There are still AD9850 moduiles = to be found on Ebay - that are not completely obsolete or sold-out yet.

Write your controller code to switch betwee= n two or three (for DFCWi) frequencies under control of the ON7YD software,= toggling RTS / DTR on a=C2=A0 COM port interface (use an FTDI USB one if n= ecessary)

I am looking for a better method= to transmit DFCW for 2200 meter
QSOs. For my QSO with 2E0ILY I used a QRP Labs U3S for the
transmitter. This worked very well for DFCW60 when I was
transmitting every other night. For any QSO attempts involving quick
change from RX to TX it would be difficult because of the time
required to program a new message!

One possibility would be to modify this method used by N1VF for JT9
QSOs with a U3S:

https://bgelb.github.io/u3s-qso.html

I am a little concerned about messing up my trusty U3S but I may try
that.

It looks like the easy way is the old QRS software by ON7YD. This is
very interesting but I don't have a suitable transmitter. Are there
any published designs for DFCW transmitters which could be
controlled in this way? I wonder if parts would still be available?
I am guessing these used synthesizers which are not current
generation any more. :-)

Any other suggestions?
