Re: Maximum safe input voltage to ubitx?
Hello Paul, I asked myself the same question and poking around the datasheets I believe that 15V for the main board should be the absolute maximum, with some precautions. The reason being is that

Re: Connectors
Perhaps you need to search for "relimate connector". You get male and female connectors. You need to specify pitch and number of pins. All the best sarma vu3zmv Regards MVS

Recommendations for learning coding for Bitx and/or arduino
Okay, I have played with boatanchors and know how to work on tube type radios. Time to learn some coding for the BitX and/or Arduino. I have a Mac computer. Where should I? start? Which books are

I've used both. The OLED is from an upcoming QST article on a dummy load/wattmeter. I don't have a picture of the 4x LCD, but you can can see some sample code at: arduino-info - LCD-Blue-I2C |
