Various Heath Mods

[Freiberger,John]

A few  resources that I use when searching for information previously
 published in amateur radio magazines include:
1. my local radio club; it maintains a collection of QST, CQ, Ham
 Radio, and etc. going back to the 1960's;

 2. the nearest city library having a good Science and Technology
 department, they generally subscribe to  many periodicals.  Issues for
 the current year are kept on the shelves.  Older issues are
 microfilmed and have to be ordered from storage.

3. libraries at nearby colleges and universities having engineering
 schools.  They too subscribe to the amateur radio journals.

Regards,

The mods are interesting and I'd like to see more of them... know of
any easy way of finding these articles since I don't have all the older
QST's anymore?
