Hanford The Flex 3000 has a relay build into it. It can key 250VAC at 2 amps. There is no need for an ARB 704. In fact, the relay in the radio is likely better than the one in the ARB704.
Just to be clear. In most Amps all you do to put an Amp into transmit is to connect the PTT line from the Amp to ground. Very simple. We often connect a Henry 2K Classic directly to the Flex 3000 without any interface. Just the RCA to RCA PTT cable from the radio. Adding another relay just inserts more failure points and more noise. :) Those that do all this doom and gloom on amp keying are not clearly understanding the technology.
