[R-390] Re: R390 cooling fan

[Dan Arney]

The shields all were standard silver and not black and they  operated 
for years just fine and the biggest percentage of them still do not have 
black shields. My guess some nit picking eenggiinnneeriinng smart ass 
hole decided after 40 or so years that the Gov. should spend unknown 
amount of taxpayers money to cool it down maybe 10 or so degrees.

IIRC Nolan said in his 5 year test it made no difference.

Where is the actual proof of the fans or black shields making the 
receivers any more reliable.

Proof I mean Gov./Collins printed hard copy dated and with the 
appropriate numbers as a field Mod or SB. That would make TURDS a lot 
easier to see.
