Thanks a lot Allison
Just wondering why the same heating issue is not there on other bands.

Its a shame to give up your built &  fully tested board now?

Why not buy a V5? Or maybe wait for the new V6?

May the peace be with you.

I appreciate all the great design and modification efforts that have gone into the radio but it just too much for me. As a receiver it's performance is quite good. I will be offering it for sale in the near future. I'm not sure what all I will include in its sale but anything I won't need that was purchased specifically for the uBitx will likely be included.

I will be waiting for the new QSX from QRP-Labs. I built the Ultimate 3S and am very pleased with its performance and feel this is the best move for me. I want to thank everyone for the re-engineering, guidance, and support for here.

I'm glad to hear you're enjoying the Ultimate3S kit. 

QSX... huge project... I'm working on it every day and making steady progress. Thanks for waiting. The wait will be worth it. I'm posting details as I have them, on the QSX page http://qrp-labs.com/qsx

I do not have pictures, however I have seen just the reverse:  When first keyed, the spurs appear, then fade as the transmitter remains on.  This is with or without an audio signal.  Suggesting that something is changing as the circuits warm up?  Thing is, I have seen this every time, even after letting the rig on for a period of time.  I at first attributed to an issue with the SDRPlay SA, and that may still be the case,  After reading your post, not so sure.

Re: v5 board original FW

Evan Hand
 

Thank-you Laurence!

This was not for me, rather for mrjohnac that requested the "FW" for the version 5 uBitx.  I assumed that FW meant Firm Ware, and I added that it was not a straight download, rather an Arduino sketch file that would need to be compiled.

I will look into putting this into the files/wiki sections of the group.  There really is no easy way to find the information, unless you have run into it before (I had saved the link to the GitHub repository when it came out from Ashhar).  Doing a search on either the posts, files, or wiki I did not find the v5 firmware listed.  Same with using the link on HF Signals: sent to the version 4 software.

All this makes it difficult for the newcomer to the uBitx.  What is really needed is someone to take on the task of keeping the site up to date.  I am not sure if there is a single person who takes on this role.  I would think that at least for the basic stuff, like when new versions go into production, that the task would be done by someone affiliated with HF Signals (maybe someone who has it as a part time paid job?).

If I am incorrect in the above statements, then please shed light on where I am wrong, so that others can gain from the knowledge.

Again, thank-you Laurence for posting the .hex files!  It is volunteers like yourself and others that are at least keeping this afloat. Now we need to post the program and process to download it to the uBitx.

The issue I spoke about on the V4 with 20m and CW FCC tests

Laurence Oberman
 

I had mentioned this issue I have on the V4 that looks like RF
coupling or leakage when testing CW on 20m for FCC compliance.

I don't see it with SSB but if you transmit for long enough spurs will show up .
See the document I shared.

I only just got my Axicoms to replace the relays.

Strangely enough not seen on 15m, 17m or the higher frequency bands,
also not seen lower than 14Mhz.

Other than that the V4 has been fine, now replacing with V5 and my son
gets the V4.

Question is who else has see this.

I had a issue like this and it was because I selected the wrong hex image for the wrong display.

Re: v5 board original FW

If you clone that github repo, you can built it yourself.
Move all the .ino files into a folder called ubitx_v5.1_code
Open the main file using the arduino ide in that folder called
ubitx_v5.1_code.ino
Then build it and program your Nano

Can someone send me a copy of the original radio FW for a V5 board or a location that I can find it. I read, I had ideas, I thought I knew what I was doing, it's gone and now I just want to get the radio working.

As you have probably figured out, the schematic for the Bitx40 is at the top of this page:
    http://www.hfsignals.com/index.php/2017/11/23/bitx40-circuit-description/
and the assembly instructions here:
    http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/

The diagram at the top of the assembly instructions looks sort of like a photograph,
but it is instead computer generated from a board layout program and so
some of the parts and connectors do not look quite right. 

The diagram shows the Raduino oriented such that the display would be facing you,
but the display has been removed, and the diagram does not bother to include
the 16 pin display connector on the upper left.

The connector you are asking about is on the bottom.
Pin 1 is on square pin on the far right side, the diagram shows orange, red,
brown and black wires coming from that connector on pins 15,14,13,12.
The yellow wire from pin 16 is not used, but put tape over the end of it because
it will have 12 volts on it and you definitely don't want that touching anything else.

The early Bitx40 kits had a 5 pin connector on the back of the board (as shown in
the pictorial diagram) for that connector for pins 16,15,14,13,12, and we would 
then plug in a wiring harness to that connector with yellow, orange,red,brown,black
wires coming out of it.

But now the uBitx has come out, and for the uBitx all 16 pins of that connector
plug directly into the uBitx main board without any wiring harness.  
All Raduinos now get built the same, so all Raduinos have 16 right angle pins
soldered into the back of the Raduino there instead of the old 5 pin connector.
When using such a Raduino on a Bitx40, you should plug in the 5 wire harness
on pins 16,15,14,13,12 of those right angle header pins, it will mate perfectly well.
The unused yellow wire should be on pin 16, which is the furthest left in the pictorial diagram.

The Raduino first shipped in Dec of 2016, all Raduinos ever shipped since then
have been physically identical except for that connector.  

Raduinos shipped with a Bitx40 have Bitx40 firmware programmed into them.
this is different from the firmware on a Raduino that gets shipped with a uBitx.

Jerry, KE7ER



But it is correct, once you get the raduino board oriented correctly.
You are looking at a raduino board that has the display removed,
and the 16 pin display connector is on the upper left.
You should be able to see the

I got this kit straight from HF SIGNALS.

Check the adjustment instructions at HFsignals, but this sounds correct from memory  for ssb with no audio input. The current should go much higher when applying enough audio or doing cw. Unless you have a key, use a piece of wire to short the cw input to check your transmit current and output power.

Thanks, Sam. Now, I have no special attachment to the pictures, as this was someone else's program anyway :)   I'll put this on a screen and give it some exercise.

The S-meter hasn't been hooked up yet on this build though it will be.  Regarding art design, a tiny mushroom cloud would be a nice touch for signals above +20.
