Re: V12 compiling error

Just so you are not misled here¡­ the audio out from the main board needs to go to an external audio amp to hear stuff from a speaker.? The output from the audio jack J14 (from the PCM5102) is about 2V maximum¡­? That may drive some high impedance headphones but not a speaker!

I think audio is hardware I will check Daudio out on Tweensy to see if signal is there, if so then it is U5.

I reloaded Jack's beta and it has working S meter and I see signal in filter window.

I can try reloading yours later.?

I loaded it using Tweensy Loader, could not quite figure out how do from Arduino IDE, as Dr. Bill says it may not be obvious.

You guys are great , last real programming I did was in 90's !?

The Arduino IDE keeps getting better I remember the days before the Library manager, much easier especially loading zip file from gethub!

I believe water fall was working in Jerry's just no signal in Filter Window
Jack's beta both water fall and filter window is working FB.?
?
I have noticed that on startup the signal strength is initially low and builds to reasonable level in a few seconds or so.
Might be AGC related.

In Jacks Beta the S meter was working, this version the S meter is not , don't see a signal in filter window either.

I the next release it will be easy and intuitive instructions are on cal screen, easy peasy.

Re: V12 compiling error

 

Interesting. I've got that software running on my V12 - working S meter
and also audio out.

I have my T41 in pieces right now as I'm putting in a new LPF board and will be moving it to a new case. It will be tomorrow or the next day before I can check this.

Loaded fine Jerry
Only issue now is I have no audio out, seems to be a hardware issue on my Main Board.

You can, its just not obvious in the IDE¡­ but you can always load HEX code directly

That is a raw dump, I think, couldn't load in arduino progrmmer

Re: V12 compiling error

 

It's a hex file. You should be able to upchuck it with the Teensy programmer.
It ( the programmer) has an "Open hex file" function in its command bar at the top. I sent it to you so you could just see if your radio worked, without
worrying about libraries or compile options.

TNX Jerry I will compile and let you know.
I got my head around using Arduino programmer again.

Re: V12 compiling error

 

Yes RX cal works fine?
Will there be an option for different PB configurations?
My front panel designations are different than yours.
Tnx for all the help, Tim
Re: V12 compiling error

 

These look right, now. There's still a few things left for us to fix, but we're close.

That's the right file. Did you optimize for smallest code with LTO? And you are using IDE 2.4.3?

My PB's are not what they were before Probably need different menu file?
I noticed that Calibrate RX is way wonky doesn't look at all correct.
But it is running I moved fan around maybe that helped I don't have back on case fan is just positioned near Tweensy?
Temp says 42 degrees C

Re: Initial RX calibration not working

 

Apparently I've missed the write-up on the V12 receive calibration that Tim is referring to.
Any chance that someone can point me to where I can find it as well as the latest software
version that he is using.? I haven't been able to keep up with all the changes and I admit
to getting confused (old age??) when messages refer to software or other documentation
without a specific reference.
?
Thanks so much!

Re: Rob Sherwood Presentation Slides on Amateur Radio Transceiver Performance

 

Yes Pure Signal is open. Go take a look at Thetis for the Anan or Hermes/Hermes Lite radio.
?
My simplistic thinking is that it works a bit like noise cancelling headphones, except the thing cancelled is the noise (distortion) added to the signal by the Tx chain not the external noise.
?
Delay in the Tx chain exists but I don't think that stops the predistortion from cancelling IMD. The IMD created in the chain for a given input to the chain should be deterministic and repeatable.

I thought the "Pure Signal" pre-distortion software was open source?
