I was unaware that this type of tech even existed, ive been looking for off grid comms alternatives. This is great! 10 stars if I could.

Love the app, I would just love for some support for black and white modes like robot 8

Extremely cool quite a few options for sending images via sound pd240, Scotty DX, and waase sc2 180 work best for high quality images whereas Martin 2, pd50, Scotty 2 and robot 36 are going to be your fastest options

I really wish that it had a way to automate the transmission of images. For example, you select a folder and one by one it transmits the images. I use it to transmit radar images to my other phone via radio. Very good app, add more support!

I downloaded after seeing it work on YouTube. However all I have is a ht. reading some other reviews I see others are using it with their ht. I wanted to ask them how. Have an uv 5r. Sadly I picked up android just for this purpose. And you can't comment or ask questions on comments in play store. Not huge fan. Can't even see where you can just receive without sending. Also there is no users manual leaving newbies ideas which is the best mode to use. If anyone knows how to help... please?
