HDR Mode Questions

#1

Unread post by Robert11 »

Hello,

Have a few basic questions re the HDR Mode with a RSPdx, please:

Asking, as I seem to be having contradictory results, and it's obvious that I really
don't have a firm understanding of using it, and/or making it active.

a. That you can start the program with any selection, and later on simply select <2MHz Low IF from the HONE/BANDWIDTH on the ribbon.
Is this correct ? (doesn't appear to be true ?). Or, you really have to initially start with the <2MX Low If selection ?

*and, if has to be actually started with, anything below <2MHz, or has to be the actual <2MHz option ?

b. And during usage, if not at < the 2MHz Low IF, you can go back to it on the Ribbon later,
and it will again be "active.
Correct ?

c. A few words of how to select and use all the filter options for this mode
would really be helpful.

What else should I be asking re it's usage ? Hints/caveats ?

Do you folks find it a very useful mode to use ? Why ?

Thanks, much appreciate the help, as always,
Bob

Your questions are valid for all SDRplay models.

a. That you can start the program with any selection, and later on simply select <2MHz Low IF from the HONE/BANDWIDTH on the ribbon.
Is this correct ? YES, correct. (doesn't appear to be true ?).
Or, you really have to initially start with the <2MHz Low IF selection ? NO

b. And during usage, if not at < the 2MHz Low IF, you can go back to it on the Ribbon later,
and it will again be "active. Correct ? Yes, it starts with the last used BW

c. A few words of how to select and use all the filter options for this mode would really be helpful.
The Filters that you can choose from are Mode dependend. There's not much info about filters on the website yet but have a look here: https://www.sdr-radio.com/filters. Or specify your question more please.

What else should I be asking re it's usage ? Hints/caveats ?
Stay whenever possible on <2MHz Low IF (less spurs, less cpu usage,...)


Do you folks find it a very useful mode to use ? Why ? HDR? i don't know, i have a RSP2
