Unidentified Talkgroups
3205 - Talkgroup 3205 seems to be some sort of Emergency Management agency. Noted 6 RID's on 7-12-22 starting at 1000 hours, discussing radiation measurements around US 30 and US 67 along the river, and reporting them to Stockton (They actually used Alpha type geographic points but alluded to both highways). RID's were 18040 to 18085. TG was open. Also noted on 09-07-23. Again noted on 02-27-24. FEMA was mentioned several times. All monitored on Scott/Muscatine site.
4210 - Fully encrypted - heard on multiple sites in eastern and northeastern Iowa. RID 3868, 3880, 3842
4212 - 4214 has been in use on the Muscatine/Scott sites. Fully encrypted, the RID's range from 3842 to 3956. These RID's correlate with those used by DPS probation officers in Region 6, ISP District 12. 05-26-23
4235 - TG 4235 encoded usually 4 units check in daily in PM or if active several times a day. Radio ID 3999 3989 3995. Could be a small agency of a few units with a local office. This tg is in daily use but not listed here. Usually do not hear this on the Vinton tower just the Cedar Rapids tower.
4270 - Fully encrypted - heard on multiple sites in eastern and northeastern Iowa. RID 15000081, 15000083, 15000093, 15000104 [Verified as MedForce, Quad-Cities] 5905 - UID 467001 467169
9017?
20155 - county? UID 1004980
07-08-22 TG's 4150 & 4171 - RID's 15001202 to 150001207 (so far). RID's consistent with non Governmental ISICS users. Referred to a substation in Sperry (in Des Moines County). TG's were open. Logged on Muscatine/Scott site. [4171 is Eastern Iowa Electric & Power, Wilton]
7-10-2023 Not sure I have submitted these or not. From my notes, Talkgroups 4200, 4212, 4214, 4235, and now today, 4236. They are all encrypted. The Radio ID's I have logged are all consistent with State radios: 3800 through 4111. For example, State 'G' cars (probation officers) use radios in the same range.
