NettetDC grounded antenna connectors prevent electrostatic build up. SWR less than 1.2:1. Meter accuracy is +/- 10% of full scale or better. Has lighted meter on/off switch. These wattmeters are extra sturdy with large rubber feet and a rugged metal and a designer-styled plastic injection molded front panel. Handsome black speckled finish and gray ... NettetI was searching an inspiration elsewhere. An idea of SWR-meter which I´m going to describe in this article belongs to Paul G7EYT. Refer to [1]. OVERALL CONCEPT Schematic diagram of the SWR-meter is depicted in fig. 1. It can be seen that the SWR meter consists of three main parts: directional coupler, two detectors and display unit. … almega it-avtalet unionenThe schematic can be found in PDF format . The circuit uses a standard Bruene bridge as a directional coupler, but with a resistive voltage divider (R1 - R3). The reflected power induces a voltage at pin 3 of the coupler. Depending on that voltage, LEDs SWR 1 - 3 start to light. Because of many variables, the … Se mer The choice of some components is critical:a) The LEDs have been selected to give a good indication of the SWR. Other types might work, but might be too dim to read at daylight, or the sequencial order of the LED display might … Se mer First, wind the toroid. Start with the secondary winding of N=25 turns with 0.2 mm enameled wire. Each passing of the core of the toroid counts as one turn.
