Does 3.7 include the new CW keyer option for bug emulation?<br>
I have not been able to use CW on my ANA 100-D since I bought <br>
it last year because of the "no bug" feature. After a call by me<br>
and others for this albeit dated feature to return, it was
eventually <br>
and gratefully implemented when the CW keying was moved into <br>
the FPGA firmware code where it properly belongs.<br>
<br>
I heard that earlier firmware release bugs (software kind)
turned<br>
out to be internal soft coded FPGA micro-timing issues, i.e.
things<br>
like FPGA register settling times, etc. One should remember that<br>
each individual FPGA has its own distribution of timing
requirements <br>
and also depend on temperature, supply voltage, etc. Possibly
then <br>
only some of the ANAN's with atypical timing behaviors exhibit <br>
this "dead-keyer" bug.<br>
