Hi Bruce. With a little more thought on my end, what is the Bandwidth of your scope and probes? For example, a 100 MHz scope with 300 MHz probes has a combined BW of ~94.868 MHz. This would be <3%

Hi Ford, Did you follow the procedure in this video? https://www.youtube.com/watch?v=t6LGXhS4_O8 You should note that the original software loaded in the uBitx from the factory offsets the

I have 4 pins in the socket. The half-cut holes are not contacts, check the pcb. -- Gyula HA3HZ

That's not the question. The question is: in the upper 4 or the lower 4 of the 5 pins of the socket?

Farhan sent me a uBitx about a year ago.? Mostly assembled and the final assembly went without a hitch.? Very nicely done!? Seemed to tune the bands.? Put out RF as expected.? Drew about the

Richard, I haven't had a qso with qsstv though the interface has been done and desk to desk testing has also been done. We are shipping with Raspberry OS Buster. - f

Hi Just wondering does qsstv interface ok with the sBitx ?. Also is the supplied raspberry pi os the current one or an old one Regards Richard G7OED

Just got my sBitx v2, and took courage to open it up. I was going to put in the CR2032 coin battery into the real time clock, per various messages I saw. To my surprise, it was already installed.

Farhan, I was able to correct the power levels for 80 and 40 meters.? I could not get to 20 watts on 12 or 10 meters. To reduce the number of times I needed to restart the sbitx program, I created

In case it wasn't obvious, there was a typo. The second range should have been V3 and V4 and *NOT* V3,V4,V5 as stated above. 73 Mark -- AJ6CU KD8CEC 2.0, Nextion Screens,? and open source uBITX

Open a terminal and do a sudo nano ~/sbitx/data/hw_settings.ini edit. Play with the “scale” coefficient up or down 20% and save. Restart the sbitx process. Start at Drive=50 and increase to 100 if

Evan, You will have to hand edit the hw_settings.ini. open it in a text editor and reduce the scale settings for 3.5 mhz by about 20%. Save the ini file and restart sbitx. See if the output power is

Hi, 2019 I got the V5 uBITX - Suddently made enhancements - nextion Display - CEC Firmware - AGC, Audio CW Filter - Audio Amplifier, AUX connection for FLDigi waterfal Try now to make a new

cloyesjn, What software are you using?? Vic pointed out that the 4.3 version of the HFSignals code changed to transmitting a 10MHz signal when put into calibration mode.? That is not the case for

Where do you set the power levels for each band on a V1 DE running V2 software?? I have tried the default_hw_settings.ini and the hw_settings.ini files, and neither affects the power output.? I also

When i push the momentary switch, the TX light goes on and stays on until I exit the menu system and I hear a relay engage?? Would a relay engage on a final oscillation? .? I tried the dummy load

If you’ll give me your call sign I’ll check it out. 73

Thanks. I don't use my scope much anymore so it's time to blow the dust off it.
