Below is a compilation of the data recorded today driving through Sussex from Bridgeville to Selbyville. The FCC site is slow tonight, so it's going to be difficult to correlate with physical sites.

Site 19-19 Felton (Formally Dagsboro) - seen in Bridgeville area
771.25625 cch
772.18125 acch
772.58125 acch
773.23125 acch
Peer / Neighbor sites: 15-15 Seaford; 21-21 Georgetown SBA; 25-25 Unknown

Site 21-21 Georgetown SBA - strong in Georgetown
773.03125 cch
773.28125 acch
773.53125 acch
773.78125 acch
Peer / Neighbor sites: 19-19 Felton; 23-23 probably Georgetown SCI?

Site 23-23 Georgetown / SCI? (carrying SCI traffic) - strong in Georgetown
770.15625 cch
770.40625 acch
770.65625 acch
770.90625 acch
Peer / Neighbor sites: 21-21 Georgetown SBA; 25-25 Unk? (using 770.80625 as cch) ; 27-27 (new) Dagsboro

Site 25-25 Ukn? - seen in Bridgeville area
770.80625 cch
771.35625 acch
771.90625 acch
773.70625 acch
Peer / Neighbor sites: 19-19 Felton (old Dagsboro); 23-23 Georgetown / SCI; 27-27 (new Dagsboro)

Site 27-27 (new) Dagsboro - strong in Dagsboro
771.78125 cch
772.60625 acch
772.88125 acch
773.15625 acch
Peer / Neighbor sites: 25-25 Ukn? (using 770.80625 as cch) ; 23-23 Georgetown / SCI

It's going to take some more work to flesh this out.

It does appear that the Seaford site number has changed from 15-15 to 25-25. Site 19-19 Felton was reporting site 15-15 (old Seaford) was using 769.15625 as a control channel. 769.15625 was assigned to site 09-09 Dover / DSP, so it looks like the Dover site is now site 15-15. Hopefully someone can confirm this.

I’ll drive through there in the morning on my way to work and try to check.

Remembered to grab a scanner on my way out the door this morning. Got signal on 769.15625 as soon as I got on route 1 from frederica on-ramp site 15 nac 00fh signal held until Smyrna

This site passes a lot of traffic statewide. I’ve never heard so much before. Lots of traffic in the clear as well

Along with Dover/DSP becoming Site 15, Smyrna is now showing up as Site 13, and Middletown is Site 11.

After monitoring for about 30 minutes, the Dover/DSP site is as busy as @chrishoerner mentioned with a lot of traffic from statewide DOC facilities. Just as I was typing this, I saw a Phase II affiliation on several of the JTVCC talk groups on the Smyrna site only. What could that mean?

I've been locking onto some talk groups prior to the ENC skip, and I'm definitely seeing TDMA (Phase 2) talk groups off the Smyrna Site. Is it worth it to track and make submissions to the database with the majority of the system being encrypted?

ENC talk groups can be submitted IF they are properly identified.

Thanks for the clarification @maus92! At the current moment, TDMA is showing up on some of the existing DOC-1x and 2x talk groups. I’m just curious if Delwin is a Phase 1 or Phase 2 system.

If you see TDMA, then it is a Phase 2 system. There will probably be a mix of both Phase 1 and Phase 2 subscribers for the foreseeable future as each agency is responsible for ordering and deploying radios. Motorola has supply chain issues fulfilling orders, especially with mobile radios.

The 700mhz system is Harris I believe not MOT like the 800.

You can run Motorola radios on any P25 system - you are not locked into any one vendor. The state has a deal with Motorola; not sure if the 700 tech refresh deal with the Harris vendor includes subscriber radios or just infrastructure.

Well yeah duh it’s a P25 system. But I remmebr reading that the DELWIN infrastructure was awarded to Harris somewhere and a buddy in DoC says they’re using Harris portables so I wonder if they’re trying to get a mix of vendors in there

So following up with everyone else's contributions, I traveled most of Delaware on a recent trip, and have noted the following changes: (yes, I submitted the info below to the database already for inclusion)

Site 1-1 Claymont is now: Site 3-3 NAC: 003 Peers: 5-5, 7-7
Site 3-3 Wilmington is now: Site 5-5 Wilmington area NAC: 005 Peers: 3-3, 7-7
Site 5-5 Newark is now: Site 9-9 New Castle NAC: 009 Peers: 11-11 (location change, tower located at Intersection of US 13 & I-295)
Site 11-11 Middletown: change NAC: 00B Peers: 9-9, 13-13
Site 11-11 Hartley: 700 MHz site not on air currently and remove old site number 11-11 designation.
Site 13-13 Smyrna is now: Site 13-13 Smyrna-JVTCC NAC: 00D Peers: 11-11, 15-15
Site 13-13 Felton is now: Site 19-19 NAC: 013 Peers: 15-15, 21-21, 25-25
Site 15-15 Dover HQ: change NAC: 00F Peers: 13-13, 19-19
Site 15-15 Seaford is now: Site 25-25 NAC: 019 Peers: 19-19, 23-23, 27-27
Site 17-17 Milton is now: Site 21-21 NAC: 015 Peers: 23-23, 25-25
Site 19-19 Dagsboro is now: 27-27 NAC: 01B Peers: 23-23, 25-25
Site 21-21 Georgetown is now: 23-23 NAC: 017 Peers: 21-21, 25-25, 27-27
Site 35-35 JTVCC is now: Site 7-7 Wilmington area NAC: 007 Peers: 3-3, 5-5

This information is confirmed as of July 28, 2023 and needs some tweaking. If any of the locals can check the Wilmington area for tower locations for the new Site 5-5 and new Site 7-7, that would get this system up to date for the most part for new site designations and NAC's. Most talkgroups were secure mode, but a select few still in the clear. The information above was verified with Unitrunker and the antenna removed from the scanner at each location, except for new Sites 3-3, 5-5, and 7-7. I'm almost certain that Claymont is 3-3, but 5-5 and 7-7 needs verification. Note that while traveling through Newark, I did not pick up a strong 700 MHz signal in the area. Perhaps the site might be off the air still or moved?
