I just completed a thorough format and reload of my PC, a Gateway Intel Core 2
Duo with 2G of RAM. Everything was working perfectly until I received a .pdf
file from my local ARES organization. As soon as I loaded the current version
of Adobe Reader the problems started.
Adobe would not let me
One of the things that I wanted to accomplish with an SDR receiver,
is the ability to keep an eye on the whole 14065 to 14115 frequency
range. If I was down on 14074 monitoring ALE 400 traffic, I would
miss Olivia signals that popped up in the 14109 area. I would also
miss Hell signals at
I want to start up a packet system: What cables and software do I need to use
my VX5 as a packet engine using Outpost software? I want to use my Gateway
LT2022u XP netbook's soundcard and USB connections. No serial connections and
no external TNC please.
So far the best I've found is the:
Andy,
I plan on switching to SDR in the near future. My current PC
is a dual CPU 2.2GHz Dell with 3 GHz RAM. Any idea what the
minimum PC requirement is to run Multipsk with SDR? Could
you also tell us what processor you're running now?
Thanks,

Tony, my shack PC sounds like yours. A Dell P4, 2.3 CPU , but only 1 gig of
RAM. Perhaps we can compare current system resource utilization for regular
Multipsk ?
Regular Multipsk in PSK31 mode with a 4,3 Khz waterfall uses 25 % of CPU.
With RS ID on , about the same 25-26%
With Panoramic

Adobe has a long history of buffer overrun bugs leading to exploits.
There are third-party readers for PDF documents that are safer. Since

Hello Tony,
I have here two PC XP at about 2.4 GHz (single core):
I have compare these two XP computers on the same file to decode (in 110A):
* the first one (the oldest) which is an AMD Atlon 2500+ 1.09 GHz 768 Ko RAM
takes 75 seconds to decode it,
* the second one which is an AMD Atlon 2400+
I understand sound cards. For digital modes, we need to know how to
set up audio coming in to the soud card and out of the sound card.
When there is more than one sound card in the PC, we need to know how
to set up digital mode applications for the desired sound card. All
relatively easy (except
Here's an example of what you can (and I did) do with VAC:
I remoted my station audio from the PC that is connected to my Signalink to my
laptop that I carry around the house using IPSound. IPSound wants to attach to
a sound card for input and output, just like DM780 (or Fldigi, etc.). Indeed,
I have a mfj 1275 with an 8pin output, does anybody know what i would have to
do to change it to 4 pin output for a kenwood ts-830S... i would like to build
an adaptor or change the cable end to 4 pin
Thanks Kb0swo
Andy,
I configured Multipsk as you described and the CPU usage
seems to average about 5 percent. Panoramic mode is about
the same. I've included a few screen shots so you could see
the results.
Mixw seems to tax the CPU the same way as Multipsk does, but
Fldigi needs a bit more to run - CPU
Patrick,
Thanks for the information. As you may have read from my
reply to Andy, my CPU usage seems to be very low with
Multipsk. It's well below 10%.
Is there a particular Multipsk mode or configuration that
would tax the system? I'd like to try it and see how it
affects CPU usage.
Merci
