N1MM Logger+ is fast becoming the 'go-to' software for small and large DXpeditions. If you are running a small operation, I would recommend you use DX mode. It contains differences in comment, look-up and other features. For larger operations, use DXpedition mode to minimise satellite data upload sizes, etc. |
The first thing is to go into Windows
audio configuration and TURN OFF
Windows sound generation. There is a good technical reason for this if
you are using the PC's serial port for keying the transmitter. The second thing is to slightly reconfigure the COM ports. Go into Windows Device Manager [if using Win 10, select Control Panel/All Control Panel Items/Systems/Device Manager], select Ports(COM & LPT), then at each Com port, select Properties/Port Settings/Advanced. Then find Rcvr (bytes) and set it to 64; then select Tx (bytes) and also set it to 64. Change 'Latency Timer' to 1ms [NOTE! This depends on the specific RS-232 COM type device, some have it and some don’t]. This will improve the speed of your USB/Serial devices and help eliminate CW stutter. |
