What I thought over all these years (since 1964) a 50 ohm load was actually a 68 ohm load after many years in oil and many heating cycles. ---------------------- There was a report about this problem some years back in Radcom and the answer came from no less an amateur than G5RV. Apparently over a period of time some types of cooling oil in the Heath Cantenna and similar types can have a chemical reaction with the carbon in the dummy load even though it may have a protective coating. The ultimate destruction cycle was with vegetable oil where the resistor was destroyed in as little as one year. Frying tonight!
