Re: DSP cheap for qrp
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

Has anybody have the experience of the BITX 40 [no mods yet made] deciding
to go into calibration mode on its own?
If so how did you fix it?

I am not familiar with UK rules, but it looks like the uBitX makes an ideal Foundation Class radio from the specs and the description you sent.

Re: No PTT
Hi Geoff,
I agree.
Hmm puzzling, unless the analogue input have all died suddenly. A bit strange.
Ok, A4 and A5 are the I2C lines, when you connect an antenna to the rig, do you get extra noise

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

Re: No PTT
Hi John,
Current consumption is a constant 160 mA, so it is not in 'Transmit'. Tx

Re: No PTT
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

Re: No PTT
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).
