    It IS a "D" model! Got that right then. I was wondering...

    Like pretty much an entire radio.

    The ADS1115 is an analog to digital converter capable of digitizing up to 860 samples per second. That's not fast enough for telephone quality audio, never mind RF.

    If you wanted to operate in the 400Hz band (that's Hz, not kHz or MHz) then it might be somewhat useful, but you'd need amplification plus a CPU to process, demodulate, and make use of the data, plus some sort of output device. The necessary antenna at 400 Hz would more-or-less negate any portability advantages of that chip.

    Considering what they cost the taxpayers, they should be!

    Fun fact: The R-390A was designed as a lower-cost replacement of the R-390.

    Actually, that's an A to D converter. It would need a lot more parts to be a radio. It's a neat picture though...

    This thing on the other hand... :p

    I'm thinking someone might rob me if I am seen walking around the streets with that much copper wire.

    Lol good thing there's also a 20m version.

    For that matter, you could just dangle the radio from the feedpoint of the antenna, and have zero feedline losses. :eek:

    Well, that surely looks like a rig designed by a woman. But where is the lipstick? :D
