No worries!  Glad you were able to resolve.

FPP supports controlling a USB attached relay board as a normal GPIO output in FPP.  If you search the forum for "usb relay" you should find some posts with links to known-working relay boards.  I have one I picked up off Amazon in the early FPP v1.x days.  One of the relays on these should be good enough to switch the power input to your FM transmitter.

Interesting!  Had not thought about doing something like that.  @fauxton had implied that earlier, but I was not familiar with a triac, and had not put it together.  Looks like they make a GPIO power relay that works directly off the GPIO pins as well.  https://www.amazon.com/gp/product/B00WV7GMA2/ref=ox_sc_act_title_1?smid=A3D4241373L385&psc=1  The Synaccess is working well at this point, but something to look into next time.  Thanks Chris!

The rasclock appears to only need pins 1,3,5 (3.3v,SDA,SLC) to function.  Looks like pins 2,4,6 (5v,5v,Ground) are just used for support to hold it on the board better.  I see some have just soldered a wire to the 5v pin on the top of the RASCLOCK board for a fan.  If you are needing 5v fan speeds and want to do your own research, it might be still possible.

Oops....missed your response last month.... :-[

Thanks for the response.... 

Got overwhelmed with this year's show so haven't gotten around to doing anything about a fan....
