REPEATERS:

We have several VHF and UHF repeaters on the air in the greater-Winnipeg area. They are as follows:

Output: 147.015 MHz
Input: 146.415 MHz
RX Tone: 127.3 Hz
TX Tone: 127.3 Hz
P25 Digital NAC: CAC
Deviation: 5 KHz


Output: 444.975 MHz
Input: 449.975 MHz
RX Tone: DPL 664
TX Tone: DPL 664
P25 Digital NAC: CAC
Deviation: 5 KHz
Notes: 1) IRLP node 1553 is connected via a half-duplex link radio.
2) This repeater has no hang-time enabled.


Output: 444.9375 MHz
Input: 449.9375 MHz
RX Tone: PL 88.5 Hz
TX Tone: PL 88.5 Hz
P25 Digital NAC: BAD
Deviation: 5 KHz

Notes: 1) IRLP node 1822 is connected via a Motorola DIU3000 (Digital Interface Unit). All P25 traffic on this repeater is encrypted with AES-256. This includes IRLP communications. The IRLP link is NOT accessible on analog. This IRLP node accepts incoming calls only. This repeater is a test platform/installation for future network expansion.


Output: 927.0125 MHz
Input: 902.0125 MHz
RX Tone: DPL 664
TX Tone: DPL 664
P25 Digital NAC: CAC
Deviation: 2.5 KHz (narrowband FM)
Notes: Please use "HearClear" noise-reduction settings in analog programming configuration.


SECURITY & ACCESS

Our repeaters operate in three modes: Analog, digital and digital-secure. We are publishing the keys required to participate on our machines in the digital-secure mode. You will require your own compatible radio(s) and other associated equipment to communicate on our repeaters.

CONFIGURATION, PROGRAMMING & MAINTENANCE:

Please ensure your communications equipment is properly aligned and calibrated before using our repeaters. We take great pride in the quality and maintenance of our network. We ask that you utilize recent firmware with audio gain control (AGC) enabled, if possible in the programming configuration of your radio(s). If you require a firmware update or have questions, please email service AT p25.ca for assistance. This referral is NOT associated with Key Communications Inc.

Our ASTRO/P25 network will soon be digitally patched together via V.24 wireline interfaces. The first priority will be linking the UHF and 900 MHz stations. VHF will soon follow. Analog patching is also being considered, however it's a LOW priority.

In attempt to better organize our infrastructure, we ask users to adopt the following P25 Radio ID (RID) ranges:

VHF: 1000-1999 (If you're a new user, please use a value above 1200)

UHF: 4000-4999 (If you're a new user, please use a value above 4200)

900: 9000-9999 (If you're a new user, please use a value above 9200)

System infrastructure such as DIU3000s will utilize Radio IDs above 3000000.

Changes to the network are scheduled to be completed by the end of 2011. Updates to follow.
