Does anyone know if frequency tuning is supported via SB9600 for any radios? I know there are a number of third party products that use SB9600 to interface for various purposes - is anyone aware of any that do their own frequency tuning or what capabilities exist beyond those available from directly from the head?

IIRC doesn't one of the frequency agile aircraft radios use XTS-5000s, or parts derived thereof?

I can tell for sure that MC2100 & GM1200 and their portable counterparts can be almost totaly controlled via SB9600.
By sending an SB9600 command, radio shows "CSQ" (carrier squelch?) just like when programming.
Beyond that point, radio is totally paralyzed, awaiting your (SB9600) will...
You can control display, operating frequency, ptt, illumination, etc, to name some.

When I was designing at Wulfsberg/NAT we were looking at using it in some early prototypes of a P2000 derivative radio but it was terribly slow with the display lagging seconds behind a command.


Like Paul mentions the other radio features are bogged down by the 9600 bus commands.

There are a number of Motorola radios that utilize the SB9600 data bus to have external control of the radio itself.

By "external control of the radio itself" do you mean actually tuning to a specific on-the-fly frequency via SB9600 - or simply changing the zone/channel like you would otherwise do from the head? The remote control heads themselves usually use SB9600 for control of the radio - but I'm not looking just to emulate the capabilities of the head.

If it puts this more into context, I'm mainly interested in SB9600 in relation to Astro Spectra - but background regarding other models is very helpful as well since little of this is documented.

To my knowledge there are no commercially built radios on the market that allow you to actually enter a new frequency set via the SB9600 bus. That would also be against the FCC rules regarding several types of services.

Like I said earlier, there is the ability to emulate the functions of the control head to change channels, zones, scan, monitor and the like as well as to be able to display the current channel info that the radio would normally display on the control head.

Well, I don't think that it's a matter of FCC, since every RSS programmable radio should be illegal as SB9600 is used for the programming of the radio.
IMO it's a matter of mom M what features a specific radio should have.
As I mentioned above, JEDIs like MC2100 & GM1200 can be literally turned upside down using SB9600 including the actual operating frequency,
although I'm not sure whether they are FCC type approved.
On the other hand, ICOM IC-V100, that IS type approved, needs just an external keypad (no electronics at all) to alter it's operating parameters,
much easier than dealing with SB9600.
I think that FCC cares just for one thing: End-user should not be able to alter his radio's licensed features without some kind of special tools.
It could be a good idea to check with my MTS2000, but although I have warned my friends about toolproofing, I toolproofed mine!
