Frank Skilbeck Posted April 8, 2020 Share Posted April 8, 2020 And if you have one of the earlier Spektrum radios, the US/EU setting is in the menu. Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted April 8, 2020 Share Posted April 8, 2020 We talking about banning something, because of something someone may do ? IF true, the mind boggles. Sit and ponder what someone may do with a model, best we ban it all now ? Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted April 8, 2020 Share Posted April 8, 2020 Ah right, best we ban everything thing then, someone might do sumat. Was nice while it lasted though. Quote Link to comment Share on other sites More sharing options...

Mike Blandford Posted April 8, 2020 Share Posted April 8, 2020 Posted by Andy Stephenson on 08/04/2020 10:46:40: Andy48 The document I referred to above appears as a email circulated by Duncan McClure South Midalnds Area Delegate to the BMFA and recommends that a local club adopts an embargo of open source radios as he maintains it IS possible to change the power settings using this system. I have now seen this email but it is an internal club communication so I won't put it online without permission. You may want to contact Duncan directly on this subject. Andy. I have over 20 transmitters, all running open source firmware. Apart from the 4-in-1 module, they all use a 2.4 GHz RF module that is closed source firmware provided by the original manufacturer and the open source firmware has NO access to the RF chip programming.

Mike Mike. I think that THIS is the sort of tweaking that Andy S is referring to. Info is out there if anyone really wants to do it, but as the thread in the link alludes to, it doesn't make sense to do it. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted April 8, 2020 Share Posted April 8, 2020 Still not open source is it, that's hacking the RF firmware or adding alternate non-CE approved aerials or hardware amplifiers! That could equally apply to any brand you care to mention, open source or otherwise. Edited By Bob Cotsford on 08/04/2020 18:05:33 Quote Link to comment Share on other sites More sharing options...
Mike Blandford Posted April 8, 2020 Share Posted April 8, 2020 Well, the FrSky XJT module uses 3.3V to power the SE2431L power amplifier chip, so you could only try to increase the output power by increasing the supply voltage to (the absolute maximum voltage for the device of) 3.6V. Then you could see an output power increase from 22.5 to 24 dBm, but only if you also increase the input signal by 3dBm (from 0dBm to 3dBm). Since the input signal is that provided by the CC2500 chip, and that can only output a maximum of +1dBm, you can't do that! In any case, the output power from the CC2500 is controlled by the (non-open source) firmware in the module. I can't actually see that suggestion achieving anything significant, while risking exceeding the max. supply voltage of 3.6V and destroying the SE2431L At best, I reckon you might get a 0.5dBm gain in output power, so increasing the output from 100mW to 112mW, which might get you an extra 6% of range!

Gary Manuel Posted April 8, 2020 Share Posted April 8, 2020 Exactly Mike. Not worth risking burning your hardware out for the minimal increase in range. So back to the original point of the thread - does open source present a higher risk than proprietary software? An analogy here might be - which PC operating system is at the higher risk of being exploited - Linux or Windows? Quote Link to comment Share on other sites More sharing options...

Stephen Smith 14 Posted April 8, 2020 Share Posted April 8, 2020 They could ban all transmitters to be sure and just fly free flight Quote Link to comment Share on other sites More sharing options...
