I recently picked up a Uniden PRO538W from Fry's for about $50 bucks or so and wanted see if anyone else was having the same results with their setup.
My SWR readings are the following
I mounted the unit below the steering wheel, above my left knee on the drop-down panel.
Ran the power directly to the battery, and grounded the CB to the metal supports near the fuse box area.
An 18 ft cable runs down, along the door floor sills, under the rear seats, out and wraps around the rear door (didn't drill or funnel through the rear wiper rubber seal yet) to the mount on the rear tire carrier.
Using a cheap 4' non adjustable fiberglass ground antenna from Fry's and initially had readings over 2 closer to 3, for the lower channels until I purchased a antenna spring which brought it down to its current swr levels.
I thought I needed to increase the length, so I purchased a 64" steel whip from Radio Shack and then tested...
All SWR readings were 3+? Was it because it was metallic instead of fiberglass, in combination with being longer?
Also if all readings were 3+, doesn't that indicate a ground fault? Weird because nothing changed besides the antenna and
all grounding should have been the same?
Did the whip antenna change the ground plane and reflect back much more power?
Not sure, so I changed it back to the 4' fiberglass with the spring.
Should I keep the setup as it is now???... Or... get a 5' fiberglass and see if I can get the SWR's lower?
Also, I installed a PA speaker, which emits a loud static noise when the gain is turned up. Is the gain and squelch supposed to be turned all the way down??? When I turn the gain and squelch all the way down, there is no more static... However the sound volume when speaking is not loud at all. When it emits static, it's as loud as an icecream truck on a hot sunny day. But when I depress the microphone and test, the audio emitted is only about 10% as loud as the static????
Sorry for al the babble, but I figured more information the better....
Thanks in advance, and appreciate any help anyone can provide.
