Law Relating to Portables

ee ITH "the advent of summer very many listeners will be wishizg to purchase or construct portables to take with them on their holidays. Some may even desire to take their home receiver, and the problem naturally occurs as to what the position is with the Post and Telegraph Department. If the home receiver is taken out to act as a portable, all that is necessary is a statement to this effect to be lodged with the District Radio Inspector in any one of the four centres. Where a separate receiver is to be used and the home receiver is still uséd a separate license for the-period covered by the use of the portable must be obtained. Those who design their own- portables must make certain that they comply with the regulations of the Department. It must be shown that the receiver is not capable of causing interference with other teceivers; in other words, there must be proper and arlequate regeneration control. Users of portable receivers with frame antenna are particularly warned about connecting the aerial directly into the grid of the first valve, nmnless there is a fixed condenser in series with it. Violation of either of these two laws may mean cancellation of the license.
