How to add a 4th TX output to 6600?

Rick N0VT

I have a Flex 6600.  I have an HF amplifier connected to the TX1 output and an antenna switch connected to TX2.  I want to add two transverters to the mix. Since the 6600 only has 3 TX outputs, how do I juggle my connections?  This surely can't be as simple as a "Y" adapter on one of the TX outputs, can it?

Pin 11 on accessory is accessory tx. check it to see if it will work for u.

Looks promising, Thanks!

Otherwise you could use a powerdivider for TX and use  aux rx + xverter rx for both transverters. Then finally you can switch the PTT for the transverters with a switch  ( or banddata ) to decide which xverter sends .  I did something similar long ago using 28-29 for 2 meter and 29-30 for a 70cm xverter on ONE exciter.

I have the exact same situation.

I solved it by using a "Y":

Then I configured a Flex USB BIT cable to pick up a relay:

The relay  adds 12 VDC power to one of two PTT Opto isolated solid-state relays, one for each of the two transveters:

The Flex USB Bit cable is configured to energize the relay based on the active TX slice's band selected.

I took the K. I. S. S. route, using Terry's suggestion. I had an old 15 pin monitor cable in the junk box that I cut one end off of and replaced with a Rca male plug wired to pin 11. Works great!

Good choice!
