[hpsdr] Fwd: Re: DFC

[Takafumi INOUE]

Hi John and all,

I downloaded DFC software from John's github repo. It compiles fine and runs on the Jetson TK1 here.

I can see spectrums and hear demodulated signals but it sounds a little distorted.
So I injected a single tone from a signal generator and it sounded like modulated 
by kind of beep. The spectrum on the panadaptor showed a wider skirt than I usually see with non-DFC setup. 

The clients I'm currently using are KK (audio from the TK1) and your android application. My radio is ANAN-100 with Hermes_21_Mar.rbf loaded. The jetson board receives data from ANAN at the speed of about 980Mbits/sec as far as I can see on the system monitor. I'm using a USB-Ethernet adapter for communication between the jetson board and the client software.

I want to chase down the cause if I have time this weekend but if you have
any clue, please let me know.

Thetis is the new version of PowerSDR that has been updated to work with the new Ethernet protocol. It currently has no special relationship to DFC.

I have a version of DFC running on the Jetson TK1 that I have been working on that supports both the old and new Ethernet protocols. It basically looks like a Hermes card on the Ethernet and responds to the discovery packets just the same as the current Hermes boards. This means it can work with the existing PowerSDR or Thetis, along with my Android and Raspberry Pi software.
