After so much frustration with the sBitx v3? I finally installed your 64bit version of the software. it went like a breeze, installed it on a 64GB SD
card and voila. Finally I can enjoy the radio.
Even the audio transmit is now clear with enough highs. My last problem is that I can only get about 2 watts out in SSB,
Thank you for an outstanding work.

Hi JJ, Thank you for the response.? I noted that line (it is 58 in the version I looked at from my V3) and also found line 898:
static int hw_settings_handler(void* user, const char* section,?
? ? ? ? ? ? const char* name, const char* value)
{
? char cmd[1000];
? char new_value[200];
?
?
if (!strcmp(name, "f_start"))
band_power[hw_init_index].f_start = atoi(value);
if (!strcmp(name, "f_stop"))
band_power[hw_init_index].f_stop = atoi(value);
if (!strcmp(name, "scale"))
band_power[hw_init_index++].scale = atof(value);
?
if (!strcmp(name, "bfo_freq"))
bfo_freq = atoi(value);
}
I assumed that the value was the default and would be updated if the bfo_freq was found in the ini file.? However, the code may be orphaned and not being used.

Hi Evan
I tested this earlier in the week by making changes to the frequency and did not see any measurable change. The reason may be that it is in sbix.c on line 69
int bfo_freq = 40035000;
-JJ
|
Has anyone investigated the impact of changing the BFO values in the hw_settings.ini file?? Are all set to?bfo_freq=40035000?? Could this value be used to fine-tune the frequency accuracy of the sbitx?
I have limited access to my sbitx due to medical issues, so have not been able to test for myself.

Hi.
I did some research on the requests and don't think the masses will find this useful as part of the Toolbox. The Toolbox is designed for a functional radio as icing on the cake.
Explanation 1. The TXCO clock frequency requires a change to si5351v2.c and then the system must be recompiled using ./build sbitx. You can simply adjust the clock frequency in the file and test with lab equipment.
Line 44-46 is where to make the changes.
#define PLLFREQ (xtal_freq_calibrated * PLL_N)
//int xtal_freq_calibrated = 25012725; // crystal oscillator?
int xtal_freq_calibrated = 25000000; // tcxo
Explanation 2. The ATTiny module can be stripped out of the code, but you will require changes to many files. it is best to do this on your own for a customized build.
Sorry - My efforts are focused on improvements to other enhancements and features at this time.

Re: uBitx V6 with Nextion display
What is strange is there is another guy on the uBitxV6 Facebook group I am a part of, and he just install a Nextion as well.? He is having the same issue.? CW fine but no SSB.? He has?so far checked voltages of all transistors and FETs they are good.? A really odd one

Re: uBitx V6 with Nextion display
I was going into a power meter then to a dummy load.? ?I just tried it in CW mode and it works at full power.? Do I need to go into BFO mode on the menu and change something so SSB works?

Re: Easy way to access the WEB GUI from anywhere in the world.
Here are a few other options that require no ports to be open. These are very easy to setup and there are lots of YouTube videos.?

Option 1

Option 2?
You can install a client on rip or setup what is called an exit node to route to any device on your network. Exit nodes can run on lots of different devices and does not require very much compute or memory.?
Here is a quick setup video for Tailscale.?

Re: uBitx V6 with Nextion display
N4GW,
What mode and how are you measuring the power?
I start with CW, verify that the signal gets to Q90, and trace it from there.? CW eliminates calibration issues as the BFO and other mixers are unused.? The first mixer is unbalanced, and the Si5351 sends the actual transmission frequency.? If you have an oscilloscope, you can verify the signal at TP12, TP2, TP3, and so on to the finals.
Does the radio still receive?? There have been instances where the Si5351 on the Raduino was damaged during the KD8CEC installation.

Re: Easy way to access the WEB GUI from anywhere in the world.
IF you can forward the ports in your router and keep track of your IP that is definitely the way to go.? ?I've done that for years.? That's assuming your internet provider isn't blocking incoming ports.? For some folks forwarding ports can be complicated.

Hi, installed the Nextion display and it looks real nice, but I I now no longer have any power out on transmit.? Anyone know what to do to troubleshoot this?

Re: Easy way to access the WEB GUI from anywhere in the world.
Another option that I'm currently using, duckdns.? Go to duckdns.org, sign up for an account.? Make a domain name, it will be XXX.duckdns.org.? That will give you a key.? The website then has really good instructions on how to copy a bit of code and run it
as a cron job.? It updates the duckdns servers of your current IP so that your domain is always pointed to the right IP address.? You'll need to go into your router settings and allow port forwarding.? I have 2 rpis setup like this, so I have to set the sbitx
to route from port 8090 while the other device is on port 8080.? The routing table then sends the 8090 requests to 8080 on the sbitx.? I'm running FT8 right now while I'm at work using my phone as a hotspot to a tablet.? I'd have to change a couple settings
in my port forwarding to allow realVNC, which I need to do so I can use jtdx and other programs.?
I'll have to check out Pinggy and see how it compares, in my case it should be pretty much the same.? For others with trickier port forwarding issues, Pinggy will be the way to go.

One way to access this radio remotely is utilize port forwarding through your router.? But many ISP's and routers by default block this traffic.? It's just not as easy to forward ports as it used be. I currently have T-Mobile and
with IPv6 and CG-NAT it's next to impossible to use the old port forwarding methods to run a remote webserver.
But, now there is a free service called Pinggy.? The website below shows how to use it for T-Mobile but it should work with most ISP's as T-Mobile is one of the hardest to port forward from.
So, I use RealVNC to VNC into my sBitx.? If you haven't set up your RealVNC account.? You need to go to
?and set up your free account which allows you to remotely control up to 5 computers for free.? The RealVNC VNC CONNECT software is already installed on the sBitx.? It's the little VNC icon in the upper right hand corner of the screen.? You
just need to have it logged in and the sBitx needs to be one off the computers on your RealVNC account team.
VNC into your sBitx.
Launch the sBitx radio app.
Launch a terminal and type:
ssh -p 443 -R0:localhost:8080
[email protected]
You will get a response like this:
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?You are not authenticated.
?Your tunnel will expire in 60 minutes.? Upgrade to PinggyPro to get unrestricted?
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?tunnels.
? ? ? ? ? ? ? ? ? ? ? ? tcp://xxxxx-nnn-nn-nnn-nn.a.free.pinggy.link:46875
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? Press 'h" for keybindings
Then from your remote web browser on your remote computer cut and paste the tcp address Pinggy gave you above.
But change "tcp" to "http" so:
You should be able to the same GUI(sbitx.local) anywhere in the world now.
If it doesn't work check to make sure you have the sBitx app running on your radio and that you entered the address exactly as you got from the command line from Pinngy just changing
tcp?to http.
Good luck!

Re: Observations in sBitx v3
Remember the power output will change by the square of the proportion of change that you make in those settings. ? Those settings control the voltage game and power is proportional to the square of voltage
Also be on the lookout for differences between CW and CWR power. ? I think often they¡¯re going to be different because of ripple in the crystal filter passband response?

Gwen,
My answer to your first thought is that the weak signal programs that have been operating for years do not work correctly either (JTDX, WSJT-X). I can say that since the v3.0 beta was released in the middle of November last year, I have been using it in ft8 and ft4 mode.
It often happens that if I use split with JTDX, my machine does not respond. If TX=RX, the response rate is better. But you have to be in front of the machine, because I often find that I call 3 times and there is no answer, then I move on.
About the logging: Steve N3SB fixed it in January, it has been logging correctly since then, but the logging repeats after two minutes. This can be changed. I did, but no one fixed the published version. That's why I use some of my favorite modifications. These include RR73 instead of RRR, logging delay, I use qrzcq instead of qrz.com because I can find the missing LOC data there.
AGC OFF is the correct setting.
Since W9JES published the 64-bit version, I've been using it with an external HDMI monitor. So I don't use sbitx's own decoding, because JTDX is much more manageable. It's easier for me to find an empty frequency, which is important to be able to make a complete QSO. I currently have a dxcc/cfm ratio of 120/107 on 3 bands with a single antenna and no tuner. The antenna is a slanted vertical antenna sized for 7 MHz, so it can be used well on 7, 14, 21 MHz.
I recommend that you use v3.02 published with the modifications of W9JES and click on the weak signal if your program does not respond.
