Looking for some input on good rx below 500Khz. I am primarily one of those weirdos that listen to the static trying to pull out a few NDB beeps and DGPS beacons (and whatever else I run into down there) and hope to get my hands on something with good sensitivity down there. I currently use an altoids tin special to bump the range up to the 10mhz ham band but am now hoping to get a separate radio. I am looking at an R75 but figured I'd get some opinions first. None of my HF rigs include the freqs down there, but probably wouldn't excel there anyway. I'm not looking to break the bank, but want somewhat decent performance. Thoughts? Suggestions?
