Re: VHF MSR 2000

There are actually at least three vhf ranges in the MSR family. 

Depending on the specific model and duty cycle you'd need to 
check the numbers against the book chart.  

The receiver is the first thing to check... there are high range 
versions that don't come down into the ham bands without serious 
(pain in the @$$) mods.  Most of the transmitters will do the 
entire range without mods... just the proper alignment. 

The PA should first be checked by the book/manual for the 
band range and by asking various people (with serious msr 
experience) for their thoughts. Almost every MSR VHF PA will 
work down into the ham band turned down.  Some models and 
versions adjusted down a lot (75%) ... some at nominal 
values. 

There are so many different models of the PA it's probably 
easier to get the actual model number and also write down the 
receiver model and check them with the book AND an "msr 
person". 
 
Most flying blind msr people convert the commerical units 
down to the ham bands only to trash the power amplifier by 
running it well above the de-rated out-of-band range values
(power level). 

Smart to see you asking the questions first...
