Selected Mode Changing By Itself ?

 

Hello,
?
No big deal, just falls into
the "annoying" category.
?
I have the radio menu set to AM
?
As I scan the frequencies <30 MHz, or so, the AM
selection changes to something else.
Usually USB, but not always.
?
How can I lock it to AM ?
Why does it do this ?
?

Funny thing about "bandplans". They could be yours, mine, the plans of a complete lunatic, but generally, those of some one, or some club, we've never heard of, are a part of, and never will be.

I this case, the plug-in is an utter failure. The fellow wants AM, can't have it, because of some clown with their own notion.

If done correctly the plugin will read a data file. If you don't like what is present but do like the idea behind it, edit that file and Bob's your uncle.

All things being equal, that makes for a potential of roughly 8 billion "bandplans", if each one is only used once.

Odd that any would be provided at all.

I agree. The first thing I do with a new version of SDR# is disable the irritating bandplan plug-in. I often use the "wrong" mode.

I find editing the bandplan.xml fixes most of my issues with mode switching preferences.?

I use the bandplan auto update feature a lot (though every once in a while, the mode doesn't switch when making large frequency excursions - like when hopping between FM broadcast band and amateur HF band).

Some band plans are very regionalized to your locale of the world though, so it helps to start out with a file regionalized for your part of the world. There are some sources for regionalized band plan files online. I downloaded one of them, and found it quite helpful, especially when navigating VHF and international shortwave bands.

I often end up editing the bandplan on the upper portion of the 40m band to default to LSB mode, where international AM broadcasters occupy the range of 7200-7300kHz. The US Amateur radio band has a shared allocation there. As a CW operator I also updated mine to include CW mode zones within the amateur HF bands. You just have to make sure there are no overlapping frequency ranges.

It's not too difficult to decipher and update the file if you learn a bit about the rules of the XML format. Unfortunately, I have to use XML every day for work. ??

There is an option in the SDRSharp config file to auto-save current mode setting in bandplan on shutdown that can mess up your bandplan file preferences, so I do disable that. It trips me up once in a while if I forget to restore that setting after installing a new version.

Once you get the file the way you want, just make backup copies and copy it between your SDRSharp install folders.

A non-enforcing bandplan is something I can live with, reluctantly. If it auto-switches to the bandplan mode I freak a little at the unexpected "just trying to be nice" change. That's me probably not thee. A tool that prevents me from going to CW in a digital sub-band gets ripped out by its roots and given the ceremonial 6 wraps of lead foil and wax before it is staked and buried at a fork in the road at midnight under a full Moon. It's not because I would even dream of using CW. That's a mode suitable for Renaissance Fairs. I like modern. But, I an not at all averse to running USB on 75 or 80 Meters. (Or LSB on 432 MHz just to be obtuse during a contest.)

{^_^}??? I admit to being somewhat weird. No. make that WEIRD. Its my damn mind and I gotta live with it.
