[time-nuts] Austron 1210D Manual Update

[Had]

No problem John,

I've only had this 1210D since yesterday and have found that 
everything works except for the batteries of course. I have not had 
any time to do any real work with it. I have been watching it on and 
off this afternoon running into a SR620 with a external Cb standard 
and the 5MHz looks to be pretty solid.

I have two 1210D-1's due to arrive mid next week. I know one of them 
needs work, so we shall see. I'd really like to have a self contained 
10MHz transfer standard w/battery.

I'm looking at a less expensive alternative to the high dollar "F" 
cell battery back. Two Canon camcorder batteries in series will give 
you 14.4V at 7000mAh. I think they will fit in the tray with room 
left over. BUT, they are LiON and I'll have to rework the charging 
circuit. Two eBay batteries cost about $28.00. Only an idea at this time.
