Add the Tuner Genius PTT OUT to the Band Settings panel.

K5CG

I recently added a Tuner Genius XL to my shack with a Flex 6600 transceiver and a Gemini DX1200 linear amplifier. I was using the RCA TX1 output as the PTT for the amplifier so that I could have the amplifier PTT and "exciter" RF power out set to a lower drive level by a profile selection. Going back to a barefoot profile would just not key the amp but at higher power.

After inserting the TGXL into the line I had to move the PTT for the amplifier to the PTT OUT of the TGXL. This was the only way to prevent the linear from keying during a TGXL tune cycle.

It also meant that could no longer use the RCA TX1 output as an option in Band Settings to prevent me from keying the amplifier accidentally at full power from the 6600. At least, I haven't found a way to do that.

I described this problem and an interlock solution that I am going to build here.

Feature Request: In a perfect world, there would be an additional column of checkboxes for the PTT OUT on the TGXL in the Band Settings of SmartSDR so that I could selectively key the PTT OUT (to the amplifier) from a profile and still exclude it from a Tune cycle of the TGXL. Another option would be to add a setting to the TGXL software to mirror one of the existing RCA TX# outputs so I could use it as before.

I put a SPST in the amp keyline. It sits next to my keyboard. I just need to remember to switch it off when the TGXL tunes.

For that matter I could manually put the amp in standby mode. I still want control from SmartSDR.

Hey Guys,

I have a similar setup , I have a flex 8400 , TGXL and a palstar la-1k amp.

I want to control the amp via smartsdr profiles and the TX1 rca jacks.

I have my amp looped through the TGXL and it seems to work ,but its "always" in line.

My last attempt was to set the PTT source to RCA and loop through a PTT from TX1 to PTT in on the TGXL , that seemed to work ,but .....

now I get a NO PTT in when I switch to the default profile which does not engage the TX1 port.


I spent a week in a facebook forum and another week with a flex helpdesk ticket, I got nowhere with either.

Sadly flex was no help and gave me wrong information and pretty much didnt want to help.


this should be a standard setup, be able to control the PTT line to the amp.

did anyone find a clean way to get this to work? no double through relays or manually disamping the amps ......

thanks
