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

You can start with these links:

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

Thanks.  I happen to have designed a board for that solution, so I just need to make sure it works :)  I saw that there is a cap/resister mod needed also.  I wonder if there are any more I should know about.  V5 should be here early next week.  Thanks, Dale

I need a set of harness and controls for my uBITx V3.  The original owner kept his already installed parts.  If you have a set to spare, please pm me with price and Paypal ID.  Thanks in advance, Dale

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.

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.

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!

I believe I do.  A V4, I think.  Make me an offer.  I'll look for it in the morning and let you know for sure.  Please reply privately.
