Any luck with checking antenna connections? I have a service manual if you need it. Tuner section in this old girl predates the LM7001. Uses ha1137-38 chips, bit more complex to repair.

Even with just a short wire, this model should be receiving a number of stations. Is there an IC inside marked LA7001 or something similar? If so, it is probably defective. This is a common failure. I'll look up your specific model later to confirm.

I have a old pioneer stereo double cassette deck reciever model # RX-Z15, i dont understand the bal/unbal fm antenna hook ups cant get reception , need to know where to hook up the antenna or what kin


Buy a 300ohm FM Y antenna wire screw the spade ends into the balance hookup and fasten the Y section on your wall, "higher the better" this will improve reception. The antenna can be purchased at Radio Shack or Tv repair shop.

How do i hook up an antenna to the pioneer sx-950


There are two antenna sources on the Pioneer SX-950.

Both of these outputs are located on the rear panel of the receiver. The AM is a permanent mount. The FM is standard RF/Coax which will run to your antenna.

Antenna Inputs: FM 75 ohm, FM 300 ohm
Am Ferrite Bar Antenna

Hope this helps,

Improve reception


HI there,

Well Yes you can improve the reception, please follow the below steps -

Improve FM Radio Reception -
 
1. If you don't have an antenna connected to your FM receiver, purchase a simple dipole antenna--a simple T-shape flexible wire-- and connect it to the FM antenna inputs on the receiver. Because FM signals are directional, you'll want to experiment with the positioning of the wire to find the best reception of the station you're trying to receive.
 
2. If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.
 
3. If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.
 
4. If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.
 
5. Temporarily switch to monaural mode to improve a weak signal on an FM receiver.


Improve AM Reception -
 
1. Gradually rotate the radio 360 degrees. Leave it in the position where it sounds best.
 
2. Reverse the AC plug if it isn't polarized. (If you can flip the plug over, then it's non-polarized.)
 
3. Plug the radio into a different AC outlet.
 
4. Move the radio closer to a window.
 
5. Experiment to learn if appliances and powered products in your home are causing interference: computer monitor, television, electric blanket, light dimmer, fluorescent light, hair dryer, air conditioner, smoke detector. If possible, turn off the offending item. Otherwise, move the radio to another room.
 
6. Upgrade to an external antenna if your receiver, tuner or radio has a place to connect one.
 
7. Buy a passive AM antenna that doesn't need to be connected to a radio or receiver.

Good Luck!!

Thanks

I have a 'vintage' (70's) Pioneer sx 535. What is the simplest way to hook up an FM antenna?


Depends on the connection on the back. Most older receivers used unbalanced 300ohm connections. In short, any speaker wire will do. Newer models used a "F" type connection (Coax end) which you can still cheat and get a 75 to 300 adapter at radio shack or any other local electronics store. Hope this helps.

No FM reception on CMT-ED1 Sony shelf system


There is hardly ever an internal FM antenna -- only AM. You'll need at least one of those twin-ax dipole antennas (there's one with every receiver bought).

You can test the concept just by putting a single piece of wire on each antenna terminal -- when you do this reception should improve immediately, but will not be as good as with the dipole antenna.

My turntable works on old reciever and not new one


A traditional turntable only works on Phono (which contains special preamplification and equalization circuitry designed to raise the the level and flatten out the response of a phono cartridge).

After you do that, iIf you're not having hum problems I wouldn't worry about the ground. Or try it again on the FM Ground.

Connecting Pioneer SX-737 Receiver to computer problems


I've been recording LPs for over a year now.

I've got the turntable outputs plugged into the phono inputs on the receiver amp.

I'm taking the Y cord (pair of RCA connectors at one end, mini plug at other) from the Tape Record (these are what you'd use to send a signal to the tape deck for recording) on the amp to the "line in" on the sound card. You may want to look up the specs on your sound card to make certain that you've got the plug in the correct socket. There may be a "line in" and a "microphone" socket. Use the "line in"

What recording software are you using? Audacity is free and is ok. I'm using Goldwave (costs ~$50) and highly recommend it. MUCH better than any other package I've tried. Just google "goldwave" to find it.

The recording software should have an option for selecting / specifying a source. If you have "microphone" selected and the y cord going into the "line in" socket, yoiu won't get anything.
