For de-soldering I use a de-solder iron with a squeeze bulb on it from
Radio Shack, works great.

A recent thread discussed a problem disassembling a MSR2000 continuous duty PA.
That triggers this query: Does anyone know if Motorola used a higher
temperature solder on the MSR2000 units?
My reason for asking is that this past weekend I had a hard time removing three
leaky electrolytic capaci
Larry,
Are you looking for a 4, 8 or 12 channel radio?
Do you need a set of accessories also? Standard or Systems 90?
I will do some looking if you would like. I may know where there is a decent
radio.
Maybe we could do some trading.

Maybe a little Black Powder might be needed?

Yep, not enough heat available from most solder suckers, irons
and guns.

I do not know about Nextel, but, the US DTV signal fits into a 6 MHz bandwidth.
We use a mask filter to ensure that the bandwidth is no more than 6 MHz.
500 kHz from band edge <= -47 dB
6 MHz from band edge <= -110 dB

The Free Motorola Micor VHF/UHF Mobiles & GE Low Band Mobiles are all gone.
FWIW it would probably be made to workat a price, but for ordinary
consumer type Amateur Radios, not really.
We have been "conditioned" to the sub $400 price range radios that do
everything, go everywhere and have less than ordinary receivers in them. :-)

I was wondering about that myself.
A couple of comments on the other aspects:
1. I see this as falling flat on its face. May as well mandate D-STAR.
2. How are the commercial people fitting SNFM in 7.5 kHz channels as
they have been doing on VHF?

I am using an ASTRON 70 amp ( un-metered ) supply in my rack. It has a fan
on it that I have NEVER seen come on. Is there an internal adjustment of
some nature based on the ambient temperature that can be maneuvered to make
this fan more 'useful? Thanks.. - Mike

Well put, Jeff. IMO

Apparently Carson's Rule works different in Florida than it does everywhere
else.
