Re: How to get rid of Local FM broadcast stations #ubitx

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 ground, not a good RF ground.
Since you are in a metal chassis, remove the paint to have a good connection between the chassis and all the connectors including the 4 PCB stand-offs. Then bond the chassis to your RF ground.
Also make sure you have a proper size fuse inline between your power source and your uBITX.

The green/yellow/orange bundle to your volume control: Move that forward and down close to the chassis to minimize coupling from the encoder and USB

Rgds,
Gary

uBitx V4, nextion display and other mods #ubitx

dwhacks
 

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 me interested in radio again. I have been studying for my license on and off for the last 4 or so years, and now after meeting VE7PS I am making the push. I will be taking the test early January 2020.

ANYWAY, the reason I'm writing, is I'm a tinkerer. and I've done most of the mods to my uBitx; nextion display, ND6T Stockton Bridge SWR with the extra arduino for S-Meter and SWR. Ive also got the small AGC board from kit-projects.com.

My question is; after installing the AGC and the S-Meter, where should I connect the S-meter? it says "Vol-high" but the AGC board has an S-meter pad. The AGC instructions state, that for a V4 board to connect the AGC V to R70 through a resistor instead of through VOL-HIGH. So it seems I have 3 places to choose for the S-Meter: Vol-HIGH, R70 through a resistor, and S on the AGC board.

Does anyone have any ideas?

Re: Nextion Question

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 the last part of the name indicates the display.  the file ending in _16P is the CEC software that will work with the original display.  The file for the Nextion displays end in _NX.  The _NX_S is for use with the I2C connected separate S meter.  Go to the Hamskey site to find out more.

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.

Re: Nextion Question

Dennis
 

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 these uploads and does not drive the Nextion. I really don't know what to investigate next. The radio works fine with the original software and display. BTW the last time I uploaded a hex file I had the original display plugged in and it worked just fine even though the file I uploaded was for the Nextion display. That really doesn't make sense to me.

Regards,

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.

Re: uBitX as a Shortwave Receiver?

iz oos
 

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, excellent SSB, excellent AGC, and you have the AM Airband as well. And plenty of volume too.

I believe that the Nextion tft files link is on this page:

Be sure to note the information in the v1.2 zip file that describes the different files in the archive.
