I have a new pro-106 and radio schaak was not much help with software but i found "radioreference to be great ! The problem im having other than to be out of the scanner loop for a few years is I cant seem to upload my "choices or anything from the 20-047 usb cable that radio schaak sold me it says "timed out" or "check connection!" Im pretty confident with my computer but maybe the drivers are not installed properly or this cable does not support the pro-106 they told me it would even though it does not list it . Does anyone have the same problem? or do you recommend an alternative?? I did try to download the drivers online also and using the disk but to no avail! and also using the adapter plug and not the plug 3" extension for stereo/headphones etc. Thanks for any help.....Happy new year to my new scanner buddys!!
