Reason is it may not be putting out 6W but far more.
I found no real correlation between front panel power setting and what came out.
The BIRD-43 wattmeter was indicating for 6W depending on band up to 30W!
Based on measurements I've made and the efficiency of the amps
72W in was likely around 15 to 25 watts out.
At highest power I've seen 63W before the current limit kicked in
at 10A (130W in at 13V).
It is also like many 100W radios at lower power setting the current needed for
low power is remarkably high.

SBitx: Red LED on microphone
I¡¯m using the microphone that came with my uBItx with my SBitx. The red LED is on all the time. Is that normal?

Hi Mark Yes i would like that... you can email vince320@...?when you get a chance. I've been struggling with my sBitx.. made some magic smoke for some reason... vince

I hooked my SBitx up to my current limited 12 V supply and at 5 watts output (confirmed on an external meter), the unit is drawing close to 6 amps. That¡¯s 72 watts input for 5 out. Is this normal? On receive, it¡¯s around 600 mA or about 7 watts, that¡¯s still 65 watts extra for 5 watts out.

Re: Sbitx #165 received today, thoughts.
Are you suggesting removing the paint on the exposed side of the panel with the countersink, or would it be sufficient to do it on the inside side, so you don¡¯t mar the appearance? I did a quick VOM check, and it looks like the connectors that the screws go into don¡¯t have good continuity on the surface (probably due to the anodized coating.

What IDE would you recommend for the RPi 4? FWIW, VSCode runs well on the 4, particularly if you replace the SD card with a USB SSD. I have figured out all the include paths and can use the code editor to jump around the source files. I just need to figure out the way to configure the compiling and linking.

Re: sBitx C403 Part details
UGG..
got a 50v...? ;=((
that's not going to fly long..
I would not run this at full power anyway, but again better to be safe than sorry..
I'll have to hunt up a 250 or 500 one.

Re: Sbitx #165 received today, thoughts.
Allison,
thanks for the feedback..I've had some issues, and I am sorting through them now..blew R403 and it burned the pad off on the Coil side...
as well as I think the T/R relay is welded to RX..more digging necessary.
a good BOM would be nice..(or maybe I haven't found one yet)

Re: N8ME_2_VU3GAO Firmware - Can it have same graphic style as the CEC firmware?
Ditto on Evan¡¯s warning about enlarging the holes carefully. If you look at the 2.8 Nextion you will see a small ribbon cable on one side. You want to work on enlarging the hole from the opposite side. I made the mistake of doing it from the same side as that ribbon cable and the drill/rasp slipped and cut that ribbon cable.?

Re: Gtk-WARNING: cannot open display (./sbitx)
Could you do:
ps aux|grep X ps aux|grep lx
(That second line is grep lima x-ray¡.)
I¡¯m curious to see what the command line is for the Xorg process, and is user pi owns the various lx* processes...

Great response. So I could go with Nextion / CEC on Ubitx V6? Scrolling posts couldn't get a super clear answer as to if it's supported.
Curt, Here is a link with the details on how to do the 2.8" Nextion conversion of a v6: One point, with careful file work on the Nextion display, you can get the display to fit the holes of the case. 73 Evan AC9TU

Re: Gtk-WARNING: cannot open display (./sbitx)
Are you trying to run sBitx from another computer in a remoteterminal (like Putty)? Not possible.
You need a remote desktop or vnc or ...?

Did you do a ./build again after fixing permissions?

Rolf , maybe that's what I saw too.. just a picky decoder for cw... but just could not get it to work... tried several signals...?

Re: Gtk-WARNING: cannot open display (./sbitx)
I see a problem. ?The directory and all the files in it are owned by root. ?You are user pi.
This should fix that:
cd ~? chown pi:pi ./sbitx cd ./sbitx chown -R pi:pi ./*?
( I¡¯m always hesitant to do a recursive action like the one on that last line, but it should stay within the ~/sbitx directory and not hop out of there¡. )
