Re: Line In/Out Pinout to Mac

Ben Cook
 

Thank you Juergen,

I verified all connectors on the board to the TRRS cable look good. So no issues there. Also in case it helps anyone else, the solder points from the previous photo bottom left moving clockwise are: ring 2 (ground), ring 1 (line in), tip (line in), and sleeve (line out).

I did overlook that part of the manual. I was able to adjust the audio in on the Morserino according to the manual. I tested that it can receive and decode morse code when generated by the computer! So, we are narrowing in on the input issue of getting the line out from the Morserino into the MacBook Pro.

Birk mentioned that maybe that Mac doesn’t detect the Morserino as a microphone. I believe that is the issue right now. I measure DC voltage across the TRRS ring 2 (ground) and sleeve (audio out) so I believe the Morserino is outputting audio voltage.

Yes Ben,
i think thats looking gud: TRRS = 4 contacts - and 4 are soldered. The unused may be switched connection points.
You know the automaticly switches off speakers when u pluged in a headphone...

So next what i would test with a OHM-meter: solderd connection points and the TRRS at the cable.

And then there may be an un-read point in the manual (pg 6):

....
A long press of the RED button starts a function to adjust the audio input level (and possible the output
level on a device you connected to the Morserino-32's line-out port).
....

Hi Juergen,

Good point. I connected the audio out to an amplified speaker and heard no audio. Tested with the headphone jack and got plenty of audio. This made me thing there might be something wrong with my soldering job or the component. Sure enough, when I tested, the two pins in the yellow box appear to be connected even when not keying. The solder joints don’t look connected, so I’m wondering if I got a bad component or where to check next. None of the other pins seem connected.

Hello Ben,

that there is the keyed audio at the sleeve ? My first idea is that there is no audio there !

Good morning! Trying to figure out why the TRRS pinout from the Morserino to a Mac input doesn't work. Looking at the manual and then looking at the Mac's pinout, it seems like this should work with a straight through TRRS male-male cable. I learned today this appears to be the CTIA standard.

apple pin purpose morseino pin purpose
tip left audio tip line in
ring 1 right audio ring 1 line in
ring 2 ground ring 2 ground
sleeve mic/in sleeve line out

Yet when I plug the Morserino into my mac and go to the CW Keyer, I see no audio coming into the mac. When I go to the iCW function on the Morserino, I see no audio coming into the mac. I'm missing something here, but not sure what if anything to splice in the cable to make this work. Some additional insight appreciated.

My guess its similar with most phones - I can't image how they would otherwise electronically detect the difference between a 3 connector plug (--> just headphones -->  leave the internal microphone of the phone on) or a 4 connector plug (--> switch the internal microphone off)

@Ben:

What I did:
After figuring out that my phone is alway leaving the internal microphone on (and not turning to "external" microphone aka morserino) I connected an normal phone headset which ... surprisingly worked. Then I measured the resistance of the microphone and put in a resistor for mimicking that.
Don't know about the sound quality though.

If your MacBook also has to decide if there is an external microphone connected or not and you are not receiving anything I guess its worth a try...
Maybe you can doublecheck in the sound setting the changes of connecting normal headphones vs. connecting a headset. If there are automatic changes there I guess you found your problem.

Re: Line In/Out Pinout to Mac

The TRRS pinout for an Android device is actually different from an Apple device. One of the things I learned yesterday. Basically the microphone for an Apple device (CTIA standard) is on the sleeve whereas the microphone for an Android device (OMTP standard) is on the 2nd ring. The ground position just flips depending on where the microphone pin goes.

I’m curious too what happens when you go from a TRRS to a TRS. Does it just mesh the audio channels together? Or just eliminates the mic? That will be the next thing I look up.

Time out selection

Bruce
 

For the Time Out set preferences I have been selecting No Timeout but it appears this setting is not saved in memory
so after turning off Morserino then back on reverts to 5 min default.
Shouldn't this preference be saved? I believe I am doing everything correctly as i have changed paddle type to no squeeze and that gets saved Ok.

