That's what I was thinking. Download the free version of Win500 from starrsoft.com, upload the frequencies from the 106 into it. I believe that it can save as a CSV file. If not, simply 'cut' the frequencies from the WIn500, paste into an Excel table and perhaps save that as a CSV file.
Then get Win97 from starrsoft, arrange the columns in the legacy 106 CSV to reflect those of the Win97 interface, and resave as CSV and see if it imports. If not, simply cut and paste the "rows" of the 106 CSV spreadsheet into the Win97 interface. I used this system to get all the freqs from my Pro-95 into my PSR 500 and from my PSR 500 system into my Pro-160. It's more about adjusting the Excel files (and getting rid of digital channels and incompativel settings) than anything else.
I should all that while you can use the Starrsoft programs for free on a trial basis, you really SHOULD pay for them it you plan on continuing to use them.
