Randy, The same information is covered in LBI-4938C, in the Ericsson format, here:
<www.repeater-builder.com/ge/lbi-library/lbi-4938c.pdf> I found this LBI by using Google to search for "4EF4A3" and found several sources. This LBI is intended to print in landscape orientation on 11 by 17 inch paper. You can use the Adobe Reader "Snapshot" tool to select portions of the image to print on standard 8.5 by 11 inch paper. Many of the scanned LBIs on the GE Mastr Index are in full-page format, and the Snapshot tool allows one to select and print just the image portions that are needed. If you don't have access to a printer that has 11 by 17 inch capability, you can save the above PDF file to a floppy or memory stick and take it to a Kinko's or commercial graphics shop for printing in the original format. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Randy Sent: Friday, December 28, 2007 8:52 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Repeater conversion Thankyou Eric for this information. Would anyone know where I can find the LBI-4100 ??? I have already searched The 'Mastr' Index of GE LBI's, The 4100 is not listed. . . .
