Yes, it works!! I had my first contact on the analog birds (AO-7A) running
a modified Yaesu FM transceiver.
I disconnected the MIC preamplifier circuit, I kept the Tx activated and
switched the PA drive transistor by a switch circuit added and commanded
by the CW key. Despite the tone was FMing a bit, I had some contacts.
