<tt>Hi All,</tt><tt><br>
</tt><tt><br>
</tt><tt>This is a very belated answer to the problem of not being
able to defeat semi-break in CW in PowerSDR. Hopefully others
will find it useful. For a couple of months I have been using
this solution with a Hermes unit that I am using as an IF radio.
The modification eliminates CW semi break in. <br>
<br>
I needed to do this for an EME installation where I am switching
sequentially several radios, TWT amplifier, two LNAs, two
waveguide switches, etc. Of course I have tried to make
everything "failsafe" with the sequencing but still it is much
better to avoid inadvertent brief activations of the transmit mode
when the CW key is accidentally bumped when the system is not in
transmit mode.<br>
<br>
The modified code works here as intended with no apparent
problems. However, I am not a coding expert, so there may be
problems with the code modifications that I made of which I am
unaware. Also, there likely are better ways of doing this. But
since no answers / help appeared here for Bill in the 3 years
since the question was asked, and since I needed the same
solution, I did what I could and this is a solution that works
for me here. <br>
<br>
I just made very simple modifications to the PowerSDR console.cs
file and to the Hermes firmware file. I also made a trivial
modification to titlebar.cs file so that I could tell at a glance
whether or not I was running the modified PowerSDR software. I
use my installation only with Hermes for CW and Digital EME so I
can't comment on suitability for other use conditions.<br>
