Ben, I don't think Hijack lets you pipe audio, I think it only lets you capture and record it. The Rogue Amoeba Loopback 2 program works very well for creating virtual audio devices and then piping them. The free trial is a "30 times running" limit, not a 30 day limit, so you could still make use of it without having to purchase the software. At least the last I checked that was the trial policy. Good luck.

Re: Direct Audio into the Mac

Ben Cook
 

That’s pretty cool. I’m starting a CWA session here in a couple weeks and this would be very useful. I do have a Mac program called Audio Hijack from Rogue Ameba which *might* let me pipe the audio in from the built in mic port and a headset into the Zoom conference. I’ll have to give that a try tonight. Else any other details how you accomplished this with your usb mixer?

Correct.  Mumble is full duplex so many newcomers to it have problems with the open mic and a speaker.  Turning off the speaker and using headphones makes it usable, but it is far nicer to have a sound card input.  I do not participate in CW training sessions, but still occasionally need to use a mic with newcomers.  On the Mac, a very nice tool is available (unfortunately it costs the same as the M32).  It is LOOPBACK2 from Rogue Amoeba.  It allows you to create virtual audio devices for mixing and pipelining audio between various apps.  I have one virtual device that combines my external sidetone input with the webcam mic when I need to add "voice".  It is also very handy for playing recordings back to someone over Mumble.  I just select the my virtual device that mixes the Audacity output with my input sidetone to select as the input device to Mumble.

Re: Switch the Heltec for different board for different LORA band

Willi, OE1WKL
 

Yes,

This should do the trick. I will accommodate this somehow as an option in further software version - unfortunately it is not possible to detect which hardware module is installed, it seems. Otherwise I could switch to teh appropriate frequency just by finding out which LoRa module is installed…

Hi folks,

the heltec site is selling the ESP 32 board, and the US version is in the 900Mhz band.

I see only a handful of lines of code referring to the LORA band in the source.

Switching the Heltec 433 board for a Heltec 902 board should be a simple process, yes? Just change the band listing, and everything else should be transparent to the Source code?

Re: ESP32 Board Definitions?

Craig T. Bailey
 

Michael,

the proper board definitions can be derived by entering the following URL into your IDE board manager:

https://docs.heltec.cn/#/en/user_manual/how_to_install_esp32_Arduino


As shown on the Heltec support website: https://heltec.org/wifi_kit_install/

So, basically... the IDE has the board manager tool, and you add that first URL to the manager. Then you choose "add board" and find the Heltec ESP 32 v2 board, and it brings down the entire library needed for the Heltec board.
When you do it that way, the only libraries that you'll likely need in addition will be the ButtonClick library to be able to compile.

Re: Problems with Morserino.

Steve
 

Willi, thanks for the reply.
yes it is version 1.4, and I have checked the two pins to ground as you suggested and there are no shorts. I also checked the pins on the external paddle connector. If I’m correct the screen pin goes to ground ( the one nearest the board edge) but the other 4 are all open to ground.

Re: Problems with Morserino.

Willi, OE1WKL
 

Steve,
I am assuming you are running version 1.4?

In this version the external paddles and the touch paddles are running in parallel; your symptoms show that both paddles seem to be permanently engaged - this could also be a short to ground on pin 32 and 33, or at the jack for the external paddles.
Measure the resistance between32 and ground, and pin33 and ground (if you look at the schematics on GitHub, you can identify those pins - in the schematic the Heltec module is shown from above, with the USB port at the top), to see if there is a short somewhere.

Mike,

If you have a handy kid (grand kid, niece, nephew) they can solder this kit for you.  The only soldering is putting the connectors, speaker, on the board and adding the battery wires. All the surface mount parts are installed already.  It really isn’t a “kit” but just assembling a few parts.  My 11 year old grand son could have built this one.

Might be true ... still discharging ;-)
I got a "broken" E-bike battery pack from a colleague for free and took it apart. Turned out that 45 of the 50 cells are still in great shape .... need to use them for something

Direct Audio into the Mac

Craig T. Bailey
 

Well, I'm pleased to say I've got the Morserino piped into my Mac.

In addition, I built a mixing circuit to blend a wired mic input with the line out audio from the Morserino.

This mixer goes into a USB dongle audio card.

Why? you might ask?

When participating in CW Ops Academy, or any other video conferencing system, where you are working with other Morse trainees, its common place to just let the PC's built in mic pick up the code oscilator's side tone over the air.

I'm finding skype was terrible at clipping the keyer, and Zoom wasn't much better. By having it piped direct, the folks on the other end get clean code. Also, by piping it direct, I'm using my headset plugged into the PC (Mac in this case) as the monitor of the side tone.

I suppose this is also precisely what the Mumble app needs as well.

Just one more reason why Morserino is a GREAT educational tool!

Re: transport casing fro morserino

I’ve charged the crappy $7 lipo battery from amazon once two weeks ago, and been using morserino daily in a 70 minute commute.

That battery he is showing would run it for a year! LOL
