    You might try to get the software to work under Windows Compatibility Mode.
    Some software requires compatibility mode to run on Win-10....

    My old college electronics teacher, Hugh Wells, W6WTU wrote a whole pile of articles about UHF tuner applications (particularly varactor tuned ones) including a high performance spectrum analyzer for a couple hundred bucks!

    You have the gutz for a basic sweeper, add an amplifier ALC, a marker adder...
    And you can do all kinds of wonderful things.

    Ive tried, it wont even work with virtualization, it has something to do with 64 bit from what I can tell running it through IDA Pro (disassembler) , so it could actually work on win7 32 bit im not sure. I just dont have time to mess with the thing at my knowledge level in RF my scopes FFT an SDR and a noise generator help me out quite a bit. I must admit being able to see 900 or 2,4ghz of spectrum all at once would be nice! I have an analog scope that is also in the shed next to my 8 digit DMM. The problem is the scope is a HUGE old 500Khz HP rack mount, I have no room to dedicate to that. Im not sure if this is even a usefull kit anymore with the advent of a dongle with up and down conversion? If it is I would definately put it on the sales forum as a trade im sure someone out there has a collection of dual band radios. The E-Book I purchased is great though it acually has very little to do with the kit and a lot of articles on w70zi spectrum analyzer with other designs, very good learning material.

    The hottest diode I ever found for a crystal set was dug out of the insides of an old phillips TV tuner.
    it just snapped into a holder like a fuse (but a lot smaller)

    The Science Workshop does (or did) offer the "Poor Man’s Spectrum Analyzer" kits based on the use of varactor-tuned TV tuners. See http://www.science-workshop.com/. IIRC, it made it into Radio-Electronics and other magazines.

    WA7MLH is BIG into homebrew and has built SAs. See http://www.neoanderthal.com/wa7mlh1.htm (scroll down to "3rd generation spectrum analyzer").

    As Bryan noted, there were a number of articles in electrinics magazines
    using surplus tuners.

    Wes Hayward, W7ZOI and Terry White, K7TAU wrote article for August and September 1998 QST magazine issues. .... Poor Man's Spectrum Analyzer using surplus parts.

    He updated those reference documents, earlier this year.

    it wasn't just the tuners that were so good. I've still got quite a few pieces of gear that were made from old TVs. About the only part that wasn't really useful was the CRT. My first homebrew Superhet was built with about 60% used TV stuff. It wasn't pretty by any stretch of the imagination.... and it didn't work as well as some of my later gear.... but it did work, and it cost almost nothing to build, thanks to an early 1960's TV donor.

    Much of what was in the Southgate Type 4 came from old TV sets:
