Gary I got it now and works.... The first command you sent me now works.... I was not sure where to put the .ini file so I copied it to two locations.... bad on my part, I forgot about that so I deleted it and now everything works great. Thank you for all your help and all the help you give to others. Hope to work you some time. 73 Barry KY4K

@irad d Well.. it worked for everyone but me. It did not work. BTW frequency changing and PTT ON/OFF work. The command you gave me was the same string that was already in there. I put a # in front of the command and added yours just in case. Here is my file: [Icom IC-9100] CmdType=HEX PTTOn=FEFE7CE01C0001FD PTTOff=FEFE7CE01C0000FD ModeUSB=FEFE7CE00601FD ModeUSB_D=FEFE7CE01A060101FD #ModeUSB_D=FEFE7CE01A060101FD #For different USB-D filters, Replace ModeUSB_D value with: #Filter1: FEFE7CE01A060101FD #Filter2: FEFE7CE01A060102FD #Filter3: FEFE7CE01A060103FD ModeFM=FEFE7CE00605FD SetFreq_Data_method=BCD SetFreqVfoA_Cmd=FEFE7CE005{}FD SetFreqVfoA_param_length=10 Any other ideas?
