ah, so its a feature.. apologies... thanks

Hi Mike et al, Happy New Year! I have been meaning to comment on this as I have noticed a problem with the 'er9x-128_r819' but haven't had the time to do so. If you Long Left Press (+) and then goto the Controls Menu and on the bottom in the Mode Section... you are able to change Mode 1-4 but you ar...

Mike, I was speaking with FlipFlap the developer for URLS. He is going to contact you in the hopes of working together on a solution for APM and ER9x or ErSky9x to transport Mavlink via ULRS and have it picked up by the Radio for the Telemetry Screen. If we can incorporate the wherewithall to read t...

Same here!

I think at one point it did with c9x? Not 100% but I do remember something like that... old age is kicking in...

I tried a 220pf, 470pf, 1nf, 2.2nf so far...

It seems to introduce another sound...

The hum is prominent.

ah got it... kinda like the Taranis... It uses Samba too...

Thanks,
So this is all for the SkyBoard right?
Nothing to do with Xtreme or Stock 9x Boards?

I think this is the place... from what I can see.



Thanks for the image... Thanks for the info.

Will test today....

Mike, do you have a picture where you are doing this?
Happy to test a few options for your... really want to help solve this... its really bothering me

Sorry for the question, but what is this used for? I know what SAMBA is.., but is this an update, or some change?

My 3 axis gimbal for taranis/9xr came in.. I am going to fit it in my 9x... i will make it work.

Thanks for the update... out of all my radios.. the original MegaSound sounds the best... but out of the other 2 Xtreme's the 4.7uF Cap does the trick, little quieter.. but very clear and no to less hiss. I hope your solutions works...

Any update?

How is the hiss on this beast?
Can you hear it your vibrations [emoji16]

wow.. that is crazy... this is good for winter flying... landing in the snow... ;-0

See, that is why we post it with a "?"
Joao, Mike et al, will answer the question mark.

Thanks man!

I would agree...this looks much nicer...

Cutting those tracks for 9Xtreme is not necessary...
Now, I am almost 100% sure that you may need to put a dab of solder on those cuts to reconnect them?

When I get a moment I'm going to try adding a 47pF capacitor across the (complimentary) inputs to the amp. This might roll off a bit of high frequency, but also suppress some noise pickup on the tracks between the processor and the amp. Mike. It will probably take you as much time to show me (in a ...

João

I have a f-ring... didn't seem to do anything for me.

I just wanted to report back....
I tried the :

" .01 or .1 cap across the speaker connections "

with no success... Didn't change a thing, the in series method definitely reduces the sound output but always 1/2 the hissing/buzz as well.

Great mods Joao, well done..
How is that speaker, looks very good and like the fit?'
Sound good and clear?

Okay, I have tested the following. I have placed a polarized CAP as that is what I had in the 4.7uF range and that significantly reduced the noise by 50% I would say from using my ear. I then found a Ceramic Cap non-polarized at 4.7uF and that worked exactly the same but to the point of the smart on...

Understood, its looks deceiving with the heat shrink on the wire...
Here is the marked up photo.

I was scratching my head/brain about the cap and how the speaker PC board dual pads were utilized? Did you separate/cut isolate, the pads to allow them as you pix shows, to put the cap in series with the speaker? I'm just getting facts not commenting on the application there. The concept, if cap va...

Neat!... thanks for the information... If I could do it all over again, I would goto school for Electrical Engineering.

You see, i know enough to be dangerous... not enough to be helpful.
I saw this on another mod, put it into my radio as i had it opened.. it worked.. sounds great.. I will trust you on that and put in a non-polarized one...
Thanks for the information... Truly!

Thanks, understood... just thought the impedance if any, but I have a funny suspicion there is something different with my V3 and my v4 Megasound. I think there are a couple of Resistors on there and perhaps they are doing something to prevent this to work. I have pinged HC1969 to see what that is.
