I just set up the firebox and these are some issues
that have come up. (receive only) Probably too many
topics at once for a forum... any suggestions appreciated.
1. there was no 6-pin to 4-pin firewire cable included
for my laptop -- had to go out and buy one.
2. I tested the firebox with
I ran the fftw_wisdom program and all my PowerSDR sound and dsp buffer
options seem to work now. I'm not sure what happened or if fftw_wisdom
fixed it.
I changed my audio output device from directx to the presonus and the
dropout problem might be reduced now. Needs more testing.
I don't know if this is only in Beta 19, but on the Setup/Audio/Sound
Card tab, the Output Voltage defaults to 2.23, whereas I measured 0.7 on
my MP3+. The program tells me this is way outside the statistics for
this audio device, but 0.7 makes SDR-1000 transmitter work.

I calibrated my receiver this morning using Preview 19. Using an XG-1
calibrator, I get a calibrated level of -71.5 dBm for 50 uV input. I went
back to Preview 18 and it calibrated at -73 dBm for the same input. Wonder
if anyone else has noticed this?

Well gang,
This morning I downloaded beta 19 again and now all compiles are back
to normal, both in Release and in Debug. I went through the same steps
yesterday and could not get the Debug to work and Release would not end up
starting the console after compiling. Anyway now we are
I was tuning around the 80 meter cw band tonight and heard a broadcast

I checked the frequency on my Kenwood TS-450 and could not hear the
broadcast station. I suspected that it was an inter modulation product

I don't understand this. You are putting some signal in the radio and
telling it that this signal level will henceforth be called -73dBm. It
should matter what level it is, you are arbitrarily calling it -73dBm
and to the extent that it really is - 73dBm, the meter and the noise

Was wondering if anyones performed comparisons between the Delta-44 and
the Presonus Firebox in regards to latency. I realize that with either
configuration there will be latency through the ASIO drivers, (asio4all
or the M-audio asio), however I'm concerned that some of the values I've
seen
Jimmy,
just read your comments re the Firebox on the Flex reflector. You'll
likely see my query on there as well. I was just wondering if your
current settings (sorry the formatting didn't work to well on your
configuration table) for the Firebox is 1.5 ms or 18 ms?
I can't see how this would work
Sorry everyone. Last post was meant for Jim direct. Lesson to the

Good idea, just don't try and reply to one ..duh! (it'll turn up on the

No problem, -73.3dBm and 107.8dBm.

Bob,
Looking good so far. A comment relevent to users outside the States. Although
those of us who have grown up with Flex-radio know this, some confusion can
arise for new users in trying to use a local bandplan. The current database
file is easily modified using Access, but if this modified
Do svedanya Sergei!
What we are thinking is that there may be other settings which can
interfere with calibration. If there are these settings (polyphase,
average meter, average spectrum, ???) we need to know what they are
so we can turn them off automatically when calibrating and later
Bob,
Just calibrated Preview 19 here using XG-1. Calibrated as expected (-73dBm)
with polyphase, avg meter and avg spectrum all on.

Thanks for the help. I also have stopped all unneeded background processes,
services.
I still can't get rid of the dropouts. The audio sounds great otherwise, and
there is no
problem using other apps like browsers at the same time. Just the occasional
dropout.

Yes Kirb
The latency setting on the Firebob is 1.5 ms.
I forget that I'm the only one using an SDR 1000 that doesnt use CW at all.
Hey, I like psk31...
Those numbers that I gave out have only been tested on ssb.
I forgot to mention too that I run the Process Prority in Realtime.

I also performed a new rcv calibration on preview 19 using a 10 Mhz -37
dBm signal source (a measured +3.0 dBm signal and a 40 dB pad).
The signal meter indicates the following values :
preamp off = -35.4 dBm
preamp low = -35.9 dBm
preamp med = -35.3 dBm
preamp high = -35.9 dBm

I did it several times on each version, in the same sequence, I think.
The preview 15 values still were 0.6 dB off.
I´ll repeat everything tomorrow (now almost 03 am here). Also I´ll turn
polyphase and other things off. What amazes to me is why I say -37
(been this the right value or not),
I use a CREATIVE 3P FIRE/3P USB to pci card that works without a problem.

Noted your msg was for Jimmy and not the list. I run my Firebox at
10 ms, and CW is fine. Let me qualify that, however. I use an
external electronic keyer.
