I'm back from a soggy weekend.? Went camping with the youth group from church, it rained the entire time and some younger boys who had a bad tent ended up completely soaked at night.? So we left early and I didn't get time to play pota.? Tried to do some FT8 at night, but I found my RTC battery must have died as the time was way off, and there was no cell service to get it synced, so not a great radio weekend.? Oh well.? Anyway, Peter, yes there's lots of other simple ways to fix this.? I have the tools to do PCB design, and it's a fun side project.? If I order enough boards they will be very inexpensive and no wire cutting needed.? But your solution would work just fine as well.? YO8RC, that's the encoder I had decided to use, so that's great to know!? When I was playing with my radio in my tent this weekend, I counted about 30 'clicks' for 360degree, which doesn't really match the 20 of the encoder we both are looking at.? But I'll give it a go and see what happens.? I should be able to place the PCB order today, but to save costs I'm going with slow boat shipping so it will be about 10+ days before I get the parts in the mail.? Stay tuned!

in fact i will test with an other mixer.
Possibility of a diode out?
in the posts on hbte forum, Dave had changed one, but not precised why
Thanks for your help

Gary, Jack,

Ok now seem good
see code:
Serial.println("Test Gary Anderson Display IF_Freq");
? ? ? ? ? ? Serial.println(setting.IF_Freq) ; ?// Test Gary Anderson
? ? ?
? ? ? Serial.println("Test Gary Anderson Display IF_Freq + choice of frequency generator"); ? ? ?
? ? ? Serial.println(setting.IF_Freq + sigGenSetting.Frequency); ? // Test Gary Anderson. Display total of the IF_Freq and Frequency choice generator

See the serial output:
Test Gary Anderson Display IF_Freq
433920013
Test Gary Anderson Display IF_Freq + choice of frequency generator
444920013? ? --> the sum of 433920013 + 11000000 (Exemple of choice frequency generator)
So normaly on the ouput of mixer -->444920013-433920013= 11Mhz? and 898.840026Mhz (The sum)
So after the filter we must have 11mhz (The 898mhz blocked by filter)
The reality, i see nothing on the output of the mixer. I thing normaly will see 11Mhz??
The same hardware is use in reverse order for the LOW SA and work!

Perhaps you can just modify the Nextion screen. Have never thought about it.

You would need to add a way to set the clock from within Nextion. That would require adding a button to the main screen or the menu section to allow you to set the clock. Then in the new screen you could provide the setting function. I am assuming that accessing the clock is available to the Nextion code and that the clock is not some I2C or SPI address that the nano would have to interact with. I would recommend confirming that first.?

If the clock is only setable by the processor then you are in for some real pain figuring out how to add that. If you must go there, let me know and I can point you to the file you need to get familiar with to figure it out.?

hopefully you can just do it within the Nextion code! ?That would be cool.?

keep us informed.?

Jack,

I think the definition here on the soft
uint32_t ? ?IF_Freq ? ? ? ? ? ?= 433920000; ? ? ? ?// Default IF frequency (***)

i found that on forum Arduino:

The leading u says that the type is unsigned.
The int says that the value is integer (not necessarily an int, though).
The value defines the number of bits used to store the value.

The _t says that the sizes are standard across all platforms.

The size of an int depends on the hardware and software being used. The size of a uint16_t is ALWAYS 16 bits.

Jack,
Don't work
Error on compilation



If you want to have fun with the soft , I can send you all by private message.
M0wid, do not answer anymore on the ISO HBTE forum. I am blocked.

One tip that made things even more stable: Use the P2P mode in VARA.

ps.: regarding the antenna
Low power requires a good antenna. In the picture, I highlighted in red where the wire goes. The highest point is 10 meters, the two lower ones are fixed at 5 - 5 meters. With this delta loop antenna, I can use the device on 7, 14 and 21 MHz without an antenna tuner. The horizontal section is fixed at a distance of approx. 20 meters. Since I have a small area, this seems like a good solution.
Important: I often have to change the location of the transmission frequency, because the 100-watt weak signal stations suppress me. I note that I have managed several dx qso's using this method.
The log data only shows qso's made with sBitx.

I had, it's a ESP32 DEVKIT V1
I have read some where some difference on this command fonction model???

Good morning,
I am addressing you because there are practically no more answers on the HBTE forum. I posted on the Arduino forum, no answer either as if my question would be too complicated??
I made a SimpleSA, it works fine, but I have a problem with the signal generator that does nothing.
I would just like to check (display) with the serial monitor of the main program console Arduino? the value of variables
Variable--> example: IF_Freq which must be 433920000 (these are hertz), another one optionally.
What command line write?
If I put: ?Serial.println('IF_Freq'); ? --> display a delirious value 1181902193 on serial console--->? Hi, i not programmer LOL
Maybe, given the length of the number, we need something else.
It’s all stupid, but it blocks me in my tests
So, the good line is??
Thanks for your help

Lars,
I see that you have an attempt.
What is your output power and what antenna are you using?
I have an output of 15 watts at 7 MHz in ft8 mode and I use a vertical inclined Delta Loop, which I feed from above.
The antenna consists of 43.8 meters of wire. The device is an sBitx v2, which is cooled by the heatsink and the RPi.

The missing screenshot

Rafael, sorry I didn’t catch that you were running it on sbitx.
I’ll take a look at your repo. I may have some questions.(hihi)

FB Rafael.
Yes I run it fine on a pi4 4gb with whatever the iteration of wine is installed with piapps.
It works a treat pretty much.
But again, the audio plumbing and latency induced by the various codecs in the chain may be a deal breaker with the rapid cadence of the modem.

Truth be told when we were working out the bugs with VarAC and Flex, Anan, and SunSDR platforms, Jose did make some adjustments to the modem to add a bit of resiliency.
That being said, that enhancement was to accommodate SDR’s with only a slight deviation in timing.

I’d be very interested to see if anyone has any success on the sbitx,
because I don’t really have the surplus of free time needed to prove myself wrong.

Hi Calvin,

I have not seen a tft file with a clock display.? Two possible reasons:
1 - The models with the RTC are recent additions after most development work was done on the KD8CEC/Nextion software.
2 - There was insufficient memory in the Nextion to allow the extra display or real estate on the screen to fit in.

You could modify one of the HMI files to include a clock function.? Check on Mark AJ6CU's GitHub page:
