+Notes:
+The satilite, acording to the tracker, will be flying directly overheard, but for this run the antenna will 
+always be north. I'm gonna do this for consistency
+
+Post:
+All I got was just static. there was a consistent, yet small signal at exactly 138mhz, but i dont think it was 
+noaa, as dopler shift wouldnt do it that much. the azimuth changed dramatically thorughout, so it could just be 
+that it was too far off, directionally
+it also appeared that there was ALOT of noise going on, so much that it seemed impossible the satilite was
+even there.
+Attached in the folder is 3-25-20-noaa19, showing the difference in signal strength on the waterfall in the 
+137 neighborhood, along with a recording and image

+The satilite should be nearly overead, i hope that doesnt mess with it, WXtoImg doesnt

+i guess, for this flyby the antenna's V will be facing south. I also measured antenna

+

+oops i guess?

+max elavation of ~8 degrees, this one is a lost cause

+5;29:22 i changed the tuning to 127.097 to account of dopler shift
+
+Post:
+definitly saw it, but it wasnt clear, i will edit the audio, see the original audio at ~6:05 for example
+Theres no image, and i cant seem to pull it out more, however i would consider this attempt a defintie

+We're switching to the one before, so were gonna be going out much later. Today im

+really tall antenna using a broom pole and the ladder
+
+The antenna is now on the really tall pole, its just a matter of waiting at this point.
+Its almost 7ft tall and it is daunting. Definitly not above the shed next to it but hopefully what bounces off the roof ill be able to get
+
+Post:
+This was a definite sucess! you can hear the clicks very clearly if you listen to the
+audio file, check after the 4min mark for clear times, at ~6mins in you can even hear
+clock tick tock! I need to rig this up better i think, put more tension on the cable cause thats creating alot of noise

+
+Post:
+Amazing! we got really clear signals most of the time! there were just random times

+Ill play with it some more tonight

+Another great flyby! Images are pretty acurate to the real thing, see the image titled

+Post:
+Great, little disapointed with the quality however. Excepted better results given the low horizion. Might just be the quality of my dipole
