Reed, can you check the mic gain? There is as manual with the box. - f [email protected]> wrote:

Straight out of the box I hooked up to LiFePo battery and mag loop antenna. I can hear 20 m CW and sideband and get TX power out onCW but not seemingly on usb. I tried adjusting the drive and tried

It was great meeting you Pete, however briefly. - f

After a family emergency I made it to the Hamvention just long enough to unload mobility scooter meet up with Farhan and his wife Pick up my new sBITx radio Load up my scooter and head home to

Success with a 64GB card. I can assert that the software definitely loads on a Pi 3B+. At the moment I only have the Pi and display and no other hardware. The radio interface doesn't come up, but I

I have been checking for updates and doing the update build the recommended way from the original SD card I have (./update from inside sbitx folder). pi@sbitx : ~/sbitx

Congrats Salim. Do you have latest software build v2.1 from 11th May? -P #5

Farhan, So what is the power calibration procedure on a DE sBitx using this image file? There is no SWR bridge in mine or internal power meter, so whats the best way to calibrate. Joel N6ALT

I have been having a ton of QSOs on FT8 (and some on CW) ! #7 sBitx gives around 42W on 40m (after txcal) without any problems. Plenty of QSOs on all the bands from 80m and up (screenshot). 73 de

Great Listening to the W8BI talkin there was a stalled auto blocking traffic Once you get setup I will be back in today or tomorrow. Save me a sBITx money is burning hole in my pocket.:) I have a

Pete, Our crew was there but I was at FDIM. Now headed to the hamvention. Stuck in the long and winding traffic to Xenia...

I spent 8 hours at the Dayton Hamvention yesterday several times looking for Farhan. His booth is in building 5 #5304, but the space was empty. He mentioned in another post that he would be

Bob, 1. If you have a dummy load, attach it to the radio, 2. On sbitx, scroll down to open the console, in the console command line, type "txcal", wait for it to cycle through it for a minute or

Bob, Farhan and co. I think it would be wise to add a thermal mechanical switch to disconnect power from rig when the heat sink become too hot. This is the only way to prevent these blow

Farhan 1. Both, the sBITX and the external meter agree at about 22 watts 2. I tried to be clear that I abused the sBITX by repeatedly holding the key down while trying to record power and current

I installed a 2N7000 as you suggested. It has definitely got rid of the spurious RF on CW but I noticed that there is now some spurious RF at the beginning of transmission when on SSB. Not as bad as

Lou, check with the dealers as they may have just received another RPi shipment. I was able to purchase a spare today at a local dealer. -- Gyula HA3HZ

And that is exactly what you need to do with the BITX concept. Look at the circuit, think it over with your ideas (and what you have laying around) and modify the design. Just try out your thoughts,

Hello Ashhar, I quickly browsed through the bitx23 design. I really like that there is now a 2m transceiver design. I alsi like usage of a Pico as controller, as this is readily available and nowadays
