Ok so its been a decade since my last scanner. Computer interface very cool. The programming cable that I was advised to purchase is a R.S. 20-047. The pro 433 is not on the list of compatatible scanners but they said it would work. There is a small pigtail that converts the jack from what appears to be from 3 wires down to 2. Can someone tell me if the pigtail should be hooked inline? The software seems to only load the cable itself and nothing to do with the scanner. I was advised that this disc would allow me to pull freq. off of the internet and into the scanner. This does not seem to be the case. After some research it appears that another program will be required. Any suggestions??Maybe im wrong but it seems like I should be able to give my zip code and select what to download on the scanner. Thank you all in advance. If there is another thread with the same old question I did not see it.
