<DIV>G’day </DIV>
<DIV> </DIV>
<DIV>It has been interesting to follow the discussion in regard to the
development of software for the various pieces of hardware produced through
HPSDR and the commercial extension of this by Apache Labs.</DIV>
<DIV> </DIV>
<DIV>As a scientific journalist and ‘Igor’ to my great friend Phil Harman
VK6APH/VK6PH’s ‘Dr Frankenstein’ in his explanation of basic SDR principles in
the RSGB’s RadCom magazine and their extension into HPSDR development, there are
a couple of basic ideas/principles that Phil works by which I think recounting
here would be timely.</DIV>
<DIV> </DIV>
<DIV><EM>1. The development of open PowerSDR and the associated
software/hardware is a hobby for all of us principally concerned in
it</EM></DIV>
<DIV> </DIV>
<DIV>CuSDR is a fantastic piece of software development. Part of this is it has
a wonderful GUI, but it is a fully integrated piece of software that Hermann
DL3HVH kindly developed in his spare time until he developed a very debilitating
and life-changing medical condition that meant he could no longer continue its
development. </DIV>
<DIV> </DIV>
<DIV>People should accept the development of CuSDR has stopped. It seems to me
the only way this situation could possibly change is if a suitably skilled
programmer is prepared to step forward and approach Hermann to see if he would
consider handing over a copy of his code for future open source
development.</DIV>
<DIV> </DIV>
<DIV>I hope I’m wrong, but don’t see anyone rushing forward to offer Hermann
their services.</DIV>
<DIV> </DIV>
<DIV><EM>2. If no-one volunteers to carry out a particular part of a development
and then sees it through, it ain’t going to happen </EM></DIV>
<DIV><EM></EM> </DIV>
<DIV>The development of Open PowerSDR has been done by a a small group of very
dedicated enthusiasts who give their time freely (literally) – take a bow Bill
Tracey, KD5TFD, Doug Wigley, W5WC and Dr Warren Pratt, NR0V. Similarly, the
hardware development has kindly done by a similar small group of very dedicated
volunteers, of which Kjell LA2NI is one.</DIV>
<DIV> </DIV>
<DIV>The software works well but everyone is a volunteer, with their own
interests and abilities, which means that software development doesn’t
necessarily proceed in a logical or straightforward manner. If there had
been someone who had volunteered to re-do the GUI side and had the knowledge,
ability and time to complete this, it would have happened! No volunteer who
could do this means no change in the GUI. </DIV>
<DIV> </DIV>
<DIV align=left>On a final note, for me, there is one thing that has - and will
always - limit the development of software defined amateur radio – there are
simply not enough people who are interested in writing software for it, have the
necessary skills do it and are prepared to volunteer their services to do
it.</DIV>
<DIV align=left> </DIV>
<DIV align=left>However, thankfully there are a few who are – but we shouldn’t
expect miracles from them, or that they devotedly do exactly what we want them
to do. </DIV>
