How would I updat the V6 and what do I need to do it.  Yes, I am a complete noob and old to boot!

V6 Cal instructions?

 

Any user instructions for the V6 firmware....No info anywhere about cal settings and so on......

+1 for missing BNC nut.

The 1/8" (3.5mm) jacks on the front included nuts, but the jacks don't extend far enough to secure the nuts on the front panel. Not a problem, but now I've got three tiny nuts extra.

Also, the only tools I needed were:

"regular" (neither large nor small) Phillips head screwdriver

"Small" (neither regular nor tiny) slit screwdriver

Pair of pliers/needle nose pliers 

The "small" screwdriver is needed to secure the supplied knobs on the control shafts. The "regular" screwdriver is for all other screws on the case, and the needle nose pliers are needed to hold nuts while you secure the speaker to the lid.

“Tighten the large nut around the BNC socket.”

 

I received two “large” nuts. Put one on the Encoder. Since both are the same size nuts, it would not fit on the BNC socket.

I hope the heatsink is clipped on. I have been running the radio continuously for a month now. No harm done.
In an earlier version, I was using a switching regulator. It was horribly noisy. I just took the lazy way out.

Hi all,

I have my V6 all hooked up and calibrated and have checked into a few nets with my own home brew mic, the supplied one got bad reports, however I have noticed that the 5 volt regulator heat sink is running at 142 degrees F or 61.1 C. That seems hot to me. Anyone else?

The packing slip for the v6 kit lists #17 Encoder nut, but does not list a nut for the BNC.

There is a photo that shows correct placement in the assembly instructions, step 4, 5 and 8 show the connection to the display board, not the main board.

 

 

I put mine together last night, went together easy & quick. I don't have a decent HF antenna, so I was only able to do some SWLing.

 

Only comment I have is the audio seems quiet - could be due to weak signals from compromise any, but I had volume control at 3/4 full and audio was only OK.

 

I'll test on a proper antenna over the weekend, but otherwise very happy.

Make sure your 8 pin connector is in the digital connector behind the
display not on the main board. Did that myself switch them and it worked
fine. Hope this help!

That’s great.  I went looking for V6 assembly instructions. I, for some reason never found these.

 

Thanks,

nice video - anyone watching is easily convinced that a medium wave broadcast has overpowered the nice rig you constructed.  with both original and new audio amplifier doing this, I am presuming it is coming through the front of the radio (if signal goes away when antenna is disconnected, this tends to affirm this). 

the filter suggested by Terry WA0ITP (we have corresponded on other topics) seems to be a good one.  if you have capacitors in the vicinity of those suggested (or you can parallel capacitors to get close) - you could construct ~ 1.2 uH inductors using wire and something to form the coil.  (the toroid is mostly to shrink the inductor).  keep in mind your filter must reject only this big transmitter's frequency, then pass signals of amateur radio interest. so if you can get reasonably close with the capacitors it may help. 

I was slow to notice that the uBITX has no provision to reject very low frequency signals (note in some circumstances experimenters may wish to tune in low frequency signals so that is part of the purpose).  note the signal has to be very large to cause this problem - hence very few of us have this problem.  if you are able to take your uBITX to a different location, with a long piece of wire for the antenna, you can confirm the uBITX is working (I can barely hear some amateur and other radio signals in your video). 

I am hopeful you will have a function radio when the high pass filter is added.

Re: 17M band bug in the firmware

 

I got it to compile but couldn't get it to upload until I changed the 'Processor' to 'old boot loader' then it uploaded fine. I'm glad that it now remembers the VFO frequency upon power up also thanks.

Herman,

 

Thank you for your enquiry.  The original mod comprised of swapping the pre-drivers and drivers for 2N2222's included cutting the original 20-ohm bias resistors in half.  Please confirm this with a forum search for 2N2222 modification.   

 

Forum user Allison mentioned the 2N5019 as a candidate for trial for this purpose, and I simply played a hunch that the resistor modification might apply with this semiconductor change as well as it did with the 2N2222 change.

 

Simply changing/altering the resistors and not swapping the original transistors will likely let out the magic smoke and release the socially-unacceptable words in a violent manner. 

 

73,
