Meteor M2 LRPT Images Not Getting Decoded #41

Closed MihajloPi closed 3 years ago

MihajloPi commented 3 years ago

I had an issue of Meteor M2 not getting decoded. It seems that PLL never locks onto the signal. I thought I was receiving it on the wrong frequency so I tried both 137.1 MHz and 137.9 MHz with no success. Here's what I get when I read /var/mail/pi:

I resolved the issue. It turns out my tweet was actually too long so I just had to delete some characters in order to make it shorter. Now everything works perfectly as expected.
