    This worked perfectly right out of the package. I am not a radio pro but was able to get it set up and radios programmed properly on my own. Morse code ID works just as stated. My repeater is almost finished...Thank You!

    ID-O-MATIC 4 repeater controller for Motorola gm repeaters

    As a EC for our county ARES team and trustee for four repeaters I have used four different brands & models of repeater controllers on Motorola radios. The ID-O-Matic is a top pick for use in Amateur radio or commercial use at bargain price. Easy to program, versatile, small in size and the reliability factor is outstanding. The rebroadcast audio is as good or better than controllers costing 5 times as much! Sine wave foot print is near perfect on cw id. I am currently using three units in our county & will install two more in the next 2 months to replace ageing units. The unit preforms perfectly in all environments. We have never had a lockup in two yrs of heavy use. Two systems are linked via VoIP and delay is adjustable down to minimum hang time for seamless operation. The only addition ...

    I asked for the unit to be programmed with the repeater call sign n9fjs. I hear no CW. out of the unit.

    I have tried to reach Dan to find out why I have no CW. ID. Its been a week and no response from anyone. I need to find out why it is not IDing in cw. I will send it back for reprogramming if necessary. The program Putty will not load up on my computer. I like the product it self , but with out the program being right it cannot be installed the way it is. The voice ID is unreliable. audio cuts out halfway throught the message. I can be reached at home 847-587-7067. I hope to be able to get this resolved so I can give this a good grade.

    Big power in a little box

    The ID-O-Matic 4 Repeater Controller is a great value; small size, low price, large capability. This unit allows you to connect two ham radios back-to-back creating a standalone VHF/UHF repeater. It can also be used on HF as a foxhunt controller, a beacon, or an ID timer. This controller is universal to almost all radios. It is not designed for any particular model radio. The digital inputs and outputs can be programmed for active high or active low levels. Three pots easily control various audio levels. Unless you are very new to amateur radio the programming options are straight forward and easily understood. The GUI is DOS based and some experience with that operating system will help understand the flow of the programming. It programs fine with Windows XP and Win 7. This ...

    Plug and play!

    This IDer/Controller is just the thing for setting up your GMRS repeater using the Motorola GM300/ Maxtrac radios. It is a high quality circuit board that is well laid out, adjustments for CW ID deviation when it triggers during a voice transmission, can be timed to ID at what ever interval you need. I highly recommend this product to anyone setting up a GMRS repeater or someone who wants to have their ID/ callsign transmitted at regular intervals automatically. Customer service is top notch with RadioDan.
