Jim can you give me more details, like what model # to look for. The 
only time it will be portable will be 2 times a year, for 2 one day 
events where no one repeater will get into. But setting it up on this 
one site covers the entire we need communications. Then it goes 
back to it normal site. This is a small Motorola GR 300 repeater 
mounted in a 42" tall GE cabinet. This unit puts out 15 watts - not 
high power.

Hi Jim, 
I really don't want to argue with you, but it can 
be done and I've done it numerous times. It all 
comes down to a number game (the specs) and a 
reasonable approach.  

I've used surplus Decibel mobile duplexer's in 
narrow split operation for years. If properly set 
up and secured, they should not detune. 

Portable two meter repeaters can work pretty well, if 
you approach the project with reasonable expectations. 

Many/most of the common "flat-pack" VHF duplexers are 
designed for wide splits.  Some combinations of the 
small & mid size Harris, Decibel, Sinclair and 
Phelps-Dodge packages can be set up or modified to 
operate narrow splits. The preformance will not be 
spectacular, but the repeater will work ok. 

cheers,
