Batboard

Will be getting ready to move up to Astro Sabers soon. Being a "new" guy I will most likely be asking more questions in this regard. Our FD is moving to a splinter channel shortly so I am doing the leg work to make sure the we are ready for Dayton. Radios to buy you know. Batlabs has been a great help, thanks.

What is the minimum DSP revision to assure splinter channel operation on Astro Sabers?

Yes the AS3 does do splinter channels 12.5K spacing with 2K deveiation. I got a whored out Nick flash, works great on the 470 splinters.
I believe all AS3 in the UHF cut will do splinters - even the earlier flashes.
I assume you are talking about UHF Astros
