|RBI-1||Relay Buffer Interface
Put this little box between your radio's amplifier keying output and your amplifier "relay" input to completely isolate your radio from your amplifier. Draws <3 ma from your radio keying circuit.
Will key ANY amplifier T/R relay up to 200 VAC at up to 3 amps!
Ground on "input" will provide closure on "output" connector.
RCA jacks in and out, 3 feet of wire for 12 vdc (total draw from your 9-15 VDC power supply is only 40 ma!)
|RAP-1||Receiver Antenna Protector
Install this little box between your receive antenna and your radio's receive antenna input to protect your expensive radio from the RF that your receive antenna picks up from your tansmit antenna. Don't gamble with your radio's front end! Damage to your receiver front end can be expensive and take time and shipping costs to fix. This little box is cheap protection! An internal relay completely removes the receive antenna (center AND ground) and places a 50 ohm resistor across your receiver terminals during transmit. Needs 12 VDC and a keying signal to ground from your radio (can also be used with an amplifier keying as well). We suggest 2 RCA cables (below)
