Cluster filter by Frequency

[HB9VQQ]

I am looking for a reliable way to filter out (hide) FT8 Cluster Spots. Currently, there are still some FT8 Spots getting through.

Maybe it would help if the Cluster Filter would allow excluding some Frequency ranges?

They already are if you check the bandplan file, but they are the agreed WSJT spot frequencies.

Not sure if changing them into a range could mess up the normal bandplan I will check

Thanks Terry, I see the entries in the Bandplan

Code: Select all

<SpecialFrequencies>
  	<string>1840000|FT8</string>
  	<string>3573000|FT8</string>
  	<string>5357000|FT8</string>
  	<string>7074000|FT8</string>
  	<string>10136000|FT8</string>
  	<string>14074000|FT8</string>
  	<string>18100000|FT8</string>
  	<string>21074000|FT8</string>
  	<string>24915000|FT8</string>
  	<string>28074000|FT8</string>
  	<string>50313000|FT8</string>
  	<string>3575000|FT4</string>
  	<string>7047500|FT4</string>
  	<string>10140000|FT4</string>
  	<string>14080000|FT4</string>
  	<string>18104000|FT4</string>
  	<string>21140000|FT4</string>
  	<string>24919000|FT4</string>
  	<string>28180000|FT4</string>
  	<string>50318000|FT4</string>
  </SpecialFrequencies>

It is an exact match, if the reported frequency of the Spot is slightly different from the nominal FT8 frequency there is no match. Maybe this would work better?

Example:
<string>7074000-707700|FT8</string>

Try it but I think it would break the bandplan as I said yesterday

[HB9VQQ]

I did not try as I think it needs a code change. Just an idea

Thanks

It's super annoying. I hate FT8 spots.

I'm using filtering on the node (DX Spider), and I've been able to get rid of almost all of them with this:

Code: Select all

filter0 accept by_zone 3,4,5 and not on hf/rtty or info ft8

I'll occasionally see one get thru, but it's not many.
