Tom, How is the AM sensitivity Low-VHF and up? Any AGC or other insummountable fixed settings that might make it a poor choice for RFI-hunting? Thanks - David KD4E Don, The VX-3R has an HF sensitivit
I can hear the airport beacons below the AM-BC band fine. I was wondering about the impact of other variables; resonance of the antenna, lightning arrestors, antenna tuner, rig ... That aside, how's

Joe, I didn't see the term "log periodic" on that page & saw reference only to mono or dual-band antennas whereas I'm used to seeing log periodics broadband e.g. 100-500MHz -- so I didn't zoom in. Th
Please define "long". Which number of elements on VHF is considered adequate? 3-el 4-el 5-el 6-el 7-el Thing is, an LPDA pattern can be quite wide, as is a short yagi's. You need a long yagi to pinpo
OK, good point. Is there any advantage to a simple yagi, quagi, quad, delta loop, or circular element beam - or will all perform about the same? Each form factor has an impact on convenience; e.g. we
