When you are drowning in the ocean before we can send a rescue ship, here is a lifesaver to help you in the meantime.
This is based upon an UV-5R Chirp file for another drowning soul:
Step 1: Open your UV-5R file in Chirp
Step 2: In Chirp, go from File to Export to CSV and save the file with an appropriate name.
Step 3: Open the CSV file in a spreadsheet program, such as Microsoft Excel
Step 4: Using Cut and Insert Cut Cells move the following Rows so that they align with your Baofeng UV-5G+ software:
Location, Frequency, rToneFreq, Offset, cToneFreq,
Step 5: GMRS Repeaters are always +5 MHz Offset, so for bonus points, you can create a new Row named Tx Frequency and in the topmost cell for Row E (Tx Frequency), insert the formula: = B3 + D3 RETURN and the populate the formula by copying cell E3 to the remainder of Row D. Then you can cut and Insert Cut Cells to move the Offset Row to a later point in the spreadsheet and now have a Tx Frequency Row instead.
Otherwise, when the time comes, you can just manually adjust the frequency Up 5 MHz, such as 462.550 to 467.550.
Step 6: Go to Row B in Excel in the first GMRS Repeater you can to move over and copy its contents - Rx Frequency. Then paste it in the appropriate cell in Baofeng
Step 7: Repeat Step 6 for Rx CTS/DCS, Tx Frequency and Tx CTS/DCS
Not the greatest solution, but a solution nevertheless.
GOOD LUCK!
Ignore Row 2 in the Spreadsheet and Rows 31 and 32 in the Baofeng software.
