Longwave under water ???
Hiya...
Sort of off topic, but a radio question none the less. I read a few articles and saw a few space documentaries regarding a possible future space mission to Jupiter's moon Europa. The theory is that there is an ocean beneath the frozen surface. The idea of the possible mission is to send a probe that will melt through the surface ice that is thought to be about two miles and then, send a "hydro-bot" through the hole. The "hydro-bot" (a mini submersible probe) will swim around and send live pictures back up to the mother probe still on the surface. From what I read, it is to be wireless transmission. OK.. so... Here is the question.... I got to thinking, that if it is going to be wireless and underwater, it's probably going to use longwave to transmit. I've read countless times that long wave is used underwater by subs and underwater research. Then, I thought.... If you take a long wave receiver to the shore and stick an antenna/probe into the water, will you be able to pick up any underwater longwave beacons or hear anything that you coulden't with the antenna just a few feet above the water, but not in it ??? -- Respectfully, Michael Location: New Jersey Primary Receiver: R-75 with full Kiwa mods Antennas: G5RV, 200ft "Frankenstein" roof wire Additional Radios: KA-1101,KA-1102,PL-550, KA-989, Info-Mate 837, GE-SR III Westinghouse H-104 (seven tube) Web Site: http://md_dxing.tripod.com |
