I correct the errors in the database, because the font size of the 7" screen is small. Therefore, when I want to correct it, I copy the sbitx.db file to a USB stick. Then I installed the DB Browser

Several things... One IRF510 spec is 100V breakdown.? More than that and poof. Also sustained current should be 4A or less (the 5.6A is for saturated switch mode). So the question is why it it 100V

Hello All, ? ? I hardly see any power out on transmit on SSB on any band. I can hear the relay click when I press the PTT button and speak into the mic and I see TX on the display but no forward

Joel, The all the IRF series exhibit this behavior. Just monitor the RF Output over 1 minute of key down. wrote:

Can you explain what the bug is between the keyboard and the logger?

Thank you Gyula and Evan, The cookbook works, and in minutes I was up running v3. i even logged one ft8 connection. Now I look forward to learning v3 features. whising you both a good WE 73

Thanks for the fix. now it's fine and doesn't want to switch on. Question: is the log keyboard still not working? I would like to fix it, because it sometimes saves data incorrectly. -- Gyula HA3HZ

Farhan, I know you have always preferred the IRF510s, but have you considered the IRF530s? I have noticed that most of the cheap Chinese Linear amps use them to get a good 45-50 watts. I just bought

Quick question about the transistor choice. Could you also use IRF520 transistors as well as the 510s? I am wondering as I have some 520s left over from another project. WK4DS

I have observed that any linear amplifier when operated on keydown for more than a few seconds starts to reduce the output power gradually. My sbitx v3 amplifier is using IRF510s. The output power

Gyula, This is fixed in the eeddbae (last commit). Run update to get the fixed version - f

Hi Harold, I followed Gyula's process using the Raspberry Pi clone SD card in the accessories program list to a USB-connected ?SD card reader/writer.? I have a DE, so getting to the ?SD card is

Hi Gyula, Thanks for the description. When you clone the uSD card do you move it to a PC or do you do it while it is in th sbitx? 73 Harald

Guyla, I had that happen to me too.? I've noticed a few quirky things but I think most of them are from my arthritic fingers hitting the wrong position on the touch display.? I need to find a nice

*Sbitx v2 to v3 upgrade* *Cloning from github* First I made a full uSD Copy from the working sbitx v2 uSD card. (so that in the event of a malfunction, I have a working system from which I can

Hi Bob, I have fully modified DE less the SWR/Power sensor.? The V3 software works very well for me.? The process I followed was to rename the current sbitx directory, clone the repository, then

Let us know if this works? -- Bob AA4FJ

I have not installed the sensor. It is just a fully updated DE. Will v3 work if I install it? -- Bob AA4FJ

I am excited to test V3 asp. i hope you post a detailed cookbook for those of us who need some handholding.
