Ordered a Expert 1KA today should be here Friday. I have read all the posts and understand I will use ddutil 3.0 to control Expert via computer.

Purchased a RS232 to USB from Array solutions but will that key the Expert amplifier or is RCA PTT or ALC needed.

Flex manual warns about using ALC.

I'm looking for a straight answer not somone asking if I read the posts because I have.

I have a 2k

Use RCA to key Amp PTT

DDUTIL passive serial port to send frequency data for 2K

Check DDUTIL for 1K as setup is different

Do NOT use ALC

Use DDUTIL,to set power

Mine works 100%

Ian, DDutil should be your friend definitely, this util is natively support 1K-FA via interface, all others options as Howard said please.

I key a 1K through the RCA port. 

Heads up - the 1K has an inline tuner that's still activated on receive.  It's sharp enough that you cannot monitor multiple bands using your transmit antenna.  The 1K has a separate multiband receive antenna port, which is useful if you have a separate broadband receive antenna.

I'm told the 2K switches the tuner out of line on receive.  Other than the tuner issue, the 1K works great with the 6K.

Thanks for the excellent response time and answering my question.

Traveling on business this week so I wanted to make sure I ordered what was needed.
