I've had my 313i for approx 3 weeks now & I thought I'd post some
thought's
about this hf radio.

Nice post Al, thanks for the information. Is it possible to use other
software on the pc while using WinRadio? Specifically, can you use
programs like Spectran for signal analysis and still expect a
reasonable time slot for Spectran or does WinRadio pretty much take up
all cpu time? Thanks for any info.

I have not run into any situation where a pgm. cannot be run if the 313i
is active.Once I tried loading Analyzer2000 while the 313i was running &
got a "sound card not available" error msg.However I have not been able to
duplicate this so I can't say it's a problem.Looking at a utility I
have,AnalogX's NetStat Live,the 313i does not appear to hog alot of CPU
cycles but I'm far from an expert re these type questions.When the 313i's
software is highlighted the CPU numbers seem to be right around 25%.But I
also have other pgm's running in the background,ie Eudora & this
pgm,Xnews.I've not noticed anything being sluggish with the radio on but if
this CPU question is an important question I can do further testing.

Talking about that *sound* subject just reminded me that I forgot to
include an important fact re the 313i.
The 313i,unlike most (all?) DSP/computer radio combo's,does not require
you to route the sound into one's p/c sound-card.It does its own sound via
its onboard DSP so one can plug a amplified speaker(s) directly to the
313i's audio-out jack.I say "important" not because this sound option
exists but because the sound quality is better via a direct feed.
Not having to go through the p/c's sound-card,at least in my case,has a
definate improvment in cutting down on whatever noise is added using the
sound-card for amplification.This is a fact even if the sound-card's
properties are manipulated via its controls.The computer that I have
installed the 313i in has on-board sound.Fwiw,a check of my system's info
say's the sound is a "Creative SoundBlaster PCI128".

It really does make a difference,especially on weak signals.The spectrum
analyzer on the 313i really does a good job in letting the user see trans
he or she might normally miss. As Mr.Atkins noted,re the 303 model,in his
post,the spectrum analyzer allows the user to tune in a signal & get audio
where other-wise this might not be the case.Of course the 313i *see's*
everything via the spectrum analyzer including noise.interference,ect.But
once the user become's familiar with the spectrum analyzer's looks they can
recognize what they are looking for.

One other thing come's to mind & it has to do with recording.The 313i
software has a built in real-time recorder where any trans can be saved to
a wav file.However,& this is really neat,instead of recording to a wav
format the trans can be recorded at the IF.This allows any play back to be
treated as a "live" trans & subject to any manipulation via the 313i's
tools.This option can be vital re digital ute trans.

As I said,this radio has alot of different uses,setups & formats that need
to be gone over in detail to realize its full potential.
