Your New (Used) GMRS Radio

Following are the directions that are packaged with each GMRS radio:

This radio was purchased used. It was refurbished by an unpaid volunteer in the local neighborhood. The radio is sold to you at cost. There is no financial profit. It is impractical to offer any guarantees on these radios other than to say that they have been tested and performed to specifications when they were sold to you.

You must obtain an FCC license ($70, soon to be changed to $35) to obtain a call sign. You must use your call sign when using this radio. The license and call sign are good for 10 years for everyone in your family. There is no test for the license.

You need to practice using the radio on the local Neighborhood Radio Watch channel usually once a week in the evenings. During these practice sessions you will test the Paging alert channel and practice using correct procedure with the Net Controller and many of your neighbors.  Following is a description of what the buttons on your radio do:

Charging the Battery

May contain: wristwatch and digital watch
Charger and Cradle

Your TK-380 radio comes with a new power supply and charging cradle — they are shown in the photo on the right. You can leave the radio in the charging cradle while you are monitoring one of the channels at the same time.

The new chargers we have begun supplying with radios this year have automatic functions and will slow down the charging rate when the battery is nearly charged, stop charging when the battery is fully charged. It is possible to overcharge your battery if you lift the radio off the charger and put it back on the charger when it is already fully charged. It is best to take the radio off the charger about once per week and leave it on for 24 hours, then replace it in the charging cradle.  That prevents the battery from developing a "chemical memory" that can shorten its life.

 

Selecting Channels

Your radio can be programmed for many channels.  When you receive it, it will be programmed for about 18 channels. Some of these channels have special uses.

The Repeater Channel.  This channel is first in the list of channels and has the spelled out name of your community. This channel connects you with everyone in your radio net (and a little beyond).  Each community radio net has its own name, such as Oak Hill, Cosumnes R, Coloma/L, Pollock P,  

When you use your neighborhood's repeater channel, your transmission is received by a much more powerful radio (a repeater station) on the highest ridge in your area. From there, it is rebroadcast so that you can reach everyone with a radio tuned to that channel and within range of the repeater station. That makes your mobile GMRS radio into a much more powerful radio. Usually, you will be leaving your radio on and tuned to your repeater station channel.

You should only use your repeater station for serious events, radio checking and for practice once a week at the direction of the Net Director. You should not use it for informal conversations with your neighbors, unless those conversations have to do with safety issues of general interest to the community, such as power cut-offs, loss of telephone reception, information about a wild fire, etc.

Your repeater channel 1 is usually monitored by a “Net Controller.” When interacting on this channel, you should follow the direction of the Net Controller.  He or she will receive and direct all traffic.

The Alert Channel. At night, you may wish to tune your radio to the “Alert” channel and turn up the volume. You cannot talk on the Alert channel, only receive paging alerts (loud beeping),  If the pager is triggered by the Net Controller you will be awakened by very loud beeps that indicate that the Net Controller has an important message. The beeping won’t stop until you get up and turn the radio to your local repeater channel to hear the message.

Some people prefer not to use the "Pager" channel but instead leave the radio tuned to the local repeater channel during the night. You will gradually learn the correct volume setting that will wake you when you hear the tones that are broadcast to turn on the pager alert. When you hear the alert you will not have to change channels to hear the following message since you will already be on the repeater channel.

The Other Repeater Channels. Down the list of channels are all or most of the other repeater channels. Each has its name spelled out. Follow the same radio etiquette when using these repeater channels as you follow when using your local repeater channel.

The Talk-Around Channels (T/A).  Each repeater channel is followed by a Talk-Around (T/A) channel. This channel allows you to talk on the same frequency as the repeater channel but without going through the repeater -- so your transmission will not be broadcast widely across the entire neighborhood. Use the T/A channels following each repeater channel to communicate with neighbors while keeping the repeater station clear of unnecessary traffic and available for emergencies.

Extra Informal Channels. Following the list of repeater and t/a channels are one or more extra channels that are compatable with the more-common, inexpensive radios that are popular for home use. You can use those channels for home things, such as, when one of you is checking the circuit panel outside and the other is inside to see which lights go on and off. These channels can be used for informal talk. In general, it is best to use thesae informal channels when talking casually with family and friends.

 

What If My Hand-Held Can't Reach the Repeater?  The range of hand-held radios is limited. Almost always, their 4 watts of power will provide plenty of range to reach the repeater. But if you live on property that is blocked from the repeater, you may need a more powerful radio.  The EDCARC can provide
