I am using a Larsen tri-band 140/440/800 antenna mounted on the trunk lid connected to a Uniden BCD996T.

And then about 10 inches away on the trunk lip, I have a Diamond NR72BNMO dual-band antenna which is connected to an Icom V8000 that I use for APRS. Only when I am in an area that doesn't have very good APRS coverage, I run the Icom at 75 watts. The rest of the time I run it at its "low-mid" power setting, whatever that might be, I'm not sure of the wattage. The TinyTrak is set to beacon every 3 minutes.

I previously had a BCT15 as a scanner, but suddenly it wasn't getting very good reception. My installer got it and tested it compared to the BCD996T and found there was certainly something wrong with the BCT15. I put the BCD996T in the car and then sent the BCT15 to Uniden for repair. I checked the status of the repair and they are just now starting to look at it and it should be shipped back out in a little over a week.

Now, my BCD996T is having a similar prblem. It is having reception troubles. I cannot receive any VHF/UHF, although 800MHz reception isn't suffering as much -- I still get some signals but not as much as I should -- but I still can't receive anything on 140 or 440.

I am pretty sure it's not the antenna, because it worked when I swapped scanners.

My question is this: if I let the APRS radio transmit at 75 watts at about 10 inches away from the scanner antenna, could the RF from the APRS radio go through the scanner antenna and into the scanner and cause some damage?
