TEMPORARY REMOTE RECEIVERS
When participating in an event where communications are essential it nice to be able to use them. If your main communications is via a repeater, it would be great if you can get into it. If you are on the fringe area of the repeater, you may still be able to hear the repeater, but can you get into it?
Most repeaters use power that may be 10 to 20 times higher than the radio getting into it. You may be able to hear the repeater, but you may not get into it, or you may be noisy. If you are using a 5 Watt Hand Held radio, the repeater may be as high as 50 or 100 Watts, you can hear it, but it can't hear you.
To help get into the repeater a Temporary Remote Receiver near your event activity would help a lot. Not all repeaters have the ability to use remote receivers, so you have to know which ones do, or have the repeater set up with an auxiliary link receiver for Temporary Remote Receivers.
Another way to get the coverage you need is to use a cross band repeater set up in a mobile on a hilltop near your event. The cross band repeater will receive and transmit on one band toward the repeater, and receiver and transmit on another band toward the hand held radios.
These are just a couple ways to provide the communications that may be needed during an event.
