Poor reception
I am getting poor fm/am reception in my 1997 F-350. its not the radio cause I installed a different radio when I got the truck and it was the same. Is there any way to test the antenna cable and antenna? Is there a resistance spec to them or any thing? Any thoughts would be great.

I just bought the truck in december. it had an older pioneer cd/am/fm in it when I bought it. then I put a Sony MP3/AM/FM in it. both radio's had the same reception. my 95 f-250 and my 99 superduty plow truck both had great reception in this area. but this truck will get the stations but not at the range as the others and not clear at all. not like static but jsut poor sound quality when it should be near crystal clear at just a few miles form the radio tower.

I think I might just do that. I will probably just un screw the antenna and remove the base to see what is there. I am pretty sure there have been front end body work done to this truck so we'll see maybe its as simple as bad connection.
any way to use a multimeter to test the cable while I have it apart?

Once you remove the antenna stub, you can ohm out the antenna cable. Unplug it from the radio and test between the shell and the tip. Should read an 'open'. Connect the stub and it should now read 'short'. What you'll prob. find is a short with antenna stub removed. Most likely a shorted cable somewhere. Prob easier to go to junkyard and get another antenna WITH the cable out of a junker. Prob $.50

Its probably a poor chasis ground at the antenna base. Clean it up and it should be fine. Keep in ming that NO aftermarket radio will have BETTER reception than a factory unit (unless you have a Rockford Fosgate Declo made unit)
And WTF is 'ohm out'?

Well none of my trucks have factory radios other than the 99 and they all have better reception than this one does so I will check what you guys have talked about.
Ohming out is the process of taking my ohm meter and testing for resistance and/or continuity of the antenna cable. ie checking for open or short in the cable.

Hunyda (the car company) does. Their 2001 and older headunits were made by Denon and they kicked ***. But the newer ones dont hold the same quality level.
Rockford decks were originally made by Delco - not Denon. Back then they were the only thing I would sell a customer that listened to AM because their tuner was basically a delco OEM unit. And yes they did switch to Hyundai in 02 - I know because I took part in a focus group at Rockford for their re-design. Denon did make 3 models for them for the Euro/Asian markets - basically re-badged hi-end Denon units that were a total flop when they offered them here in the states.
You can have 1 or the other when it comes to AM/FM reception - good reception OR good sound quality. Its a compromise between frequency response (SQ) or reception - if you increase the freq response you trade reception and vise versa. Ever notice you can hold a station longer if you put the tuner in 'mono'?
