Hi Farhan,

great video on the new radio? ..... now that you have the PCB & cabinet done, any guess on availability and pricing ????

again? fantastic work...??? look to seeing it at Dayton FDIM

The wm8731 codec is controlled by the kernel, it is too complicated to do in by ourselves. Hence, it stays on the I2C bus.

Why couldn't the?WM8731 be put on the bit-banged port instead? And put all the other I2C devices on the primary bus that the OS knows about. Did the?WM8731 not like that either?

Ok,

Here is the long explanation. It starts with the WM8731, the audio codec. This is an a-social fella, doesn't want anyone else on his I2C bus. So when we started to add Si5351 on the I2C bus of rapsberry pi, WM8731 stopped playing along.

Now, our only option was to move the Si5351 to a second I2C bus. But, there was no second bus supported on the raspberry pi pins that we could use. So, we wrote our own software emulated I2C protocol on another pair GPIO pins.

As a result, many devices like the si5351, the real time clock and the swr bridge (there is one in the sbitxv2) are on a new bus.

The swr bridge is actually an ATTINY85, a 8 pin cutie that can be programmed via the Arduino IDE. This chip reads the reflected and forward voltages off the inline swr bridge. It has I2C address of 0x08. That is the one you see failing on your build, because the chip is not there. Why did I choose 0x08 address for the swr bridge? That is because I started to check out the ATTINY85 using an example from the arduino ide which used 0x08 as the I2C address, I never changed it afterwards.

Sometimes I feel like to solve this problem I would have to spend a week on it with the radio out of the box. However with Jack's dead failure it may help solve the intermittent problem by debugging it. Right now I'm getting ready to shift to outdoors mode..and other interests have absorbed me.
Do you guys suppose it's a communications failure? Jack, do you have i2c decode on a scope?

Will the V2 board work in the V1 case? Will it be available separately?

Thanx.?
Dan KD3CEU

Will it also be possible to buy the new V2 version but in the original large V1 box please? Many of us like real radio instead of door opener size…
Thanks
Petr

Any hints on pricing for the various options?

these are pretty big numbers for me.? :-(

Thanks Farhan,

most important in case of basic kit purchasing instead of full kit are enclosures V1 or V2. They are really precise, customized and hard to make beautiful housings. So it would be great to have them also available for sale separately.
I guess if someone would like to save some bucks then S-board + enclosure is the great option and Pi + LCD can be obtained from different sources.

Thanks,
Petr

Thanks for the reply. I just ordered it and I'm wondering what type of microphone you recommend for the Sbitx?
I read solutions from several experimenters. I'm interested in what you include with the full version.

We haven't "officially" opened up the sales yet! I hope to do it tonight.

Just one think > did I understood well that there is no good quality speaker installed as it is in UBITX V6 or SBITX V1 please?
Or am I missing something? :)
