Sony XDR-F1HD Seeeduino Modification
This very usefull modification, detailed here, was undertaken in Sept 2012.
The latest software has considerably-expanded command functions that were not available then.

(jumpers were later bundled and exited thru a drilled hole in the rear apron)
This graph was obtained by using the "S" option numeric data dump at 100-kHz intervals with the numbers entered into Lotus Works Chart Maker and the two (88-98 MHz and 98-108 MHz) graphs
being joined and calls added with PSP4 - an admittedly-arduous process not likely repeated.
After the graphic interface was implemented (again, more extensive there now than when I did it in Sept 2012) some of these initial results were obtained
(the saved png images, with date stamp dd-mm-yyyy, were modified in PSP4, with the calls and freqs being added)
On each set of these graphs the IBOC (HD) "sidebands" of the locals are very evident.
98-108 MHz scan Sept-08-2012 - 1914 CST
(the dynamic vertical scale continually adjusts to just fit in the max signal level on the display)
scan showing part of ATSC (DTV) KCWX-DT-5 (76-82 MHz) with prominent pilot at 76.310
showing fading effects (mostly due to aircraft)
on XHPN-3's 61.250 NTSC video carrier
RDS decoding on KXBJ 96.9
(European PTY set so not matching US system)
At almost the same time the RTL2832U USB dongle system was "discovered" with its ability to show a more-dynamic spectrum-analyzer-like display so the initial
flurry with the Seeeduino quickly (somewhat unfairly) rapidly abated. However, that device (in 2-MHz wide segments) was subject to saturation/overload and
spurious responses from much of the local high-intensity 88-108 MHz environs at this location as seen in this YouTube video.

SDR# display centered on local 89.1 MHz - 09-14-2012 - 2020 CST
(those are SCA sidebands on it and 88.3)

SDR# display Jul 8, 2013 - badly overdeviating by local 93.7 LPFM
SDR# display Jul 9, 2013 - close-up of local 106.7 HD - note how sharp the sidebands fall off at 106.5 and 106.9
