Hi John, The v4, v5, and v6 boards have M3 holes.? I do not have a v3, so can not measure the holes on that board. 73 Evan AC9TU

Yes M3 as I remember - 3mm metric.

Hi Ashar It was fun to see you updating when I was reading the FT8 section :-) When can we see the full schematic of the transceiver? Is the second mixer a? 3157? in the end product or is it a diode

Really nice looking, full-featured, rig! Jack, W8TEE

I have tried some different standoffs but the pc board hole is smaller than what I have (6-32). Are they M3? 73s John N4HNO

I am impatiently waiting for the new schematic!!! Almost ready to start, all components on my table. It will be a great small rtx. Paolo

The manual looks good Ashhar, I guess people will be able to make additional contributions once they start playing with the device, whilst we are on the subject it would be really good if we could get

I had a problem on a well-matched 40m end-fed -half-wave portable antenna. Only on 40m the uBitX radio running CEC software would go into menu mode when transmitting. Adding a 10 ft counterpoise to

Thanks a lot Farhan! Can't wait to put my hands in a sBitx! : ) Cheers, Rafael

Tim: There are those who have even installed 0.01 MFD capasitor from each side of the mic connector to ground. Dave WD8AJQ Sent from my iPhoneSE

People, I am writing a short manual for the sbitx. I just started it but in the spirit of "Share early, share frequently", I am editing it online on google docs. You can follow my progress at

Tim Possibly if it's a very short feed to the efhw that could be the issue. The ubitx can be more sensitive than many rigs. So try various things, including earth connection if it can be short

Hi, Ashok Here is something to get you started. https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/picosynthrf---a-python-based-rf-signal-generator /Best Regards

Tim, Yes, on the coax.? Where to place the ferrite on the coax depends on whether you have a tuner connected to the antenna.? Then the ferrite needs to be after the tuner.? If it is a resonate

Thanks for the input Evan, do you put the ferrites on the coax? In this case my antenna is an end fed dipole. Tim N7LVB

Tim, I had that issue with my v4 uBitx connected to an Off Center Fed Dipole (OCFD).? The problem is RF getting into the Nano.? It is made worse by an SWR mismatch but is still there if there is any

Hi Ashok, I use the N8ME with the VU3GAP mods.? It is the one that I recommend for the v6 uBitx. /g/BITX20/files/uBITX_6_N8ME_2_VU3GAO_Mods.zip As Gary said, multiple updates can be

My antenna is tuned to a 1.2:1 SWR match. When I key down and try to talk the radio opens the menu and spazzes out. I’m running KD8CEC firmware and a nextion 2.8 display on a ubitx v6

Welcome Ashok, That's an artifact of the momentum code, settings for the encoder in the factory firmware. Folks have enhanced the firmware for the Nano to overcome some of the operational shortcomings
