Morning all, N4CNR (Rich) Thought I would give you a update on the new code and changes. I moved to a xiao-esp32-c3 board and a pcf8575 i2c io board , also added eeprom for saving changes, code for

Hi David, Are the stl files available for your build? I'd like to try to give it a go. 73 Jason KB2SDR

Hello, I have also problems, fwd is on pin 3 and refl on 2 I adjusted in the sketch but no result alway 0w and swr 1. During transmit I have activity on I2c and of course I triple checked for not

Hi Dean Yeah, you did a great?job with your build - very impressive. I have been following your project with great interest - here and on Soldersmoke. This is the first version of the PCB. There

Might look at what Sunil has.? Don't know if he has anything, but it doesn't cost anything to look. Gerry Sherman Sent by the Windows 11 Thunderbird

I have a uBITX v6.? I'm wondering if there is a much better looking case to replace the rather ugly black OEM case.? Anyone know of one I can put my v6 into?? Thanks, Richard AG5M

Dean, It great work also. Like the modular aproach. In my build Im using just one rd15 driven by a single 5109. It works well but runs a little lower on 6m. So may split the driver into 2 sections

Dean, Stupid question, Do you have a complete writeup or hints for the homebrewer on this homebuilt SBITX? like which outlets to source the parts,crystals,etc? 73 David ac9xh

Ian - That's beautiful work - and much prettier than my board!? BZ! and wWelcome to the happy few homebrew sBitx builders club.? And you win the prize by taking the software on as well. I'm

Heard that VU2EVQ linear amplifier was made specifically for BITX working on 40m. There are several hams in my region using it along with BITX, with good signals on 40m. Unfortunately, it is no

i will stick with the ubitx. low cost proven, and easy to repair.Also the bitx40. As for microphones, i just open both ends, grab some paper, ohm both ends out. if the radio requires an electret mic

yea, the bitx is easy to repair, its low on current draw and easy to mod for USB ,Digital display if wanted and adding CW. Too bad, we need simpler kits like the bitx to occupy the low income hams who

Two things that attracts me to ubitx. First Farhan's excellent openness with this radio, which is unmatched. If you want to learn how a communication receiver works internally then ubitx has its

Yes, there are TVS diodes installed on both the V3.01 and the V3.02 boards. Joel N6ALT

Wonderful design, nice work, congratulations. -- Gyula HA3HZ

And I also have a related question. Would simple zener diodes work on the gates? Or are they too leaky? Well, I guess that is two questions... lol. David [email protected]> wrote:

Does the board include gate protection on the final MOSFETs?

Great work!!! It sounds fantanstic!! Juan

Hi Everyone This is my version of the sBITX. It uses a Pi Pico 2 rather?than a raspberry Pi. It does not have all the software capabilities of the sBITX but it does have a spectrum display. I

Seems there are quite a lot of VUs using BITX! Even today evening I worked one of them on 40m SSB. Enjoying the discussion and learning a lot about BITX architecture in the process. Maybe someday I
