Re: LPF-Control PCB TX Logic at U3 & U7
Thanks Oliver.? I recognize this from the sketch.? I use the test code to check the LPF out and let yall' know. The filters alone are working great. Thanks again. Mark KU3O

CW Side tone
My CW side tone is very loud, the volume setting in the CW menu does not have any affect. I am using V12 boards and running Ver 50.2. Any ideas on what to look for? Paul M. KC2TVJ

Re: LPF-Control PCB TX Logic at U3 & U7
There seems to be several failures at the LPF associated with the last software release. Maybe just coincidental ? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner -

Re: LPF-Control PCB TX Logic at U3 & U7
The sketch that aids in testing the LPF is here: https://github.com/DRWJSCHMIDT/T41/tree/main/T41_V012_Files/T41_V012_Software/T41_V12_Software_For_Board_Testing/K9HZ_LPF_tester I don't recall there

Re: LPF-Control PCB TX Logic at U3 & U7
I think my LPF is acting up.? I'm using 66.4.? I built it a while ago and tested it with the LPF testing software, worked great.? But I seem to remember a detailed checklist to be used with the SW

Re: boards and kits and stuff
Raspberry pi works great for SDR's, C and or C++ is standard (linux). I even port a lot of Arduino libraries to the pi for managing I2C chips. But if you want to debug Arduido (or raspberry pi for

Re: boards and kits and stuff
I would suggest that if you want to try using a different processor, just make a new main board and keep the other V12 boards.? The MPU used on the Teensy is either a BGA or a very dense QFTP, not

All: I can't seem to find Rob's transceiver ranking list. Anyone have a URL that works? Jack, W8TEE

Re: boards and kits and stuff
Yeah, I mainly used the discovery board as a test bed for the dual-core processor.? I thought it would make my testing easier given that it came with a display.? That's when I learned how much we've

Re: boards and kits and stuff
¡°Perhaps he can jump in and talk about debugging and library support.¡± Yeah¡­ I¡¯d love to hear what he as to say about that too. He sure got the sBITx working in a hurry after the uBITx¡­ Dr.

Re: boards and kits and stuff
The call sign/grid square info could be moved to the SD card and not be part of the raw code. All you would need is a text file with that info on the SD card and then add a trivial amount of code to

Re: boards and kits and stuff
If I were going to start over, I might consider the Raspberry Pi. It has the memory resources and clock speed to pull it off and a 10" 1024x600 display is less than $50, so overall it costs less than

Re: boards and kits and stuff
*** Amen! The raspberry pi Pico has become my go-to for little projects because it supports SWD ( single wire debug ). Breakpoints. Source level single step. Etc. Shortens development time by an order

Re: boards and kits and stuff
I spent about a month working with the STM32H747I-DISCO Discovery board.? It has good debugging capabilities. My goal was to get a mockup of the T41 code running on the dual core processor, with DSP
By Terrance Robertson, KN6ZDE · #33132 ·
Re: boards and kits and stuff
I agree. The T41 development time would have been years less if there was a decent debugger. I can't believe that the Arduino people don't have the talent to incorporate a debugger in the IDE. Jack,

Re: boards and kits and stuff
My experience with the display is different (better) because I made changes to the design while still using the same display driver IC. The display problems I was referring to are V12 only.? Basic
