Jack Odd part it complied all the way thru on once, did not change anything and after that I started to get error?

Unless you have some reason for using John's code (I know he's got some interesting stuff going on), I would suggest you try Oliver's code. (https://github.com/KI3P) If you need some C programming

makes sense Jack. not much of a programmer here. I am using John's 50.2 sketch off gethub KI3P ( https://github.com/KI3P ) / *T41-V12-SDT ( https://github.com/KI3P/T41-V12-SDT )* maybe that is wrong

I think this is what you're looking for: ArduinoJson/src at 7.x · bblanchon/ArduinoJson | | | | | | | | | | | ArduinoJson/src at 7.x · bblanchon/ArduinoJson ?? JSON library for Arduino and

Some versions of the code do use Serial and Serial1. If you are working with CAT control, Serial1 needs to be defined somewhere. Jack, W8TEE

A variable with an extern declaration makes no sense with a static definition. The keyword extern is used as a decaration for a variable so the compiler has an attribute list of the properties of a

I fixed the Adafruit issue (I think) first compile went OK? then on up load and additional complies I get this: C:\Users\Admin\Documents\ai6ym\t41-main\software\SDT_Main\SDT_Main.ino: In function

Found a couple of versions think I finally got correct library version 7.3 Now I get this message: C:\Users\Admin\Documents\ai6ym\t41-main\software\SDT_Main\BPF_Control.cpp:9:26: warning: 'mcpBPF' was

I think you can install the ArduinoJSON library with the Arduino IDE library manager. - Jerry, KF6VB

*** I'm using three of them. Two on the main board, one on the RF board.. I think. Haven't heard any noise. If there is noise from those regulators, it's drowned out by the noise from the video panel.

Hi All, Playing with CAT control of my T41 today. Clearly, nobody's messed with this for a while. To get it sort of working, I had to move the invocation of CATSerialEvent() to a place in the loop

V12 boards using Ai6YM kit. 50.2 build. I am trying to reload IDE to see if I can prevent program hangs. Will only run a short time before it stops running. I have all the libraries loaded and get to

Has anyone that's used these seen any noise problems?? The data sheet states the switching freq. as 500kHz. Mike K5ESS

*** I remember my old TRS-80 model 1 - I once tried to use it with ham radio, NO WAY! It made so much RF hash that it would get into the TV set at the other end of the house. I think that was a few

Didn't know that...thanks to both! Jack, W8TEE

I'm building a new LPF board. I've wound all 33 toroids and have no feeling in my finder tips! (The wire (#20) doesn't lend itself to the Crochet Hook Method with the small cores.) Now I'm tweaking

Hmm - at 14.2 MHz with the gen set to -72dBm ( as low as it'll go without an external attenuator ), I'm seeing just a hair under S9. Not bad! 7.2Mhz - just a hair under S8. Well, on that band the BPF

Hi Jack- Joerg, DB2OO contributed code to T41EEE which allows calibration of the S meter. Here is a description: ---------------------------- dBm Signal Level Calibration ----------------------------

I didn't say that right. The calibration of the s-meter sets the ZERO point (well... -73 db point) on the meter. That is the intercept of the equation for "S" units. You also have to calibrate (eg

BTW, when doing something "sensitive" like this, if your computer is close by, turn it off. Eary in the T41 development, I was really disappointed in the noise it was picking up. Then in a "duh"
