You could try something like W1AEX to accomplish some sequencing pattern.

Hi Alan, Here is a link to the ARRL IC7300 review article that I found on the internet.? It was in the August 2016 issue on Page 41.

Thank you Alan. [email protected]> wrote:

Dave, That link takes me to the 7300 group IO home page but cannot find the RF tail fix. I do not own a 7300 but have a few friends that do which each of them seem to get things confused so I end up

Guys, I ordered that board from Tom. Thank you for all the help etc. As far as the 7300 goes, I thought all that was adjustable in the menu??? Bob W4JFA [email protected]> wrote:

Robin, Here is a problem that may be similar to yours: https://www.eham.net/forum/view?id=topic,112624.0.html I had the shorted Q2 problem as well in my Centurion. 73 Bill N4LG PS: Another problem is

Many amplifiers have a watch dog circuit that avoids the amp relays from being hot switched. Many amps will delay the closing of the relays until the PTT signal is present and no RF is at the input.

I find that really hard to believe. That means that using a 7300 with ANY amplifier - even a modern tube or solid state amp - would allow the 7300 to hot-key (or hot "un-key") the amp? This would mean

Sequencing is required for some rigs. The classic example is the ICOM 7300 which releases the amplifier key line before the RF goes to zero.? See QST review for IC7300.? In this case, sequencing is
