Hi,
I enjoyed your comments on the g313i. I've experienced it's predecessor, the
g303i, at DXpeditions on the WA State coast. The g303i's real-time spectrum
display was extremely adept at revealing weak AM carriers on the mediumwave
band, that invariably turned out to be audio from trans-Pacific mediumwave
stations. It was a lot of fun to spot the "blips" between the domestic
10-kHz channels and tune into them, resulting in audio almost every time. It
became easier to spot the "hets" of TP MW DX on the g303i than to tune
across the band on our other receivers (listening to the changing pitch of
the carriers).
The Winradio compared extremely favorably against the Collins, WJ's, Racals,
RX340s, and modded consumer-grade radios in use at our DXpeditions. The
recovered audio of the g303i was just as good as with the other DSP-based
rigs (Collins HF-2050, RX340, etc.) The low noise floor of the g303i was
appreciated at our quiet location with Beverage antennas in use.
I'm sure your g313i exceeds the g303i in a number of performance areas, as I
see that some of its specs are better. If you can get away to a quiet
location with your Winradio, you'll really be able to "stomp the
accelerator" and see what it'll do.

I've had my 313i for approx 3 weeks now & I thought I'd post some
thought's
about this hf radio.
Do to the very poor wx conditions here in the Wash DC area USA,alot of
electrical storms,I have not been able to run the 313i,or any radio for
that matter,enough to give a better review of its workings.
First of all WinRadio has done a decent job re shielding.I'm getting no
more/less *noise* from the p/c than I get from my stand-alone hf radios,a
JRC 535d & a AOR 3030.I have a CRT monitor & I get the usual noise
depending on the tuned freq.Probably time to get a LCD type monitor.
This hf radio is by far the most sensitive radio I have ever
owned.However,for some odd reason,WinRadio has chosen to give the operator
only one attenuation setting.A on/off setting of 18dB.The 313i also has
what's described as "true IF" as opposed to a RF control.This is taking
some getting used to as the 313i does not allow the IF control to be on
when the AGC is on.I like having both available for use as there are
time's,ie fast fades, when having both AGC AND IF control come's in
handy.Also having both would help when the 313i's strong sensitivity is
too
much.
Another option that I hope is added in future software upgrades is
allowing the operator to point & click to a frequency while viewing the
spectrum analyzer.This is standard in just about any software type radio
I've ever used & is sorely missed.
However,over-all,this radio is a definate keeper.Their are alot of
excellent *pros* to this radio.The variable b/w control is GREAT &,when
viewed with the excellent spectrum analyzer,one has minute control.There
are also several fine-tuning controls which is invaluable re utility
trans.The 313i has 1hz tuning,a RIT & a RF-Shift control.The NOTCH filter
works to perfection &,as with most controls,has many different setups.
The 313i is not an easy radio to operate.Sure you can turn it on & begin
to receive lf,mw & hf trans immediately.But for dx'ing the weak
signals,dealing with QRM,ect the owner will need time to bring out all the
radio's tools & to learn how to best operate the radio in general.I would
not reccommend the 313i as a "first" radio
Eventually the wx here just HAS to get better.
Once I get more op-time I'll post more of my pro's & con's re the 313i.
