That looks like a good approach, and resembles the kind of MOSFET muting used in KK7B's R1 and R2 receivers. John K0JD

We never got that far since we weren't getting anything out of the raduino, or not that we could tell. It was one of the tests Gordon wanted him to do but it didn't happen. Vince.

Oddly, that didn't work for me - first thing I tried. No change in tone. John

So you contend that Continuing to upload sketch after sketch in to an obviously broken Raduino ..:that will have to be replaced ...and not troubleshooting the remainder of the hardware to make certain

Did we verify that the 12mhz signal is working, did we hear this? If this crystal isn’t working we can generate any signal into the BITX40 but we will have no luck receiving anything as there will

C6 is indeed supplying the dds signal to the bitx40. Clk1 is unused and not doing anything in this radio. uBitx probably will use this. You still have L4 on your board where the bitx40 is connected to

Tausciam, Would you be able to inspect the bottom of where the DDS enters the BITX? So we are sure there is not shorting there? Or maybe just make some picture of the top where you connected the

John (and all), I have the exact same issues with my uBITX - Pop, poor keying both hand key and paddles.? I don't have an external keyer to test it with but I'm going to make a solid state (2N7000)

?I managed to get a paypal thing off to tausciam after he gave me some coaching on that part----he'll pack it up and ship it slow-boat. It only has to go about 300 miles between us and when it gets

The board is raised up with the standoffs. Nothing can touch it. As far as being connected backwards, there are two grooves on the edges of the connectors. They fit on rails on the board. So

?Happy to help if he can connect with me. Vince and Ron are on the right track --- I too have suspected something might be shorting it out on the bix board and if so, will be an easy fix. But

Found your picture of the DDS module. CLK0 ping and C6 going out to the BITX board. Can’t see it very clearly but C6 might have bad soldering…. Can any of you inspect same picture and see if I am

Hi all, Just finished my B40 build with the RTC install. I get spurious characters on the date time line and the next line on the display, also the frequency change is very sluggish. If I remove the

You have a link handy? Thanks, Roy WA0YMH

Hold on we are getting closer ! Could you verify underneath the bitx board where the DDS signal get’s into the board that there is no shorting of the pins? And it is not accidently connected

I've resisted this from the start....but I think now I'm at a point where my only options are to trash it or have someone else look at it. This has gotten me so iffy that I'm not even going to take

Yeah, I did catch that. The "disconnected" part I was talking about is not the display, but the wiring to the BitX board, buttons, etc. Mainly the connection to the DDS port on the board. If it is,
