Looking into Uniden

michal.gordon@...
 

Hi everyone. 

I'm looking into getting into Uniden. Any thoughts or tips on how to go about it?

Thanks,
Michal

Maybe we should push the media – actually, don’t some of them get to listen in on encrypted stuff too?

You would think that in these times LE would want to be transparent (in the clear). I'm surprised the media isn't pushing that issue.

They have been pushing it.  But protecting the tactical nature of many LE operations has won the argument so far.

It wasn't Law Enforcement.  LE in Orange county has been full time encrypted for MANY years.  Fire was not.  When they migrated to the P-25 system, fire got changed to encrypted - without (as I understand it) anyone in the fire organizations knowing that was going to happen.  There was a huge backlash from the fire agencies to switch fire back to clear.  Law still is encrypted.


I know a bunch of Scanner enthusiasts don’t have that kind of clout…


Got that right!

LE encryption needs are debatable; though there ARE a few specific times to encrypt (undercover, SWAT).  Encryption doesn't lend to the open public view of the agency and tends to cause mistrust in those that want to listen in (what are they hiding?).  It shouldn't be debated here in any case (waste of expelled vapor, time or effort).

When fire needs to encrypt (even more rarely) it's often punted to a cell phone (arson investigation being primary)

Being able to clearly listen to both not only makes interoperability simpler (cross agency/discipline) it also allows the general public a little more lead time when something goes down, shelter in place for active shooter; start moving the livestock for an evacuation and even the mundane; to be aware of events in/near your neighborhood (Sam is drunk again and slapping his wife around; fire/medical down the street and these days 'peaceful protestors' creating havoc) to react appropriately.  Having spent a career in fire, being situationally aware is in my DNA.

I will add that requiring dispatch to either relay to another dispatcher or set up a link (patch) between radio networks, has not exactly worked well for LE.  I'm in N ID, within 30 miles of two state lines and the country border, listened to a FUBAR 3 state high speed chase (100+), a mix of analog and P25, some unencrypted, a 4 agency 'blend').  WA(SP) to ID(ISP) to MT(SP) with Shoshone and Kootenai counties, almost all on disparate systems... a comms disaster; they ALL had to hear/talk to each other... and couldn't.  The perp eventually ran out of fuel, just before MT (big hill, twisty climb) and got pounced on.

Having the switch to quickly turn off encryption (better 'spatch training too) would make such cases so much better for LE and safer for the public (catch the miscreant quicker) since (my point in this story) most LE vehicles (here) also have scanners (to bypass the middleman and hear directly).  Encryption denies LE (public safety) to better do their job.

Not just scannerheads, but news media (MUCH harder to track to scoop), amateur radio ops (inter-related on safety issues), off duty fire (gotta listen to be quick on that OT call) and smaller groups like neighborhood watch.

Again, I've not heard that they relented, only that they were going to relent.  I'm a thousand miles away so I don't listen.

If memory serves (sometimes it does), OC went encrypted last year.   There was much hue and cry from various sources and OC relented to not use encryption.  However I've not seen any mention of the network being heard since then; some issues between vendor and buyer, it became political, slowing the entire process.

If it is still encrypted, you won't hear anything.  By now, the database should have picked up (and corrected) any change of frequencies.

If memory serves correctly, and with my age getting up there, that’s a question! But I think I remember reading that many complained that they encrypted fire, along with everything else. People who lived in wildfire areas, and monitored fire comms via scanners were very upset. OC relented. 

But I could be very wrong about this, so don’t take this as fact.

Not sure what an 818# means. If you mean a frequency of 818 MHz, that is an input frequency and is not used on scanners. Use the output of 863.

At that same time the Countywide System was nearing 10 years old. Each organization in the County that is a stake holder had to put in their share of the infrastructure cost. Nextel paid its share of the total cost. The stakeholders opted to update the entire system including handhelds, base stations and our share of the system front end including, antennas, microwaves. I retired near the end of planning.

Looking at the Radioreference data for Orange County

 

It appears that almost all talk groups- Law Enforcement and Fire are encrypted which means that no scanner can legally hear these communications.

 

The exception looks like Anaheim and most area's public works have some unencrypted T/G.

All the radios are the same.  An encryption key is loaded into the program information loaded into the program mask.  So since I had a radio issued to me county communications could load all the channels that I was authorized to use.  If the radio had a problem they would take a radio off the shelf load my radios template and I was done.  One side note If I needed to talk to a unit from another City or Organization, notice the colors and how they are used.  The Chief of Police or head of an organization has to sign off on anyone having access to his system.

FYI Richard

 

The entire country had to reband to trade cellular frequencies for Public Service frequencies.  I thought that the deadline for this was years ago?

 

If your 436 was OK'd by Uniden, it means you already have the firmware upgrade that was released to handle the rebanding (or they did it while they had the radio).

 

I don't think your problem is rebanding, I think it is encryption of talk groups.

 

Your system has multiple transmitters so you need to have (at least) the control frequencies for towers close to you programmed.  If you do, the radio should periodically stop momentarily (maybe make a garbled noise) and resume scanning when someone transmits on an encrypted talk group.

It was for most of the country. Orange county California is within the range of the Mexican border that re-banding required treaty negotiations with Mexico. That took years, so most of the 800 MHz systems in that border area have fairly recently completed their re-banding.

Law enforcement on the Orange County system has been encrypted for decades.  When they went P-25, fire got switched to encrypted.  That was not desired even by the fire chiefs, but it took a while to switch back.  I do not know what the status of moving fire back to clear is (I don't normally monitor anything in Orange county).
