In the sprit of the only stupid question is the one that goes un-
asked.
Here goes:
I have a Micor UHF repeater mounted in a 46" x 19" cabinet.
It is now a ham band repeater that I have added a new NHRC-5
controller and IRLP interface. The modules are mounted as follows:
Top: Custom built 12V PA c
My only input is that heat rises, and the heat of the PS will rise and keep the
duplexer warm. I would be concerned that the heating of the duplexer (and
likely cooling at off-peak times or climate change) would cause the metallic
parts in the duplexer to expand and contract possibly throwing i
Just remember heat rises so the hottest items usually go high in the stack ,
assuming you have a top mounted fan.

Hi Barry,
My 2 cents! A 100 watt Micor lofts along regardless of temp. If you can
stand it, so can a Micor. Not all of us have 72 degree air conditioned, clean
rooms! If your PA has the BIG heatsink, its continuous duty, the mobile
heatsink need some cooling because they are only rated

I put a VHF repeater together this summer in a
Stromberg Carlson cabinet that the phone company
retired and had to install a fan in the top of the
cabinet to get the heat removed. The cabinet was
insulated with one inch foam on top, bottom, sides and
doors. It was a side-by-side rack cabnet with
Very familiar with these , wonderfully well made and will outlast all of us
although in my part of the world they have fans Std .

I agree. This rack had the mounting for the fans, but
they had been stripped out by the time it made it to
us. The hard part was figuring out just what
dimension fan would fit -
