Thanks for the responses - I always like to learn about the point of view that others have.
Yep, the Uniden definitely can't compare to a Furuno. I really love the Furuno, and that is what I use on HF most of the time. It does have IF level DSP processing, and will knock out just about any type of interference. However, it doesn't sound nearly as good in the AM receive department as a CB due to the narrow AM filter. However, SSB sounds EXCELLENT when using the 6 Kc filter.
Boy, some of the guys really love you when you transmit with that filter on SSB...
My radio is a PC 78XL, though. It does have a dual conversion receiver. However, I could buy about 130 PC 78XLs for what that Furuno cost the Navy. I just enjoy seeing how well I can get an inexpensive CB to perform. I've had really good luck with my experiments so far.
Bushwhacker, I'm gonna have to build one of those relay-type NB testers. It probably is better than a hair dryer. I get a charge out of watching my wife shake her head when I'm using the hair dryer that way, though!
I run a Heil audio-level DSP along with my Furuno's IF level DSP, and it does a really great job on most bands. However 160 meters is a special case, and requires the underground receive loop. The loop is 5 feet underground (to the top), and sits in the middle of a concrete "box." I use a sump pump with automatic water sensor to get rid of any water that might seep into it. With the loop, my noise level is about S2 on 160M most of the time. I have a rotator on it, and can null out even more static that way. This makes for really nice listening.
Switchkit, I really like AM, too. It definitely sounds nice! I've had a couple of Cobra 25, and they always do an excellent job at noise reduction. I might trade this PC 78XL for one of them if I get tired of fooling with it.
I really enjoy tinkering with CBs, but it's no big deal to me if this one doesn't meet my expectations. I heard good things about the unit, and just wanted to try it. I listen with a Uniden Grant LT 99 percent of the time, anyway, and it is as close to perfect as I think I'll ever get in a CB radio - especially after adding the 2SC2999 in the front end, and schottky diodes in the NB and AM detector.
Thanks again for the comments; y'all have a great week!
