Vince, Hate to differ with you, but despite all your suggestions, the solution to the SD card read failure is, as Bruce suggests, a coding issue. Tinkering with the code line values in Bruce’s hack,

Secrets to getting the card to work. First, review page 9 of the User Guide (Part 10) found here http://w8bh.net/MorseTutor10.pdf Then, 1. Ensure you are formatting the card in FAT, not FAT-32, not

I have located a schematic for the ESP32 version. I've attached it in case someone else needs it. (PDF warning)

I've built a couple, I don't remember a schematic, and I didn't find one in my project doc folder. The pcb is well labeled, that's what I used to build. You can take a pinout of the ESP32 module and

Does anyone have a schematic for the ESP32 version of the tutor? I've checked the website and github, perhaps I've overlooked it? thanks/73 de VE6LK ..Vince

Bruce, Thank you for the tip. ?I believe the change ("hack") had already be performed so I changed it back to a "1". Still no success. ?I returned the value to "0" and saved the sketch, followed by

The problems continue. I am getting a MD5 checksum mismatch. Dean Davis, KL7OR President, The 3905 Century Club, Inc. (3905 Master No 80) -- This email has been checked for viruses by Avast antivirus

For the missing first character, consider trying the following "hack": In line 947: strcpy(list[count++],&entry.name()[*1*]); // add SD file to the list (ESP32: remove '/') *change the "1" to a "0".*

I am having the same problem. First letter of the filename is truncated. I have filename like test.txt, example.txt, preamble.txt I tried a little test. I also uploaded a file names reamble.txt On the

Mitch, I put mine in an aluminum box. I only 3D printed the front and back panels because I didn't want to drill the aluminum (and it looked cool). Perhaps someone else has 3D-printed a full

We are getting off topic here. I am looking for stl files for the *NTP-Server* , not the MCT. As Bruce commented, there are a couple of designs available for the MCT. Any leads for a 3d box for the

Hello Bill. You asked what color enclosure I would want for the MCT.? I am not choosy.? A friend made me an enclosure for one of the mct's but it does not fit the board it was for.? It was the

I don't know the formula but when I sent the gerbers it was $33 for 3 boards. I found that very reasonable and I have always been satisfied with the quality of their work. So I ordered them. :-) Worst

Hi Bill! If China is an option, you get 5 PCBs for $2 or 10 for 5$.... (10cmx10cm)+ postage... The place you mention is 3 copies 5$/square inch Karl

Thank you. I grabbed all of it. Have never had PCB's made so not sure what the next step is but it will be fun learning. I have bought a number of PCB's from OSHPark I will have to try and figure out

Hi guys! You can find the gerber files etc.for the tutor here: https://kj.skontorp.net/MCT/ 73s de Karl - LA3FY

Hmmm. I don't have the LA3FY PCB. Maybe that's the one. I have the W8BH, the KI4PSR and a third by KS4NS but, as I said, they are all too big to fit in the box. I have a completed W8BH and it works

Yes, and I spoke with Jack (I am already in the other group) and he said he never did a PCB for it. Someone had to. The mounts for the board inside that case are smaller than any of the other boards.

Oh, thanks for the link. I missed that one. Wil
