FM35 SETUP:
It’s time to set up and test your FM35, then get on the air. You’ll need an an-
tenna and a line level audio source such as a CD player or computer sound
card. Here we go!
FM35 operation is about as simple as it gets. The [SETUP] button cycles
through the various screens, and the [UP]/[DOWN] button adjusts the value on
the particular screen.
First of all, adjust the contrast pot, R1, if needed, by turning the orange top to
the right (clockwise as you’re looking at it) until it’s about halfway to its stop-
ping point.
Connect the included power supply. Also connect your antenna. You shouldn’t
operate the FM35 without some kind of antenna; a transmitter should always
transmit into a load of some kind and not into an open, especially with a 1 watt
RF power output.
Turn the transmitter on. You should hear a beep and see “FM-35, Rev 1.7” on
the display, then in a few seconds the screen will change to a default display.
The default display shows the current set power, frequency, clipping detector
status, and the VCO voltage while still attempting to lock. Readjust your con-
trast now if you need to.
Pressing the [SETUP] button once brings us to the frequency display. Here,
using the UP/DOWN buttons, we can select our frequency of operation. Note
the voltage display which indicates the current VCO voltage. This helps us
diagnose any problems if something goes wrong. If the voltage stays low
(<0.5V) or high (>9.9V) no matter what frequency we choose, then the FM35
may not be locked.
Set your desired test frequency now. You should choose an open or “dead”
spot on the FM dial as a starting point if you’re not yet sure what frequency
you can transmit on without interfering with anyone. Check the FCC informa-
tion section of this manual for more details on legal part 15 broadcasting. Use
the UP/DOWN buttons to select your frequency.
Pressing the SETUP again gets us to the mode display. Here you can toggle
Stereo and Mono modes.
Another press of the SETUP button brings us to the volume display. Connect
your line level source to the FM35. Your source can be a CD player line out, a
computer sound card line output, or any other audio source you desire as long
as it is line level. Anything other than line level audio will sound distorted and
cost you time troubleshooting a non-existent problem. NEVER connect the
