Key your RIG using FLdigi's new SERIAL PORT DTR/RTS CW RIG keying feature

[Chuck aa0hw]

The accuracy of having FLdigi key the RIG using its new serial port DTR/RTS keying circuit ...looks impression on first testing...

TESTING  at          120 wpm,  150 wpm and 200 wpm      sending the number    5

the GREEN WAVE on each is the SERIAL PORT RTS PIN keying a tone oscillator representing the RIG's CW JACK...the RED WAVE is the resultant RIG CW sidetone after actually being KEYed on its CW JACK by the serial port simple circuit (a transistor grounds the jack etc...)

120 wpm

150 wpm

200 wpm

here is a LIVE VIDEO TEST of the keying the RIG's CW JACK using the FLdigi RTS/DTR serial port method...    runs from 50 wpm to   101 wpm

uses the RTS pin in this example testing from 50 wpm to 101 wpm SCOPE on both the SERIAL PORT CIRCUIT and the RIG's CW sidetone to compare how each look and see how accurate and consistent the QRQ CW TIMING is when keying using a SERIAL PORT and a simple transistor keying circuit to connect and key the RIG's CW JACK http://www.w1hkj.com/FldigiHelp/cw_dtr_rts_keying.html
