Re: [Elecraft] Linear thoughts

Eric, That's easy, #1 requirement should be spectral purity at full smoke. So simply take the features and functions of the KPA500 and increase output to 1500W PEP. I'd not like to see Elecraft waste their time with an Spurious/IMD spec that only just pass the FCC requirements, it's about time

Re: [Elecraft] DC placement

It depends on what you want to measure. If you want to see the match the KAT500 gives you (should be very good when tuned), then put it between the KPA500 and the KAT500. On the other hand, if you want to see what the antenna itself is showing, then add the sensor on the output port of the

Absolutely. You would need an antenna connected to an audio transducer (speaker or 'phones) to hear it. (Perhaps one would call it a non-conversion receiver.) An audio amplifier helps, but you have to deal with the 120 Hz buzz caused by the 60 Hz power line fields all around. A high pass
