Definition of FM only radio

FM only radio is a radio that receives the FM broadcast band and no other radio frequency bands.  Radio  means it is not a "tuner" (which has no amplifier or speaker) and not a "receiver" (which has no speaker).  As you will see, my FM only collecting interests go a bit beyond this limited definition.


Refinements, exceptions, and other special cases that encompass my FM Only collecting interests

1) Personal "walking" radios (e.g., Sony Walkman)
Personal "walking" radios are included.  The most famous are the Sony Walkman series.  However, the Hastings FM, Jr. was a personal FM "walking" radio that preceded the Sony series.  There are other interesting early examples, like the Sinclair FM Watch Radio.  Less time has been spent locating all the different variations on more recent models, but they will eventually be included.

2) Scanning-type novelty radios
Unless there is some other interesting feature, radios built with the Philips FM receiver chip (variants of the TDA7000) will not be included.  These radios are the "scanning" type.  They have scan and reset buttons and no other method for tuning.

3)  Boom-boxes 
These are perfectly collectable items, but are not included as part of this site. 

4) Early FM tuners
These are clearly not FM only radios, but are an important part of the early history of FM radio.  Classic or unusual examples are included.

5) Console radios
These are included. The Meissner 9-1023 is the only FM-only console I have every seen.  It is pre-WWII.

6) Cassette/radio, phonograph/radio, 8-track/radio, CD/radio combinations
These are generally not included, but at least one rare Hacker "radiogram" (radio grammaphone) has snuck onto the list.  There are a few other special, rare combinations, like the English Electric TV/FM radio combination.

7) Car radios and FM to AM car converters
These are included, but not exhaustively researched.

8) Clock radios
Early FM only clock radios are so uncommon that they are included.  Modern digital clock radios are excluded, but some early digital clock radios are on the list (e.g., KLH TR82, Sinclair Watch Radio).

9) Two-part table radios
Certain table radios were sold with a custom external speaker.  The KLH 8 and it relative, the Advent 400, are prime examples.  These are included in the list.

10) Table-top stereos
Around 1963, certain radio manufacturers offered a table-top adapter to provide stereo for the table radio.  These components operate together as a table top stereo.  Examples include the "Companion" by Granco and the KLH 13 adapter for the KLH 8 radio.  These are included in the list.  The Advent 420s is also included.  It is a descendent of the Advent 400, which is an indirect descendant of the KLH Model 8.

11) Single frequency promotional radios
These are included if they meet the other criteria.

12) Background music (SCA) radios
These are included, but a more careful search is needed to find more.

13) Rack mounted radios
Rack mounted FM radios are a bit unusual.  Some are included here. The National NC-108R is included because it has a desktop brother, the NC-108T.  Industrial rack-mount stations monitors are also included, even if they are just receivers (with no speaker).
