I just bought an IC92 at the Belton, Texas Ham Expo that was held yesterday. I have been using dstarcom and chirp to work with the files as well as open office CALC to modify the files.
The 92 has a provision for exporting memory channels into CSV files in blocks of 100 memories. The sequence of fields is different between the 91 and 92. I opened both the first 100 memories in the B bank (A vs B for analog vs digital) and decided to cut and paste. Every time I tried to import the modified file back into the 92 I got illegal file data error from the RS92 software. Two reasons: 1 - Open Office CALC defaults a Text Delimiter (" that is masked) as well as the comma delimiter (separator between fields) AND 2: The Location field (memory number) has to have a leading edge '0' in the first 9 locations. I used notepad to put the leading zeros back and when opening the file in CALC set the text delimiter to blank. Hope this saves someone some time and frustration. No tremendous differences between the 91 and 92 thus far - more power settings and slightly different display beside the WX proof case - I did not buy the GPS mic and forgot to buy the protective case. 73, Steve NU5D PS - Sure would like to see CHIRP go forward - lots of potential..sb
