Technical Articles Section
This section contains technical papers I wrote during my time at QRF as published in CATV trade journals and some for the first time on the original QRF.com web site I created. THESE FILES ARE NO LONGER ON THE QRF OR ATX WEB SITE.    These files may be printed as needed for general use by the CATV industry.  ALL may be used for instructional use by schools, colleges or CATV operating companies for introductory technical training.  update2.gif (1754 bytes) Refresh any pages you load as some have recently been UPDATED.  The changes will not be displayed if your browser cache has the older pages stored on your computer hard drive.
