Purchased an IR repeater from Radio Shack but the transmitter does not seem to be working (no LED at all). Receiver alone works when remote is activated at closer distances (LED flashes) Both receiver and transmitter are plugged in using supplied 120v adapters. Should there be an LED present in the transmitter?

GP300 radios will operate either radio-to-radio or in conjunction with a repeater. If your radio no longer works through a repeater, you might check to see if it will work in talk-around mode (radio-to-radio). Check with your repeater service provider to see if the repeater is in working order. One other item which might occur with a repeater would be if your radio is no longer recognized by serial number by the repeater. This is also something the service provider could help you with.
I have read some very bad reviews about that product, you may be better off returning it to the store and asking for a replacement, and maybe you could ask the guys at the store if you set it up correctly first.
There may be issues with the unit or the source of the signal. The scanner may have lost its sensitivity. There are a lot of articles on the unit about programming etc. The problem is that it takes special equipment to test the front end of the receiver. The company the made the scanner for Radio Shack was GRE in Japan. They moved to China and then closed, they have reopened and are now owned by Whistler.

Yes, if you mean XM reception. Your microwave oven is actually a radio transmitter near the Satellite Radio frequencies and when you use your microwave, it WILL wipe-out XM radios. Even my neighbor can do it to mine! Check it out - boil some water and watch your signal fade in and out! You're going to want to move the radio, or use a 'repeater' for it, or use the playback of prerecorded.
the ir feed receiver amplifier has failed a common sony fault on older units a fix is about $100.00 or use a repeater ir blaster from circuit city for $40 and try that you can return if no success the repeater eye covers the receivers originaland pumps up the out put into the unit
You begin by setting up your existing (((XM)))
antenna the one that came in your home kit (not included in repeater package) in a location that gets good
reception of the (((XM))) signal. This may be outside, or on a south facing
window sill. This antenna gets plugged into the rear of the Delphi (((XM)))
Radio Signal Repeater Transmitter. A power jack is right next to the
antenna connection, and should be plugged in and to the wall with the
included power supply. There is also a "PWR OUT" selector switch on the
rear of the unit which allows you to control the strength of the signal
transmitted from the unit.
Once the power and antenna are attached, both
blue indicator lights will light up on the face of the unit. The blue antenna indicator will light up only to signify that
the antenna is attached correctly. It does not let you know whether
your antenna is in a location receiving a good (((XM))) signal or not. You
will have to look at the signal strength indicator on your (((XM))) radio receiver do
determine best location for the (((XM))) antenna.
Once you have this setup, place the Repeater
Antenna close to your existing (((XM))) Radio and plug it into your antenna
jack on the (((XM))) radio cradle. This connector is identical to your
(((XM))) Home Antenna provided with all Boom boxes and (((XM))) home receivers and
kits so compatibility is guaranteed. The Repeater Receiver Antenna does
not require any separate power connections.

Possibly your new equipment doesn't use IR (infared) as the media for the remote. I have used the pyramid and different versions of it for DirecTV/Dish and most everything else for years with no major problems. occasionally a unit will fail, but that happens. If the red light blinks on the "transmitter" (no antenna) it should indicate that it is receiving IR from the remote. The "receiver" (antenna) has to be oriented correctly in front of the unit to be controlled. I put the receiver no closer than 5' to the unit. The signal coming out is a cone shape and it's easier to aim the further away you are. As a test, you could try using the remote to control a stereo or something else, even a fan. If the remote has a led or a dark red plastic cap on the front end, it should be an IR unit.
An infared detector is just a transistor that is covered with clear plastic. matching the spec on it though is hit or miss. first be sure it is not the ir trasmitter, take it to radio shack and see if their infared re-transmitter broadcaster sees it . or aim at a digital camera or hold near a radio though that only hears the digital part. radio shack has some iR transistors in stock usually . basically you can just plug one in and it may work but you may have to know how to bias (balance ) the transistor to work correctly. there are many places to scrounge a ir receiver transistor old tvs , learning remotes, laptops , printers , you can inject the output signal of the remote into the ir circuit to see if it is working but you need to add a resistor and drop the voltage a bit. hope that helps some.
The Kenwood VR-510 does indeed respond to IR remotes. I now use a Logitech Harmony H659 which is IR only.
Your issue is a problem with the VR-510, actualy the whole series had a problem with cold solder joints on an assembly behind the front panel. Fix that and fix the problem. It frustrated me for 5 yrs.
Go here for the fix:
This site has the fix well documented: http://resnet.uoregon.edu/~gurney_j/kenwoodrepair/.
All is working great now!
