It was a great pleasure visiting with you for the short time I could
stay. I had AMSAT duties in the afternoon at the Timonium hamfest and
though I have seen Mark's talk before, it is always a pleasure to see
his great work again and I apologize to the other speakers I missed.
The morning talks before mine were excellent indeed. I came home and
order solar panels and other goodies!
I really enjoyed giving the SDR SoftRock talk. Tony Parks, KB9YIG said
that he has received many favorable comments and orders for his Softrock
hardware and kits and I appreciate everyone holding Tony blameless for
my humble presentation of his great work.
I wish to extend my remarks at the presentation by giving Tony's email
in the header to this short note. Let me give links to lots of software:
The Rocky software done by one of my personal favorite amateur radio
software authors may be downloaded here:
The PowerSDR may be downloaded here:
The only version worth downloading at this time is the Beta software. We
are probably going to release version 1.6.0 this week.
The KGK done by M0KGK may be download here:
SDRadio is found here:
and Linrad is found here:
In addition I would like to post a correction to remarks made during my
talk by my old friend.
The PowerSDR is intended for a more complicated piece of machinery than
the Softrock and it does require the download of .NET and directX if you
do not already have it (most of your will) but it does not have a larger
CPU hit at this QTH than some of the other offerings. When the power
spectrum, panadapter update rate are set DOWN from our defaults to the
same rate as the other pieces of software, on this machine, the CPU
percentage is IDENTICAL to those people were claiming were more
lightweight or better suited. In fact, I see fewer audio break ups than
are seen with the offerings people were claiming were easier on the
computer and I have high end sound cards with built in DMA support and
well written drivers. In the past six months a lot of work has gone
into internal overhaul and optimization of the PowerSDR software. Give
it another look.
I want to thank Tony for his tremendous support of Atlanticon and the
donation of numerous pieces of hardware as door prizes.
