Hey all, I finally picked up a 436hp today and and very impressed out of the gate. I bought from a local Ham Radio Outlet which is about ah hour from my house, typed in the local Zip and immediately I was getting everything in the area. Police, fire, EMS… it was great. So I got it home and started to program it with Proscan like I’ve done with my 325P2’s in the past. Got the hang of programming using favorites and spent a few hours getting all the frequencies in the software. Went to upload to scanner and hit a few roadblocks. First, the scanner has a serial port, but no serial cable. No problem, I had a spare cable and connected to my PC. Couldn’t seem to get it to communicate with PC. Swapped out the serial cable for the charging cable. Got it to communicate and the graphic in the Proscan software was showing what the scanner was showing. Perfect. Went to “write to scanner” and I got an error message. Something to the effect of “must select a line”. There was nothing to select. I could not get past this, it’s like the scanner wasn’t being recognized when trying to write my programming file to it. I don’t have the specifics now because I’m not at my computer, but I assume it has something to do with putting the scanner in the correct mode “mass storage, usb, etc”. Can anyone point me in the right direction here? When I turn on the scanner when it’s plugged in, it asks me to make a selection regarding USB mass storage. I never press anything and let it time out and start scanning. Should I be selecting something there? Thanks all.
