Hi Gavin. I don't see a RF ground.?The (-)DC voltage is not a ground.? On most power supplies it is a common.? If connected to ground at the supply, it is connected to mains electrical system

Hello, in the file folder i put the v07 and v08 HEX files /g/BITX20/files/Signal%20Analyzer%20HEX%20files.zip 73s

Hello Group, long time lingerer, first time poster. I've had the uBitx V4 for almost a year now, and have used it for listening a bit, but not much. Recently I met a local ham (VE7PS) that really got

Please be sure to use the correct hex file, there are a number of them. Here is the FileNameInfo.txt listed.? Note that the hex file to use is dependent on the display that you will connect.? The

Did you remove the paint from all of the holes to insure good contact? Antenna jack, power, board mounting holes, jacks, case screws,etc. Twist your audio wiring together more as well.

Thanks Evan, I have downloaded the most current files (that you listed) and have uploaded first the sketches and then the hex files to see if there was any difference. The radio loses volume after

I did look at the nextion ? command set dim and dims, but will the in completely reduce the nextion noise

There are two system variables to control the dim function: 1. dim = 0? -> 0 = off. After reset you must set this again. 2. dims = 0 This will also work after reset.

Use a 2wire + shield cable between audio 8 pin plug and the volume control. The ground pin of VC can return back on the shield wire to the connector. But not to be grounded there at VC. Hope this

I have my radio in the chassis now, no more humming, but the radio stations are back. I can’t see any wires touching the chassis and the stations were there without the lid. And they are persistent

In my opinion using it just as a receiver is a bit of waste. It's an excellent choice as a qrp transceiver, but a Tecsun portable receiver like a PL660 is just more convenient with synch detector, AM,

Here is the link to the KD8CEC github for version 1.2 that has support for the uBitx v5: https://github.com/phdlee/ubitx/releases/tag/v1.20 I believe that the Nextion tft files link is on this page:

Yep Curt, I may have to go that route, but I already have a nice case on the way. What I am trying to avoid is going to my junk box. Maybe somebody will have a spare. Dale [email protected]> wrote:

Dale Here is another thought to explore. Many of us buy the case from amateurradiokits.in. Sunil also sells a companion set of harness. This may be the most turnkey approach. I like the end result.

I don't know about anyone else, but I would rather get the harness and controls all made up.? It is a pain to crimp molex connectors even though I have the tool.? So, to get back to the topic;

I wish there was some to disable the dimming mode of the nextion display, maybe contact nextion to see if this is possible?because the choke dose not get rid of the noise completely!

Hi Cory, They are Molex Type KK KF2510 2.54mm Connector Sets (2-20 Pin) Housing+Header+Crimps (Molex KK Style)

That is raw. You can hard wire the radio and have it work just fine. -- 73 Dave k0mbt Raduino bracket and Ham_Made_Keys ( http://veloliner.com/ham/k0mbtkey.pdf )

I wrapped all 4 feed wires around a toroid core. I figured that I didn't know which wire was emitting in common mode so they all got the treatment. Made the installation neat using up the excess wire.

Absolutely Mike! With the inherent stability of the uBITX it tunes nicely to the exact frequency, zero beat, and no problem in receiving AM. Actually, it is somewhat better since the selective fade is
