Try changing the diodes first. Be sure to use 1n4007s from Mouser ir Digikey only. The others don't work as expected.

Yes, it should only some up if you go to a really really low frequency like 500 kHz

Jack I am unsure that the in-circuit capacitance should sum up with the inductors between the capacitors.? Could this point to a short in one of the toroids?? It may be a good idea to pull the

1. Have you looked at the waveform going into the low pass filter to be sure that it actually looks like the right frequency? Is there a possibility that you have more second harmonic then

Steve -- OK, so quick easy workaround until there is a fix. Plugged in a set of headphones. Problem temporarily solved, everyone in the house is much happier. 73 Roy

2021, 2022: enormous effort was required to even FIND a raspberry pi. You could expect to spend well over $100, you might have to pay 170 and buy a complete starter set up to get one… For

I've read that sidetone suggestion. Unfortunately I have CW sidetone at 5, sbitx volume at 40, and set desktop volume to 16. What happens (additional info) is as soon as the FT8 TX starts, the

Jack - is anything in that LPF getting hot when you transmit?? If there's a short, that RF power may heating the shorted device up. 73 and HNY; Steve, N3SB

FYI - there are two versions of sbitx.c - the first one includes Gordon KX4Z's mod to eliminate LPF relay chattering during CW transmit on the DE. The second version is more appropriate for those with

I checked voltages on 17 meters along different points of the LPF chains first through LPF_A and then through LPF_B (the one that seems malfunctioning). CW, Drive=100 LPF_A???????

Hi Roy; Right now the way to turn down the FT8 monitor volume during transmit is to change the mode to CW and turn down the sidetone level, then go back to FT8. 73 and HNY; Steve, N3SB

I have been following the audio thread over the last days, so hopefully someone will have a suggestion for my problems. When using FT8, the transmit volume is reset to 76 (as seen on the desktop

I just submitted a pull request to the afarhan/sbitx github to implement an automatic IF Gain control. The changes are all in sbitx.c. This change will hopefully make it no longer necessary to change

Dave - very interesting! Glad you are poking more in this area. At some point we may want to send sound to some other device, which will probably require reclocking. This could be why the V2 web

Gordon, The added Q is on the back of the board for the DE units. -- Allison ------------------ Please use the forum, offline and private will go to bit bucket.

the easy fix for the 2n7000 is add a small (1/8th watt) resistor in series with the Drain.? 100 ohms will certainly be enough. -- Allison ------------------ Please use the forum, offline and private

GOOD NEWS!!? ?The sBitx Lives Again! Allison -- It was 250mA combined; I had previously set it at 360mA combined trying to improve the horrible spurs, which turned out to be due to shorted diodes
