Thats the one I was looking for! THANKS!!!!!! Smules across the wires, Rogier

I got one bitx qrp rig unfortunately its audio was too low and by mistske it is totally mis aligned. How can I re align to usb mode all bands ?

Ill fix it in an hour. Watching the cricket league finals now. - f [email protected]> wrote:

Thanks Tom, I made progress by loading the original software and then tune into a station on using the correct sideband. Then go iinto the setup mode and adjust the BFO untill the audio was audible.

Farhan if you go down the page to the new board schematic in the circuit description and click on it that link brings up the Raduino schematic too. That needs to be corrected also, otherwise

.. Those are my principles. If you don't like them, I habe another set of principles too! - Groucho Marx [email protected]> wrote:

I suggest waiting for Allison to report back on what she recommends before doing any?serious surgery.? In the meantime, perhaps try Farhan's v4 changes to bring up the power on the high bands

You can expect upto 20 watts output from. Rd15HVF1. I have tried those.You will be nominally louder, not more. I'd rather push the PA to 25 or 30 volts instead of RD devices. You will be 30 watts or

“RD15/RD16's can be stuffed as an alternative to the IRF510's” other than the extra cost, what difference should one expect with RD15HVF1’s?vs RD16HHF1’s?, & vs the IRF510’s? re: ?needed

Good. Having the Nano socketed will mostly solve a lot of problems. With the audio connector integrated, the Raduino could incorporate all front panel controls, with mounting holes for the panels and

Dave You are in the right place.? The u is actually a ? as in micro for micro controller.? Which is Ashhar's most current and first multi band radio.? The original BITX was a single bander so the

I would urge you to build it without a pcb. I think a video will help. I will try getting one out soon. - f

Ashar, have you or any other members of this group designed a pc board or kit for the new audio amplifier circuit? I would like to build it but have no design skills. Thanks, Al KB4RA

This Forum is a general place to seek help on the Bitx40, Bitx20, and the uBITX, hence the "Bitx20/40/u". Like they say, the art of a good answer is a clearly-stated question. Many of the regulars

Raj, I've seen many many references to the uBITX here. Allison is working on a mod to flatten the power curve across bands. So, I am confused what does the "u" stand for in " Bitx20/40/u"?. This is

HI Greg Its BFR106 I might have duped the R. ITs a 5ghz low noise critter. I'll put the datasheet in the files are under my call. Allison

Incremental improvement is a very good thing.? Very good Farhan. I'm a fan of that audio circuit, Been using it and variations of it for at least 35 years and it never fails. Saves a lot of pain over

One thing you may wish to do is put terminals/ a connector to bring out the I2C pins SDA and SCL since many people are using such devices in the uBITx.? There is a nice blank spot on the board next

The new boards have the arduino socketed on the other sidd. - f

Nothing needs to be changed in the bias. The dc circuit remains the same. - f
