Hello,
Have been doing a little experimenting lately, and thought I'd post some findings.
Would be most appreciative for any thoughts on, or comments.
Do a lot of listening to an airport control tower on 118.5 AM, about 10 miles from house.
On my Uniden BCD 996 scanner, using a Scantenna in the attic, it comes in crystal clear.
It also comes in crystal clear using a disconne in my attic feeding a JRC NRD 545 shortwave set.
On my new GRE 500, it always comes in with loads of static.
This is so with the rubber duckie, or connected to the same Scantenna as the BCD 996.
Have tried it with the ATT on, but as a subjective guess, the S/N is pretty much the same.
So, what's happening, possibly ?
I read about an inter-mod problem with these GRE scanners, but really don't understand
inter-mod theory, or how it manifests itself in the 500.
What is inter-mod interference; what causes it, e does it show up, how does it manifest itself, etc. ?
Any way to minimize ?
Could this be the reason why ?
Would, or should it, be effected by having the ATT on or off ?
All in all, I'm pretty happy with the 500.
Haven't really done a side by side comparison on other frequencies, but most seem to be clear.
It's this one, unfortunately, that seems to have all the static, and of course, it's one of my favorites.
Thoughts ?
Thanks,
Bob
