TWO radios to key an Amplifier keying adapter relay interface amateur radio

Description: The perfect accessory for using either radio to key your amplifier! This listing is for our Radiodan TWO radio to key ONE amplifier box that will allow you to use EITHER of TWO radios to ONE amplifier There is no buffer inside this box, it's purpose is to allow either of your 2 radios to key your amplifier. If your amplifiers relay control voltage or current is beyond what your radio can switch, then you need an interface like the Radiodan RBI series Each radio's key line voltage is isolated from the other radios key line voltage, this product is MORE than a simple "Y" (a simple "Y" would put each radios keying circuit in parallel and would not be healthy for your radios!) Box color MAY be BLACK or GRAY (depending on what we have in stock) Your radios amplifier keying lines must switch low (to ground) on transmit normally to key your amplifier (or your interface box like our RBI-1 series) An amplifier keying line that goes to ground on transmit is the common normal way radios will key an amplifier How to use? Connect the RCA plug into your amplifier "RELAY" jack (or an interface like the Radiodan RBI series), then plug EACH of your radio amplifier keying outputs to the RCA jacks on the box. When you key EITHER radio, the amplifier will be keyed. (The easy way to route the choice of RF from each radio to the amplifier is with YOUR 2 position RF coax or antenna switch, not included) We HIGHLY suggest the use of a high quality Amplifier Relay Buffer Interface like the Radiodan RBI-1 Interface cables for Kenwood, Yaesu amd ICOM available is separate eBay listings Need keying cables for ICOM, YAESU, KENWOOD, Ten Tec or Elecraft? See our eBay store 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. 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) 73, Dan W7RF ( Radiodan ) RCA connector color and style may vary Ham Radio amplifier amateur amatuer radio amplifier relay interface
