Tom, I've sent you an email.? I'm responding here so other people don't argue with my place in line. Cheers, Harris Butler, NN0Y

That was quick! Gordon

Sold.? Thank you.

May i ask what resolved the low output on 20m what was it before and where is it now. Mine is also sluggish there at 13 watts while 40 is 22 watts. I expect it to be lower but? Thank you -- Patrick

Selling my sBitx V2 serial no. 0251. I assembled it, made a few ft8 and cw contacts, updated to 64-bit, #D printed a cover that allows for connection of mini HDMI cable to PI for extended display.

Absolutely! I definitely am down for a kit. I'll reach out Thurs. I'm glad you caught me on this. I love Farhans ideas, But like you mentioned, it makes no sense to me why you wouldn't go the route of

Well thats the very reason i designed that little gem. It works without gain sag to 54 MHz… and you can short out or open the output 24/7 with no issues other than generating some heat. I gave

The diode solution won’t make any noise either! Those switching systems might make noise!!

Simpler and less efficient was would be to solder some 6A10 rectifier diodes in series till you get the voltage down to what you need. I have used this in the past and it works. I am sure there are

Yes, I understand trying to keep the cost of components down, but after further research, and my own experiences with a few bitx products, why keep chasing down a design around a MOSFET not intended

Amazon and AliExpress sell sealed buck boost regulators from 3 Amps to 30 Amps from about $5 to $50. They are pretty much bulletproof. Output voltage is chosen by the unit selected and input is from

You might want to look at some of the DROK buck converters.? I think they have one that will do what you want, & they are very power efficient. Gerry Sherman Sent by the Windows 11 Thunderbird

I think you'd be best served by using a regulator to turn 13.8v into 9v, rather than trying to redesign the radio to natively run on 13.8v. I imagine a suitable circuit could be installed in the 18650

Hello, we haven't received any zBitx yet and I'm already thinking about modifying something. I don't really like the fact that it goes to a maximum of 9v, and I would like to know how to modify the

Okay, I'm interested. Where is the site to order from? -- Mike - K8MCB

This the complete Sbitx as built, the only 2 changes are the upgrade of the Raspberry Pi 4 from 2GB memory to 4 GB memory and the master board was upgraded to a newer model to resolve the low power

Hi Tom, Is the case included?? Any other items that are included, like the mic and display? 73 Evan AC9TU

Hello! while waiting for my zbitx to arrive, and after reading the sbitx manual, I can’t find a reference on how to use a manual tuner in order to keep the finals safe. I have a Chinese zmatch qrp

Here's a link to the discussion: https://discord.com/channels/1026361918505635890/1333220374376353893 It's a very simple mod. You'll need to print the holder and some jumper wires to go to the RTC