Re: Line In/Out Pinout to Mac

Final solution to get the audio out from the Morserino to my mac was to buy a $9 USB TRRS audio input on Amazon and that worked first try! Here’s a link to what I bought in case anyone else needs the same: https://www.amazon.com/dp/B07RS11M1T/ref=cm_sw_em_r_mt_dp_U_4vVBDbN8DSAS3

That now coupled with the Loopback program for the Mac is awesome for my CWA course starting this week! I can get the headset to work for mic and audio out and mix that with the cw audio from the Morserino.

Thanks for all the help and patience folks!

This should work. You just have to make sure to completely leave the parameters menu (with long button press) before you power off, so that it has a chance to write to non-volatile storage.

Willi,

I just tried that and still reverts to default of 5 mins, however changing to 10 or 15 min timeout it does save that selection. So it seems it will not

save the no timeout selection.

You were right, the option „no timeout“ did not get saved. This bug will be corrected in teh next version thanks for the hint and testing!

Feature Request

 

Wili,
Please consider adding a new keyer mode.  On the K1EL keyer it is called Straight or Bug mode.  You would process dits the same way, but dahs would be manual.  I.E. you turn the device into a "Bug".  This would allow an external Straight key to be plugged into the dah contact or a true Bug connected to the dah contact.

Re: Feature Request

Willi, OE1WKL
 

Aug,

I put it on my to do list.
It is a major change though, as currently I do not support manual keys at all (except for the „Decode“! function). The reason is that the Keyer function „generates“ characters, while with a manual key the device has to „decode“ the characters. Now basically a decode function is already there, but its integration into the keyer, echo trainer and transceiver functions is not trivial.

I‘m convinced Willy can make all these additions. But I think it depends on the battery, which possibly will not fit under the Heltec module

More practice files

I uploaded some practice files to the GitHub Repository, that are useful for practicing with the Morserino-32's file player capability (https://github.com/oe1wkl/Morserino-32/tree/master/Practice%20Files).

- The file "checkpartial_contest_calls_random.txt" contains more than 37.000 call signs, that had appeared in major contest logs over the years, taken from checkpartial.com.

- The file „RealQSOs.txt“ contains a large number of realistic QSO exchanges, and I am grateful to Bill, G0ELZ, for giving permission to use this file, that he and Gordon, G3DVW (SK), wrote up over a number of years.

- The 3 files „phrases_2_words.txt“, „phrases_3_words.txt“ and „phrases_4_words.txt“ make use of commonly used English phrases, 2, 3, or 4 words long, respectively. They have been contributed by Tommy, OZ1THC.

Re: Direct Audio into the Mac

Thomas Ruhmann
 

Hi folks,

I soldered a cable from the morserino TRRS input/output to the input of a external USB soundcard and get the sinus tone as input. Then I tried to reroute the tone to another soundcard output to hear it.

I´m actually in the first cw academy course and think also about piping in the cw tone directly to Zoom.

My problem is, that the latency of the output tone is to long - so there ist no hand-ear synchronicity possiible.

I´m using Windows 10 with VAC and Audio Repeater for routing. Any ideas to decrease the latency?

Best regards Thomas DG6UAX

Re: Direct Audio into the Mac

Craig T. Bailey
 

Yep.  I’m in the same boat with the latency.

 

I’m designing an external circuit based around the OpAmp which will combine the audio out from Morserino directly into the headphone output to work as a direct monitor.  Of course that morserino line out is also going to be SUMMED with my headset microphone, and that SUM signal is going to be fed into the lineIN on the mac.

 

I’ve given up on the software audio mixing.  The latency is just too much.

 

But, something must be designed soon, and produced cheaply, because so many of us are doing Morse into Zoom/Skype, and the audio coupling is just horrible.

 

Not to mention those PC Mics that do not even trigger until 30 milliseconds after a DIT is played… learning Morse over zoom is actually harder because of all these audio problems.

 

Then we have some guys that must be using dial up connections… the list goes on an on.

 

I really started hating the CW Academy classes because of the audio challenges.  SO much, that I eventually bailed out of Level 2.
