King William Co. mobiles licensed for 799 mhz.

New License....King William Co.licensed (WQUU454) for 400 mobiles(all county services) @ 2 Watts ERP on 5 unique 799 mhz. frequencies for simplex operation using ONLY APCO P25 Phase 1 and Phase 2 modes. FYI licensees do not modify their licenses for a new mode of operation unless they intend to use it.

If you thought you had problems previously monitoring the King William Co. SO, EMS, VFD see how well you do monitoring any when they switch to 799 mhz. simplex Phase 1 or Phase 2 assuming unencrypted using 2 watts ERP fed even to a high gain omni-directional mobile antenna.

For a comparison envision attempting to monitor an old 27 mhz. AM mode 100mw CB walkie talkie transmission a quarter mile away. Good luck monitoring King William Co. mobiles simplex on 799 mhz. P1 or P2. You'll need it. Don't expect decent reception unless you are relatively close to the transmission(s) source.

Here's the FCC (WQUU454)link:

There is no such thing as conventional phase 2. Their licensing guy probably just used the emission designators for it in error.

Those are RPC controlled low power channels. They are limited to low power by the rules.

See 90.531(b)(3)

I don't know what Region 42's 700 MHz plan looks like, but I doubt they are meant as system channels.

(And the other poster is correct, there is no such thing as simplex or conventional P25 Phase 2 at this time.)

Yet but I do know /\/\ is working on a conventional phase 2 application and firmware. This can be found. Anyone who attended some of the /\/\ seminars learned phase 2 conventional is in the future but not set to stone.

Is it possible they will be deploying a low power trunk phase 2 from a incident command vehicle like El paso uses during swat and srt operations such as narcotic raids?

Vehicle Repeaters, perhaps?

I'd put money on that. Portables as mobile extenders to the mobile. Didn't think of that but makes more sense.

The frequencies listed in the OP's license link are probably for simplex use. If they were vehicular repeaters they should have used MO3 as the station class instead of MO and they probably would have also licensed the lower 769 MHz half of the channel pairs for the repeater outputs.

I heard something a while back about the school resource officer and dare officer for a grant to get all teachers and staff of the the schools to have radios in case of code blue or invashion of the schools that the staff could have contact with other staff members and resource officer in case of a gun man ,ect on school grounds this could be what the low power radios are for teacher and staff of the school grant threw the kwso. But who nos

700 MHz Low Power/Itinerant
The following narrowband channels are designated for low power use for on-scene incident response purposes using mobiles and portables.
Transmitter power must not exceed 2 watts (ERP). Bandwidth is 12.5 kHz.
Three of the pairs can be licensed for nationwide itinerant use, the rest are subject to regional planning.
There are no nationwide standard names or designators for these channels.

One thing I dont understand with the ems, so ,vfd and wpd its not near 400 people to have all those radios I just cant understand were they are going to . Unless it is the schools for the staft who nos up in the air keep us posted thanks for the info

They could have licensed that many radios to cover all the first line issued mobile and portable radios; all the back-up/reserve radios for when the first line ones break; all the loaner radios for outside agencies that may not have that frequency capaibility programmed into their own radios for interoperability; and for future expansion.

You no after reading how king William has poor. Reception at the northern part of. The county with portable radios and the cars pick in that area fine then the radios could be extenders from there. Car radios makes sense
