Setting Bandwidth Automatically ~ W/N

Hi, I started a thread/post on FB with Gary, NC3Z,, But I think it maybe better here.?

Using FT-991A Currently run FT8 quite frequently, Bandwidth is set to 3200 Hz (per JT's "Wide as possible") When I Start VARAC the Bandwidth is still at 3200 HZ, I do see the "Red Tramlines" spaced 500 Hz

Gary sent some details and references about CAT commands

That could possibly be set in the config file when VARAC starts to set Bandwidth to 500 Hz

and then return to 3200 Hz on exiting VARACt.?? I download the FT-991A CAT Manual, looked at the commands Gary mentioned,

NA = NARROW on Pg: 13 and SH = WIDTH on Pg: 16 I'm not sure what and where to start, basically understand concept, clueless on the "How To.?"

Any guidance would be very welcome...

Cheers... Dave

Hi Folks, I'm back... Just a bad period of chronic fatigue, on a plus side,

I didn't have that much hair to loose because of Chemo... O.K, I want to try this alternate method of CAT, instead of OMNIRIG. First Challenge/Question... When I currently start VARAC, It automatically starts OMNIRIG If I now want to use CAT, Do I need to "kill" the OMNIRIG process 1st Then go into setting and reconfigure..?? Thanks... Dave

Replying to

Dont do the 500hz filter. If someone is a bit off set you will not be able to decode.

Best practice is not to use filters at all (like with FT8). No real meanin of the filter. VARA will only decode whats between the 2 red lines.

Same goes for narrow. Stick to USB-D.
