Doomsday messenger - 3

Printed PCBs arrived, soldered the rfm95 chip and the gsm antenna on it with normal headers and now everything works nicely and is solid as well...

tested the range, and i can receive messages in a clear line of sight with a range of 2.5 kms+ or more wasn't able to test longer because 💀noida seems to have very less places with a clear line of sight near my home atleast... (cars and metro stations don't really matter they were in b/w my testing range... but huge buildings do block signals)
