software all that is need is to look at Sigmira software phase
display method and if possible provide 0.1Hz resolution instead of 1Hz.

Chris,
just a suggestion. Tune to WWV with Winrad, and set it to ECSS mode. This
will activate
the round phase display below the S-meter. And the corrections to the
frequency caused
by the ECSS algorithm have a granularity well below 1 Hz, even though the
display
use my old XP system
(2 Ghz Celeron)?

I do not understand the purpose of a phase indicator.
It would be hard for me to explain properly with my limited

Hi Leif;
I read your e-mail to ask if there is a software transceiver out there. And
yes there is...it is called MDSR (Modulation Demodulation Software radio).
It uses the optional filter

I am aware of the Flex radios. Also the fact that their TX modulation still
happens inside the radio box. Also the price for the radio is extremely steep.

- see their FAQ section for details.
And sorry, I am not a programmer myself unless you count efforts years ago with
hand assembly and early 8 bit uP's like 8080, 6502 etc!

Maybe your software could go a stage further i.e. measure the audio bandwidth
and guess where the carrier should be?

After I have played a WAV file and I go to start my SDR-IQ there is no start

both channels about 45° and the result
is the same.
In my HDR-2005 I use an active filter with 4 Dual-OPs (look at
soft_radio/Files/HDR-2005). If You want, I send You a detailed
schematic. My troubles with demodulation are not SSB (it sounds very

hello everyone one - Please pardon this cross

major interest is in the HPSDR suite of hardware software but I also
have an Elektor board. Is the code available for download? What
licence is it covered by?

As far as I know the SoftRock RXTX V6.x kit takes I Q output from a
sound card and produces RF in one of a number of amateur bands. So if
you can generate the ISB signals in software then the SoftRock
hardware will produce the signal.

protestation to the
contrary, it probably out performs most commercially available amateur
equipment. viz the digital filters have vertical sides and are near infinitely
variable in width etc.. Don't ask me to quote specs because I can't. Do the

frequency measurement and allows DSB/USB/LSB when needed.
And finally a good notch filter would be nice - manual ones seem the
best. Ideally one that can be set to auto or tuned manually.
