Other Broadcast Manuals Available Via the BDR

* This list is of manuals on hand or scanned in. Some are just in paper; some of them are just too large for convenient download (25 or 35 MB … or more), others are being cataloged and are available to BDR supporters. Need something? Just make contact. We might have it or know where it is.

Note: Most of these are in PDF format… except where noted.
