.17 to .47 MHz is not shortwave, it is longwave if anything, as the broadcast band begins at .510, if I remember correctly. It is a different animal from the shortwave bands that begin at 1.7 MHz or so. You can hear aircraft beacons, ship beacons, and some other odd and strange stuff below the broadcast band. It is for direction finding, and there is little if anything of intrest there. Most radios don't cover this band, so I am a little concerned you might be mistaken about the frequency range.

it says 0.17 to o.41 MH on this kenwood comunications receiver very noisy but other bands ok is it a radio problel or outside noise

Dangit, I hit return and posted again. I would say outside noise. Tune around and see if you can get some stations with MCW Morse code identifiers, ususally two digits (the main one for Atlanta is 266 kHz, ID BR -... .-.) They are usually just a few Watts and only to be used close to the airport. Aircraft receivers also get the broadcast band, you can use some AM stations for hundreds of miles in the air and listen to the ball game, too. There is also a bunch of crud down there, dunno exactly what it is.

Submarine communication. High-powered LF and VLF will go through water and earth. Land based transmitters use antennas under ground. (This is not classified information). Signals are coded, and sound like 'noise'. Also, there used to be a band of frequencies around 170 Khz that could be used with less than 100 watts without a license from the FCC. (May not be allowed to use now.) Also, I have heard Spanish speaking stations between 470 and 510 Khz, and around 400 Khz on sensitive regenerative receivers, which I have verified by feeding the antenna to a deliberately mistuned IF stage in a superhet. I think there may be some relatively low powered European stations on this band also- ?? they may no longer be active?. EdM
