WASHlNGION, May lo.-NOC uuJii midsummer will the governments most distant experiment in radio tele' phony be known. Far off on the gov. ernment's two most isolated light houses, namely, those on Cape Sarichef and Scotch Cap at the entrance to Unimak Pass in the Aleutian Islands each manned by a little group of keepers, there are two radio telephone receiving devices which were installed last year. For 10 months these TWO lighthouses have been shut off from the world, no vessel having landed there and neither station having any method of transmitting messages.
 How have the two receiving sets worked? How much of the great vol ume of broadcast telephone messages sent out in recent months has reached them? Have the keepers been able to keep in touch through these instru- ments with what is going on in the world? What will the results of the experiment show in regard to the dis tances travelled by radio telephone messages?
 SETS INSTALLED LAST YEAR
 By cooperation with the Navy, these radio telephone receiving sets were installed last year by the light house tender Cedar. She will make her annual visit to Scotch Cap and Cape Sarichef in late June or early July, but until then no news will come from the two stations.
 These experiments are in line with others that are being conducted by the lighthouse service, with a view to providing better living conditions for members of the service whose employ ment isolates them, and also to aid in navigation.
 Perhaps the newest things in radio as an aid to shipping is the installa- nal apparatus used continuously dur ing foggy weather to furnish accu- rate bearings to ships possessing the radio compass. Three such radio fog signal stations were established a year ago in the vicinity of New York harbor. Last week the first one was established. on the Pacific Coast on the San Francisco lightship.
 It is the intention of the Lighthouse Service, as speedily as possible, to equip the lightship on Swftsure Bank at the entrance to the Strait of Juan de Fuca, with this system, and like wise to equip the lightship at the en- trance to the Columbia River and the one near San Pedro, in California, in a similar manner
 The apparatus is an automatic radio telegraph sending apparatus operat- ed by clock work, sending at brief in- tervals the international code for sig nal on a 1,000-meter wave length The radio compass installation, now being placed on an ever increasing num- Der of ships, catches this signal and from it can be ascertained the direc- tion from which it proceeds, Ordi- nary fog signals, such as sirens and bells, never have been able to make known to a ship their exact direction from that vessel The radio direction in connecticut with the radio com- pass installation makes direction cer- tain.
 The first three stations on the At 1antic have proven so successful that the Lighthouse Service proposes to ex- tend the service to all coasts as ra- pidly as it's funds will permit.
 CAN LOCATE HIS SHIP
 ''The most valuable use of the radio fog signal" says the Lighthouse Ser vice of the Department of Commerce, twill probably be as leading mark, as, for example, to enable vessel to make a lightship anchored in the approach to a harbor or to pass out side of a lightship anchored to guard against dangers off the coast The navigator will also be able, as in navi- gation using visible objects, to locate his ship by cross-bearings on two or more radio stations or by repeated
