Digital Radio Protocols

I know it has been many clock cycles since I last made a post here but hoping to have more to post here during the next couple of months as I endeavor to get a better understanding of the different digital radio formats and protocols being used, especially the ones I am having to work with on a daily basis.
Here later with the influx of many projects at both my real job and part time job I am having to get an understanding, in addition to Astro 25 I now have to learn and understand Motorrbo. And since I have always had an interest in D-Star I figure I would include this also. I am also having to understand Digital Spread Spectrum now as we’ll, which should be interesting just from how Spread Spectrum propagates from the preliminary info I was given.
So this will be the first of what I hope will be an informative ride into digital radio and get a good and better understanding for myself as well. There are some things I am hoping and wanting to do and hoping as I gain a better understanding I can see if what am I am wanting to do is already inherent within the protocol. One I already know exists in both Astro25 and Mototrbo and interested in getting a better understanding is OTAP (Over the Air Programming) which would make updates less labor intensive once setup.
So, as I gather up the info there will be more posts here along with photos where possible. Until next time….73s!


Mototrbo Application Development

First off, I see that the photo that was uploaded on the previous post was formatted/displayed weird, but if you click on the “partial” photo it will display the photo correctly. First time I have added a photo to a post sent via my Blackberry.
Took a few moments this afternoon to do a little searching on app development for the Mototrbo radios and I did find a Mototrbo Application Development Kit Overview pdf document on Motorola’s Mototrbo Application Development Program site:

I already have a Motorola Online access so I can use my current login to at least access this level, but I found I would have to register as a business & developer to get more access to the tools and info at least from my quick looking around. Will do some digging through the site and the things I can get access to with my current login credentials. I am also hoping to get access to the Mototrbo CPS Developer version to see what all it has compared to the normal CPS. The link for the Application Development Kit Overview document is at:

As I dig a little deeper and learn more I will post updates.

Until next time….73s!
