Set the repeater type to Generic and enter your receive frequency and PL. You will now be back at the CHANGE/VIEW menu, in Repeater Mode. Keep pressing F2 until you reach the GET/SAVE menu. Connect the programming cable to the receive radio and press F2 to read it. Press F10 again to skip the transmit radio. Press F2 (Read Repeater), and then press F10 for a Generic Repeater. Do you see an option of F6 (Change to Repeater Mode)? If so, try the following steps: From the Main Menu, select F3 (GET/SAVE). On some radios, even though the accessory connector is not fully programmable, Pin 8 can be made to provide an active-low COS output, by programming the radio in Repeater Mode (see step 4).Ĥ. I've measured the voltage on Pin 8 as described in steps 2 and 3, but I am not seeing an active-low transition when the radio unsquelches.
(16-pin radios): With the radio upside down and the accessory jack facing you, Pin 8 is on the bottom row, 4th pin from the right. Where do I find Pin 8 on the accessory connector? Does this drop to less than 0.1 volts when receiving a signal with the correct PL? If yes, this radio can be used with the RA-2. You should now see +12 volts on Pin 8 with the receiver squelched.
Reconnect the positive voltmeter probe to Pin 8. Repeat the measurement from step 2, but this time, use a pull-up resistor to +12v (wrap one end of a 10k resistor around the positive voltmeter probe and connect the other end of the resistor to +12v). Do you see approximately +5 volts on Pin 8 with the receiver squelched, and less than 0.1 volts when receiving a signal with the correct PL? If yes, this radio can be used with the RA-2. Check Pin 8 with a dc voltmeter (positive probe to Pin 8, negative probe to ground). On some 16-pin models, Pin 8 provides an active-low COS output, even though the accessory connector is not fully programmable. I have read my radio with RSS, but I do not see any option for changing the accessory connector (F9 does not appear on the Radio Wide Configuration screen). If no, change Pin 8 to these parameters and write the change back to the radio. If yes, this radio can be used with the RA-2. Check to see if Pin 8 is already set as: (Description = PL/DPL & CSQ Detect Data Direction = Output Debounce = No Active Level = Low). This takes you to the Accessory Connector Configuration screen, where the definitions of pins 4,6,8,9,12 & 14 can be viewed or changed. Here, (if the radio has an expanded logic board), you will find a choice of F9. Go to the Radio Wide Configuration screen (F2).
#COS MOTOROLA GM300 FULL#
We have one for my work and they are turned down to 15W and then bumped up to a full 30W with the antenna to avoid burning out the finals in the rigs.ġ. I dont recommend running the GM300 full out on TX either as they are not designed to be a full duty repeater.
