Bill, I'm not sure whats going on. I noticed you have SN 0045, mine was a V2 radio also, SN 0042 so built at the same time yours was and my new V3 board just dropped in very easy. Maybe the heat ink

AND? what is the purpose of the 2 screws on the "new flange" on the back of the heatsink ,? screws facing out ???? looks like a hacksaw ,,,,,coming soon???? how appropriate HACKsaw.

I GOT THE v3.02 ? BOARD KIT TODAY. The V# board heat sink is offset from the enclosure cutout .... OOPS /// do I need to take off the outputs,,, and take the sink off and mount the sink from the

That was a very informative video. I'm primed to try some ugly construction for the first time (more or less) since I build the Ugly Weekender back around 1999. I wonder if anyone happens to have the

Sure Gyula, ? original finals in the V2 were an issue. ?Had an initial failure running FT-8 on 10m at about 50% power. ? At the time the power supply was a 30A non current limited unit. ?I

Michael, could you tell the forum readers why the final stage fets had to be replaced 4 times? What antenna, what power supply did you use and in what modes did you use the device so that this could

I replaced my V2 with a V3 board.?? Moved the Pi4 over and used the new SD card.? Works great except for the V3 SWR not really reading.? I replaced the finals ( 4th time ) in my old V2 board with

Thanks Evan. I'll keep working at it! -- Mike KB2ML

Hello Mike. There is an error in the final formula. The correct formula is New Scale = Current Scale * (power setting/100 * desired max power)/Measured power formula Sorry for the error in copying

Evan, I decided to try to level the max power output on my sbitxDE by adjusting the values in hw_settings.ini. I followed your example and built a spreadsheet. Following your example calculations I

hey Charudatt, I have clean simple 6 meter code you might want to look at... writen on the raspi pico and a sh1107 1.3 oled.? it has alot to it . contact me a n4cnr.ham@... I figure if we

Hey Bill, One other thing I forgot to mention, you will have to move your Raspberry Pi over from the V2 board to the V3 board but that's easy, just four screws, also make sure to install the SD card

tnx Joel , that sound like my plan... ? ? what are the specs on the diodes used for clamping..???? -- link to my QRZ listing https://www.qrz.com/db/ny9h

Hi Bill, To answer your question, just take the V2 board out and install the V3 board in it's place. They are basically identical boards, the V3 board having IRF510s for finals instead of the

Gyula, good catch! I do have XT65s, I've just labeled them incorrectly in the schematic. But you are right in that I have them flipped, that's a quick fix.

expecting a board ( to get current ) ..... got tired of having to pay attention to all the conversations on mods.... guess I'm 50% appliance operator & DXer. so you have any hints? , should be

It would be interesting to incorporate a small UHF antenna directly into the sBitx, when and if it will support the band. With a dedicated antenna socket, it could offer "off band" communications to

sorry if already suggested, I guess I should have read the previous threads before...

Well, you just need four contacts, but I see your point.
