Hey David,

Just got one of those G4HUP adapters.  Any chance you could post pics of how you installed it?

Not at all trying to derail this question, but anybody know exactly what the connector types this thing uses are called?  I'd love to order some extras up from mouser or something...

Put it in a metal case and your issues will probably go away 
I wonder if you could test the "common ground" theory out by just using a wire to ground one jack to another and see if it causes any change?  If it does, you might be onto something but do note that there are lots of folks running this thing inside plastic cases.

On my rig, I've noticed that that volume control wire is pretty sensitive and if it rests across the wrong thing, I get a hum/buzz.  I say this 'cause in one photo the OP has the power switch wire near the volume wires.

Gavin, have you tried just jiggling all the wires & jacks and seeing if that changes the nature of the sound?  Sometimes a little percussive maintenance is all that is required :-)

A replacement for the Raduino

N6QWHAM@...
 

Having received a third hand Bitx40 I was faced with the problem that the Raduino was not providing the LO signal output.  When you know some stuff you can do some stuff so I ginned up a new source that provides both the LO and BFO signals and along the way added two VFO's, USB/LSB Select and a TUNE Tone. I now have this working on FT-8 and WSPR. See the details at http://n6qw.blogspot.com.

If you want the code there is an email link on the blog. Did I also mention it has a cool Green Letter LCD.

BTW I am also looking to add a 6 Meter Transverter to this project --still in the noodling stages. If anyone wants to sell a Bitx40 -- I have a crisp $10 plus US shipping for you. Same email address

There should be a link on the KD8CEC HamsKey sight for the mod and the software.

I2C Type Signal-Meter
Sorry David I did not mean the antenna analyzer, I meant   I2C Signal-meter firmware that goes in the extra Nano  board
in the Ubitx for a signal analyzer

You do not have a common ground. The mic, key, antenna shields and power should all be connected together. Put it in a metal case and your issues will probably go away

I would look at your power supply first. It is probably a switching power supply and the power getting out of it is not filtered enough. Try using a 12v battery as a test to see if the hum diminishes.

Looking at the circuit, It can be.  It will work on v5 too.  Just get the relay connections right.

Re: A minor bug in the ubitx circuit

The trouble is that even the earlier version of 2822 audio amplifier will have the same problem. It is best to make the mod for all versions. However, don't fix it if it ain't broke. Only if you are having a trouble with CW should this mod be tried.

short answer is it applies only to the v5, as the others do not have an LM386 in the audio chain. 


if you do not use CW, or you have a keyer with it’s own side tone, it would not be an issue and you could wait for other changes. If you want CW now, Oder the part. Note that it is surface mount device.  


I would look into other mods that are of interest like the age mods or digital operation, and add the needed components or wire and hardware for those if you are trying to save on shipping. Otherwise just order a selection of values pack, as caps always seem to come up as a required device in adding features to a radio.

Re: Constant loud hum or buzz on receive #ubitx-help #v5

 

Hi,

If you have a multimeter, take the analog connector off the bitx and then with the meter set on ohms, check to be sure you measure the pot value resistance across the yellow and green connections.  You can also make sure the center wiper connection vaires the resistance when moving the shaft with the meter on the yellow and orange set and the orange and green set.  It's possible there could be a cracked trace or bad rivet connection on the pot.

Also make sure the spring contacts on the connector plug look good when looking into the end of the connector.  Sometimes the springs get bent down so that they don't make good contact with the pins.

You do have the CW keying resistor installed so the rig doesn't go directly to TX on startup?

73,


Mark.

Constant loud hum or buzz on receive #ubitx-help #v5

Gavin
 

I just wired up my uBitx v5 and on the table it is outputting a loud hum or buzzing that intensifies when I move my finger closer to the ground wire of the volume control. I am new to electronics and radios in general. I asked a previous question about receiving Ashhar Farhan said I may have floating ground, but I'm unsure of how to test for that and how to fix it. Doing other reading, maybe it has to do with my power supply? I just have 12v 5a power supply from amazon, although I don't know if would cause such a loud hum. Anyone have any advice?

Thanks!
