P25 One-Frequency Trunk vs. Conventional P25
Jul 12, 2010 · One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
Frequency went P25e and not sure what I need to enter
COSO channel 1 is P25 phase 1 (P1) LSM modulation. It's the LSM (same signal from multiple towers) that your scanner has a hard time with. The only Phase 2 (P2) system in central wi is Dane county's DaneCom trunking system which runs both p1 and p2 talk groups. He steered me to the wiki link on simulcast.
P25 Simplex - RadioReference.com Forums
Dec 8, 2019. #8. The considerate thing is to review what the coordinating body for each area has designated. Northern and Southern California should be fine with 145.080 MHz for P25 simplex or any other simplex digital mode. For UHF, 433.080 may or may not be an issue in So Cal, but should be fine in northern California.
Can Baofeng's be used to listen to trunked systems?
Messages. 3. Mar 23, 2024. #1. I am trying to find a way to listen to trunked systems, specifically a project 25 Phase II, using my Baofeng BF-F8HP. All of the PD, Fire, EMS, and even local University use this P25 Phase II, is there anyway to program my radio to be able to follow these systems. Or do I have to get a radio that is specifically ...
P-25 Input Frequencies/Inbound Trunking - RadioReference.com …
04-762.00625- (+)30.000-12.5. The first object in the hash is the Channel ID, second is the Base Frequency, then the offset shift direction, offset and finally the channel width. In my example I provided the basics for a 7/800 MHz system which is advertising Phase 2 capability (though may not be utilizing Phase 2).
P25 One Frequency Trunk Programming - RadioReference.com …
Nov 14, 2013 · However, P25 CAI (Common Air Interface, another name for "P25 audio", essentially), also carries the numeric ID of the radio and the talkgroup. So technically speaking, it is like a trunk, but one without a control/data channel. If you program a frequency as a "one-frequency trunk", you can receive not only the audio transmissions, but see the ...
Can I listen to a frequency that is p25 on Boafeng UV5RA
Sep 5, 2014 · Location. Victoria B.C. Canada. Sep 6, 2014. #5. You can listen to it, but you won't like it much. Technically I believe P25 is not a modulation, it is just a method of encoding voice digitally. It can be broadcast on FM or AM, but will sound like noise unless your receiver can decode it. Normally it is broadcast over an FM carrier. J.
P25 channel ID tables - RadioReference.com Forums
Nov 11, 2022 · 0x09157562 + (0x612) x ( 0x064/2) x (.125 Khz) <- let's translate this to decimal and shift to Hz for simplicity. 762006250 + (1554 x 100/2 x 125 Hz) = 771718750 Hz, or 771.718750Mhz. Keep in mind, VHF/UHF will follow a different rule set for calculation (if memory serves). chrismol1 said: With the channel ID table that includes base frequency ...
General discussion question on P25 - RadioReference.com Forums
Aug 19, 2024 · So whether it's an old analog system or a modern P25 Phase II system, it's really nothing more than a repeater with an input frequency and output frequency. By the way, P25 Phase II (and other TDMA systems in general) has some features that are not available with non-TDMA systems, such as true subscriber preemption.

Mar 22, 2024 · The first thing to do is to let us know what agencies you plan to listen to in your area so we can better answer your questions. That said, a scanner capable of receiving only P25 Phase 1 will not decode Phase 2 transmissions. And, if some of those agencies are Simulcast, then only an SDS 100/200 would be your choice.
