Now go and check your range. Use your car and your odometer to check the range. Do the

final tune on “TUNE” (Check to be sure the meter voltage is still peaked). Adjust “AUDIO

LEVEL” control for best sound on your radio.

Keeping the antenna as vertical as possible will help your range. It is also critical to keep the

antenna away from metal. Don’t for example, mount the antenna so it runs up against, or

parallel to a metal drain pipe.

Before you leave make sure that the customer knows that if they have any trouble with the

transmitter to simply unplug the wall transformer or power supply. Because of the high RF

voltage generated the unit can induce a signal into phone lines, stereos, and other

equipment.

If you find that you are not getting good range check the transmitter ground system, if you

notice that when tuning the unit that instead of a sharp peak in the voltage the voltage

barely moves while you are tuning you probably have a bad ground. Electrical grounds

will not always be acceptable, you may need to run a separate ground or find another

ground. You could use a water pipe that is going to ground for example. Also if you are

getting poor range make sure you have set the power properly. If you are having troubles

recheck all wiring and connections. If you have carrier but no audio be sure the audio pot is

turned up. Be sure the power is connected to the power terminals and not the sync terminals.

Be sure the crystal is in and seated (unless you have the freq module). See the trouble page.

Section 15.219 Operation in the band 510 - 1705 kHz.

(a) The total input power to the final radio frequency stage (exclusive of filament or heater

power) shall not exceed 100 milliwatts.

(b) The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3

meters.

level of the unmodulated carrier. Determination of compliance with the 20 dB attenuation specification

may be based on measurements at the intentional radiator's antenna output terminal unless the intentional

radiator uses a permanently attached antenna, in which case compliance shall be demonstrated by

measuring the radiated emissions.
