I do have them but scan is showing no results. I'm using a homemade
antenna that is giving 90-100% coverage with the windows app
so I'm rather sure this is not a signal strength nor snr issue.
Here is my freqs file
T 533143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 24
T 533143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 24
T 569143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 30
T 569143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 30
T 587143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 33
T 587143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 33
T 551143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 27
T 551143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 27
(entries repeated just to try out different combinations)
Now, I know for sure there is a 1seg broadcast at 587143 KHZ
, that's the one I'm getting with the windows app but scan on
Linux keeps showing no results.
I'm attaching the verbose scan output (I have also tried with
-5 with similar results):
Best regards
