Sett Menu: SAM mode settings
Sett Menu: SAM mode settings
Could anyone explain (simply?) just how the SAM filters are intended to work please?
The bandwith control is self-explanatoy (I think).
However, just what the HP Filter FC is remains a mystery to me (and perhaps others).
I had initially assumed that HP perhaps stands for HIgh Pass, which but what of FC? (If so, why associate a high-pass filter exclusively with this mode?
There is pecious little guidance that is understandable to a neophyte in this part of the manual I'm afraid, as elsewhere in it, the authour/s probably assume a depth of knowledge greater than users not versed in radio-technology possess.

Hi Paul,
I use SAM regularly in SDRuno but must confess to never having seen the options FC and HP that you ask about. Where are you seeing them?

Hi Martin
Thanks for your response.
These are to be found on th receiver control panel, under the SETT menu as SAM/HP.
I had assumed that HP Filter probably referred to a High Pass filter, but if it is, I have certainly failed to to use it effectively.
As far as my use of SAM is concerned, it is normally my preferred operating mode (initially) for DSB/SSB, but occasionally, after software (Win 10) updates, it throws a "wobbly" and signals corrupt after seconds/minutes.
I am usually (eventually, after ignorant fiddling) able to stabilise it until the next update event.

High pass frequency cutoff.
Lower frequencies are suppressed in the audio playback. That is, you have more or less "bass" when e. g. listening to a music station. e. g. 50 Hz: for music, e. g. 300 Hz: for speech.
This setting also works for AM and LSB, USB, not only for SAM. SAM/HP does not mean that both are related.

Hi Paul,
Well after a year of using SDRuno, I had never strayed into the SAM/HP settings. It just goes to show, there's always something new to play with.

Thank you (yet again) Heinrich for your time and sharing your knowledge.
All is clear now, to be honest I had noted the tonal effects, but had assumed that it was a by-product of some other function.
I am wiser now (and happier too), there always seems to be something new to learn with uno.
