Hello, Despite having modified my mounting and added some elements (Diode + resistance +capacitor) on the mosfet from the foot 25 of the arduino (T/R), I still have unpleasant noise during reception/

Hello Barry, thank you for the information Datasheet here for all https://www.bourns.com/pdfs/em14.pdf cdt

Evan, Installing an optical rotary encoder doesn’t seem that simple. This still requires hardware changes with the addition of a splitter and/or soft changes. PB of numbers of PPM For the moment, I wi

Evan, Nice to hear from you. yeah, I tried the capas on the encoder. But as said before, the switching signal of the encoder (square signals) go on the side of the amplifier. These are just a few mill

Good evening, My encoder causes snaps in the top speaker. At the oscilloscope, we can see a few millivolts of the square signal caused by the rotation at the entry of amplifier I tried to move the gro

Hello Vic, Thank you for your comments Yes, I will improve all that. I will change the potentiometer cables and put shielded. Then I will test the Smeter with the manager Ubitx. On the diagram, as M0T

Hello, it’s hard to remember At least 2 a soundblaster and a graphics card. After that, I can’t remember whether a card was needed for the first CD players. The first x86 IBM had no hard drive, 2 flop

Hello Evan, I tested the amplifier. It’s working fine. I need to put shielded cables on the potentiometer because we’re picking up the 50Htz and it’s picking up a little bit. For Smeter, it works, but

Hello, Yes, not in the good order. pb native language for me CAG = Contrôle aautomatique du gain for you AGC =automatic gain control it’s a bit difficult for me, because I have to use "Reverso" each t

Hello Evan, Hello all I’ve finished turning up the amplifier. I’m going to test the amp and smeter to morrow. I also ordered BFR transistors to replace the 3904 I took both CMS and TO50 box components

Hello Vic, Hello all This day I added on my PCB where there was a little room for the LM358 circuit and its components, this to make the smeter work. It doesn’t take up a lot of space, as you can see

Hello, Since I went through this forum, I find an important batch of changes So I have a suggestion, and it’s just an idea. I think it would be wise to make a list of everything that could have been c

Hello, I have a much larger Nextion screen, but it does not have the connection with the 4 Wires (-,+,TX,RX) Everything is done on the tablecloth 40 points. I would like to know if there is an adapter

Hello Evan, hello Mick and all others Evan, It’s crazy, I ordered the amplifier on Monday night and I’ve already received it. Quite a logistics at Jeff!!! I’m thinking of installing it directly on the

Hello, Thank you all for your explanations As soon as I finish my tests I will keep you informed I don’t know who is updating the Wiki, but it would be nice to do it because I think there have been a

Hello Jonas, Okay, I get it, it will be necessary to add a nano + connect the 5 wires, so I think to add mass and alim for the nano, resistances and capacitor. The capacitor must be connected to VOL H

Hello alll, Hello Jonas Yes I know that "we can add a nano and a 2nd Nextion". The basic question is: "how to operate the Smeter on the main Nextion". If there is only one Nextion to manage the comple

Hello, Is there a solution to the problem of Smeter that is either zero or full? That is my case. On hamskey I saw many cases, but no answer. We are talking about a connection on the A7 of the arduino

hello Mick, Thanks for the information. Yes, today I worked on the ubitx manager for the Smeter and saw that there was an option to save these settings IFS My calibration and BFO setting must not be t

Evan, I think I found a solution to a pb I said that sometimes I had to reinstaller ubitx manager to communicate. In fact, I think the ubitx should not be on, but simply make the connection with the U
