W4/VP9KF N1MM+ Logger tips page (By the way, I refuse to use Windows 10)

Latest information, support and questions can be found on the N1MM Logger+ Yahoo Group [with nearly 3,500 members]
Latest updates are announced on the group every Tuesday morning, or more frequently if required for bug fixes.
It helps everyone if you test a new version between Tuesday & the weekend when you are going to operate. Report any problems so that they can be fixed [from Tom, N1MM].
ONLY REVERT TO AN OLDER VERSION IF THERE IS NO FIX BY THE TIME YOU CAN NO LONGER WAIT ANY LONGER.

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.

Please remember that the N1MM+ Logger code is written and maintained by a group of volunteers. It's tough because of the vast number of transceivers, support devices, modes and versions of PCs and Windows that are supported all at once. Some troubleshooting is recurring and is not easy to find on the Yahoo Group 'archives' [lets out a groan]. Hence these notes. Some problems are difficult to reproduce without many hours of their time.
