72 channels #99

I saw a new micro camera with vtx is coming out featuring 72 channels, can this be supported? link to product: http://tinyurl.com/zaq2s8v

kabturek commented 7 years ago

its shouldn't be a big problem to support - i could write it but i dont have any transmitter that supports it.

vadimus-ca commented 7 years ago

The L band already in the code seems to be different from the manual that came with 72ch AIO camera/VTX.

image Instead of 5362, 5399, 5436, 5473, 5510, 5547, 5584, 5621 it should be 5333, 5373, 5413, 5453, 5493, 5533, 5573, 5613

Is there some calculator available to find out what corrected SPI values to put in channelTable[]?

kabturek commented 7 years ago

it depends where you check ;-) https://www.rcgroups.com/forums/showthread.php?2592505-New-L-band-on-5-8Ghz

here are some tips about spi values: https://github.com/sheaivey/rx5808-pro-diversity/issues/75

vadimus-ca commented 7 years ago

Actually I already calculated those values, flashed and tested L band transmission, but thanks anyway.

Please pay attention to your local laws when messing with these "new bands" as they are not legal in the US. No sane US based company will sell you these VTX as the fines are quite large.

This has been discussed before... https://github.com/sheaivey/rx5808-pro-diversity/pull/86#issuecomment-246065178

If you are going to implement these new frequencies you need to wrap the changes in a feature toggle before I will approve any PR.

Thanks

vadimus-ca commented 7 years ago

Sure thing applicable regulations should be followed.

If you want the 72 chnanels, you can find the code here https://github.com/tipouic/rx5808-pro-diversity

There are also weather radars among other things on that band also outside the US.

https://www.sciencenews.org/sites/default/files/main/articles/102215_ts_radar_free.jpg < if you start to see stuff like this on weather radar, originating the popular fpv locations it's not very hard to predict how nice freedoms we will have in our hobby in the future.

Closing this issue as there is another fork supporting those 72 channels.
