THREE radios keys TWO amplifiers

High quality relay box to interface between any THREE radios and will key any TWO amplifiers or one amplifier and a noise reducer (like MFJ-1025 1026, etc)
Switch chooses one of three radios that will activate BOTH isolated output jacks
Bypass can be selected by choosing an unused or non-active input
Many newer radios can only provide for a small amount of current on the external amplifier keying output. 
The outputs are a closure of contacts.

This is not one of those types that make you use a battery to power the unit! This high quality device is powered by your station power supply or any filtered DC source from 9-15 VDC (only 100 ma required) Need the best DC power supply? See our ebay store for SAMLEX power supplies.

Need to use with 1-6 radios to 1-6 amplifiers (or other combinations of switched devices)? Contact us.

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. Get our RBI
