Im getting my shack started and need some input on a good sturdy mobile
for
2 meter. Ive looked at several alinco ones and like what I see. Also what
does everyone think of the icom v82 ht? Also is a 7 amp power supply
enough
to run a mobile?


I concur with the other's recommendation.

I use a Yaesu FT8800 and like the dual band (simultaneous reception and
linking) capabilities.
I could use a 440 low power ht to key the mobile and transmit at higher
power on 2 meters.

Because FM requires continuous power, I recommend that you have a power
supply capable of 15 amperes ICS if you plan to use it in your shack. If
you want to use it to power a 100 watt transceiver as well plus some
additional accessories, get a 50 amp supply, but in either
case, be certain to evaluate how much rf interference a switching supply
puts out.

50 amps is not necessary for a 100w transceiver. (Was that a typo, Ed?) I
think the most I've so far ever seen recommended by a radio manufacturer for
100w is 22 amps. For example, my Astron 20A (20 amp - duh) supply powers my
IC-735 just fine. I understand what you mean, though, about 2m being
continuous, as opposed to CW and SSB being intermittent on transmit.

A 20 amp supply would be what I'd recommend for the 2m 50w radio in the
shack.

As for power supplies, you should consider a 12-volt Absorbent Glass Mat
(AGM) battery with a maintenance charger (the kind that shuts itself off
when the battery is fully charged). That will give you pretty much
whatever surge current you need, and if your power fails your station
stays up.

AGM batteries are sealed, can be used indoors, and can be mounted in any
position (e.g. on their sides or even upside down, so they claim). They
are readily available (I get mine from Batteries Plus). I have a
105-amp-hour AGM battery for my motorhome, and a 33-amp-hour AGM battery
for my ARES "go kit".

I'm told that the so-called "gel cell" batteries are actually AGM
batteries.

I strongly agree. These are a great back-up for power failures or for
field operations. I work the OKC Marathon every year, running my Yaesu
FT-857D and FT-897D from Power Battery Company 91-Ampere-Hour AGM
batteries given me when we got rid of our Muckin' Huge UPS at work.
When they're not in use, I keep them charged, so that I can run the
station during our all-too-frequent power outages. One of them will run
a Yaesu FT-*97D for about 8 hours, I've found, in my typical usage
pattern, which is listen-mostly.

Warning: these are HEAVY! Sulfuric acid and lead both are very dense.

The 91AH batteries weigh about 77 pounds each; you want them rigged
with some sort of carrying harness if you have to move them, or use
a dolly of some sort. If you're putting them on a table, shelf, or
other support, it needs to be strong enough, and if they're going in a
vehicle or trailer, they need to be secured so that side loads don't
cause them to fall.

position (e.g. on their sides or even upside down, so they claim). They
are readily available (I get mine from Batteries Plus). I have a
105-amp-hour AGM battery for my motorhome, and a 33-amp-hour AGM battery

There are lots of sources. Your Yellow Pages will be a great help here.

batteries.

Seems to be the case.

hi

also check you local hamfests, many SLA batteries from
computer data center ups systems recent pulls.
Most of the time they are in service 3 years and then
pulled and replaced with new. these are under constant float
charge and can provide several years of service life for
ham radio use.

I'd agree with that. I have a thing here called a "Wizard Power Cube"
which I bought at a rally some years ago. It contains a 20AH dryfit
lead-acid sealed battery, a maintenance charger and also an input for a
solar panel so you can use it when out portable on a contest for example,
using the solar panel to get some charge into the battery. I don't recall
the make, but I think the guy selling them made them himself.
