The difference between the FT817 and the ND are staggering (not).
The ND gives you a 1300ma pack instead of 1000ma as well as 3 colours for
the display instead of two. I heard a rumour that the PA stage is different
and the radio will cover as standard the Alaskan 5Mhz channel without
doing a full broadband mod.
Have you noticed that on 2m the SWR indicator appears to be a bit gay,
showing 2 or 3 bars even with a reasonable match ? This was also
mentioned on the www.ka7oei.com website, which is mainly original MK1
notes, but I have noticed it on my ND too, it says 4 bars on a dummy load ;-)

Not very ecofriendly. Let's just hope Mr Brown doesn't start taxing us
for it (personal carbon emmisions quota).

I have here 2600ma cells, so that would be two rounds of 10hrs.

Uncle Joe Stalin said that too.

What worries me is can the charger circuitry provide enough initial current
for the larger cells without some on board regulator getting a permanent
headache.

I can certainly conferm that the colder it gets, the less current available.
Same with normal car battery.

I seem to recall that Lithium Ion where mentioned on the Southgate ARC
website recently. You may have to search it's recent news archives but it was
only fairly recently I saw.
