Re: Replace 5V regulator

Bob - Have you checked the voltages as per my last post? The regulator related to the display and other circuitry that needs 3.3Volts is the one that you posted earlier that has the yellow 3.3V text. The pin there is the one on the far right of that chip that should read 3.3 Volts. As for the voltag...

I welcome any suggestions you have, fore I need leave it for now and work on the troubleshooting it more tomorrow. Check that the track you have cut through doesn't have whiskers on it shorting to the next track. You should have full supply (battery voltage) on the red wire with respect to the cent...

As I said these RF thing is weird. Any 'scientific' explanation beside the servo is jinxed by the 2nd floor? :lol: Possibly a small change in the whisker position has done the job.

Re: Taranis - speaker buzz

I take it that the buzz is still there? There has been some success, using a 1000uF cap near the amplifiers ...

Re: servo jitters by Frysky Rx antenna

Don't forget that having the 'whisker' antenna close to anything metallic will detune the antenna, along with creating a 'shadow' where the antenna will not see the transmitter. Not good news :(

Re: Taranis - speaker buzz

Has anyone managed to work out if the buzz is caused by the switch mode or pickup from nearby data lines, or is it all down to RF interference from the RF module? Today I added another two ferrite clamps to the same leads. I keep thinking that much of this may be down to common mode RF getting into ...

Re: servo jitters by Frysky Rx antenna

If you are using a telemetry receiver, then you will have to bear in mind that the RX also has an inbuilt transmitter that communicates back to you. One of your 'whiskers' is a transmitter and a receiver. Best solution would be to move the whiskers well away from servos, electronics and other wires....

Re: Replace 5V regulator

The decision is yours. :) The switch mode that I linked to earlier seems to work fine feeding two servo's in one of my models. I just have a thing about trying to avoid switch modes wherever I can. The actual gain by using a switch mode in this case I feel is not enough to warrant its use. If you go...

It works fine where I am using it.. As for use in the TX. Nothing has changed my view on the use of a switch mode in the ...

Another Viewpoint

I used to make use of the Haptic modification before the voice card was added. Since that time I haven't used the Haptic at all, as the voice announcements are far more affective. So if I was going to modify another TX I would leave out the haptic addition.
