I cannot seem to download the files from the database into my PSR-500, it says I dont have a premium subscription because I have to have the scanner offline to free up the com port. When I have the feed online it allows me to access the database which locks com port 3, its a catch 22 it seems. I was thrilled to get the psr-500 today and was looking forward to getting it up and running. I have been at it now for 6 hours and I am to the point that I am about to send the radio back. Could someone point me to a specific reference, I have looked at usb cables, connector cables, I cannot find info on what mode the radio has to be in to recieve the frequencies from the database. I would appreciate any asistance you may give. I have tried both PSR Edit and Win500 with the same results.
