HF Signals is getting faster!? Ordered a uBITX on April 03, got shipping notice via PayPal with a DHL tracking# 5 minutes ago - 4/25/2018.? Should arrive in KS in about 4 days if DHL runs like

Giuseppe Thank you for sharing wonderful project. I did not even try because stm32f103 does not have fpu and dac. (Compilation is the same, but FIR and IIR are implemented internally as software) But

Hi, I shared a project of an economic and simple dsp, it is based on the processor arm cortex stm32f103 whose module is at a cost less than two dollars in online shop. I implemented two narrow cw

Hi John, Current consumption is a constant 160 mA, so it is not in 'Transmit'. Tx current was about 460 mA. Geoff

Hello Geoff, With no key pressed on the CW input your voltage is logical. But earlier on you mentioned 1Volt on the PTT and that is not normal. If your Raduino was to see a low PTT logic it would

Hi All, As of KD8CEC firmware v 1.072 and later, I2C LCD? displays are supported. See the firmware manual for how to edit ubitx.h to select the display type. Rod KM6SN

Hi John, The 4.7k has 5v on one end and slightly less on the other. I will isolate the encoder and try again. Geoff

Hi Geoff, I just realised that you can't use the push button either so you won;t be able to access the voltage monitor, so forget the last point about the other software. One think I find strange is

Hello Geoff, So I would say the 5V is fine, your Arduino is working as what is on the display is coherent and at least a set of digital output are working (as they drive the display). From what you

Do you have the 4.7K on the key line soldered properly? Worst case you will need to replace the NANO. If you are experienced fine otherwise take some help so as to not damage the raduino board when

The oleds can have a very high rf interference depending upon how you mount them. They are a current hog too.. Go into this carefully. - f

and I have just done so. Bill, VK7MX

I should also say that the display lights up, saying "VFO A? 7.150 MHz, it will not tune, although the encoder shows 5-0-5-0-5-0 at the pins as it is turned. Pressing the knob 'in' does nothing.?

Fabulous work, Now, do two more things : 1. Using a volume control in the front end, measure the resistance at various settings and read out the readings on the analog port. 2. Using this as a chart,

Any stray adapters left? Discovered a couple of spare boards in need of the dds variety that seems to have become unobtainium. Ross vk3ucr

Dave that’s a great idea with the fan powered on only when in transmit I might do the same thing here. I’ve got a few very small fans here salvaged from somewhere and they are quiet too. Have you

What's the problem? 73

You are correct. However, they've already been freed up. The stock Raduino has 4 data bits to the LCD.

I was under the impression that the existing 2x16 LCDs could be used in 4 bit mode or 8 bit mode which would free up 4 pins. Many alternatives ....OLED displays with IIC interfaces, etc etc.....but

Thanks for the advice Skip.? Did some long transmissions on 40 and indeed the power transistors did get pretty hot. I had not noticed it.? Went to my box of computer parts and pulled out a nice
