Yellow wire, if I remember correctly

Hi Jack,

thanks for your reply.?

The variables are declared a little bit further up in that part of the

// Token passing flagsfor SWR tune process

struct? {

????????? unsigned Prepare? : 1;??? // Do initial preparations

????????? unsigned Progress : 2;??? // Track tune progress

????????? unsigned Ask_SWR? : 1;??? // Request new SWR measurement - Yaesu special case...

????????? unsigned InitPWR? : 1;??? // Init Power Setting for Tune

????????? unsigned InitMode : 1;??? // Init Mode Setting for Tune

???????? } tune;

int32_t sample[SWR_SAMPLEBUF];????? // Ringbuffer for SWR averaging

int32_t mid_swr;??????????????????? // The SWR at midpoint, SWR_SAMPLEBUF/2 samples ago

Or at least i think that this is valid as a declaration, as I have never seen the "struct" construction before.

I had just mentioned the #define part, as I do not know if this is relevant to the value a variable gets passed.
Also the #define part is in the main *.ino file while the swr-thing is in another *ino file. So i just wanted to make sure I mentioned it :-)

I don't really think the declaration is the problem since everything works if the uBITX is already transmitting -
because in that scenario the progress-variable should get the correct value.

? // Check whether Transmitter is already puming out RF
? measure_power_and_swr();??????????? // Ensure we have one measurement available
? if (fwd_power_mw >= MIN_PWR_FOR_SWR_CALC)
? {
??? swr.rfactive_mode = true;???????? // We're good to go, no setup required
??? progress = SUCCESS;?????????????? // Setup for Autotune is initiated?
? }
?

Wait a second.

I just realized that the stepper motor always starts tuning - it just does not finish the tuning process if tuning is manually triggered.
So I might need to check for "canceling conditions" during tuning in the sketch. Though that does not explain why the progress variable is not printable.

Sometimes just summarizing and processing helps.... Another clue to investigate on.

I just used my EU1KY analyzer signal generator to zero beat my uBitx v5. Yea!
First I coonnected the analyzer to my oscilloscope to make sure 10 Mhz signal was output. Sure enough it was. Then ran zero beat calibration against the generator output and saved. Can hear the minute tone well on WWV 10Mhz, but still getting a lot of static.

i AM INTERESTED. DETAILS, PRICE ETC PLEASE

your vol-hi is on a non-wiper contact on the pot?

my lm386 version works fine on Vol Hi... I think the wire switch is only for the sunil case issue.

I think this is an even better time to point out that there is the "Mute this topic" link below.? Plenty of threads don't immediately interest me, and this is a civilized way to deal with them.? How's that for "high and mighty"! ;-)

Philip,

Thanks for noticing this. I switched the wires and confirmed that things are correct by tracing the circuit and comparing it to the original uBITX wireup doc. (Shows mid-vol going to wiper).

Question, on S-meter hookup.? I am using one of the KD8CEC "simple analog" meters and he shows the input to the op-amp (pin3? "In+") input from Vol Hi...

When you switched the two wires, did you also move the input wire for the sensor so that it was still with Vol high? Seems strange that the sensor is picking its input off of Vol Hi since that will vary with position of the pot. It would "seem" like the input should be the center wiper ("Mid Vol").

Mark

Wow thanks for providing list.?

I still appreciate this list as the first source of BITX family technical info.? Let's not lament an occasional stray, our leadership team will take appropriate action.? We may be the primary social media outlet for a few folk, it happens.?

I do suggest that all of us realize the list is way beyond folk in North America - let's respect other cultures and their economies etc. its a big world.? Cool that these rigs allow a much larger portion of the world's population to literally have a rig, and/or experiment in electronics to do RF.? Keep things global in our perspective.?

Great to be part of this community.?

Perfect!

Sorry missed the location, cant make that event, will wait for the post post, with eager anticipation, Thanks

The quoted THD figure might be just at rated output, and if you don't push the amplitude that far then the distortion might be quite a bit less.

Hi, this looks a great project. Been looking through this thread, but cant find the schematic or code.

Any chance you can point me in the correct direction please

thanks Vaughn

Good to experiment with various options, when they are cheap enough.? some folk merely use an external amplified speaker - in particular when they don't have a speaker already inside their box.?

I am having nice success using an off-board NESCAF audio filter.? It ends with the old LM386 - that should do okay driving a speaker if you are close to the rig.? I may integrate one inside, as it does reasonable SSB filtering also using just the bandwidth control.? I don't see a strong reason to bypass the filter, except maybe for wideband digital mode operation like FT8 and PSK31 maybe (hint those modes don't need a speaker or headphones).?

Curt

Awesome!!

I’m making good progress with stand alone S meter and reformatting the Nextion hmi for a 5” lcd.



Had to redo an hmi because I guess I stated on a v2 GUI and it didn’t have the Dsp support. This is on a 5” screen. I already have the band scanner figured out and I’m working on expanding the scope in the dsp menu. Getting cw to decode across the whole screen on the main screen thing still needs to be looked at but it works great in the dsp menu.
