[WT-support] K3NG Keyer

[Bob Wilson, N6TV]

Does the K3NG keyer present an FTDI USB to Serial adapter to Windows?  If
so, there are two settings to change in the Advanced Menu to stop Windows
from keying the DTR and RTS pins every time you insert the device.  This
applies to ALL FTDI USB-to-Serial adapters.

See this presentation, *slides 26 to 28*, also linked from my QRZ.com page

Then maybe you don't need the capacitor?

73,
