Has anyone have any idea as to who the encrypted signal on 858.9875 in the MSP block of frequencies might belong to? Signal was heard around 6:45 PM on 5/28/20.

Any talkgroup numbers? If it's something like 3665, 3605 it may be the msp radio techs on the CoMIRS p25 system, but I believe you are referring to the legacy system which has different talkgroup numbers. Keep in mind msp uses trunked radios so the frequencies for voice may change around after each transmission or so, so it is not fixed on one frequency which means the frequency you identified 858.9875 may not help much

No TG numbers showed up. This happened on a scanner where I had simply programmed in that particular frequency. This scanner is a PRO-106 on a Discone in my attic. I have a Whistler 1040 that has the MSP system programmed in by computer. That scanner is on a 7 inch flexi type antenna. Nothing was heard on the same frequency at the same time.

Without a Talk-group hard to Tell

MSP do have some P25 Voice Talkgroups on the Analog system
and in Zone 5 they did allocate that Freq to be Analog and P25 [Mixed Mode]

Those are TG's from the ComIRS P25, those would appear on the Analog as 3665*16 = 58640
if allowed on the Analog side

On Zone 5 there were ONLY two allocated Mixed Mode channels out of the 10 available for Analog
