Understand. I did pick up the DL1, and check the readings. They were
along the lines of what I experienced with the MFJ. But I could not
read it at a higher power, as it is only a 20w dummy load. But it
jibed with what I was seeing. I will get further readings with it and
a voltmeter.
This is admittedly topic skew, but for non-critical occasional am listening,
it would be nice to have a much lower cost option than the $120 filters. A
cheap ceramic or 2-xtal filter, about 15Khz bw would have been a nice
addition to the K3, maybe even as a st'd component.
