There are many new 22 channel FRS/GMRS radios being sold now. The biggest selling point is the increased range the higher power GMRS frequencies give the user. Although FCC rules require you to have a GMRS licence to use the GMRS requencies and increased power levels (the unlicensed FRS radios are limited to 1/2 watt) few people are bothering with a getting one.
Since we have used FRS frequencies to help the public in the past I thought I would find out what the additional GMRS frequencies and channel numbering of the new radios. Keep in mind that the CTCSS tones used by different manufacturers are numbered differently. So channel 2 code 26 may be different from one radio to another. A tone of “0” is no tone decode on most of these radios. Also Motorola is marketing radios that use DCS (digital coded squelch) which is also different. Learn how to use the tone squelch search feature of your radio, if you have it…..
It took a while to find this but here it is:
