Latest T41 source code release
All:
I know there is cross-platform interest in the T41 and the latest release of its source code is now available on the SoftwareControlledHamRadio web site.

Win 11, CH340 driver's advanced port setting require setting changes to work with Nano. FYI, I just changed over to new laptop with Win 11 and needed to program a Nano. I could get the board info (as much as normal with a clone) via Tools-> Get Board Info? Device Manger -> Ports(COM &LP) showed USB-SERIAL CH340 (COM8) So all seemed OK :) But when trying to Upload a sketch, I got this error:
avrdude: ser_open(): can't set com-state for "\\.\COM8"
digging into the driver settings
Device Manger -> Ports(COM &LP)? -> USB-SERIAL CH340 (COM8) -> Properties -> Port Settings -> Advanced...
Clicked the checkbox "Enabling the Serial Port Enumerator (SerEnum)"
Now I can program the Nano.
I don't remember having to do this with Win 10 (older driver) and don't have that machine to check my sanity.
Wanted to pass this along to anyone who is having this problem, or a problem in the future with machine/OS/driver updates.
I don't need help.? All is working fine.
Rgds,
Gary

Re: IW2NDH Panadapter Kit for uBitx
Mark, The Panadapter Board with the I-F Buffer Board was $90.00 plus $7.00 Shipping. You also need the ILI9341 SPI Display which you need to purchase from Amazon, Ali Express, or other supplier $11.00 to $15.00 depending on supplier. The display price was for the 3.2" display. The I-F Buffer Board which measures 1.18" x .58" (30mm x 15mm) excluding the Female SMA connector is mounted inside the radio with 3 wires. Then a coax cable connects the I-F Buffer to the Panadapter. It's that simple no RF Switch or anything else. Here is the connections to the uBitx. Hope this helps.

Re: Sbitx V2 low power on only ONE band--why?
Rafael, I already tried to increase power by editing hw_settings.ini and 3W is the max on 17 meters. It used to be 15-20 watts or more (I can check my notes but it¡¯s true). Again, I think there must be a hardware problem that is new.

Device i2c address 0x57 and 0x5f?
Is anyone else seeing devices with addresses 0x57 and 0x5f in the i2c bitbanged bus? What are them?
0x60 is the Si5351
0x08 is the power bridge (Attiny)
0x68 is the RTC
I still see addressed 0x57 and 0x5f listed by i2cdetect.

Re: RS-HFIQ and Raspberry Pi
Thanks?for that update, Shirley.? I did have a pi-sdr from SV1EIA but sold it along with the UHFSDR I built years ago. Now R Pi 4's are available, I was hoping I might be able to put something together myself with a low cost codec breakout board to go with the RS-HFIQ, since all the software now seems to have been created?to make a standalone everything box!

Or perhaps he will update the board to include a second audio I/O for that.

I am excited to see all the effort that has gone into the R Pi code with the sBitx, so it would transform the RS-HFIQ tx/rx if it could be driven in the same way. It looks like we just need a decent codec for the R Pi. Has anyone done this already?

Re: Sbitx V2 low power on only ONE band--why?
There are too many power gain differences across the bands. Currently there are 8 bands/gains defined. Play with the gains first is my suggestion. This is normal afaik.

My V2 is working well but I can only get 3 watts out on 17 meters.
All other bands have higher power. I've done the latest ./update
of the software and also the txcal command. I have adjusted the
scale coefficients on all bands to have no more than 25 watts out
on CW to be conservative. Despite increasing the scale coefficient
for 17 meters it tops out at 3 watts. This is into a dummy load. I
have even tried a new sd card image and there's no difference.
Here are the power outputs (Drive = 100, with hw_settings.ini
scales adjusted, and on 10, 12 and 17 M maxed out):
10 M???? 10 Watts
12 M???? 13 W
15 M???? 25 W
17 M?????? 3 W
20 M????? 24 W
30 M????? 25 W
40 M????? 24 W
80 M??? ? 22 W
I would think it might be a PA transistor or driver problem but
why would it be on one band only? And I used to get much more
power out on 17 meters. Again it doesn't seem to be a software
problem because I even swapped out sd cards to run a different
image from a file saved that worked before. Could it have
something to do with the LPF circuits? But 17M doesn't have its
own dedicated LPF line and all other bands work.
Suggestions?

Re: IW2NDH Panadapter Kit for uBitx
Sam,
Perhaps I misssed it, but didn't see any pricing on the website. Out of curiosity, can you share in round numbers what this costs? So this hooks into the IF and does not need a RF switch like the MFJ 1708? (and clones).

Sbitx boot stalled by wireless keyboard dongle
Here¡¯s something that caused me a lot of trouble and time to figure out. If it happened to me it might happen to others. It has to do with a ¡°bad¡± dongle for a wireless keyboard.?
It¡¯s isolated to one dongle, and that dongle used to work flawlessly. I have a separate dongle/keyboard pair, and that other dongle works fine. Furthermore the bad dongle causes problems only with my sbitx-DE and not with my sbitx V2, so the incompatibility may be also related to using different Raspberry Pis. It took me hours to work this out. What a headache!
The DE wouldn¡¯t boot. The 7 inch screen stayed completely dark. Furthermore the green LED stayed on continuously, suggesting a problem with the boit process. I tried switching ribbon CSI cables, different sd cards, even switching Raspberry Pis. Finally I removed the wireless dongle and the unit booted with a good 7 inch screen display.?
i connected an external monitor through the HDMI port on the Raspberry Pi and got a boot error message screen. Please see the screenshot/photo. This is with the ¡°bad¡± dongle inserted before attempting a bootup. I hope someone familiar with these boot error messages can let me know whether the messages explain what¡¯s happening. Again, this was during a failed boot attempt with the ¡°bad¡± dongle where   the 7 inch screen remains dark.
The DE boots up perfectly when the other dongle is inserted before bootup. Furthermore the ¡°bad¡± dongle does not prevent the V2 from booting. What¡¯s even stranger is that when the DE is booted without a dongle, if the ¡°bad¡± dongle is inserted after a proper boot the dongle/keyboard works perfectly. That¡¯s why I call it a ¡°bad¡± dongle, in quotes. The DE, but not the V2, can¡¯t boot properly only when the ¡°bad¡± dongle is inserted before boot, and not the other dongle, but the ¡°bad¡± dongle functions well if inserted after the DE boot sequence has finished. Confusing, isn¡¯t it?
This has been an enormous time sink. If you find that you get a completely black 7 inch screen during Raspberry Pi bootup and have one of these little dongles inserted in a USB port, first try rebooting with the dongle removed.
Does anyone have any suggestions regarding what¡¯s going on?
Thanks,
Jack, N6LN

Re: File /uBITX_6_N8ME_2_VU3GAO_Mods.zip uploaded
#file-notice
Hi David,? I'm not sure I understand your question.? I've not tried the N8ME software on my V6.? I use my own version of the stock software that fixes some of the issues I found.? I did make some changes to the alignment code that allows finer adjustment of the frequency, and allows a screen touch to save the tuning values (instead of a button press, that seems to easy to change the value while pressing).? My version is found here if you want to check it out:?? .

Rolan,
Since you created this, have you had a chance to test the ubitx out on the ubitx alignment?
Seems like it might make it easier to align the frequency of it and also easier to zero beat.
have you tried this ? Just asking.I own 4 ubitxes v6
Thanks for your Work, Rolan.
