[JRC] Emergency Power

Fabio,
The generator is not a bad way to go. If it works for
your situation. If you prefer batteries because of noise,
fumes, gas storage etc. you might want to consider
Concorde AGM batteries (Absorbed Glass Mat). They can be
charged just like a lead acid but there are no dangerous
gases that have to be vented. These are used in aircraft,
boats or anywhere people and batteries are contained together.
They are sealed but not a gel type battery.

I'm not affiliated with Concorde I just know they make a good
product.
Good Luck,
Regards,
Jeff, N0OST

Hi all,
    I am planning to add emergency power to my ham station. That is a
long-term project, so I have no hurry.
I was thinking about some batteries (maybe lead-acid ones) and a homebuilt
battery charger to keep them charged.
I live in a city and power outage is not usual, so I just need emergency
power for some hours, just in case something serious happens.
My VHF works on 12 V so I think I won't have big problems here.
Now, the problem: the only rig I have for HF is JST-245, which of course
runs off 220 volts AC, so I think I need a rather big (and expensive?)
inverter.
At full power (TX) the '245 is rated at 900 VA if I remember correctly, but
if I use it at about 100W output I think a 600/700 VA inverter will be
enough.
Will I need a pure sine inverter or can I live with a cheaper one?
Thanks for any suggestion and comments,
73
Fabio IZ4AFW
