please? Help a newb program a rebanded trunk system into a bearcatbcd996xt

[bearcatbcd996xt]

i clicked on the site and i dont see it, is it on a page 2 that i cant find ... j/k bright yellow, got it. i feel dumb for that one, dont know why i didnt expect i could click on the line that looked like a link and was a link.

 

[UPMan]

First time I had seen that, too. I was all prepped to explain that any site with freqs above 866 had definitely not rebanded when I clicked on it and found the much easier answer.

 

[bearcatbcd996xt]

in the DB when hovering the pointer over the typed titles for each talkgroup they also appear to be a link, but you can only access the talkgroup menu by hovering over the arrow next to that title, so i think because of that i expected the other link appearing yet arrowless titles must not have menus or info attached, or maybe i was just not paying attention and am now over analyzing it and need to go to bed nearing 1 am.


anyway if i dont pass out i might come back with yet more questions, im thinking about programming a Project 25 Phase system i think there might be one in multnomah county

 

[UPMan]

Sleep? Still 2 more hours at the office...then maybe dinner and sleep. But, it is only 6pm, here.

P25 programs just like Motorola Standard (actually with fewer options). Just put in the control channels and what ever TGID channels you want.

 

[bearcatbcd996xt]

thank you, i will be doing that system, but first i have just found Portland Bureau of Emergency Communications (BOEC), another type two moto trunk, larger then the last one i just set up so i'll knock this out before i get to the p25

You don't need Goat Mt., just the simulcast freqs. For Wash. county you may want to put in the new west simulcast system as well as the main one.
For Portland, just put in the 4 control channels. No need for custom band plans for this system.
I think Clark county is similar to Portland, but I seldom listen to them. (too much useless chatter).

Hehe. I hear all kinds of interesting stuff here in downtown Portland. I work the late shift doing security, and let me tell you that there is more than enough to listen to on Friday & Saturday nights. In fact I have purposely locked out the OSP on my scanner, because of the fact that there is too much to listen to.

 

[joescanner]

is this also the case for Goat Mountain?, Washington County Simulcast, AND Western Washington County Simulcast,?

DickH's comment notwithstanding (because it is - at least for the time being - correct), yes. Any 800MHz system can use this bandplan, not just the rebanded systems.

Also, in response to UPMan's suggestion to only program the existing frequencies - I recommended that you also include the new rebanded frequencies because they are getting ready to throw the switch. You had the correct math - the 868 frequencies become 853 and the 867 frequencies become 852. This will prevent the scanner from not working in the event the switch happens between the time you program (now) and the time you listen (later).

All eight frequencies would go into one "site".

 

[UPMan]

But, the scanner isn't going to work once the system rebands. He'll stilll have to reprogram the site as 800 Custom and enter the band plan for post-rebanding and have it as 800 Standard prior to rebanding.

Only rebanded systems can use the band plan for rebanded systems...if you enter it and try to scan a system that is not rebanded, you won't hear much of anything.

bearcat339xt,

If still need help let me know, i live south in Florence and would be glad meet up and help anyway i can, let me know. You can email me at kd7pjn@yahoo.com.

Channel numbers from 440 to 559 (pre-RB freqs 862.0000 - 864.9875) were selected to avoid major conflicts. For the most part, it seems to have worked.

In the subject bandwidth (862.0000 - 864.9875) there were roughly 26,350 licenses on Sunday. Of those, 22,269 were "Active", 204 "Expired", 3804 "Cancelled", and 73 "Temporary". 52 of the "Active" and "Temporary" licenses are assigned to public safety trunking systems (YF, YP), belonging to 18 licensees.

For the vast majority of the United States, programming a rebanding bandplan into the scanner is not going to affect reception of a non-rebanded system. At least in the state of Oregon.

In any case, I have the two scanners that feed Clackamas County (one Uniden and one RadioShack) programmed with the rebanding band plan, the system is not yet rebanded, and they track just fine.

All the freqs. in the Portland simulcast system have a 5 in the 4th decimal place and can be monitored perfectly with or without adding custom band plans. Many of the freeqs. in the 9 IR sites have a zero in that 4th place and must have custom band plans entered to track them. Most of us here in Portland only need to monitor the simulcast sites to hear everything. Systems where you live may be different.

 

[UPMan]

The safest "blanket" statement (because it works for everyone, everywhere) is to use 800 Standard (or Splinter) for systems that have not rebanded and Custom w/rebanded band plan for systems that have rebanded. It is possible for either band plan to have partial operation under either condition (meaning some comms would be missed, depending on what frequency they were assigned to).

 

[joescanner]

I'm going to swallow my pride here and state unequivocally that the "right" answer lies somewhere between my original position, and that of UPMan.

The basic rebanding band plan for Uniden equipment is lacking:

851.0250     854.0000    440  +  25kHz
851.0125     868.9875       0   +  25kHz

This doesn't account for other frequencies that may be in use in the 866-869 band. (Granted, and I understand, that these frequencies will not be related to public-safety systems in the future). I found this out when watching rebanding activity on the Clackamas System.

With just the basic Uniden rebanding configuration, I was missing frequencies on channels above 720 - because they didn't fit the bandplan as written. I haven't yet found a catch-all that can be used to completely alleviate this, but was able to get around it in a scanner that only allows three ranges with ease. With a scanner that can use all 6 ranges, it is much easier:

LOW	       HIGH	     OFFSET	+/-	SPACING
851.0250	854.0000	440	+	0.025
866.0000	866.9750	720	+	0.025
867.0000	867.4000	815	+	0.025
867.4250	868.9500	961	+	0.025
868.9750	868.9750	958	+	0.025
851.0125	868.9875	0	+	0.025

With the exception of a few systems in the Mexican Border area (Tuscon AZ and San Diego CA, if I recall correctly), this bandplan will work for any system that is in mid-rebanding (i.e. with some frequencies rebanded and others not yet rebanded, as the Clackamas County, Oregon system currently is).

just wanted to revisit this old thread to say thanks to all you guys, you answered my q's well and helped me greatly,
