Hello Rockers

Built a SoftRock40 and tried the more common SW packs available for Win.
Running winxp home on a 1.4 Centrino laptop with a SB audigy 2 NX (usb)

With PowerSdr had to use 2048 blocks and 45 ms latency to get it to
work without hiccups. (all other features are very nice).

With Alberto I2PHD SDRadio again had to use 2048 blocks and 48khz
(liked better the way BandWidth is controlled) at 96 khz sampling it
begins to sound rough and hiccupy.

Then came Phil Covington's SharpDsp MiniConsole (which still lacks a
panadapter display and some other niceties) and here I can set a 4096
blocks value (some more latency, true) and Lo and Behold! works really
nicely with 96 khz sampling rate.

Now I get more than 90 khz of the band (which in region 1 is almost all
the band!!). Amazingly the sensitivity is uniform all the way (heard a
rumor that even at 96 khz there is a AntiAliasing analog filter on the
Audigy input...proven wrong!)

Tried the new Rocky by Alex VE3NEA and regrettably it does not work
with my Audigy (gives a 'unable to start input from SoundBlaster Audigy
2 NX) so cannot test operation at 96 khz. Well I'll wait and see if
more people have the same problem...


Will try to operate on external supply and see if the noise at the LO
is power supplied by the USB or a ground loop (or both).

Hav'nt seen the I/Q automatic balancing work yet but in the other SW
packs it is really something to be addressed because the image once
nulled on a certain frequency is definitly growing and changing on
other freq. So a mapping (table and interpolation) or the automatic
way shoult be implemented IMHO.

Have a nice (Rocky??) weekend de Joe

Rocky also won't start the Audigy 2 NX external USB card here
either. Won't work with 48 or 96 Khz sampling, or if you set a
second card as output. I get the same error message as Joseph. But
looks great, I'll have to boot my wife off the tower system to try
it with the internal card there.

I had the same problem with the "Rocky" software, and after I installed ASIO4ALL and made it the audio driver, the error then went away. I was using a different sound card, a SB Live 24. You can try it by downloading it from the link below;

I really like the "Rocky" software, it's more adjustable on what you see on the Panoramic display, and very easy to find stations. I also really like the waterfall display, it looks really good. Two misuses, the dB scale is backwards from the way I'm used to seeing it, and the receiving window is not centered on the Panoramic window, so I can't see what is below the frequency I'm listening to. It's a really simple to use software, if you haven't tried it you need to.

Overall we have available a good selection of software to play with, not bad considering the SR-40 was released not that long ago.

Thanks to all the developers.

I fail to see why doing the same thing over and over and getting the same results every time is insanity: I've almost proved it isn't; only a few more tests now and I'm sure results will differ this time ...

Hello all

Tried Asio4all didn't work for me (still the same error "unable to
start input from usb soundblaster Audigy 2 NX"...).
Anyway as I am intersted in SSB as well, ROCKY has (for the time
being?) only 600 hz max BW. (It's true it has some very intrigueing
promises in auto image elimination and more...)

By the way I use my Audigy USB as the input and use the laptop Conexant
native sound card as output to the speakers but that enables any
digital modes software that can select input source from the conexant
to work fine (including winDRM)on the audio coming from the SR40.

Hi Cecil,

the
receiving window is not centered on the Panoramic window, so I can't
see what is below the frequency I'm listening to.

You can move the operating frequency to the center of the display by dragging the frequency scale (the gray bar under the spectrum).

Try this also;

Go in the control panel and run the "Sound and Audio Devices"

Make sure all the voice and music devices are the sound card you want.
