Washington, March 10.-Allocation of 20 wave lengths among the various classes Of wireless telephony scnders and government control ot establishment Of all commercial wireless telephone transmitting sta tions are recommended by the three committees of the government radio conference made public today.
 The recommendation do not pro vide for government control of re- ceiying stations. which Secretary Hoover has said have increased to the hundreds of thousands in the last few months. Amateur trans hitting stations under the commit tees proposals would be given ex- elusive use of wave lengths from 150 to 200 metres and share with tech nical and training schools wave lengths of from 200 to 275 metres.
 Other recommendations are that wave lengths below 5000 metres should in a general way be reserved for radio telephone service, but that those wave lengths which have become fixed In service for telegra ph service within this range such as s.
 
 committee's report expresses Tthe ishope and expectation that tho radio telephone may ultimately Keep the whole range from zero to 5000 me- tres"
 The committee further urged that the time periods assigned to the dif- ferert transmitting stations for the various services be placed under the control of the commerce departments al he accorded the status Of a public ut.l ity.
 The recommendations. it was aa- nounced, have been transmitted to interested organizations and compan- ies for consideration, and the full conference will meet again in two or three weeks to formulate it's final report.
 Urge Law Amendment
 With respect to Legislation the committees urged that the radio laws be amended to give the secre- tary of commerce "adequate legal authority for the effective control of the establishment of all radio trans hitting stations except amateur, ex- perimental and government stations" and the operation of non-govern- mental transmitting stations.
 The present development of the art of wireless telephony the commit tees find, warrants the. separation of twenty wave bands. The committee recomm nded that priority first be given brosdcasting service and that broadcasting be divided into priori- ties in this rotation: Government educational and public, private broadcasting, including entertain ment. news, etc, and finally. toll broadcasting.
 In addition to the wave lengths of i50 and 275 metres for the amateurs additional wave lengths might be assigned to them for some opportun- ity in experimental work. The anna teurs, under the recommendations would arrange between themselves as to the division of their wave bands between different varieties of ana teur work.
