Here Here. Why in the heck not! I have posted several times an SDR dedicated
board/link between the radio and the computer, others have already posted
the connections to the DB 15. We can take a connector to the db 15 and do
whatever we want! Filter, preamp, isolation FO or otherwise. T

I had a report that the recordings that I made last

others that have been made. How does one control the
level of the recording? is there a Console setting that

Yes, the IC-7800 introduced toslink to the ham hobby
and it seems to work wonders on digi modes. One hopes
that similar optical (read: NO RFI EVER) links will see
their way into the hobby over time. Maybe some vendors
will offer toslink adapters for USB and audio lines?

Since receiving the SDR-1000 in July 2003 I am fighting the RFI, spurious,
noise and common mode issues and no final and universal solution yet! So far
I try to manage with isolating transformers in I/Q lines (input and output),

Do the following. Fix the console so that you have the soft clicking
going on.
The change the spectrum display mode from spectrum or panadapter, etc.
to OFF. Tell me if the click goes away. It does here on the development

Hi Bob,
Yes, I have been fighting the BAD_POOL_HEADER problem since I got back
from vacation. It seems to be a timing problem because when I have
windbg running I can not get it to crash (since it slows down the
system). It passes verifier and prefast testing also. I have tried
debugging it wit
Alan,
I like your idea very much. I would like to try it out on psk and the
other modes. I see a lot of application for this.

Ken,
Based on your response, I checked out my USB devices. They are the SDR USB
to parallel adapter, the Griffin PowerMate and a mouse. I subsequently
removed first the PowerMate and then the mouse (!), while PowerSDR was
running, but to no avail, so I'm still open to ideas.
Thanks anyway,
Joe

Phil,
I loaded build 72 over the long weekend. It worked fine with MixW but I got
a BSOD (BAD_POOL_HEADER) more than 50% of the time when I tried to start
DXLab Commander (which was not responding when I didn't get a BSOD).
Running Beta 1.3.5 on a Dell Dimension 8400 and XP Pro.

I have designed a bandwidth control system for the SDR. I believe most
operators will find this approach to bandwidth control, familiar because
these methods have been used on Kenwood and Yaesu radios for years.
It takes up little console real estate with its two sliders & indicators and
Joe I experienced something similar when I had USB speakers and a
USB WiFi link at home. Unplugging both devices eliminated the
clicking. I took it to be some sort of polling on the USB ports
somewhere within my poorly shielded PC.

Hi
All,
On SSB receive, I am experiencing
soft clicking sounds when both the
NR and ANF are on. I have played with many combinations of DSP settings and
audio sample sizes, but nothing seems to help, nor does cycling power
on/standby. CPU usage is around 10%. Does anyone have any ideas?
Some thoughts:
The voltage drop associated with the 1:4 mux could easily be offset by using a 1:4 W2DU current balun. 1:16 would be another option, but probably not necessary.
The balun would work well on a board with a "balanced Tayloe" mixer as per the Tayloe article.

Jeff,
Double check your output connections. Make sure outputs 1 & 2 go to the
speaker (not the radio). And Outputs 3 & 4 go to the radio plug marked
To Line Out.
