What makes you think USPS uses it? It's registered to: DRAGOTTA, JOSEPH G. LTR is sometimes used for businesses, which is what it looks like in this case. He probably set up an LTR system and sells the talkgroups to different businesses.

I said it is a USPS system because whoever submitted the info to the RR database labeled it as such. Also, all the talkgroups are attributed to the USPS.
On another note. According to the license info on the FCC website, that particular callsign is only for one frequency pair. How can you make any kind of a TRS with one frequency pair?
US Postal Service is using 854.7625 for their semi truck deliveries to/from the airport terminal. It is indeed a single channel LTR system (One of many in Milwaukee area). They recently moved onto here from 859.6875
