Memories for FM Broadcast switch to Narrow FM

[N8CVW]

SDRC v3.1 3AUG2021
WIN10

Greetings

Bug(s) :

1) 'Memories' entries set to BC-FM revert to Narrow FM after ~1 seconds after selection, a 2nd click sticks to BC-FM
2) filter width on display not reflecting BC-FM selection
3) BC-FM entry on Main Screen 'Mode' dialogue shows "175kHz Max BW", inconsistent with (faulty) single filter indicator line appearing at +112kHz when BC-FM is invoked via Memories entry

A) When using 'Memories' feature to store Broadcast FM stations :

- Mode : BC-FM
- Filter : None

B) Select (click) a Memory button for a (configured) BC-FM station

C) SDRC selects the channel initially set to BC-FM, station plays normally for about 1 sec

D) after ~1 sec Mode switches to NFM (with NFM modulation)

E) a second click on the same Memories channel then causes Mode to switch to BC-FM, which stays and plays/sounds normally

F) Exception : a single 'filter indicator line' appears at +112.5 kHz above set frequency when Mode is selected to BC-FM
- if 'Filter' is set to 225000, "Filter' stores as "-112500 to +112500", only single line at +112.5 kHz above set frequency still appears

G) Exception : Main Screen Filter 'Select Mode' BC-FM dialogue entry reflects '175kHz Max BW', which is not consistent with the filter line displayed (at +112kHz)

H) when Main Screen 'Filter' is selected to 225kHz then the Pan display correctly displays the 225kHz filter

Thanks for all Support,

it so happens that BC-FM falls over into NFM when just changing frequencies by clicking signals on the spectrum display

What SDR hardware are you using Paul?

Is it only a External Radio? in that case have a look at Program Options - Controllers - CAT - Mode Mapping

If that doesn't help then tell us what happens when you make a Favourite iso a Memory entry.

Or pls send us a full printscreen of SDR-Console incl the mode mapping pane. (use the camera icon provided in SDRC)
