    Hello again,Still no pictures from the .png files; only static from the .wav files, and I still don't receive the -map files. I have gone over all the instructions, and everything in my code seems to be as presented (except I added a ">" to the grep line for NOAA15 in schedule_all.sh). My .wav files are about 20MB and my .png files are about 4MB. My PassStart is exactly as written in the instructions: PassStart=`expr $5 + 90`When I type cat/var/mail/pi | less in my terminal (the same one I'm using for the code) all I see is a bunch of "~"s lined up vertically along the left side of the screen. Do I have to access the email somehow first?I found a different "sudo timeout..." instruction in receive_and_process_satellite.sh online:sudo timeout $6 rtl_fm...

I'll try it and get back to you. Unfortunately I am going on a month's vacation starting Sunday, so will be away from my setup until around the 4th of July.Thanks again for your patience and willingness to help. It's difficult for you, not knowing what I know and don't know about this project.Ed

    Hello, Michael!Thanks very much for your generous willingness to help me. But it appears that my code for that line already had all the spaces in the right places. However, I had my Raspi set to local time. I set it to UTC and eagerly awaited the next pass to see if I got a picture or a sound file. I was disappointed to find neither; the .png file was still a gray blur, and the .wav file just static. And I still do not receive a -map file at all.Questions: Might I be opening the .png file too early? That is, might the .png file appear in the weather directory before the entire file is received? Is there a typical length of pass? Can you suggest a reason why I don't find the -map file for any of the passes? The forms of the names of the .png and .wav files are just as you say th...

    First, Thanks so much for getting in touch!I have no experience with bash, and it is not clear to me what I should do. You point out that there is no space between the variable name and the date. But it is not clear to me whether there SHOULD be a space, or if I should REMOVE a space. My problem is that I don't know where the variable for the satellite name ends and the date begins. I had decided that the project was too difficult for me, but your note has me back at it.

    This is my 2nd time here. I now have everything debugged, and I find two of the three expected files in the weather directory (the ones that end in ".wav" and ".png") but there is no file that ends in "-map.png". What can I do to include that file in my weather directory?Also, I get the files for NOAA15 and NOAA18, but nothing for NOAA19.Also when I view the ".png" files, they are just sort of gray rectangles with no resolution. I have adjusted my antenna and hope that maybe that will improve the resolution problem.

    Thanks! I'll try that. But I'm having trouble with the bash coding, too. I've never done it before, and I keep getting errors.

    (I accidentally asked this on Step 6) I'm completely new to this kind of thing. Can you tell me how to find the call sign and location of my Ground Station? I live in Sarasota, FL. Thanks!

    I've never tried anything like this before. I followed all your instructions, but I don't know what to use for my ground station call sign or its location. Where can I find this information? I live in Sarasota, FL.
