Both of these generators are individually controllable as to frequency and level. The frequency is adjustable from 250 Hz to 3000 Hz in 1 Hz steps. You can then use the output of these generators to send Morse code or various beeps, including dial tones and busy tones. You can connect up to eight RI-300 series controllers together to create links or remotes. This buss is full cross-point compatible and fully programmable.
Controllers can even pass commands to each other.
On the expansion buss, a controller can operate as a repeater, link or remote base. This auxiliary buss architecture of independent controllers for each radio ensures maximum flexibility and reliable operation of your system. The RI-300 includes digital potentiometers that can be remotely controlled. With this feature, you will no longer have to made a trip to the repeater site to adjust the audio or squelch controls. The RI-310 squelch circuit is directly controlled and monitored by the microprocessor.
