activation zone and work each other.
Not sure what Barry’s problem is with the 817 on FM. I am fairly sure I have had over an hour out of the Internal battery on FM from a summit, which I would guess is about half what you get on SSB. Did six hours once in which I flattened the 817, the 3Ah Slab and two Kenwood PB39 high capacity batteries for the TH-G71E. I still had two PB38 batteries for the Kenwood and the 23cms Icom IC-12E with two batteries but I ran out of time and had to go and pick up the kids from school.
These days I have the 857 and two 7AH slabs which is usually enough. If I ever get around to going down the LiPO route I may have to get a small tent because I am likely to not come down until my batteries are flat or I get my 100th contact whichever comes first.
PS Could do with an 817 power cord so I can fit Anderson Power Poles but it must be an angled plug like to original. Any ideas where I can get them cheap?
