Amateur Radio Application?

Hi, how easy is it to addict the operational frequency of a 433.9MHz unit? I would like to use this on (approx) 438MHz as an amateur LoRA mesh network experiment.

Super easy, there is one constant you need to change. Change CH0 in MeshRadio.h. also for your experiment change NUM_CHANNELS to 1.

Many thanks! I’ll go forth and experiment with this, I’ve just got my first two nodes running.

Justin.

Hi! I’ve not bought the 433 modules yet, I have 4 x 868, however my friend 2E0EUI has bought 2 x 433 modules. I’m still struggling with the Bluetooth disconnects, I’ll buy the new ones when this issue is sorted which I understand will be soon. 865.2MHz is nice and clear here in Petts Wood though.

Shame the Chilterns are in between us, or we could try some DX :slight_smile:

Intrigued to find out what possibilities there are with amateur radio. I’ve got a great vantage point over Glasgow, and am swithering between 868 and 433 units. I would have thought 433 offered better range though.

I haven’t used my license in earnest in years, but I do keep leaning towards the digital communications side rather than voice.

I’m sticking to 865.2 simply because I don’t need an NOV to pop one at my repeated site and also it’s a long way from UHF interference from London Buses near my site!
