No decode Package #20

Closed ct1esj closed 9 months ago

ct1esj commented 10 months ago

Do not decode any aprs package with SQL closed. Am I configuring it wrong? I have V0.3a

SQL=0 is mean noise on audio. You can test by open HPF or BPF mode.

I have been trying to play with HPF and BPF, some results were achieved this way with BPF open, it already decodes some packets, not all or a good part of them.

Anyway, it seems to me that SQL opens too late, SQL opens but no longer receives anything because it is the final part of the package and closes soon. I made a comparison with a Yaesu FT-5 and it turns out that on the radio the SQL opens immediately and the Lilygo remains silent.

I think I figured this out with my device at least. I could not for the life of me figure out how to get packets to decode. I'd hear them out the speaker, but very few would show up.

I set the squelch to 0, that seemed to help a little, but it still wasn't the volume of APRS messages I'd see using direwolf connected to my base station.

I accidentally broke the speaker's JST connector, so on a whim, I said, hey, what if I set the volume to max?

Sure enough, as soon as I set the volume to 8, packets started flooding in. I'd see Direwolf decode a message, and then I'd see it show up in the web interface.

I assumed the volume was for the speaker, but it appears that it controls the audio volume to the decoder as well.

Well, in my case I set the volume to maximum, 8. The squelch is at 1 so it receives and decodes everything. I also came to the conclusion that the volume level affects the decoding of packets. But as the volume is at maximum, I disconnected the speaker connector.
