This problem I describe in Bug Report #1525 really got me in trouble.
I hope it is addressed soon

Carl,
Great suggestion regarding nibbling out the holes in the fan ingress. Huge
reduction in fan
noise.

Not sure what is going on but I have noticed this several times where the Rx
gain is hung at a higher AGC then by Xmit it comes back into line.
I can make it happen now by being on the band say 40 meters with S6 noise level
and switching to the dummy load it will drop to S3 then if I hit the tun
"And a narrow but sharp hump."
what frequency?, 3 band or 10?, approximately how much?

I did several things to abate the fan noise. By far, opening the intake by
cutting out the hole (mentioned before) reduced the back pressure and make the
biggest improvement.
I also installed a thermostatically controlled fan controlled where the temp

I installed the circuit for reduction of electrical noise on the SDR 1K fan
as described here last July by K0VM. Having 20 ohms of resistance in series
with the fan reduced the fan voltage from 13.8 to 12 volts. It seems to run
quieter at this reduced voltage.

Hello Ian,

Ian, check your MIC level-you may have to increase your mixer or MIC levels.
You should achieve between -5 and 0dB on the MIC meter, regardless of Drive
level. For additional punch try using the CPDR. The latest SVN software has
an exceptionally good feature the "DX" control which will increase you
I suspect McAfee may be a contributor as well. I improved the
performance of my system by disabling the wireless network which
stopped McAfee's wireless monitoring and this one move seems to have
made a significant difference here.

Please can anyone else confirm whether they are having audio punch problems
on SSB, the problem seems to have occurred since the SVN upgrade on or

Note that this issue has been addressed in the latest SVN. 4096 RX DSP

Has anyone found a cure for the motorboating that is heard in the digital
output stream coming from the fdmdrv interface to the sdr1000?
I have tried everything from buffer sizes to reconfiguring the vac cables.
A clue might be that when the interface is first brought up in rx mode, there

The issue is that we use an audio tone to key the keyer. This tone has some
frequency offset. We do some trickery in the console to ensure that no
matter what mode you're in (CWL or CWU), the tone is transmitted on the VFO
frequency. This means tuning the actual transmitter away by the CW pitch
I have noticed this too. When you tune the flex to 7.000.6 in CWU it
is actually transmitting on 7.000.0. Go any lower and although you
may still show above 7.000 you will be out of band, and the flex
won't transmit.
I compared this to my 950sdx. When I tune it to 7.000.0 I am actually

I am using the new delta 44 driver under vista. It works fine for
audio, but I don't have an sdr1000 to test with. The new control
panel is nice. The only issue so far is that it causes the vista
sleep function to hang.

Welll there is one more issue with cwu and cwl
160 and 80 meters require cwl to get close to the band edge.
You will not be allowed to transmit if your in the wrong side of the
fundamental.
As that could put you below the band edge.
Try it. Watch for a Cluster spot at the low end of 160 and 80 me

CW modes only affect the way you receive.
In CWU (upper sideband, normal cw) higher frequency signals are heard
at a higher pitch. As you tune UP-frequency, the received signal goes
down in pitch.
In CWL (lower sideband, also called CWr or reverse) higher frequency
signals are heard at a lower

The "band plan" is in the BandText table. It does not designate whether or not
the mode is CWu or CWl, just CW. That is an operators choice (aka FLEXibility)
to decide what mode to use.
How you set a particular mode on a per band basis (and the initial default
settings) are saved in the Band
I can't find the portion of the band designations that would denote that the
cw portions 160 80 and 40 meters would/should be in CWL mode.
I'm sure it's in the .mdb but I'm missing it.
pse and tu.
