One of your base station transmitters is disabled and the belt pack receiver is looking for a signal. Also, your belt pack receiver or base transmitter may be mistuned.

Check the base transmitter “separate” and “combine” switch to ensure that the two transmitters are feeding the ports that you intend to use. If you are going into a TX-8 combiner, then you must place the switch in “separate” and connect both transmitter antennas. If you are using one transmitter antenna, then you must place the switch in “combine”.

Make sure that all base stations are in “Master” mode and make all settings. Connect the cable and cycle power on the base stations. If using one to five “slave” base stations, make all setting in the “Master” Mode then change to “Slave”. Again, cycle power on all base stations with the link/sync cables connected.

You may be getting AM radiating RF on your wired comm through poorly shielded chassis or cable. Keep all systems powered up and disable the base transmitters. Get some distance between the base transmitter antenna and the wired comm cables and chassis. Also, use only the amount of RF power out of the base as is required for the task at hand. You rarely need to use 250 milliWatts.

The headset cable is the counterpoise for the VHF transmitter antenna. It must be connected for proper transmission from the belt pack

The belt pack locks to Channel 1 to ensure a closed loop system. Channel 1 must be turned on in the belt pack receiver. If you do not want to hear it, turn the volume control down.

Short answer:

  1. Check for proper placement of RX antenna in comparison to TX antenna.
  2. Check your operating frequencies.
  3. Check your RF 50ohm Low Loss cables.

Long Answer:   There are three things you need to check.

  1.  Check your placement of your base station RX antenna and make sure it is not in front of a TX antenna or pointed directly and positioned too close to a video wall or another piece of equipment that puts out high RF noise.  RX antennas should be placed high, behind and to the side of a TX antenna and away from items such as Power Distribution, lighting dimmers and video walls.  TX antennas should be placed high as well.
  2. Check your TX and RX frequencies of your base station to make sure they are not being stepped on by other frequencies or tuned in a high noise floor environment.  If the frequency is clean, but there is a higher than normal noise floor, you can attenuate the RX sensitivity at the base station to help lower the noise floor.  The pack will TX out more effectively to the base station.   You can do this individually or globally.
  3. Check your 50ohm Low Loss RF cables for a short in the connector (shield touching the core) or possibly a broken pin in the connector.  Cables get damaged if not taken care of.

Short answer:   It is not recommended unless you power up in TX Off mode.

Long Answer:   It is not a good idea to power up the base station without antennas connected because the TX amplifier is looking for a load when it is powered up.  An amplifier with no load will cause strain on the amp and shorten it’s life or cause it to fail.

An alternative is to power up the Base Station in TX off mode.  Hold the TALK button on the right while turning on the Base Station.  Let go of the TALK button until you see ”TX OFF”  in the LCD screen.  Another benefit of doing this is that your base station won’t interfere with any other frequencies at your location if your base station is not already programmed.   You can turn the TX in the base station back on manually or by using the software to program it.

No, your batteries will not drain if left in a unpowered battery charger.  Always top off a battery before an event if left unused in or out of the battery charger for longer than a day.

Make sure all of your base station RX inputs are connected to an antenna via a VF-8 or DB-VIC RX multi-coupler.

RAD recommends the user to wear a two-way radio on the OPPOSITE side of the RAD pack to avoid interference between each other. The 2-way Radio transmission can potentially damage the receiver board in the RAD pack if it is a few inches in proximity.
