Hello,
It looks like someone was listening to this system as well and posted some useful information. I was going by North Stonington, CT so I hung around for about an hour this past weekend monitoring the system with LTRDump. Unfortunely I had a data glitch delete some data so I was not able to get all the site 102 frequencies.
In the database the 02 and 03 frequencies listed for the #1 system belong to another site. The 02 frequency of 452.0750 is actually used in the #2 system in the database. So the police are on system #2. That is one advantage of using LTRDump. You get an idea what channels belong to what systems. The problem I had was not listening long enough to get some of the non-home repeater numbers. I hope to get down to CT soon and give another listen.
This is a 4 Site Passport system with a majority of radio traffic being Regular LTR. Passport supports Regular LTR as well. You need a program like LTRDump/LTRTrunk to decode and track any units using Passport instead of Regular LTR.
The FCC database shows four trunked sites along Route 2 from Ledyard to North Stonington. One site by the Casino, one site by the Museum, one site on top of Wintechog Hill (shared with VoiceLink site 80), and one site near the junction of Route 2 and I-95. I noticed some frequencies are not shown in the FCC database.
Marcus did both Voicelink and this system so I find it interesting that the original VoiceLink sites are numbered 10, 20, 30, 40, 50, 60, 70, and 80. This system has sites numbered 90, 100, 101, and 102. Marcus seems to use unique site ids for passport systems it sets up. The maximum number of sites in a network is 127 (1 to 127). It is possible that Passport radios on this system can also use VoiceLink but I have not seen any indication.
I did not monitor any Passport activity other than CW IDs from the repeaters. This system may be only using Regular LTR radios. Site 90 is so very active that I may have missed some Passport activity. I did not hear any voice activity on sites 100 or 102. On 451.225 MHz (Site 100) I did pick up some transmissions as Area 1 Channel 1 but it sounded like a distant LTR system.
Passport does not use repeater numbers like Regular LTR so the Rptr entries are for Regular LTR. The LTRDump logs allow me to determine what Rptr numbers are used in the system.
