good snag taco... shouldn't you be in class learning and not browsing the KC page ;)

Looks like the start of hell for a bunch of people :)


Interesting tidbits start after the fluff on page 33

some points that are possibly bad for the scanner community

Improved spectrum usage – The Network must be able to make more efficient use of the
available spectrum than do the current systems. Typical methods include use of TDMA
channels, reducing roaming through system design and management functions, or other means
to be identified,

This function also includes the ability to effectively “kill” a radio so that it is no longer operational
until and unless a technician re-activates the radio. These functions are envisioned to allow the
dispatch position to control which specific radios are allowed to participate in a talk group or to
function within the system as a whole, all without specialized hardware or tools beyond that
which the position is authorized.

Encryption - Information can be encrypted at will Region-wide using a single model. Encryption
includes both Voice and Data transmissions.

likely ties to encryption only but could also apply to standard communication (IE opensky, IP-Radio)

Key changes – Authorized people, such as dispatchers, must be able to change “keys” used in
secure communications over a given radio circuit from a distant location, This functionality will
acilitate the addition of selected subscriber units to a secure talk group without the need to
physically “touch” the radio unit with specialized equipment.

Over-the-air Rekeying (OTAR) – The Network must enable authorized people to send encryption
keys to radios over a radio channel.


interesting features

Radio low volume limiter – Devices must include a programmable software low volume limiter
that would set the lowest volume to which a radio can be adjusted. With a minimum volume set
(through feature control) the volume range of control can be restricted.


Size – Radios must have a smaller package, lighter weight than current radios and should
have a cellular telephone form factor, if possible. Buttons and knobs must be functional even
when the user is wearing personal protective equipment (PPE).

What are the advantages and disadvantages of continuing to operate, maintain, and repair the current
networks for the next five years without taking steps to upgrade or rebuild those networks during that period?

Not to worry. Most of what you copied and pasted here is already doable.

"We want TDMA, OTA programming, encryption, remote stun, to roam onto other networks, and sexier radios"

yea, I was just highlighting the interesting points that could change matters.

haha great images

Poor Sean....

And in Yakima County -- VHF for all the forseeable future.

Make sure you read about the multi band trunking. There are now radio systems that will allow you to roam between VHF, UHF and 7/800. Build it and they will come....

Omni-Link and APX-7000s, in the future huh?

But you'll have to duct tape 4 radios together...
