Re: [IRCA] SDR-Console and the Perseus SDR Volume Levels



I think my knowledge gap is showing. I'm sure that it meant to set the recording to 950 KHz and record the 1.6 MHz bandwidth stretching from 150 KHz to 1750 KHz. I'll give it a try tonight using the native Perseus software, then experiment with the add-on recording software options, and playback on other software platforms.

Thanks for the advice.

I'll bet some things are mixed up here. There's no sampling rate of 950 regardless of the unit you meant (samples, kilosamples, etc).
Did you mean to set the center frequency to 950 kHz? That's a common choice to record 1.6 MHZ (not 1.75 MHZ) of spectrum, thereby covering 150 kHz to 1750 kHz.
Whatever sampling rate and center frequency you use has really no effect at all on "quality", although I am not sure what that means to you. Chuck

Don,

I was advised that if you lowered the sampling rate to 950, the Perseus
could record 1750 KHz worth of bandwidth (the entire AM band). Have you
tried that? I assume quality might suffer a bit, but that might be
offset by the ability to record the entire band.

There is a volume tab in the SDR Console next to the speaker icon in the
VFO pane. Even tho it says 75 the actual level may be anything - it is just
an icon.

Using the native Perseus software recording is 1600 khz maximum - it
records what you have the screen width set to.

Got the new Perseus SDR hooked up and running last night using SDRV4.1
downloaded from the Perseus web site. No problems at all with the initial
installation on Windows 7 Pro. Had it working within moments.

One issue I did notice was that when I used the Perseus with the
SDR-Console software, the AF output volume was much lower compared to the
native Perseus software. No idea why this would be, and couldn't find a
place to adjust the level inside the SDR-Console software. Can someone
offer assistance?

RF levels appeared to be the same for both software.

So far, I love the Perseus! One other question--how much bandwidth can the
Perseus record in I/O mode? I've seen some sites that say it's limited to
800 KHz, others say 1600 KHz, and others 2 MHz. My understanding is that it
would cover the entire AM band, which would be 1710 KHz (1.7 MHz)
