Re: Could the iPhone become an Ultralight ?
I meant to mention one more thing: regarding SDR on other devices, like Android, Webos, QNX, Symbian, etc.toggle quoted message Show quoted text
The main thing preventing SDR on those devices is the lack of stereo microphone input. Note: I say mic *input*, not stereo earphone output. In-phase/quadrature detection requires two input signals, each 90-degrees out of phase relative to one another. So stereo input is required -- though for amplitude modulation modes (AM, SSB, CW) the software can do the detection using just a single input signal. But I digress.
If you hear of any other portable programmable device, other than an iPhone, iPod touch, or iPad, that accepts external stereo microphone input, please let me know. For now, I'm aware of no Android products or any other programmable handheld devices that can support full I/Q stereo input.
