Re: Filter Verification

Try -s//&/D  You have to say which alternate table symbol you want the overlay to apply to.

The easy way to test this is with the inverse of the symbol as just the filter in a FilterTest.  s///D doesn't get anything while s//&/D gets the D-Star stations you're trying to get rid of.

hmm... so, I updated my filter to

but I'm still getting hits on stations with the "D" overlay

Thanks Lynn,

so, if I want to filter out all of the -s///D symbols I have no way to send the D-Star Repeater with that symbol, I would need to recreate it as a repeater object and send it separately. 

Thank you, I thought I had it right, but it's been so long I wanted to double check with the more knowledgeable.

Yes, anything that says "hit" will go out.

And yes, the -s///D will trump (not allow) anything that was previously selected.

"-b/*-B" will not work because the * only works at the end of a station ID.  It is not a wildcard like used in a file system.

I know that this is an old topic but I am looking for verification that my filter is set up correctly for IS to RF
Can someone also confirm in the Filter Test (ctrl+G) that when it says "hit" that it would be transmitted via RF?

Have a bunch of D-Star gateways in our area that don't need to go out onto RF because they are all short range. I do have one D-Star repeater that I want to go out however, and potentially a couple of high power hotspots, but not all of the little ones (like my house)

Proposed Filter:
a/42.6295/-076.7045/42.2555/-076.23833 b/AF2A* -b/KD2EAT -s///D

Goal: IS to RF Packets that
fall within the lat/long (proven, has been working great for a long time)
Adding a buddy filter to pass anything starting with AF2A (Including the D-Star Symbol because this is a repeater)
Don't transmit "KD2EAT" specifically
Don't transmit any symbol with a D overlay.

I feel like the b/AF2A* and the -s///D are going to interfere with each other.

Example calls that I want to NOT TX

But I DO want to TX 

I'd considered doing it by "-b/*-B/ B/-C/ C" but I'm not sure which is the better option.

Thank you for taking a look at this,
