Au tomatlcally computos standing+ave ratio in 50-ohm coax feeding an tenna and delivers analog voltage for ddving meter or digital display. Inputs are forward (VFIN) and reverse (VRIN) voltages as convention-ally measured for SWR checks. Requires regu Iated ±15 VDC supply at 40 mA. Article gives construction details and covers adjustment of critical resistors during alignment.-T.May-hugh, A Digital SWR Computerl, 73 Magazine, Nov 1974, p 80-82,84, and 86.
