    I've modified the original FM Spectrum Analyzer layout, somewhat. Here is the latest version:

    Nice with full 88-108 MHz being shown and no apparent "crunching" like the USB device with SDR# has at spots

    Did this subject die? I have been wondering why software or an app that works like a spectrum analyzer (or similar) hasn't been developed to interface with the SiliconDust HDHomerun dtv tuner? Is that an impossibility?

    I came across Signal Hound's Spike Spectrum Analyzer software...
    https://signalhound.com/spike/

    However, it requires purchasing their hardware. I installed the 32 bit software to *attempt* to run it as a test and it immediately searches USB's for connected hardware. When it doesn't find anything, it pops up a box and says "No hardware found", you click the OK button and the software closes.

    I am not a software engineer (not even close), but it would seem there should be a way to run a graphical interface with the HDHomerun like a Spectrum Analyzer. The HDHomerun runs in a network, so it is wireless. The data it collects on each channel is sent to the Rabbitears website for those that use the unit for autologging DTV's. What is to stop a programmer from designing a program or app that works exactly like a Spectrum Analyzer with this unit? I've sent emails to the tech team at Silicon Dust about this aspect, but haven't had a single reply from them on it. Maybe they have something they don't want the end user having.

    I've also wondered if SDR programs can tune the DTV bands and if an application like that could access the tuner information from an HDHomerun.

    I came across this tutorial on making an RTL-SDR application work to receive/decode/record ATSC signals. Has anyone that is already using an RTL-SDR, tried something like this yet?

    I followed all of the instructions in the tutorial above. I installed HDSDR, EXTIO with the drivers. I am NOT wanting to record any TV/audio with the software application, just use the waterfall feature (spectrum analysis) to tune to DTV channels. BUT - in HDSDR I can NOT find a way to connect to a network. Was this program ONLY written for hard-wire connection (USB) ??? If so, I guess it doesn't go any further than this.
