Some time ago I was reading an old article of a USA HAM and, having an old CA3089 in the drawer, I got the idea of ​​developing a small circuit to take the reception signal from the µBITX IF and obtai

Give it a try. It should work fine on 3.5. It just won't use the whole screen.

I use a board with ADS1115. Also, I feed the LM386 with 12v. This offers a more reliable reading than pin A7 on the Arduino Nano and widens the voltage range at the output. On the other hand, you have

The output signal "S" for use as "S-meter" is honestly too low: the variation goes from few mV to a maximum of 1.7 / 1.8 V (the max with S 9+30dB (-43dBm in antenna) rf signal level), this severely li

I installed my kit projects AGC board carefully in my v5 ubitx. My audio dropped appreciably in all settings I did not take any readings, just my ears. So, I un-installed the AGC board and jumpered th

Elecraft has (or used to have) a simple S-meter calibrator that put out a signal that was supposed to be S9 and was pretty inexpensive, if you really need to have accuracy. Then you could check it wit

Good morning I can no longer find the specifications of the s-meter of the sketch of eZall with encoder I installed his sketch on my bitx40 and it works really well! It is already set up for s-meter,

Rereading your original post, I am not sure which version of the KD8CEC sketch you are using. Note that the versions with the -S suffix are not appropriate unless you add the second signal analyzer Na

Dale, hello. I may be able to help out. I too had that problem at first on this mod. I have two questions for you. First, did you load the raduino firmware that ended with "_S", which denotes the sign

Thanks Vic. I am not the only one with this issue then. There have been a few other posts on this topic but no conclusions or solutions mentioned. I am trying different 2.8_E and 3.2_E firmware versio

Hi, I build my second uBITx now in v4 for digital modes only. After checking out the different s-meter solutions, I will go with the Raduino pin A7. Which voltage levels can be expected at VOL-H? Than

You could update the firmware, 1.1 is out. A few things. Are you using a Nextion, have you built the extra stuff necessary (ie, another arduino nano?). (I have a question about that, there's got to be

I was wondering how they simulated that old-timey glow. “VU Meter with back light by filament” It’s not simulated! Now if they would just heat distress the meter face it could be from a HT32. on order
