Ryan, Similar to the bitx40, one line to the radio with a regulator and a separate power line to the mosfets directly from the power supply. That way there is no need to modify the radio

Ron, Unless a reason comes up for not doing this in the meantime, I'll do it tonight and let you know. 73!

Anyone who can run a command-line on their zbitx want to try the following bash script to see if it improves keying latency: # isolates the sbitx process to CPU core 3 PID=`pidof sbitx` echo

What are the other connectors for? --Ed, N3CW--

Yup. ?I meant tinySA but typed nanoVNA. ?The boxes look too similar. ?73, Ron, n6ywu

First: sudo apt install cpuset Then, is anyone willing to try the following shell script to see if it improves keying latency: # # run sbitx process on CPU 3 and move all other processes to other

The voltage from that four cell LFP back is much too high for the sBitx. A three cell LFP would be a better option, though even that is a bit outside the specified 6-9V range when fully charged. Three

Jeff, I have a tiny drok in it now. ?3amp. ?It’s woking fine and cuts the current draw on receive in half. ?I didn’t notice any substantial increase in the noise floor. ?I do have an rf quite

Jody, I finally got around to changing my display name. The videos I shot for Iambic A were at 650 delay. However, I also toyed around with the the latency down to 200 still worked fine. I have been

SPLIT and RIT are not working with my zBITX.

I use them for my 12 volt radios. It would be nice if we cold find a 3cell LiFePo4 battery. LiFePo4 is safer and has a flatter discharge curve. Mike N2MS

I've been looking into building an RF quiet DC/DC converter for the zBitx. I've found some ICs that might fit the bill. But after April 5, not sure I would be able to make them at a price that

Gordon - Yes, I was just trying to suggest why we may all be reporting different results with my simple comparison test. santiagom5678 - your results are undeniably what I would like to get.? Have

Those are nice packs Mike, but they are 12V and would have to be Stepped down to make the zBitx happy at 8.4V. Joel N6ALT

I tried to activate SPLIT using the on-screen keypad (in CW). Neither pressing the button nor turning the VFO knob with the selected SPLIT button turned SPLIT ON. Did I forget to do something?

Hello Farhan My feedback on your question... Iambic A with a delay of 350 works for me safely up to 28 wpm, mistakes up to that and with higher speeds are mostly made by myself ;-) Straight key

Ryan, Looking at the schematic, what if you separate the 9v input for the finals drain and feed 14v to it. That way you can use just one 8v regulator to the rest of the system. Juan WP3DN

Wow!? I have certainly learned a LOT about the TinySA (I think ron meant this when he wrote "nanoVNA") in this discussion!? ?Joerg has apparently proven conclusively on his unit that there is an

Good question. ?I do not have a test & measurement lab; nor am I a qualified test & measurement technician. I know what those are, having worked up at HP Labs in the distant past, with access to

We should be looking at LiFePo4 packs: https://www.amazon.com/Talentcell-LiFePO4-Battery-Rechargeable-Phosphate/dp/B0DSW2S7YH/ Mike N2MS
