6000 series control for LDG external autotuner?

I have an LDG Z100Plus semi-auto tuner that does not self-detect high VSWR and autotune itself.  To tune, one must either manually push the Tune button on the front of the unit or use a simple ground-to-tune cable from the transceiver.  Is there a way to get Flex 6000 series to trigger this kind of tuner whenever the TX-enabled slice is moved "enough" to warrant a tune operation?

On my 1000 PROII, unless the swr is above 1.7, it won't auto tune. Also make sure it is in auto mode.

The Z100Plus is a simple small box with latching relays that draws no power when not in a tuning cycle.  It doesn't have an auto mode -- it expects a human or transceiver to tell it to perform a tune operation.  The only "auto" feature of this device is the 2000 memories for recalling previously tuned frequencies.

I don't believe the 6000 series radio have any way to trigger your tuner automatically.

For remote operation, a 120v relay plugged into a wemo mini wireless switched outlet may be your best answer.

The idea being you would energize the relay, which would kick off the tune cycle.

If you use a wemo switch, they are supported by Apple HomeKit, which in turn is supported by SSDR on iOS software.

Good luck, Ken

To expand on my first paragraph, the 6000 series hardware does not have an IO pin that is under software control that could be used.

I suppose, if you aren't afraid of voiding your warranty, I buy something could be rigged off the internal tuner board connections - of course, such a device would have to convince the radio the board was installed, then somehow capture the ATU signal to retune as needed.

Might be best to consider an upgrade/replacement tuner.

A little more cumber-son way (maybe) to do this may be to connect the TUNE button on the tuner itself to PTT1,2, or 3 RCA outputs jacks on the FLEX and build a TX profile to set the transmitter to low power out with PTT 1, 2 or 3 to be activated then select a normal TX profile with out that PTT enabled and the Power where you want it.

Simply switch to the Tuner Profile hit tune on SmartSDR then change to the normal Profile and your ready to go.

Using this same setup but may be easier,  you could also in the TUNE Radio profile set the Mode to the AM or FM modes, this way just Key the MIC to start the TUNER tuning then switch the Profile back to normal TX.
