There's a library that corrects for that (I forgot who wrote it, but a search should find it), or you can do it in code yourself. Basically, store the count in a static int and reset after 4 clicks

Hey fellow ubitx fans, has anyone had luck using a CNC encoder? I purchased one and get 4 pulses for every click of the dial. Not good! Thanks for any info! Barry K3bo

Evan, you are right the topic has already been raised by Jerry Re: Raduino mod to use the SI5351C (groups.io) (

Thank's for your answers have read the artical? you can translate in English. his command is different but do the same??? i (we) have to read operational notice AN619? p 19? cdt his command:

Gerard, The power level for the Si5351 is set in the ubitx_si5351 tab in lines 63 to 67: =====================Copied Code====================================== #if UBITX_BOARD_VERSION == 5 uint8_t?

Hi Gerard, It is used in the ubitx_si5351.ino, see extract below. It is set at 8mA for ubitx V5 so at the right value. I tested this setting on a V3 which defaults to 2mA and it improved the Rx and Tx

Michael, Welcome to the forum.? Please feel free to ask your questions here.? It also helps those of us who try to answer your questions if you can give us details on any added things to your BITX

In the meantime, I apologize for my English !! The problem is the cable that goes to the volume potentiometer which needs to be shielded! Replace the 3 cables with a shielded one and you will see that

Hello, I found this article about the spectral purity of the S5153 Clocks signal Apparently, there is a SetPower command to set the output current. The spectral purity of the signals can be improved.

Hello, thank you for being included in the forum. About two years ago I bought a BITX40 as my first radio before I even had my license. I applied some modifications like the ten turn poti but never

Ok got together with Bill KU8H on iPhone FaceTime and at 386 mile away he helped me do the adjustments and check voltage. The radio seems to be working as it should have seen the relay stick a few

Evan, Took the complete route, why would you do anything less :) Back in 2018 I got a V4, at the time the group was jumping with engineering solutions to the harmonics/spurs. Most of which were

That is what I did for my 7805. I already had some small TO-220 heatsinks. Although bolting the 7805 to a length of aluminum bar would likely work well too. Maybe in some situations there is a space

All, Here's what REALLY helps lower the dissipation of a 7805 - cut down on the head room. If you feed it 12V, that's a head room of 7V. The chip winds up dissipating E*I, or the head room (7V ) times

Robert, No problem with the questions. Your design of the 7805 voltage regulator should work fine.? I would recommend using a heatsink for the 7805.? For just the 5" display you should not need the

Hi Evan, I just thought of another question I had regarding the power supply for the Nextion display. (Let me know if I’m tiring you out with all these questions I’m throwing at you) ?what if I

Hi Evan, Thank you for your response. I was hoping that the filter might work. I think I'll take you suggestion on experimenting withe different configurations with the filter to see which one sounds

Hello Ultimately, optos may be the solution to all these sound pb (IC2, Nextion, Rotary encoders) To see here: untitled (vishay.com) (

Do you have any equipment or a well calibrated receiver? A couple of things that I don't tire of telling people Step 0: There is a myth that you HAVE to align your receiver out of the box. This is

Hi James, There is good advice already, but for finding a good receiving station you can also try shortwave broadcasts.? Radio Havana Cuba should be very strong where you are.? They are good for
