This did not work for me as non-Premium account. I wonder if works differently for RR's Premium Subscribers? I recently had this same question. Do not have Premium, so can't login. Tried "Get Data", didn't receive new info. As example, Connecticut's CLMRN Trunked system shows Troop G as
RFSS 1(1) Site:21(015)
while the
live db here shows
3(3) and 013(D)
The software keeps the Offline files in this folder
C:\Users\All Users\Unication\RadioReference
I tried uninstall >> wiping leftover Application Data and System files >> re-install. The files re-appear, but they're dated Aug 6, 2020. The whole offline folder is 65 MB of .csv files, I wonder if they're packaged with the installer and dated to around last time PPS was updated. Either way, I can't get them to update.
