I have the FT-857D & PSTRotator combination and in a few select circumstances I let PSTRotator control the tuning on the FT-857D and it works fine. I don't actually use CAT-control for routine linear satellite work because I much prefer to manually tune the uplink so that I can stay exactly on-frequency. (as others have mentioned in the past, the down-side of CAT control is that it doesn't update the radio when you're transmitting... but you absolutely can keep MANUALLY tuning the entire time you're talking)

But it has come in handy when I've wanted to squeak out every possible degree of elevation when making short-duration transmissions -- in particular FM command packet uplinks. When the mic is only keyed for a second or two, you don't drift so far off frequency due to the lack of CAT adjustments during transmit.

So, it's available when you want it.

Does anyone use an FT-857D with PstRotator? Just wondering how Omni-Rig works at keeping doppler up to date.
