expert 1ka what exactly is needed

Ian1 Member ✭✭
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. Ian

    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.
