Description

The HR70 is a digital display analog FM transmitter. Apply a signal to the XLR or RCA inputs of the HR70. Select what frequency you would like to broadcast those signals on (88 to 108 MHz) and you are now sending signals via FM radio, assuming the antenna is connected properly. The HR70 also has a talk over circuit built in.

The H70 is especially ideal for situations where you can address a group of people in their cars for "parking lot gatherings" such as worship services, educational seminars, drive-in movies, etc.

Even though the HR70 is a micropower RF transmitter and requires no FCC licence, for it to function properly, good RF practices still apply. The wire antenna provided is set up for the middle of the band or about 92MHz. For any transmitter to operate at its best, it must be earth grounded. You can think if it as "pushing" the signal against the earth. Range can vary widely, depending on grounding, antenna placement, obstructing building/walls, etc.. We have had people report ranges up to 150 feet. Some experimenting may be required at your venue to find the optimum installation for your situation. Antenna included.

  • Simple way to broadcast signals over FM
