Amazon Rochester

[k2hz]

The Amazon.com-ROC1 fulfillment center is now in operation. Should be conventional UHF DMR license WRTL760.
The only possible activity I am hearing is 463.600 but it is too weak to decode.
I am probably too far away and Amazon likely to only be heard in the Gates/Greece area.

The Amazon.com-ROC1 fulfillment center is now in operation. Should be conventional UHF DMR license WRTL760.

"Grand opening" or not, it's actually been in operation for months. I plugged the eight frequencies into a scanner last December and heard activity right away. I listened for a couple hours then stopped.

The only possible activity I am hearing is 463.600 but it is too weak to decode.

Did you mean 464.600? I don't see 463.600 on the license.

I am probably too far away and Amazon likely to only be heard in the Gates/Greece area.

The facility is right on the Gates/Ogden town border, so Ogden too, probably moreso than Greece.

I'm less than two miles away, and have picked up traffic on all 8 frequencies in the last 30 minutes or less. I should reprogram them as OFT and see if there are multiple talk groups in use on each or just one. Each repeater is using a different color code.

Not sure if I have patience (or interest) enough to figure out what each repeater is used for.

 

[k2hz]

Yes, should be 464.600. I had been checking periodically and heard nothing so I tried again with the official opening.
I was wondering if many frequencies would be data rather than voice given the nature of the operation.

8 repeaters means they are probably using the standard 8 frequency, 16 channel conventional radio system. Unfortunately some people have identified the system as "trunked" when it's not and have submitted it to the DB as such. It's all conventional. I've monitored about 8 or 9 of these systems and they all follow the same protocol. With the lowest licensed frequency being CC 06, or 07, to the highest at CC 13 or 14., each one one step up. The lowest frequency will use 6100/1 and 6200/2, and every frequency will be the next talkgroup up, (6300/1, 6400/2), all the way to 7500/1, 7600/2 on the upper end. (In one case, I know of a system where they are NOT in frequency order for some odd reason, but everything else remains the same).

So here is an example of how Rochester may likely show. (Again, not set in stone. But very likely. Needs confirmation.)
FQ DCC-TG/TS1-TG/TS2
463.3250 07-6100-6200
463.4750 08-6100-6200
463.7000 09-6100-6200
463.9375 10-6100-6200
464.0500 11-6100-6200
464.2875 12-6100-6200
464.6000 13-6100-6200
464.7750 14-6100-6200

 

[sallen07]

Definitely conventional. You're not going to have an 8-frequency trunked DMR system with a different CC on each frequency!

Here's what I have so far. Pretty much follows the pattern you suggested except that CC 14 got stuck in the middle somehow.

Frequency CC
463.3250 7 6100
463.4750 8 6300 6400
463.7000 9 6500 6600
463.9375 10 6800 6808
464.0500 14 7500
464.2875 11 6900 7000
464.6000 12 7100 7200
464.7750 13 7400

The TGs are the ones I've seen in the last few hours. Sorry that the formatting sucks ... it looks fine in edit mode but once I save the post it squishes things together again.

I'm using a BCD996P2 for this right now. Is there a way to see the TS? If not, can an SDS200 show it?

I suspect the Amazon sites are all the same and the Oxnard CA site seems to be well documented as an example:

Subcategory: Production/Warehouse Facilities/Amazon Fulfillment Center (Oxnard) (Businesses)

Standard set up for all Amazon centers around the country, one TG for slot one, a different one for slot 2 and different color code on each frequency, just like

 

[sallen07]

Works for me.

Are any of the repeaters IP linked and do talkgroups "float" between repeaters? Known as poor man's trunking.

All info from other Amazon sites is conventional fixed TG/slot on each repeater.

That TG 6800/6808 does not look right. CC 13 should be 7300/7400 CC 14 7500/7600. That frequency order is they way they appear on the FCC application. 464.050 is listed last.

BCD436/536 and SDS100/200 show slots.

In all the systems I've monitored, they do not. It's just straight forward One TG per slot, frequency.

 

[W1KNE]

Definitely conventional. You're not going to have an 8-frequency trunked DMR system with a different CC on each frequency!

Trunked systems can have different color codes on different frequencies. It's rare but I know of at least two systems near me where this is the case.

 

[k2hz]

I have added the site to the RRDB with each TG listed as just Warehouse Operations pending any submissions of specific TG use.

 

[sallen07]

The last four frequencies are wrong. Should be:

464.2875​	11​
464.6000​	12​
464.7750​	13​
464.0500​	14​

Sorry for the horrible format!

 

[k2hz]

It wasn't your format. We had discussed the frequencies out of order but actually in the order as appeared on the license. I did a couple of cut and past things to enter license info in the DB and then went back to enter the CC/TG/SL. I didn't see that RRDB had put the frequencies back in normal order before I entered the other info. Hopefully it is fixed now but I had to be careful how I entered the data and let RRDB keep the standard frequency sort.

 

[sallen07]

Ah makes sense. Yes, looks good now. Thanks!!

I am seeing a few other talkgroups but my guess is that they are decoding errors and not real.

From a 2020 FCC filing by Amazon in another license...Note the first line where it says it applies "for all of our new Fulfillment Centers.".
