Re: Muffled and poor audio #bitx20help

 

Your mileage may vary.
All depends on what your particular rig's filter shape happens to be, where the stock BFO freq happens to be, spectral content of the voice in question.
I suspect most of these rigs are close to optimum as shipped, though there will be outliers.
Some will be better off with a higher BFO freq, some lower.

Fiddling with the BFO freq to see if that might improves things is worth doing.
I'd suggest that we all just move to driving the BFO from the Si5351's CLK0, make the BFO freq adjustable in the settings menu.
Include a way to measure the crystal filter passband by varying the BFO freq while emitting a CW test tone, monitor at the top of R136 using a diode RF probe, the PA +12v supply into the IRF510 drain unplugged.

I second the C102 change.? Also, monitor your power output while transmitting.? If it is lower than 5W, turn RV136 counterclockwise to increase PA gain as described at the bottom of the page here:.

r is defined more than once.

You're going to get an error or warning for redefining r. You've
definied it globally right under your include statement, then again in
setup. In setup it's only local but you'll still get an error/warning.

Oh, it hears fine, and when conditions are good, I've worked some distant contacts. The radio itself works great! I did 80 contacts with it on Field Day.

I've be using a hamstick dipole in the attic mounted about 4' above the foil backed insulation; not a great idea! LOL! I've been working on a 2 turn, 4' magnetic loop, and last night was the first test. Just had it sitting in the middle of the living room though. Not quite ready to move it to the attic yet as I still have some more hardware & software work to do on the Arduino controller.?

No legal limits to more robust antennas, however I have a rather small lot and I'm getting too old to be climbing on the roof! If the loop doesn't improve things, I'll?build a vertical.

Re: does this sound like a bad encoder or just operator error? #w8tee

That's good news. You should NOT beat yourself up on not detecting the switch...that's my fault. Users of the PCB should not have to worry about what the code is doing. I am going to change the assembly manual to warn them about a likely fix for an "unresponsive" encoder.

The fact that you had to switch the pins back probably means that the INT05 vector is okay on your Mega. I would expect most people to have a "healthy" Mega, but I did read about it on the Arduino users group and I do have one myself. Considering I have purchased about 75 units of the Mega 2560 Pro Mini, that's a pretty small failure rate and might just be bad luck.

Thank you, that did the trick.? I should have compared the two versions when one worked for me and the other didn't.? This fancy Arduino stuff is still new to me but I missed a basic trouble shooting step and for that I got an ear full from the guy in the mirror.? I did still have to switch the pins for data and clock.

Re: does this sound like a bad encoder or just operator error? #w8tee

Jack Purdum
 

If your encoder works with the pins as they are marked on the board and an earlier release of the software, I would use those. I think from now on, I'll put both sets of symbolic constants in the code, but comment one set out, like this:

#define ENCODERPINA ? ? ? ? ?18 ? ? ? // Encoder pin A, interrupt 5
#define ENCODERPINB ? ? ? ? ?19 ? ? ? // Encoder pin B, interrupt 4
#define ENCODERSWITCH? ? ? ? 20 ? ? ? // Encoder switch pin

/*
? ? ? ? ? ? // Try these pin assignments if the encoder does not work with your Mega
#define ENCODERPINA ? ? ? ? ?19 ? ? ? // Encoder pin A, interrupt 4
#define ENCODERPINB ? ? ? ? ?20 ? ? ? // Encoder pin B, interrupt 3
#define ENCODERSWITCH ? ? ? ?22 ? ? ? // Encoder switch pin
*/

This will keep the original set of pins as marked on the PCB and assumes that your board does not have an issue with the INT05 interrupt vector. Note that I changed the earlier symbolic constant SWITCH to ENCODERSWITCH because some builders may have added other switches to the circuit.

Sorry for the confusion.

W8TEE Encoder issues

Jack Purdum
 

All:

I changed the pin numbers associated with the encoder because some Mega 2560 clones don't process INT05 correctly and we were using that interrupt vector on pin 18. I also moved the encoder switch pin at the same time. Look around line 115 in Rel. 1.06 for the new encoder pin symbolic constants:
?
#define ENCODERPINA ? ? ? ? ?19 ? ? ? // Encoder pin A, interrupt 4
#define ENCODERPINB ? ? ? ? ?20 ? ? ? // Encoder pin B, interrupt 3
#define ENCODERSWITCH ? ? ? ?22 ? ? ? // Encoder switch pin
?

If your encoder worked with an earlier release, change the pin numbers you see above back to the pin numbers you were using previously. That should fix the problem.

Also, you do not want to do any Serial.print() or Serial.println() calls in an interrupt service routine. They use their own ISR and you may end up in a blocking situation.
