I used to be Moto Fanboy No. 1. These days I don't care quite so much. I'm familiar enough with all the major players that I can work with any of them. They all have their strengths and their weaknesses.
I view competition as a good thing. It makes each vendor try to make a better product.
However, when Harris bought out the GE legacy business, they bought ownership of the rolling disaster that is OpenSky and some of the liability for it as well. Their correct response to that should have been to put a total end to OpenSky (I or II) and convert those systems to P25 as a matter of standard policy.
Motorola never managed to make a blunder that was as large, notorious, and damaging as OpenSky was.
Engineers will always design a full coverage system and recommend it.
Salesmen will always try to sell that to their customers.
Their customers will always have their beancounters protest the price.
Compromises will always be made that lower coverage, performance, and price.
The system will be installed and the customer will be unhappy with the coverage when it turns out to be no better than demanded by the amended contract specifications.
Lawyers fight over the scraps.
That's how this industry works.
I am probably biasd by The state of Minnesota choosing Motorola statewide for the P25 800MHz (ARMER) system with nearly every county went with, even the ones in the boonies joined. Some of the counties that did not change were in heavy tree areas lousy for 800MHz and the cost to change out all the squad and portable radios which would be cost prohibited. The MN State Patrol uses it throughout the state where it's feesable and still VHF-Hi where ARMER is not implemented. Their VHF-Hi mobile radios are programmed with a VHF-Hi channel to communicate with the State patrol statewide PSAP in Roseville, MN (a suburb of Minneapolis) when those units come to the Metro area since they all don't have ARMER radios issued to them.
The system is very robust and has worked fantastically when the 35W bridge that collapsed a few years ago using the Interop talkgroups so all the first responders could communicate. They system went though it's biggest challenge to handle all the Super Bowl radio traffic for the game last month. I believe they are looking at logs on system performance for the days and the day leading up to the game. The prelim report is that it worked great with some occasional channel grant delays. Some systems like Hennepin Co. sumulcast has so much traffic that they were once down to only 1 voice channel. I would believe they used most of the alt control channel freqs for voice traffic. As usage increase and Phase I radio's are replaced with APX's at some point Phase II could be added for busy systems if need be.
Except for the usual simulcast distortion that affects a scanner user (Including myself) had to endure but the subscribers radios worked very well. I was out of town but I have a couple of XTS2500 programmed with all the interop talkgroups I could not pickup with my BC996XT. I need the XTS's to listen to the county I live in due to the simulcast system being a tough nut to pickup using a scanner. The issues affect quite a a large listening area even the first responder's 2500's have some difficultly with it. I have heard it first hand from one their radios and the people who say those radio's are immune are full of it. All of my XTS's were programmed with on-affiliate scan and due to the limits on the number of scan list members it makes a poor scanner and mine just sit on a talkgroup for kmy area that is extremely hard to pickup due to the site and being almost the same amount of distance from two diffrent placed sites. It sucks when you live on elevation that tops 1,000ft ASL.
The system is robust and fantastic as system techs and Motorola did a good job in the design and implementing system and it's still going strong after being on the air for nearly 15 years. Owning several models of Motorola radios, their quality is good. One agency uses EF Johnson radios and in my opinion sound awful. That was a must and since the system uses CAI other vendor's radios were approved to be used on the system. In my mind Motorola is the king of all two-way radio equipment. It would be nice if they could have an option for just receive only without the need to affiliate without the use ot the non-affiliate scan method. When I worked in Television, the station had to purchase 3 Astro mobiles programmed by the state with legit RIDS and only the home sites for each talkgroup so they could not affilite on a different site dragging traffic on a site it should not be normally be on. Also no transmit excpt to affiliate when changing to the small amount of talkgroups approved with particular agency and that those TG's were added. The no trasmit as setup in the Zone Controller and the mics were removed so there would be no way to accidentally key up and get a channel grant. Now that there are scanners that do P25 trunking, thoee radios are not used realdbility helpful when a particular TG was needed. When the system became operational there were no P25 scanners out yet. Hopefully the scanner manufacturers are able to design scanners that do not suffer from the wrath of simulcast systems.
OpenSky is junk in my opinion and should not be used for PS comms. The State of Pennsylvania dumped OS in certain areas of the state (I believe the Penns State Police), Las Vegas dumped their OS system for poor performance and coverage and installed a Motorola PI system and have great results. The city of Milwaukee, WI went OpenSky and had a ton of problems and the roll out was slow and since I don't live there anymore I don't know if they are still having issues. Naperville/Aurora Illinois went with OS and with the freqs they have it could in theory support 50 voice channels. Again there hasn't been reports of serous issues public comments on any problems with it. In Minnesota, Motorola was not the lowest bidder on a contract to design the system, but the lowest bit can be ignored if a case of reliability can be considered. Minnesota's (MnDOT, Department of Transportation) "Mother M" the contract and since they were the owners of ARMER they chose a company that build quality systems. Thank got they did pick Motorola not select broken sky. ARMER's interop between agencies are seamless when the crap hits the fan. Motorola P25 CAI systems kick butt.
