Many thanks for this news – there is no information on your website yet.

I will update my Web site when the new build will ready for distribution.
Main changes are a bigger screen, 800 x 600 now. Argo V2, which I will
release in summer or autumn this year, will
have a dynamically adjustable waterfall size, in real time, even when the
waterfall is running. But this version,
V1 build 137, is fixed at 800 x 600.

In addition the sound card is selectable, and the problematic sampling rate
of 5512 Hz has been abandoned.
It gives problems with the recent sound cards, and even though Windows can
resample down to that rate,
the frequency accuracy suffers...

Another change is the optional use of a polyphase FFT, where some gain in
frequency resolution is achieved at the expenses
of time resolution.  Also the windowing is no more done with the Hamming
window, but with the Nuttall one.

The time display can be select among local and UTC, and an optional field
is present on the panel, where to put
name, call sign and locator, to identify who did the screen capture.

And some minor errors were corrected (and probably new ones have been
inserted, but this is unavoidable.... :-) :-)   )

A thing I contemplated adding is the timed FTP upload to an FTP server, but
I will do this in a subsequent release,
if there is enough interest for this function.
