Elecraft has (or used to have) a simple S-meter calibrator that put out a signal that was supposed to be S9 and was pretty inexpensive, if you really need to have accuracy. Then you could check it wit

Is there a way to calibrate it without test equipment, other then a dvom. Like tuning to a stron station while hooked up on the bitx manager and setting the max, and then tuning to a blank station and

Hi, I just received a knockoff programmer and some SMD adaptor boards from eBay. So was able to solder one of my 24 cent processor chips to a 25 cent adaptor board and program it to run a blink test.

Hi, Looks like quite a number of interesting Tips and Tricks, as the title suggests. This is a good collection of solutions much like the old Application Handbooks published by National Semiconductor

I looked and did not see this mentioned and thought it might come in handy, It is from the makers of the Pic Microcontroller but many of the circuits work fine with others like the ATtiny's. https://w

Hi, I found this on-line DSP filter designer that generates C code. Don't know if the Nuvoton 8051 is powerful enough, but maybe it could handle some of the simpler filters. The Nuvoton 8051 has been

Fantastic, great you are up and running. That is good to know that SDCC can be installed with binaries provided on the main site. Thanks for the information on how to get the additional Go libraries.

I got my dev board this morning Tom and with your modified programmer code on Github and and the example it works great! The latest SDCC binaries for all platforms are here and I used the one for MacO

Hi, I have a blink program running on the Nuvotron 8051 chip. After trying out some generic blink programs for the 8051 I found that the author of the original version of the Nuvotron 8051 programmer

Hi, I updated the "nuvoprog" open source Nuvoton chip programmer to now be able to program the MS51FB9AE processor. The code is here: https://github.com/mountaintom/nuvoprog/tree/experimental-releases

The CEC software allows calibrating the S-Meter through the Memory manager when using a simple amplifier circuit, and I did adjust mine until it generally agreed with another commercial receiver. Howe

Hello everyone, i am a new uBitx user, I have built uBitx v5 and loaded CEC firmware for Nextion 3.2 inch display. Moreover, I have incorporated a second Arduino Nano to use it as a standalone signal

One thing that really appealed to me about the MS51 when I read Tom's first post was its potential as an I/O expander for something like an ESP32. What makes it attractive for that are the I2C and SPI

I've used the DigiSpark boards (http://digistump.com/products/1) for several projects including this keyer: While not as cheap as a bare ATTiny85 ($8), it plugs directly into the USB cable and is prog

Another option but not quite as cheap are the ATtiny series microprocessors. They are 8 bit and quite easy to setup to program using the Arduino IDE with an Arduino as the programmer. I recently setup

Funny, I tried that one. Seems like wine did not implement the call needed to print to the console. I would get errors and the help message printed, but not the actual data. Don't remember if that one
