Uniden HR2510, HR2600, President, Ranger Amplifier keying relay buffer interface

Description: This unique product will finally allow your Uniden HR2510, President Lincoln or other* radio to key an external RF Power Amplifier! As you know, there are no external contacts for keying an amplifier on many radios, so we developed this very sensitive circuit that will take the switched voltage found inside your radio and provide a relay output closure to key an external power amplifier with relay keying contacts when you key your microphone. NOTE: YOU must locate and solder or otherwise connect the included cable to the correct place to pick up the voltage on transmit that will activate the RBI-1HS. We also include an RCA-RCA cable to go to most amplifier T/R keying circuits. On OUR test HR2510 radio, the correct wire is shown in the pictures. Pictures are of HR2510 YOU MUST check YOUR radio connection point has <1 VDC on RX and >3 VDC on TX. On my test HR2510 radio the point we selected (ORANGE wire as shown) has 0 vdc on RX and about 5 VDC on TX. I do NOT know if all Uniden radios look the same, YOU must use your voltmeter to be certain the point you select has near 0 vdc on receive and above 3 vdc on transmit. I do not know for sure if the HR2600 has the exact same connection point as the HR2510 BEFORE you buy for ANY radio, check with your voltmeter to see if you can locate the correct connection point. Picture 1 shows unit Pictures 2,3,4 show connection point to orange wire Picture 5 show unkeyed voltage at that point, 0 VDC Picture 6 shows keyed voltage at that point, 4.95 VDC Picture 7 shows the tiny amount of current drawn to key our interface from that connection point (white face meter) This listing is for our Radiodan RBI-1HS relay buffer interface and the proper cables to connect to your Uniden President HR2510 radio and will key any amplifier with relay keying contacts. The RBI-1HS is isolated by an internal 1 megohm resistor, so there is NO POSSIBILITY of damage to your radio from our circuit if properly installed! The only way any damage could occur is if you did not install this correctly! ONLY YOU are 100% responsible for correct connection, we WILL NOT be liable for any damage to your radio for any reason! Our box will draw <0.1 ma from your radio connection point and will key any amplifier. A completely unique product! RCA jacks in and out for keying the interface from your radio and output to your amplifier T/R relay control Needs 12 VDC at only 60 ma, use the SAME 12 VDC power supply as the one that powers your radio (this is how the input gets it's ground) or just connect the INPUT shield to ground on your radio if you use a different power supply for the RBI-1HS and your radio. Output relay rated up to 240 VAC at 5 AMPS! Genuine relay used for switching (not an easy to damage solid state device) Color of RCA cables may vary *Can be used with any radio that you can find a point that will switch from 0 on RX to 3-12 VDC on TX See our eBay store listings for our complete line of Amplifier Relay Buffer Interfaces. In other listings we have models with 2 radios and a bypass switch, 2 or more amplifiers or other device (like noise reduction unit keying, mute, etc) When connecting your Radio and Amplifier, there may be switching voltage, polarity, and current incompatibility that can cause damage to your radio or amplifier if connected without a switching interface between them. Even if your internal radio switching looks like it might be usable, it is wise to have an extra degree of isolation between your amplifier and radio with our relay buffer interface. 73, Dan W7RF ( Radiodan ) Ham Radio amplifier amateur amatuer radio amplifier relay buffer interface
