Best advice ever! I understand switches need to be debounced and that there is a short delay involved. Is that same delay also necessary between consecutive dits, where i don't release my key? All

In my sleep it dawned on me… ;-) I should have seen it already in the first picture you sent (see attached). Look at the delay between the click of your key ands the beginning of the side tone... It

Thanks, Ben. Apparently this is not proportional to speed, but a pretty constant delay. I will investigate further to find a clue about its origin... Willi Von meinem Mobiltelefon gesendet

This is what i measured. The 4-6ms extra space seems to occur at 10, 20 and 30 wpm. 10 WPM

Hi Willi, I tried also 10 and 30 wpm, saw a delay there also, will measure it after dinner. Ben

Ben, Can you do this with other wpm settings, to see if it is depended on dit length, or if it is a fixed delay? Willi

Yes, it seems they are about 1/10 of a dit-length delayed…. Will try to find out the reason for that…. Willi

From what i can see now, is that the dits are the same length, only the space between the dits is longer when sending a respone with my external paddle.

I did another test. Just uploaded a file with the character '5' (5 dits) for the file player. I recorded from the line output, so no background noise and cllicks. Same issue as you can see in the

That’s interesting! And I must say I have not the slightest clue about the reason for that… Willi

Dear all, I noticed when using the echo trainer that sometimes my responses are somewhat slower. I thougth i was crazy, and my mind was playing tricks on me. But today i recorded a session and checked

Resoldered pin 0 and now switch works fine. 73 and aloha, Den

Here you can have a look as well: https://github.com/oe1wkl/Morserino-32/blob/master/Hardware/Morserino-32_board_v3_schematics.pdf From Pin 0 to Ground.

Dennis, from "technical Overview" document: "A second push-button switch is connected to Pin 0 of the ESP32".

Worked perfectly. Re-soldered pin after touch test you recommended. Final question I promise. The push button switch does not work. Resoldered four pins on switch. Please give me the

Hi Tommy, Here is a link to the driver that Craig N1SFT had shared with us. https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers I also had to load the driver

Hello I have a problem at one of my friends alienware pc's. I cannot find the com port, so my question is what driver do he had to use to connect to his pc? Tommy

Here is a pin-out diagram of the Heltec module. Please check by directly touching the pin on the Heltec - it should trigger the left paddle. After that, check that there is actually good contact at

Using Curtis B. External keyer is perfect. Right Capacitive paddle sends dahs perfectly. Right side doesn't work. What solder connections should I check? Other thoughts? 73 Den

Found schematic for v3 but from the bottom I can't find pin 2 that runs to the left paddle. Need to check that solder connection and the corresponding ground. How can I fund the two pins? Tnx Den
