2023年4月7日 · No, OpenSky is IP based (kinda sorta like wifi), meaning you basically need a radio to be connected and registered on the network to be able to listen or transmit on said system. Your better off waiting for the system to reach the end of life so they switch over to the new P25 system

2015年10月21日 · OpenSky radios only have a minimal amount of programming in them (basically the bare bones system info). When powered up they log into the system and get provisioned over the air (as previously mentioned, what talkgroups it's allowed to access etc etc).

2011年9月19日 · Status of OpenSky monitoring efforts The main reason we won't seen OpenSky capable scanners sold anytime soon is due to licensing and intellectual property issues surrounding DVSI's AMBE vocoder. I have conducted considerable research on this topic as I reside in Pennsylvania. I believe the only possibilities for dedicated hobbyists are as ...

2023年12月25日 · Merry Christmas! This is my first Project Opensky Airbus livery! Major changes have been made since I uploaded my latest livery. 1. Mipmaps have been removed, 2. I added much more accuracy and detail than I used to before, and 3. I now use Model Converter X to check if my livery is alligned.

2011年5月24日 · I heard they had the OpenSky radios back then and were training with them and found out they were not “intrinsically safe" so they sent them all back, and Harris loaned them some VHF radios. Only MFD had OpenSky during the exercise at the airport, there were a lot of other Suburban depts there too who were using Milwaukee County 800 radios.

2011年7月4日 · Here's a screenshot of a live OpenSky signal in Austin Texas on 935.7 Mhz as viewed through UniScope. There's a remarkably clear eye pattern. Apparently OpenSky is C4FM at 4800 baud (much like non-simulcast P25). That's 9600 bits per second. [ insert evil mad scientist laughter here ]...

2004年5月28日 · OpenSky is a digital radio system sold by M/A-COM. It uses a two-slot TDMA transmission method in 25 kHz bandwidth with an aggregate data rate of 19.2 kbps. The airlink protocols are based on modified CDPD.

2010年4月4日 · OpenSky is a digital radio system sold by a division of Harris (formerly a division of M/A-COM). It was introduced in 1999 as an expansion of the Monarch wireless voice and data system built for FedEx. OpenSky uses a four-slot TDMA transmission method (four-level GFSK modulation) in 25 kHz bandwidth channels with an aggregate data rate of 19.2 ...

2011年8月16日 · Opensky is significantly more efficient in terms of frequencies - there are either 2 or 4 talkpaths per 25kHz channel, where P25 trunking provides 1 talkpath every 12.5kHz (or every 20/25kHz at 800MHz) so you have significant capacity issues, and will need more frequencies (and thus channels on combiners/multicouplers, etc) and the coverage ...

2018年6月5日 · Oakland County, Michigan decided to go against the state-wide standard decades ago and chose MA-COM OpenSky for reasons I won't publicly speculate. Inadequate unreliable coverage plagued the system putting countless lives at risk. I think they underestimated the number of tower sites required...
