Jeff,
One possible cure to avoid said jiggling and twisting of the plugs is to
drill larger holes into the backplate of the SDR1000 enclosure. The
relatively small holes may prevent certain types of male plugs to reach the
bottom of the female connectors. Gold-plated plugs here in the old

Jeff,
That is exactly my thought. Have Jon do a two tone transmit at max power
from his QTH to yours and see what the spectrum looks like on your
panadapter. Have Jon keep the transmission to a few seconds.

Recently I built a couple of wide-band common-base transformer feedback
(CBTF) amplifiers as described by Dallas Lankford in this article :

Larry,
To the best of my knowledge, I cannot recall an offi-cial warning from
Flex.Radio against the use of gold-plated plugs. In contrary, these were
praised many times as problem solvers on the forum and reflector without
objections. Anyhow, they solved my problems and twisting is now done
Rather than enlarge the hole, I used a
knife to shave the plastic on the plug end.

Mike,
Good suggestion, but less useful for those who use gold-plated plugs in
solid brass.

Thanks for the great information, Cecilio. I have read this article before but
had not thought of using the design ith the SDR. From your description of the
benefits, these amps sound very useful for the weak foreign signals I DX on the
MW split frequencies.

A number of us SDR experimenters have been building such a thing. The
sound card part is called Janus and I believe it has quite good
performance. It's based on the AK5394a chip, and can be jumpered to not
have an attenuator on the inputs. More details on it at:
John es list,
I just installed the Edirol sound box and it works great! The audio sounds
cleaner than the Firebox and the wide panadapter is very cool.
I was not able to reliably run the Firebox at 96K sampling rate (CPU

Hi Dan,
The Janus board (hpsdr.org) has a jumper selectable 15dB attenuator fitted to
its input so the board can be used with an existing SDR1000. The attenuator
can be taken out of circuit and the input connected directly to the A/D
converter on the card for optimum SDR performance.
This
In the official 1.6.2 release where there is an option in the audio tab to
test the output voltage, what is the level being input to the Delta 44 if
chosen in the sound card selection?¿
On a second note...How much latitude does the PA gain by band settings
calibrate function have to adjust to
Can anyone offer any advise on making the recorder work.
I can play back to myself now but I can't play back a recording over the
air.

As a selectivity enthusiast, I must bring to everyone's attention that
SVN 692 is a major milestone in the human-to-machine interface for two key
selectivity functions. The keyboard shortcut for IF Shift is now
operational, along with the keyboard shortcuts for Filter
Width. Programming
The selectivity control of the SDR1K has be be one of the absolute
most impressive functions of this rig. I can't say how great it is
operating SSB or AM, there are no words ;)
Just when I thought that selectivity control could not get any better, it did!
Thanks!

Good long haul propagation on 80 meters tonight. The local (0 - 300
mile) stations were not copyable at all, however the east and west
coast were heard here Q5. Here is a recording I made from my QTH of
Bob/W2ZM in Penn Yan, NY (Upstate) while in QSO with him. There were
others, Bob/K0NT in
I see the URL I posted was not interpreted well in FireFox, so I shortened it:
