Hi Ashhar and all, What does it mean this part of the code of the ATtiny85, I don't get it: -- ? if(flag == 1){ ??? digitalWrite(5, LOW); ??? flag = 0; ? } ? else { ??? digitalWrite(5,

If you don't want to use Raj option, other option is to use the ATTiny85 port 6 in order to have independent control (just send the info to the ATTiny85 via i2c). Rafael

I just discovered a kink in spectrum_update that was eating up the cpu. I will push out the changes to idle the cpu back to 40% on sbitx. - f wrote:

Take the 12V from R10 upper side and feed to a 12V relay. Use the relay contacts as you want. The relay will isolate sBitx from your circuit. Raj

Farhan I am not sure about USB spec. The keyline output should go low during transmit to be used for transmit/receive switching of linear amplifiers and transverters. For keyline voltage and current

It is best not to tap this off the raspberry pi line. Perhaps, we can use the usb port to signal this? - f

We were ready to ship on monday. There were a few paperwork delays. We should ship in the next 24 hours. - f

Thanks for the detailed information. I know that the solution is always in the details. I noticed that the heat generating components are well placed on the SbitX v2 pcb. It is still hard for me to

Farhan nice. Thanks you for info. There is no rush. It is better to do everything calmly and correctly before shipping and not rush it. - P

Yes, they are numbered. They will be shipped in 24 hours.

On the sbitx v2, we have ample air vents on the top of the raspberry pi as well as on the side panels. I have busted tens of raspberry pi boards but none from too much heating. The raspberry pi draws

I have a non-technical question.?I am not sure how it was with V1 DE but will the V2 units be numbered (sn)? - P

Yes Farhan, ptt out would be important feature as the output power of V2 seems to be enough to exciting standard amps. - P

PTT is usually an input to signal that the operator wants to transmit. Do you want an output to control a linear amplifier? [email protected]> wrote:

As Ashhar pointed out on another thread regarding a T8 failure, the real question is, why did it fail? So after repairing T8 I did some testing. First, power output on all bands was low—about 1 watt

Does the subitx have the possibility of a PTT (one contact output)?

I should have stated that the Sbitx running is a v1 DE that was updated to the v2 software.? There could be an issue with the update.? When the iso for the v2 software is available, I will re-run

Here are screenshots of loading using htop with the temp monitor enabled in the taskbar. With the Chrome controls on: With Chrome off: Memory usage never requires swap space, so there is no memory

The memory footprint of the sbitx is tiny compared to the gigabytes of ram available. I guess the chrome eats far more RAM than the sbitx does. It works even with the tiny raspberry pi zero
