WHAT WILL YOUR NEW RIG BE LIKE? Read 73 and Find Out The magic of digital electronics is coming to ham gear... and you'll be able to read about these developments in 73. The re probably will be more changes in ham equipment in the next few years than ever before in history . You'll see these cha nges coming in 73, where you'll read about the experiments and pioneering. 73 has more articles than any othe r ham magazine...often more than all the others combined. When sideband got started, it was moved along by the many pioneering articles in 73. In the 60s it was solid state, with several times as many articles on the subject tha n in all the other magazines combined. When repeaters and FM got going about ten years ago there were over five times as many articles on the subject published in 73 as in all othe r ha m magazines combined...and you ca n see what changes that brought to hamming. Now we're looking at exciting developments suc h as narrow band sideband for repeaters . .. which might give us six times as many repeaters in our present bands. We're looking at automatic identification systems which may make it possible for us to read out the call letters of any station tuned in ...and even the development of selftuning receivers. Will stereo double sideband techniq ues make it possible to have up to 30 times as many sta tions within a given HF band as is now possible? Hams will be experimenting and reporting on these developments in 73. 73 is an encyclopedia of hamming . . . present and future...and just a bit of the past, too. Without the endless fillers on sta tion activities and club news, 73 is able to publish far more information... valuable information... on ha mmi ng and ham eq uipment. You mayor may not be a pioneer, but you certainly will want to keep up with what is happening and what the new rigs are going to be like. And, frankly, your support of 73 is needed to keep this type of information coming. ---------------------------- Yl@@2l bill me f()( 1year 01 73 Magazine at $2500 31486 Name _ Address _ _________ State. --"p lip _ Conodion 527/ 1yeo 0t't0I.
