The Radio Programmer Is for so Much More than Just Memory Management. |

Save your file as you work. This is a computer, after all, and you would hate to lose your work should the system fail. Actually, create and save as many files as you want or need. You could have one file for home, a different one for the vacation house, another for the trip to your son’s house, another for the yearly 3K run and picnic where you help direct traffic and want the radio to be programmed with only the frequencies for that event. Remember, radio programming is an overwrite process. Everything in the radio is replaced by everything in the file. |

Limit Memories Limit Memories are used by the radio for Program Scan. Program the same details for Limit Memories as for regular memory channels. Many of the Limit Memories are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank. |

DR Memories The DR Channels are special memories of the radio used for quick manual D-Star setup from the radio’s face. D-Star channels do not have to be programmed here before being saved to memory. |

Call Channels Home/Call channels are special memories accessed through one button recall on the radio. These channels are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank. |

VFO The program makes available the same VFO’s as in the radio (usually one per band). Remember these are not real memory channels since the details are lost as soon as you tune the radio manually. There is no one button recall for these. You do not need to program into VFO before programming details into a memory channel. These channels are preprogrammed in the radio and while the frequency can be changed to another within the band, they cannot be left blank. |
