If I'm recalling, that was supposed to be plans for a statewide data network on 220. I don't know for some reason thats what I'm recalling. I think it was around the same time they were beginning to dick around with Opensky. I think it now resides in their FCC files where renewals are blindly shot off as the recently renewed lowband license at a local station with no lowband antenna
I seem to remember something about that statewide network from 12 years ago.
The bandwidth is actually very high for "narrow band" communications. This product (that I designed) allows for the maximum allowed bandwidth allowed by the FCC. In almost all cases, the bandwidth is limited to 12.5kHz. With the 220 MHz band, it is limited up to 50 kHz bandwidth just like the datasheet for that product shows. Show me a product with higher bandwidth that passes part 90 rules? I will show you a product that didn't pass part 90 rules. Why is everybody trying to erase everything I ever did lately? Did I kick you dog or something? I love dogs btw.
In my "previous life", I did take a job where I was responsible for "finishing" the previous guys "big idea for a QAM-64, 12.5 kHz receiver". That "big idea" took him out and I was able to get that done and eventually passed by Part 90. Yes, I am the first guy to get a high-power QAM-64 modulation in a 12.5 KHz channel to be "a thing". They fought me on it, but I was hired to get that done. I think one other company passed something similar at the nearly the same time as far as when it was "expected", but I beat them by at least 12 months in terms of submission. I believe the whole reason for the delay was to "wait for their buddies". Ask me for the FCC / ICC identifiers if you think I'm not telling the truth. The grants will all show my name. (until they change it).
LOL for an Ham or GMRS, or other civilian maybe. Only if the end is nigh will you see Public Safety agencies go grab an Baofeng, Anytone, or an TYT MD380 etc... There are just too many other layers in place for this to happen unless its a truly SHTF end of the world event. Hardened to an point LMR, sometimes collocated or even linked to LTE, IP based purely data systems, then the civilian Cellular/LTE nets, not to mention the still in use Satellite Radio and Telephone systems... Not disparaging, but just stating the facts. Especially after a few Public Safety agencies caught heat for using Ham radio a few years back. Not to mention all the layers of bureaucracy that would never play nice enough to let that happen. Not to mention, how many patrol officers, or firefighters can grab just any radio, and on the fly get it where it needs to be to talk by FPP? If it can't be as easy as turn a knob a few clicks, or press an up/down button and then PTT.. Its going in a garbage can.
Interesting. Any idea on make or model?
From what I recall it was data only, no voice. I don't know if they still use it or not.
