Im trying to figure out what I need to do to
configure CWGet/SDR1000/Delta 44 card. The Delta 44/ SDR 1000 set up I
have seems to be working fine for transmit and receive and others can read my
transmission fine. The audio Im receiving is great.

Greetings Christoph,
I also experienced the problem you have described when I obtained my
SDR-ATU and installed it in the SDR-1000 in May 2005. My version of the
ATU did not contain the red and green LED's which indicate the status of
the ATU. After several exchanges with Gerald Youngblood,

nailed this one on the head. The
jumping around is because when spur reduction is turned on, the radio hardware is
only tuned every ~3.051kHz. We do
the fine tuning using a software oscillator. Also worthy of note is that we

the info for how to get to it privately.

Can someone give me the instructions on how to sign into TeamSpeak?
The link on the Flex Radio site is down, and I need to rebuild my computer
connection.
Thanks

I purchased a SDR-1000 used from N1JM and I need
access to schematics and what ever info is associated
with the radio.
Looking forward to my SDR experience.

The radio will work with the spur reduction on or off. Basically, you
can lighten the load on your parallel port and reduce the number of
spurs seen by leaving Spur Reduction at it's default ON position.
However, if you have an offending spur in the passband, you may want to
try to turn it off

I would be suspicious of the output voltage from the line-out from your

determining the line-out voltage, thus with the M-Audio Delta 44 sound

Interestingly, tuning across the band with spur-reduction Off does introduce
audible artifacts that are not present when tuning with spur-reduction On.
For example, if I'm tuning in 10 Hz steps with spur-reduction OFF, I hear a
distintive tick each time the frequency changes, and the receiver's

I am seeing something strange with my SDR. I
notice nowwhen I hit the MOX button in USB or LSB modes I am seeing full
output WITHOUT talking. I have done a number of alignments on two diferent
computers both using the sameFirebox.
what I have now are:

This is actually related to the asynchronous manner in which the hardware is
controlled with respect to the audio. When Spur Reduction is off, the
hardware is having to tune a lot more often and it can happen in the middle

wonder if two sets of buffers need to be sent back - one to be sent to the

This is approximately what happens under Linux. Generating sidetone

ports. (The keyer is
