F.01U.362.808
A – This could indicate a variety of influencing factors. The first thing to check is if your system is,
or is not, sharing a frequency with another signal at the receiver. While observing the receiver’s RF
meter, turn off the transmitter. If the RF meter continues to show signal after the transmitter is off,
your transmitter is competing with another signal at the receiver. To solve, perform the scan
process, tune the receiver to a new clear frequency, then turn on and sync the transmitter to the
new receiver data. The second thing to check is receiver antenna placement and cables. Ensure
that your antennas are out in the open in the shared space of the transmitter (meaning not behind
walls or in another room), away from reflective or grounding surfaces, and connected to the
receiver with appropriately-rated 50Ω BNC-terminated coax cable. The third thing to check is the
receiver squelch. Many times, having the squelch set too high will greatly reduce system range.
Try lowering the squelch (number value) to increase system range. The fourth thing to check is
transmitter output power. If a compromised range is accompanied with low RF signal on the
receiver’s RF meter, set the transmitter output power to high, then look for improved range.
Q – Why is it hard to find an open frequency in my location?
A – RE3 shares the UHF radio spectrum primarily with UHF television broadcasters.
Geographically, some broadcast areas are more densely packed with television broadcast signals
than others. A full system scan looks through the entire tuning bandwidth of the receiver and will
locate frequencies which are not affected by UHF television or other RF signals. Knowing your
local RF environment is important. Those local television stations which broadcast their strong and
wide signals into the air are regulated by the government, and consulting government databases
will help identify the frequency areas occupied by local broadcasters. RE3 tuning bandwidths are
relatively wide, allowing generous tuning options, however if the airwaves aligning with your
particular RE3 tuning bandwidth are filled up with UHF television, finding open frequencies will be
difficult. Selecting the best band for your area is important. Something to consider is if you are
using your RE3 set in the USA or Canada, the 6M band will have no competing UHF television
signals because 653-663MHz is designated for wireless microphones only as a result of the
reallocation of 600MHz initiatives.
Q – I manually created frequencies for my multi-channel system. Why am I getting
interference between the channels?
A – Manually creating custom tuning schemes without the assistance of frequency coordination
software may contribute to the problem described. RE3 frequency groups are strategically created
to be intermodulation free using advanced frequency coordination software. It’s likely that your
self-made grouping has created destructive intermodulation artifacts which would be avoided by
staying with our factory groups. Use RE3 factory groupings. They work well.
Q – Why doesn’t the extra RE3 transmitter I bought online work with my RE3 set?
A – The set you originally purchased was pre-configured with a matching transmitter and receiver,
which both operate in the same frequency band (5L, 5H, 6M, etc.). If you add another transmitter,
it has to be of the same frequency band to work. As this particular question is about additional
transmitters, it should be pointed out that adding a second transmitter to an existing set with plans
to use both transmitters at the same time with the one existing receiver will not work. At any given
time, one of the two transmitters tuned to the receiver’s frequency must be off. If they are both on
and the same time, substantial interference will occur.
Q – Will the lavalier microphone I have with my older RE-2 system work with RE3?
