Have an old SWR/Power Meter... sometimes it seems to read correctly and sometimes not. There seems to be around a 3-5 db swing depending on the frequency. To test my theory I checked the power meter against the old 141T Spec An and found less then a db of change vs the suspected 3 or so db's. I think I need a better way of measuring power.
The spec an is 10 db /div ... its old but functional. As I tune across the 20m band the power meter is all over the place but the spec an varies less then a db.
