[VHFcontesting] 902.01???

[dfmich at comcast.net]

Gentlemen:
I have been putting a BPF in front of my DEM xvtr to make the band usable in 
en71, Ft Wayne IN. I have it arranged that it can be inserted or not using a 
transfer switch. I leave it out unless the S meter on my IF rig shows an 
upscale reading which often reaches S5 or more. It clears right up with the 
filter inserted. I use the 3-pole filter that shows up in the literature 
using UT-141 for resonators slightly modified for ease of tuning.

Prior to setting this up the band was oftern unusable. I put a spectrum 
analyzer on my antenna and found a very strong signal about 10 Mhz below 903 
and then a whole gob of "stuff" a little lower where I expected to see the 
cell phone signals. Given the signal 10 MHz below 903 I would not like to go 
down to 902 as it would make the filter job that much more difficult.
