It's 7C in the shack tonight so I decided to set up the IC-705 and use it remote from the warmth of the house. The client software on macOS is SDR-Control and I was using AirPods bluetooth headphones.
Even running just 10W reports were all good although Graeme, VK3NE, mentioned a bit of boomy audio.
The main issue is the delay when switching between receive and transmit - I doubled with other stations several times. It was mentioned that my final words of an over were chopped off so I think that I need to not switch back to receive for a few seconds after ending what I was saying - perhaps there's an audio buffer to send.
The IC-705 is an amazing radio and it's great that 10W with a good antenna is enough to be easily heard by other stations. Joe, VK3MAB mentioned that I was 10dB over S9.
