I'm sure this has been covered numerous times, I just cant find a thread about it. I just purchased an LDG Z-100 antenna tuner; it works if I hit the tune button in SDR and the button on the front of the LDG tuner. Is there an interface cable specifically for the Flex 6300, and where would it plug into on the back of the radio? Any links or tutorials would be appreciated. 73's K0SWT

no interface and  cables like the icom

the way you are doing is the way it works

I have LDG  AT1000ProII with 6600M and go thru same process before firing up the KPA500

The design behind the LDG is that is does not needs cables. It is automatic.
With 1000's of memories it stores just about ever frequency you want.

MFJ IntelliTuner 993B will tune automatically with any transceiver.

I have the 1000PROII also put on auto and works pretty well. Only thing you can't change is antennas, if you have a all band of some sorts your OK, but if a single band wire on both ports your sol!

I find it astonishing that Flex Signature series does not put out an appropriate signal that can be sent to the LDG tuners.  They are absolutely the best tuners on the market.  That lack of a feature prohibits someone from full use of the Flex.  

I, too, have the 1000ProII - but the auto feature will overdrive the amplifier.  Not worth the risk.

How hard can it be to send an HSEND signal to a tuner?  smh
