Experimental Methods in RF Design(EMRFD) W7ZOI, KK7B, W7PUA, 2009. This is probably considered the current homebrewer's bible.

Errata for EMRFD

Errata for EMRFD -2

EMRFD Chapter One

EMRFD 1st transmitter mods

Solid State Design for the Radio Amateur, W7ZOI and W1FB, 1977.The previous Homebrewer's bible.

QRP Power, N1BKE and KH6CP/1, 1999

More QRP Power, K2RO, 2006

QRP Classics, KU7G, 1990

W1FB's Design Notebook, W1FB, 1990

W1FB's QRP Notebook, W1FB, 1991

Introduction to Radio Frequency Design, W7ZOI

. . .and, of course, ARRL's Handbook and Antenna Book. I still like 2005 edition of the ARRL handbook best because of all the "projects". . and, the "projects" are labeled as such in the index.
