Your interface can also be used with PTT control in CW by simply setting the "Digital" port RTS to "PTT". In addition, the three transistor interface will work fine with a USB to serial converter and MMTTY's EXTFSK driver.
The interface is essentially the same as documented by AA5AU on his RTTY web site: http://www.aa5au.com/rttyinterface.html 73, ... Joe, W4TV On 2/25/2013 8:34 PM, bills stuff wrote:
This is perhaps rather a special case and may have been addressed elsewhere but others may be interested. I developed an interface and setup for the K3 to use N1MM and MMTTY for both FSK (not AFSK) and CW using a true serial port. This allows quick switching from FSK to CW and back with no hardware changes in the N1MM DX mode. Radio control requires another serial, or USB converted to serial, line of course.
