Review on 📶 Astatic PDC1 100 Watt SWR Meter: Enhance Your Signal Performance with Precise Measurement by Tutcht Cobb

For a long time I couldn't figure out why my SWR was so high. It turned out to be the meter. The center pin of one of the connectors came loose from the circuit board. This is not surprising since the amount of solder used was certainly sufficient to delaminate the trace. I've tried putting my radio in an open circuit unless I've pressed the connector properly. I'm still getting fuzzy readings. It looks like the switch is connected backwards. I will have to research further.
