Yes, and the audio was very weak and poor. Tinny sounding. I took out the element and replaced it with a electret mic. Ed W0OIC

thanks but i was looking for receiver only.

Thanks for the input, Farahan. We use the little 1" OLEDs on the Morse code Trainer with excellent results and they are extraordinarily legible using 4 lines. 73 Kees K5BCQ

Well, my 1st read of your Foundation License as a YANKEE -I have to say is pretty easy to understand. However... The unknown is...and a Queens subject can affirm it at the next club meeting. A very

Have you seen http://bitxhacks.blogspot.com/2017/10/raduino-as-nbfm-tx.html#comment-form ? It is not all of what you asked about, though. 73 de Daniel KB3MUN

No, but I do use the Turner +2 with the 4 pin wiring and it does very well. Ron KJ4FFG

Has anybody used a d104 mic with the ubixt? I

Calibration mode is normally only entered when the red wire is connected to ground. Make sure the red wire does not touch ground. Noise on the red wire?(due to poor ground connections, poor SWR,

You also have to connect the Common (center pin of the three) of the encoder to the "ground" (earth) on the raduino or it won't work. Jim, W0EB

A question, where does the encoder get its supply from? Geoff

Hi John, Now, I connected the unplugged Raduino to the USB socket of my computer, and it lit up. Connecting the two encoder wires only, black & brown, has no effect when the encoder is turned. This

There is an article on the hfsignals page on calibrating the bitx40. It seems like when the red wire goes to ground it goes into calibration mode. Did the red wire touch the chassis or board.

Ubitx ordered on 4/3/18. Shipped today, 4/25/18! Wow they are really hustling to get caught up. Better get working on my antenna.

Hi Geoff, I am at a loss as to what could be the reason for your problem then. The thing I would do if I was in that situation would be to go bare bone: remove the Raduino from the main board and

Check the voltage on the wire and if it is 5V then bypass with a 0.1 to remove noise or RF influence and see. Do all soldering with power OFF ! Raj

HI Jay and thanks very much for your suggestions. For the benefit of others, here is what I did. At our Hackspace night, we loaded 1.07 by KD8CDC. Read this

Hi Jhhn, Yes, large increase in white noise on connection of my 40m dipole. Geoff

Thanks, Ian, you are right, the cortex m3 is a small processor unit, and no DSP extension like the f4, the main reason was the price of midules, I got one module for less than 2 dollars, and the

It is a possibility but is more difficult to obtain good results results of FM demodulation @10.7Mhz. Anyway I will try to demodulate FM directly @12Mhz. Instead of the?FM demodulator coil I can try
