Ameritron ‎ARB-704 Amplifier Interface Buffer - Black

ARB-704 a great way to protect your transceiver

Although modern transceivers (mostly) have a teeny relay to effect a contact closure to key a linear amplifier, it’s risky using a direct connection. A better idea is an isolated connection like the ARB-704. Not necessarily cheap, but it’s good and I have one on every modern transceiver.Read full review

If you have an older amplifier get one of these

I’m using it between a ic-7600 and a keathkit sb220
If you use a wall wart to power the unit make sure it’s atleast an amp. Happy Hamming! Kf6tru

An upgrade for pennies would benefit many !

Its Better now ,after I added the second and third RCA jack's
So I could have up to 3 radio's hocked up at a time !
No muss, no fuss, no hassle !
