    I adapted the receive_and_process script to move the created files to a NASI created two mountpoints and put this on the bottom of the scriptsudo mv *.png /mnt/cifssudo mv *.wav /mnt/cifs_audio

    Somehow the lineTIMER=`expr $var2 - $var1 + $var3`was causing the problem I replaced the apastrophes and script ran without problem.

    wasn't it simpler to change the 'gt 19' (greater than 19) to 'gt 9'?

    My previous problem seems to be related to the power. I mounted a powered USB hub and at least have bigger files.Today NOAA19 came overhead and gave an wav file of about 10Mb. Unfortnate totally black. I found the following message in my mail.sox WARN wav: Premature EOF on .wav input fileSatellite: NOAA 19Pass Start: 2018-04-19 21:42:03 UTCPass Duration: 15:33Elevation: 59Azimuth: 74Direction: northbound..Satellite: NOAA 19Status: signal processing........wxtoimg: warning: number of lines in image exceeded 4096wxtoimg: warning: Narrow IF bandwidth (purchase upgrade key!), low S/N, or volume too highGain: 54.2Channel A: 2 (near infrared)Channel B: 4 (thermal infrared)Satellite: NOAA 19Status: signal processing........wxtoimg: warning: number of lines in image exceeded 4096Satellite: NOAA...

    I have the same, have wav files of about 10Mb but only have an one of about 21k of 88 lines.Even last night when NOAA18 crossed about overhead. Have a v-dipole in the attic with the open end of the V pointing south.Have read other people having antennas in the attic, is not ideal but should have had something more so far.

    I made it unfortunate not 100% yet.Files received are a bit too small, resulting in images that are too small and incomplete. Is there a way to manually start the receiving process? Most likely find the answer in the script somewhere. NOAA18 came overhead and still an incomplete image. Wonder if timing (scheduling) is wrong or something else.

    I removed the D1 in line 8 and than it verifies okay and I am able to flash the photon.Now have to setup some leds to verify if things are working like this. After that I have to go on the hunt for the LG-codes (Have a Vizio TV but read that they use the same codes as LG)But that will be continued another time because it is already way past bedtime ;)Is there another way to monitor if things are happening? Did change the deviceID and AccessToken in the programming on PebbleCloud, just not sure if the '?' should be included or not in the AccessToken.
