[Error] Rarely getting Meteor in Color #122

Open flewid opened 3 years ago

flewid commented 3 years ago

For some reason in 2 weeks I have only received 2 color Meteor, they are almost always black and white.

I've tried 100, 144, 248 for the samplerate from that other thread just to see if that made a difference (it did not).

Here are my details:

Location: Eastern Time Zone

GPS according to google maps:

45.962608

Dongle NooElec SmarTee XTR

You might try lowering your SUN_MIN_ELEV in .noaa.conf to something lower. I have mine set at 1 and I'm getting at least one daylight image a day from Meteor. I'm in NE Wisconsin, so I'm low on daylight here too.

@tegwilym thanks, will try that

flewid commented 3 years ago

thanks @tegwilym setting it to 1 has worked!

tegwilym commented 3 years ago

thanks @tegwilym setting it to 1 has worked!

Great! I'm still learning the tricks of working out the different things in the configuration files. Glad I've learned enough to give some tech support! :-)

reynico, looks like this can be closed. I'm not sure where I do that or if you need to do that?

Thanks, Tom

mine is set to 10, in fact I get black and white images, do you recommend me to set it to 1? METEOR-M220210130-073742-122-rectified

Yes, try a lower sun angle. You can even us a negative number I’ve heard. I have mine set to 1 and I’m getting color on both meteor and NOAA again. Here is the Great Lakes area from yesterday morning. Tom
