Had 6600M about a week now.  Tried it with KPA500 amp today.  For some reason, RCA TX1, RCA TX2, and RCA TX3 are not keying.  I have them all enabled on the transmit page.  If I connect the cable directly to the amp and short the cable, the amp keys fine.  I put a VOM on TX1, TX2, and TX3.  They measure about 30 ohms to ground.  Nothing happens when I key the rig.

Any ideas what I might be missing?

In case anyone is following this thread, the problem with RCA TX1. TX2, and TX3 ended up being hardware.  I worked thought the Help Desk at Flex and they send me a replacement radio.  Everything (including TX1, TX2, and TX3) works great on the new radio.  Thanks to Flex for their prompt response!
