    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Hey I was wondering what laws apply this Tx and Rx system.

OrangeRx OpenLRS Tx Module
Compatibility: 5-pin Futaba compatible module-based transmitters
Frequency: 433MHz
Voltage input: 6.8~12VDC
IC: Atmega328P
Power: 1000mW

Now im assuming i will need my Ham license to use this Tx. But my other questions are what power limit do i have and is there any other restrictions? Thank you in advance.
