[hpsdr] something for all to read

[John B. Stephensen]

There is no reason that you can't have the best of both. One is a low-IF design and the other is a superhet. SDR also works nicely in a superhet where the analog IF bandpass filter has a small nuber of poles to increase dynamic range and image rejection at large frequency offsets and digital filtering creates a better shape factor at small offsets.

  Alex - Folks!

   

  Yup! About $10K US. Their booth at Fredrichshafen was right across from the Waters - Stanton booth, and the SDR-1000 demo. I could not help thinking, "The best of the traditional right next to the best of the future!" Beautiful craftsmanship!  I do have some pictures which Heino - DJ5ER took, and edited Klaus - DK7XL's release translation for the introduction at Fredrichshafen. Klaus is a distributor rep for this new radio, and authorized service center for SDR-1000, which are totally different categories and market shares. When I get the chance I'll upload Heino's pictures. In a word "Supurb".

  All I can say is WOW. Typical German craftsmanship! I probably don't want to know how much it costs.
  I think we've got a high bar to reach.

  I like the shielding and the inter-board coaxial connections.
  I think we're going to need a bigger chassis for the HPSDR.
