While you can't directly download the data from the RR database, you can use MS Excel (or many other spreadsheets) to copy the RR database, modify it to match the Win92 format and past the data into Win92. This should save you quite a bit of time and trouble (and nearly eliminate they nearly certain typos from manual entry).
For example, copy the data from "LA County FD Battalion Response Map", which will look like this

Copy the "Frequency", "Tone", and "Alpha Tag" columns into a new area of the spreadsheet. They need to be reordered and an extra column added. The final destination should be "Alpha Tag", "Frequency", (a new column added called) "Rx Mode", and "Tone".
Next, edit the "Tone" column to blank out the "CSQ". For those entries, populate the "Rx Mode" column with the text "FM".
Next, edit the "Tone" column to remove the " PL" from the columns that have this populated (e.g. "151.4 PL" would become simply "151.4"). For those entries, popluate the "Rx Mode" column with the text "PL".
Now that the data has been cleaned up and is ready for loading into Win92, it should look like this:

Next select the 4 columns of data (but not the headings row) in the spreadsheet and copy them (ctrl-c or appropriate). Move to Win92 and select the row where the first of them is to be placed. Plaste the data onto the Win92 screen and check for any errors. Correct any errors and populate any options from the 4 columns we didn't populate.
Repeate this process for the other banks and save the file locally (so you can simply make changes later if needed) and upload the data to your scanner.
Please note that the amount of data you can copy is limited by the Win92 screens (which reflect the scanner limitations). You can only copy up to 50 frequencies per bank. To descide what values to enter in the "Rx Mode" col, simply look at the Win92 values for that field and pick the one that's appropriate. While I didn't provide details, you can populate the talk groups for trunked systems using a similar procedure.
