Re: Micro-BITX ... Lost in post ? Possibly
Just got Paypal notice that ubitx has shipped. I ordered on December 13. Tracking says that with my DHL shipping it will arrive in Michigan on 1/16. KC8IFH

Re: MAX9814 integration to uBitX
Thanks Herman, that's what I'll do.
I will report back when I get it done.

Hi Dave,
That's what I did with my Bitx40 which has the same circuitry. I
addition l've put a 10k pot between the MAX9814 board and the C on
the Bitx, so I could define the limit.
Transmitting is much more comfortable now ...

I am so happy to have mine. It is together and apparently working. I had a mistake on the tip/ring connections for my Mic. Fortunately I plugged it into my dummy load.? I have not had a QSO yet. ?It took me a while to get my antenna tuner to work. I ordered a new switch for it. I also ordered a QRPGuys, tuner . But it is working. ?I have a G5RV but expect to put up a dipole soon too for 40 meters. I have a 10 meter vertical read to go. Time to order some coax.?
I payed for DHL to the US (Texas). It was ordered around 9pm on Dec 12.?
It arrived 65 hours after the ship notice at 4pm on the 11th of January. Having sent stuff back and forth to Thailand 30 years ago I call this progress.?

Re: #ubitx Digital & Audio 8 pin connectors
#ubitx
You could just remove power from the IRF510.
Then it's safe to play with transmit, no dummy load needed.
I did that when debugging my transmitter, everything works normally till you get to the IRF510.

Anyone know where (in the US) I can find those connectors (female) and the crimp on pins?

Re: AE7EU Top Level PCB Mod
Regarding putting diodes near the front end of the uBitx, this post is worth reviewing: ? ?? /g/BITX20/message/35656And this thread, which continues the discussion: ? ?? /g/BITX20/message/37330So that ADE-1 attenuator might work better if placed after the 45mhz roofing filter, or somewhere beyond that. But up front where we have the whole world of RF coming in, the diodes may create harmonics of a 50kW AM broadcast station across town, harmonics that will show up in the ham bands. Vince wrote: " Before smoothing, at moderately high RF fields the RF was setting off the Halon alarm!"
Exactly what do you mean by "smoothing"?
Do you figure the diode ring mixer was creating harmonics?

Re: Bitx40/Raduino no power - help
Yes, thanks Raj. I was confusing the pot numbers...I was adjusting RV1 not RV136. Found the problem to be a dead Q13, which seems to happen a lot!

Re: Sotabeams CW filter problem
I tried the 90.1 uF cap in series with the AF filter output but it didn't help.
My filter is always on, but there is no noise from it when it is bypassed, so I don't think it is generating noise on the power line.

Re: AE7EU Top Level PCB Mod
Ok - found a circuit on this group that removes my confusion.?
?You have it wired correctly Martin!
The data sheet is not very clear with nomenclature - if the PIN numbers were indicated on the circuit diagram then it would be far less confusing!

Sorry I wasn¡¯t clear, ?but I think there may be an error.? The data sheet confuses the matter because different nomenclature is used in the circuit diagram from the pinout on the chip.? I believe the labels correspond as follows: L = RF, I=LO, and R=IF.? But I may be wrong!? I have not used this package before.
Mike Hi Mike,
Check out the datasheet for the ADE-1 here:? .? Page 1, bottom right side for the electrical schematic, you'll see the "I" pin has a DC connection to the diodes and then to ground.? This will forward-bias two of the diodes, and reverse-bias the other two.? A current limiting resistor (R14 in this case) limits the current going through the diodes.? I picked 1.2k randomly, it might be 1k-100k, I'll have to play with it I'm sure.
