TSA?

Two things... Since its the US Government it's probably encrypted. And how close are you to the airport? You might need to be very close.
Where are you listening from? Keep in mind the TSA usually works inside the airport utilizing low powered radios. At RDU airport I can not hear the radios more than a quarter mile from the terminal.
While TSA does have encryption it is not used everywhere or on all radios, it is really hit or miss with the TSA.

No - Not Correct. Years ago the TSA moved to a unique NAC per Airport and ceased the common uses of $001, $002, $003
That said, remove the NAC from your programming and if around the airport [the system was engineering for On-Site coverage, so don't expect much distance from it] see what you get.
some airport have moved off 172.9000 to other channels, and there is a nationwide move [altho very slow] to go UHF [which will even more decrease the distance heard from the airport]
As to ENC, it is selectable per radio and the use will vary by User, Airport, Time of Day and any security issues/Operational Tempo as determined by the User, Airport or their Supervisors.

13 miles roughly

I would say at that distance you have no hope of hearing them.
Greetings...
I use to live about 2 miles west of KMKE airport and if the weather was right, I could pick them up. The few times that I did actually hear them using the radio, it sounded like 'simplex' to me.

There used to be a TSA repeater in New Berlin.
May be worth sniffing around the NTIA subband to see if it still lights up, but I don't listen to fed traffic since it's 99.9% encrypted.

Can't you just use NAC $7FE?

That feature works with a REAL Two-way radio, but not a Scanner.
Yes you can listen without the NAC, but then you also could [YYMV] have to deal with near-by [dueling] airports of other users on the same Freq.
ie: I have a VA Hosp that is on the same freq as one of the CBP Air-x channels.
And we also have ICE authorized for a Repeater on the ole 172.9000 TSA [former FAA] channels - with a unique NAC
And having the NAC is many time a Confirmation of who it is.

i used to work near Punta Gorda airport in Florida.
i used a uniden 396T and had all the TSA freqs in it.
if i was inside our building, i could not hear them.
outside was spotty at best.
i was across the street and around 1000 FEET away.
so you would want to be closer, to hear handhelds, than that.
when parked in the parking lot i got more transmissions.

The move to UHF has happened in WI.

Are you sure it is TSA? That sounds more like a USPS freq/mode

If it's in the clear, I too would have to guess that it's the USPS. They have that monster sized facility just to the southeast of the airport now.

TSA is P25, not DMR
Could this be a near-by USPS Sorting Facility or VA Hospital ?
What CC/SL/TG are you getting ?
