I saw a post in the past year about the construction of this transformer but I can’t find it. Does anybody have a link to ?it? I might find new toroids but I don’t know what mix to get.

Also, there were two separate episodes, a few weeks back, where the power output shot up for at least a few seconds, spontaneously, to 69 and 77 watts. I don’t know why that happened, but perhaps

Hello Gyula, Do write to sales@... regarding your order and we will do the needful. Thanks, Thomas

The same thing happen to my unit. Two toroids on one side broke off. It was happen during adjusting the drive current. I think it was a from of ps motor boating. There was a buzz coming from the unit

Hello Gyula, Please write to sales@... regarding order related queries. We haven't received any mail from you at Support so far. Thanks Thomas

I would like to change my order before it is shipped. But I don't get any answer. -- Gyula HA3HZ

I must be living under a black cloud. After getting the rig up and running I found that the PA output transformer had three of the ferrite toroidal cores cracked. I assume it overheated, possibly when

Ordered a sBitX V2 without RaspPi yesterday (12 April). I have a 4-gig Pi 4. Any tricks to putting it all together? I have and use multiple Pis, Linux is my main OS, I have 40m and multi-band BitXs,

I sent PM to Thomas regarding #2093 too. Maybe overloaded so do not want to bother. - P

Ray, Not yet. We have a facility to switch four LPFs. I understand that mars et al work around 5 MHz, whereas the current circuit is optimized to work only on harmonically related frequencies. While

Yes, clearly the Raspberry Pi is the master. On boot to the desktop CLK1 is quiet, but starts up instantly when the sbitx process is initiated. When the sbitx process is terminated and I’m back to

Yes, it has a full hang agc with three settings fast/med/slow. The earlier version had the option of setting attack, threshold and decay but I thought it was an overkill so we have just three easy to

You can loop the code in the sbitx.c that calls the si5351 over and over again and put a break point to see what is happening in the i2bb.c file - f

Does the sBitx have automatic gain control? SM6MOJ

I think it just didnt work and I moved on. I remember the spectrum flat lining.. but that was all. - f

Yes, that's correct. You have to start the terminal window all over for it to take effect. I am not sure if it is relevant or not, but I had added this as the last line, not the first. wrote:

Perhaps I edited the file wrong.? When I edited the .bashrc, I simply added the line: export DISPLAY=:0 as the first executable line.? Was that correct?

Jack, The Raspberry Pi is the master.? I suspect that the bit-banged code does not have all the error handling that the OS-based code does.? This is just a guess. The next step for me is to see if I
