+ AA6YQ comments below
1a. what CI-V address have you specified in the Radio panel ?
IC-7100 and 88 hex address
1b. in the PTT panel, with the radio connected to an antenna on a clear amateur frequency, do the TX and RX buttons work?
Yes
2a. which buttons in the Mode panel work correctly?
LSB, USB, CW (normal), Data L (wide), AM (wide), Data U (wide). Other modes are not operative (and not present in the G106)
VFO A, VFO B, A=B, A x B, XFC, Split
TX, RX
Frequency control with the mouse, and 1, 2, 5 10 quick split
2b. in the Filters panel, do the Group, Width, PBT1, and PBT2 controls work correctly?
The Xiegu G106 is a minimalist QRP rig, and has only 3 CW filters (50, 250 and 500 Hz). The filter Group has no effect on them.
The G106 has only a standard SSB filter, and no PBT.
+ Many thanks, Georges!
