Hello Wolf!
All is OK, I just downloaded new version of SpecLab and I am going to
try it. THANKS YOU VERY MUCH!
I will give you some informations about my experiments.
73 and GN!
Lubos, OK2BVG

Hello Lubomir,
The SDR-IQ (and SDR-14) support is implemented since V2.7 b19, which is
available on my website (even though it's still under "heavy
development", since I soon need those functions in a radio astronomy
project - but that's another story). So I upload it quite frequently
without changing the version number. The latest version is here:
http://dl4yhf.ssl7.com/spectra1.html
The only "external" software defined radios which do *not* require a
soundcard for reception are SDR-IQ and SDR-14 (by RFSPACE), it has
nothing to do with SDradio. The reason for the direct support of SDR-IQ
was that I needed to **eliminate** the soundcard as "input source" for
the radio astronomy application, because of the heavy "baseband QRM" at
the telescope's site which affects the soundcard, but not the SDR-IQ
because it digitizes the RF signal directly (with an A/D converter
running at 66.6 MSamples/second) before the downconversion.
Best regards,
Wolf .
