A wonderful opportunity to get introduced to LORA

The product works out of the box. This is a great opportunity for anyone interested in learning more about LORA. The messenger consists of two units. A sender. A receiver The sender just sends out packets - "hello #". The number increments. The receiver displays the senders message along with RSSI. A great duo to test out range.

INTERESTING THINGS TO DO WITH THE DUO:
I live in NYC. My plan is to send a friend to the top of the empire state building with the sender. I will be at various locations throughout the city and beyond with the receiver. That would make a nice little experiment. I wish I knew more people interested in LORA around me to help with this test. It certainly would be unique!!

Armachat prototypes are Brilliant.

These little Disaster Radio units just do the job well. Great design and implementation from a developer who shows great talent.
Each unit works well and they communicate as you would expect.
My aim in now to add some 868MHz antennas and optimize the range, maybe also use a Gateway.
Thank you Bobricius, keep up the good work.
I look forward to seeing more of your talent.
