v3.3 - RSSI moved to pin 7
                 - CH7 moved to pin 9
                 - SERIAL PPM fixed and on pin 8
                 - 459Mhz band fixed.

Looks like my fw has started quite a following haha. Cheers for the support guys :D As long as this system will be robust enough for my application I'll constantly update it with more goodies :)

@ Coyote good idea with the hopping set for the configurator. what do u guys think would be better ?

1. pre-defined hopping sets ?
2. random sets (random button)
3. boxes for each hop sequence

all the above ? lol

Pre defined hop sets imo, that way i would be on a specific set, then someone i fly with could ask me what set im on, knowing then if the select any other set, the channels are predifined so there is no clashes guaranteed ;)

With random theres no guarantee of clashes as with manual choice. But if you did what to do it manually, you can always edit your own sketches anyway

After trawling around for a while i finally came across Sanders GoPro tests on UHF band.



I knew there was a spike at 459 mhz from the GoPro so i wanted to check to see how bad it was. After all some are having problems on "run of the mill" none Uk legal UHF locking out with GoPro`s

As you can see the GoPro produces noise @ 433mhz -63.60dBm, 0.44nW, which seems a tiny amount, but as history has shown it can and does down planes.

On 459mhz the Gopro spikes at -70.56dBm, 88pW that`s over 6db less than 433mhz spike :) Giving 459mhz another great advantage over 433

Correct me if I am wrong but the real interference from a gopro is experienced when using the TV out and having it as a live feed cam...  otherwise its a non issue

btw have u guys seen melih @ flytron copied my interface idea ?

No Papa, its with / without TV out. Some claim the noise is less with tv-out used but there is no proof.

Not suprised Mihai, that's what Melih does.... He copies people and then sells it. nothing he sells is his own idea just a copy put into a good package.

Oww blatant copy, but with channel number choice

Mihai,
Yes I saw it as well.  I hope you get designer discount at his store for your configurator idea.

Papa,
I haven't tried my GoPro up against the OLRS Rx, but I have waved a UHF 500mW walkie talkie on transmit around it and didn't have any problems with the Rx.
It was a bench test with the OLRS Tx on 10mW and would have imagined the 500mW would have swamped it and affected the OLRS Rx if it was going to.

You're only jealous 'cos the voices aren't talking to you  :D

not for 459 lol :)

Im just off out in a sec to range test Thundeads code on 100mw, then on dummy load, both with Gopro on/off
