rebanding

I have a question. In the article habpatol linked to, it said i will have to replace my BC785D. i am assuming this is because i the freqs programmed into the scanner for the"control channel only" mode will be wrong. What if i program all the new freqs in manually once they are known? Is it just the Control channel only option that will be obsolete in monitering the Tulsa DPS system or my whole scanner?

-thanks

The problem, as I understand it, is that the freqs are referred to by a Motorola channel number, not the actual frequency. So, when the control channel says (in effect) "All units on TG 44444, go to channel 308", the scanner knows that, accoding to the Motorola channel plan, channel 308 is 859.9875 MHz. When the PS 800 MHz band is reworked, all the freqs are going to be renumbered, so channel 308 might become 855.3875 Mhz. Your scanner won't have a table with the correct channel number to freq list, so when the CC says to go to channel 308, the scanner won't know to go to 855.3875 MHz, it will go to 859.9875 MHz. That applies whether the scanner is in CC mode, and selects the frequency; or non-CC mode, and the scanner has to locate the scanner channel with the freq that corresponds to the Moto channel number. Only a few of the latest scanners will be able to be reconfigured with the new table.

Note, the above is a very simplistic explaination, and all numbers & freqs were made up for the example. Please, all you trunking experts out there, don't email me and say "you're wrong, channel 308 is actually 8xx.xxxx MHz".

Hope this helps. It took me awhile to understand this myself! :lol:

Then they have to move out of the way. (Yes, it is confusing)

Go to www.800ta.org and READ.

It is all there.

that answered my question, thanks K5MAR. I guess i will continue to used my 785, then when all of this goes down i will get me a new scanner. Any suggestions on handhelds that won't be affected?

Phil, I believe only the top of the line Unidens (396T and 296?) and the Radio Shack Pro-96 are likely to be upgradeable. Myself, I'm forgoing all scanner purchases until all the dust settles. Neither Uniden nor RS are making a 100% guarantee that they will be able to implement the rebanded trunking (in current scanner models), just in case Motorola throws a curveball at them. The first rebanded systems should come online in about a year or so, then we'll know, for sure. I know, it's a long time to wait for new toys! :lol: But that will give me time to save up for replacements for my three 780s.
