All-Wave and Short-Wave Receivers

THE number of commercial all-wave and short-wave receivers in use in New Zealand is increasing very rapidly. About twelve months ago there. were perhaps no more than four, but now there are at least ten different makes, many of which are a.c. operated. Of the electric models there are the "Witimate," the "Gulbransen," . the "Atwater-Kent," the "Philips," the _ "Silver Marshall" and -the "Pilot a,c Super Wasp." A full report of the "Ultimate" appeared a short time ago, and we are now testing a "Gulbransen" combination. This employs a super heterodyne adaptor, and, from "our preliminary tests, it would appear that this would be a very satisfactory set: AtwaterKent provide an adaptor for their ordinary sets. Of the battery models, the "Courier," "Ultimate," "Philips," "Mack’s Add-a-phone" ‘"Meniwave," "Pilot d.c. Super Wasp" are perhaps best known. Most of these are designed to operate economically from "A" cells.
