Purchased a used Sony STR-AV770. Only for AM/FM radio listening and for to use with a Sony 5 disk CD changer.
CD connection works and sounds great!
When I try to tune in AM or FM stations the volume. I am having a very difficult time pulling in stations. So, first any suggestions on an good antenna to use for AM & FM stations.
My second issue is that I get a 'pulse' type feed back through the system in the tuner mode. Not with the CD player. But when I am on a frequency that is not receiving anything the read out is flat and then every 5-10 seconds a pulse of noise comes through and shows up on the monitor of the receiver, any suggestions would be great!

I just had this happen the other day. It completely jammed up. I ended up having to remove the radio and disassemble the upper changer section to get the disks out. The problem with mine was that one of the disk trays broke and jammed the mechanism. I ended up gutting the changer and and reassembling the radio and installing it in the car to use the AM/FM function. I'm currently in the search for a new radio to swipe the CD changer off of since even radios that you do not have the security code for will work as the coding is in the radio section and not the CD changer. The changer attaches to the top of the radio with 2 T8 and 4 T10 screws and connects with a ribbon cable between the two modules. You'll see the ribbon cable when the top CD changer mechanism. Be careful removing CDs this way as if the player's rotating assembly is not retracted, it is very easy to scratch the disk. Unfortunately I lost a Velvet Revolver disk this way. Good luck! If you are on one of the the big boards I go by TR GTO on both if you need to contact me and I'll walk you through it.
I'm assuming your using a RF unit (radio frequency). Whether this unit inserts in the antennea line or is simply broadcasting an FM signal via it's own antennea, it is still transmitting a low power FM signal. The idea here is to find an unused FM channel in your area, set your radio to that channel and program the Sony RF unit to use that channel. The signal the Sony RF unit is transmitting is low power due to FCC regulations and to minimize the possible interference you could cause to someone else's FM listening.
You are likely using an FM channel that is being overpowered by a real FM radio station. This is usually solveable if you only travel in your town by picking an empty FM channel. If you travel alot, the channel in your town that is empty may not be the case when you travel 50 miles away. That's just part of the problem inherent when using radio frequencies to get your music into your radio. You have to be willing to deal with it.
As far as passing vehicles, I'm going to assume that the vehicles that are interfering with your radio are doing the same thing you are doing, they are using FM radio frequencies to pump music into their radios and they are using an FM frequency close to or the same as the one you are using. Since having an unused channel on the FM band is pretty rare these days, if there is one, you can bet everyone is trying to use it for their own purposes since it is "quiet", until you come around!
You can use any CD changer that has an FM modulater. You would listen to it by tuning in to a station on your tuner.
The sales person at any place that sells car stereos would be able to show you the right type of changer.
If your radio has a cd changer controller built into it, you need to check with the dealership to find out what the OEM changer would be. But a FM modulator will work with any car stereo.
Kenwood, Pioneer, JVC, Clarion, Alpine all sell FM modulator CD changers. I would not personally buy any of the cheaper no name brands. The money you save on the cost is not worth the difference in quality. Panasonic is a very good brand for car stereos but not home stereos, but I don't know if they make CD changers. if they do, that would be a good brand.
then what is your problem? tuning proibem? well i guess based on my experianced poineer car stereo were not repairable unless theres an available parts... the problem is might be in the IC tuner.... you need to contact for an service technician to repair in this kind of matter...gud luck!
