Sometimes, processed pictures from Meteor are top down. mlrpt provides an -i option, to invert the pass. Is is possible, as for NOAA, to implement this into the meteor.sh bash ?

Better than doing a handstand in front of the screen, hi hi.

How to enlarge pictures at Meteor-M2 is it somewhere in mlrptrc?

No,

at /modules/meteor there is a meteor.conf file. Just a # in front of "resizeimageto=1024" (last line) and you're done with full resolution again.

OK1SLM commented 5 years ago

Yes, thank you, I've already come to that.

filipsPL commented 5 years ago

How do we know if for the given pass -i is needed or not?

49

it stopped me from doing meteor-m2 images www.ok1slm.cz

Ahoj Libor,

are you sure, that you have 49ppm Offset of your SDR ? Please double-check with a local radio-station, as they are quite accurate.

My good old Terratec SDR has an offset of 8 ppm at the requested frequency. 49 seems to be way to far.

filipsPL commented 5 years ago

please use bin/calibrate_full.sh script - it will give you a quite accurate value of your offset.

OK1SLM commented 5 years ago

použijte prosím bin/calibrate_full.shskript - dá vám poměrně přesnou hodnotu vašeho offsetu.

one small problem my antenna preamplifier has a GSM band filter

Hi, images from NOAA are doing fine

filipsPL commented 5 years ago

so you may want to remove the band filter (if possible) and the use kalibrate for some time (like 10-20 measurements over 1-2 hours) and take the average of the offset.

Reinstall RPI2: Debian 9 RTL-SDR Autowx2 mrlpt -1.4 Change RTL receiver: RTL2832SDR R828D TCXO 0,5 PPM

still black pictures or no pictures Look at the site there is a log www.ok1slm.cz

DL4OCH commented 5 years ago

Your setup will not work. Even a RPi 3B+ will not work with mlrp, as the computing power is far too low. If your going to decode in 3 steps:

  1. record a wav-file
  2. demodulate it to a soft-QPSK file
  3. decode it

It will take on a RPI3 approx. 1 hour.

Best,  Wilm, DL4OCH

Vaše nastavení nebude fungovat. Dokonce i RPi 3B + nebude pracovat s mlrp, protože výpočetní výkon je příliš nízký. Pokud se chystáte dekódovat ve třech krocích: 1. zaznamenat wav soubor 2. demodulovat do soft-QPSK souboru 3. dekódovat to bude trvat cca RPI3. 1 hodina. Nejlepší, Wilm, DL4OCH ...

And some idea? Now I put it on RPI3 B for the future RPI3 B +
