IFEMS has NO encryption in use. IMPD, and MCSO do have encrypted TGs. IFEMS is very busy non stop most days. As is IMPD. Hamilton County is using encryption now on EMS to ER TGs (29 Med) per the 'cut sheet' for programming per IPSC that I have seen. Madison County as far as I know is still in the clear also on FD, and EMS.
If anyone can do an dedicated monitor of the HamCo MED TGs, and confirm encryption, I will change it over to E in the DB.
