The way I had success was to run directly to the sound card and not through the
SDR1000 box. Got rid of a lot of hum and noise. I'm using a D104 with the
preamp in the base that is battery powered. It goes directly into the D44
sound card input through the Eric2 interface card. I also have

All,
I added two new CAT commands to Preview 10: ZZTH and ZZTL provide control
for the TX filter high and low settings. There is also a updated CAT

I'm experiencing what I assume is the I and Q buffers losing sync. Once
this happens quadrature is lost and a DSB and a delayed DSB audio signal
is transmitted instead of SSB. It has happened in all the previews and
has been causing problems with interference to other stations.
It seems to
Thanks, Bob. This turned out to be the problem. The SDR1000 self-calibrates
fine now.

I just tried Pre 10 on 40M. Tx SSB is 11 KHz below the Rx freq.

Hello All,
I'm new to this reflector and planning on getting a SDR-1000 soon.
My goal is to eventually use it for CW and RTTY contesting.
A couple of questions of which I can't find the answers.
1. In CW mode how is the side tone level set?
2. What are the paddle input pins when using a serial

John,
Thanks for the heads up on this (Also thanks to KM0T who saw the same
issue). This was an ordering problem that was introduced with the fix
for the X2 issue. I am posting a new version of Preview 10 that has the
problem corrected. Please uninstall preview 10 and download the one on

First of all, any osc multiplied up widens its sidebands
(phase noise) by the multiplication factor and the inverse is
also true. The DDS does a 20X to 200MHz and a divide by 20 to
get back to 10MHz. I guess it's academic at this point how
much jitter is added by the DDS until someone measures

Gentlemen,
The DDS does Direct Digital Synthesis hence the name. It does not
divide
back to anything but runs an phase accumulation engine at 200 MHz (or
whatever
the clock rate) that produces output values to the dac at that rate.
No division is performed.

The best way to do this is to go through
the Control Panel - Add/Remove Programs and remove Preview 10 there. That should allow you to reinstall the
corrected P10. This was a quick fix
and we will likely have a P11 out by the end of the week to clear up the mess.

Richard, that's a question I've been meaning to ask someone -- whether
there's any phase noise improvement resulting from the (apparent)
division of the clock signal by the DDS, or whether the output phase
noise is always the same as, or worse than (due to imperfection in the
DDS process), the

Before making that purchase I wanted to inquire to those who have been

Since I haven't seen any posts related to the FireBox and it not working

Phase noise when multiplied by 20? I understand from others is that is not
as bad as imagined.

Much of this probably has been written for the third time on the various

Rich,
It was a cockpit problem. I had the AGC set on fixed and the fixed
AGC gain set too low. Once I set the AGC to any other setting, I had
plenty of audio. It really was not related to the Firebox.

Thank you Lee. Voltage is 2.5 during receive and about 1 volt with RF on it
during transmit. I would say you hit the nail on the head in regards to IC2
being bad. Thanks for your help in tracing this down. Much
appreciated!
