Re: Distorted RX audio at higher volumes

I think that I had a similar problem to what has been described. Someone suggested that I check to make sure that I wasn't using a monaural plug for the speaker. Yikes!! That was the problem!

Re: uBITX without Raduino
Some of you have missed my point. I do not care if the Raduino is not the same as between BITX40 or uBITX.
I have plans on using uBITX without the Raduino it comes with. Why pay for something I'm

Re: uBITX Wire Up Drawing error
even the broken resistor could slowly be salvaged by using a thin wire
instead of original wire.
it would be possible
However one side resistor woronal wire would hold it in position.

Ashhar:? We need a breakout just for uBITX.? Searching through BITX20 and BITX40 to find things on uBITX is a pain.? Please: can you do something about this?

Re: uBITX Wire Up Drawing error
I dont have a 4.7k? but I do have a 5.1K? I wonder if that is close enough?? But it is a carbon resistor.
What do you folk think?? maybe shoudl be patient and order the exact replacement.

Glad you mentioned this.? I am in the process of wiring my ubitx up and sure enough this and the volume controls were wired per the diagram and wrong.

Re: #ubitx replaced Arduino Nano gives a lot of I2C interference during reception

All my Encoder playing around has been on BitX and with interrupts.? Using Encoder library.
Maybe you could experiment by making a sketch by stripping out from uBit code that just includes reading

Re: #ubitx replaced Arduino Nano gives a lot of I2C interference during reception

Hi Sarma,
I tried both .1 and .01 on 3 different Raduino installations.
It doesn't make a noticeable difference on my 3 anyway. I'll put the .01's in anyway just in case.

Just for giggles, change your network card's DNS to 8.8.8.8 (that's Google's public DNS) and try it. Comcast may not have had their DNS refreshed or their DNS might have rejected it for some odd

Re: Faulty K1 relay
Not completely sure but I think it will work OK.
The only difference is that the coil resistance is slightly higher but I
believe this is not critical for use in BitX.
Why not just try it out?

Re: Distorted RX audio at higher volumes

TDA2822 does not have to warm up if it does is defective or it oscillates!
But the amplification is too high to the needs,
try to use agc on the audio or decrease the IC gain!
