I just received my DEMI transverter for 70 cm. DDutil and CAT did not recognise the frequencies between 432 and 434 MHz in my banddata file. I had to edit the "CatClasses.xml" file. I changed the upper limits for the "ZZFA , ZZFB , FA and FB" commands to 500000 and after that is was no problem anymore. My USB and LPT relay cards now recognise the band and are distributing the PTT command to the SPE-1KFA , the DEMI 2M75LPDA and the DEMI L432-28HP in the correct way. Can this file be updated in the next SSDR update ?
