[Scan-DC] Can anybody help Steve find one of these legacydevices?

[Rick Hansen]

I think they used to be called frequency converters.

Here's a discussion about them on eham.net:
https://www.eham.net/ehamforum/smf/index.php?topic=76326.0 

Google Books has an old Popular Mechanics article that compares the
different brands. This link will be "split" when it comes out in the
newsgroup, and you'll have to past it as one link into your browser:

Here's a schematic if you want to build one on your own:

 There are a number of mail-order printed circuit board houses that can make
the board for you.

Another neat way to have the same functionality is to hook up an FM
transmitter ($10-$30) to scanner, which allows you to listen via your car
speakers.  

May you listen well and often!
