Amplifier keying cable for Elecraft KX-3 radio to your amplifier keying circuit
See our eBay store listings for our complete line of Amplifier Relay Buffer Interfaces. 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 |
