I submitted to Repeater Builders (WA6ILQ) the Programming Section (IV.) of the HAL ID-1A REPEATER IDENTIFIER Manual. This section describes how to properly solder the diodes (1N270) in the DASH Matrix and SPACE Matrix of the ID-1A for the creation of a CW message (Repeater ID).
This section of the 1972 HAL ID-1A manual was OCR/Image scanned, cleaned up, placed into MS Word format and then an Adobe Acrobat (PDF) created. This document is high quality, easy to read, and current document standards. The 1972 copyright is retained by HAL Communications (Bill Henry, president) and noted on the footer of the refreshed document. I did add one UPDATE to the refreshed document. The 1N270 germanium diode is no longer manufactured. The Central Semiconductor CDSH270, a Silicon Schottky diode specifically designed to replace Germanium diodes like the 1N270, 1N277, etc. is a recommended replacement. This newer technology provides lower forward voltage, lower leakage, faster switching speed, and a more robust package. Mouser part # 610-CDSH270 is a reliable source for this diode at about 25 cents each (2008). The HAL ID-1000 uses a DIFFERENT Diode Matrix format, SO this manual excerpt is not helpful for that newer CW ID model. w9gb
