Title: TMC O-503 exciter manual FOUND Post by: Opcom on October 28, 2023, 08:03:10 PM FOUND! Thank you! AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Looking for the manual for the O-503A exciter made by TMC. O-503A/URA-23 TMC civilian version is A-1516, and also called the SBE-2. It's coming without the power supply unit, so I may need that book as well, just to do it right. Power supply is, I believe, PP-1769/URA-23 or the civilian model A-1397. This is an interesting unit which does AM/CW/ISB/USB/LSB. Besides the AM I've always had an interest in ISB with inserted carrier. O-503A images attached. |
