Tom: That video is really old. I'm not sure it uses the ALP decoder. Try the new one again: https://vimeo.com/manage/videos/867003483 I reposted it after Jim Pruitt rotated it for easier viewing.

Re: #t41-ep RTTY Contest #t41-ep
Out of interest the radio is using my latest front panel. It uses a RPi Pico to interface the encoders and their switches, the touch screen and the 2 LEDs. The 18 switches are connected to the keypad

I probably have two dozen keys and one of my favorites is the micro switch Hans had on the early QCX's. Go figure... Jack, W8TEE

Re: #t41-ep RTTY Contest #t41-ep
A friend bought the key in a charity shop and gave it to me. It had not been used so was in perfect condition. Had to get used to it after using a paddle for some years. -- John G0ORX

Joerg & Jack, Just soldered some pins to VBAT and GND on the Teensy, applied 3v, and the RTC is working. Thanks to everyone, Paul, KI7LW

Re: Alternative to Teensy 4
It was not an Ethernet chip that was removed; it was the Cortex-M0+ (IMXRT1062), which is used to flash the Cortex-M7 (MIMXRT1062DVJ6B).? My mistake.? I have not used a Teensy for years, but it¡¯s

Re: 4SQRP T41 update
Can you 'edit' the video so it is horizontal rather than vertical?? Or tell me how to adjust my view of the vid? Thanks & 73

Re: Alternative to Teensy 4
I looked at the Debug Mod Project.? ?I believe that the Arduino IDE will no longer be able to work properly, so we'd have to move to Platform I/O, VSCode or eclipse.? Also libraries are added to
Re: DCF77 Time Signal #display #t41 #t41-ep
As Jack wrote earlier: You only need to connect a 3V battery to Vbat of the Teensy and the internal clock will not loose time. There is a thread on the SW side in the PJRC forum:
