How to build a simple AM transmitter.

Take a old radio apart. In my case a portable GE Am/FM type that also runs off 4 "C batteries. Attach output of CD player or SPKR out to Tuner C1 connection on Old Am. Hook other side to Ground or Metal IF canisters. Attach a small 3 foot wire to C2 side of Tuner. Mine does better in the upper band on 1650 Khz. Tune your Am transmitter to match another radio say around 1650KHZ. The Receiver will be at 1650 the Transmitter may be slighly less on the dial at say 1300-1400KHZ. Just because of the IF harmonic is 455KHZ. It my go into 1/2 harmonic or so. It will sound your audio "LOUD" into transmitter 10-30 feet away. Turn down CD player volume until it is clear(not distorted). Its very sensitive in the section of INPUT it doesn't take much to drive the Transmitter. Keep experimenting until these connections are perfected. Once you get it to work, solder it in place. Play all your favorite songs right on your AM receiver. I get an easy 100 feet range with 3 foot Antenna.Have fun. Also On C1 short it across to that screw on C1 side To AM coil wire with the audio wire SPKR out. It seems to be clear,loud and steady. Drive a ground Rod into earth 6 feet attach to metal IF canisters(Grounding) If you get it to work---put it inside a square box and drill holes and add Volume knobs for audio and Gain knobs. Build a RF pass filter at Antenna to better signal by shunting antenna to ground with a coil(40 turns) 100pf capacitor plus a 1k resistor in series with capacitor,where you attach Antenna Screw and Ground screw in back of your box. Antenna can be mounted outside on a 10 foot pole with 75 ohm coax feeding to transmitter. Build your antenna with 8ft. aluminium pole(tape it off with black tape). It should get decent gain.

Intermittent LOUD shorting sound

I would prefer to hear it to be sure which one it is, but the four biggest causes of noise in a wireless system are: 1) Something hitting the mic (check to make sure the mic is free of clothing, other people, faces, etc.) 2) If the mic is a lavalier or in some way has a cable that plugs into the transmitter, something pulling on it could create a loud noise. Check to make sure it's in snug. 3) RF Interference with another mic or some other interference source. Try changing the frequency. 4) Something blocking the signal between the transmitter antenna and the receiver antenna. This is most likely to happen with a lavalier in someone's pocket or under clothing, and/or if the transmitter is far away from the receiver. The SLX series is okay for what it is, but part of why it's on the cheaper side is because of its limited distance. Unfortunately the only ways to alleviate this are to a) Reduce the distance, b) get a stronger wireless system, c) move the transmitter somewhere that the antenna is free, and d) invest in True Diversity antennae for the receiver.

It looks like you have a real scientific project. It sounds fascinating and it seems to go well beyond the mere enjoyment of a simple Short Wave Radio. My suggestion: Put your hypotheses/questions to the test and you will form an informed opinion.

yes, there are two fuses on the main wiring harnesses for the remote start brain. also try reprogramming the transmitters:
1. Turn key to ignition position (ON) 2. press and release programming button (you will need to locate this in your vehicle, ask your installer where this was placed; it can normally be found under the driver's side of the under-dash) 3. press and hold programming button 4. while holding programming button, press lock on each transmitter one at a time. 5. Turn key off and remove, test transmitters.

1. Turn the Ignition 'switch ‘OFF/ON’ 3 TIMES and stay in
ON position. Within 15 seconds.
2. Push the Valet switch 2 times and hold in on the 2nd
push, when a long chirp is heard then release the valet
switch. You are now in the Transmitter programming mode.
1. Press the Lock button on transmitter 1 until the siren

transmitter is now programmed to Car.
Exit: Turn Ignition to 'OFF' position, or leave it for 15
seconds. 3 long chirps will confirm exit.
Note: If more than 4 transmitters programmed, the system
will only keep the last four.
