Price Increase

It will probably come as no surprise at all that the 73 cover price will be going up wth the July issue. So will the subscript tion rate. It'll beS2.95 per copy I expect and a one year 'ate of 25 (US). You can stave off the higher prices If you get busy and extend your subscnotion for three years at the current rate of S45 (in the US). That would save you 30 over the next three years, unless it becomes necessary to put another increase in the interim. which is not at all unlikely, considering...

Gushing with confidence over the success of m new AFSK generator, the thought of marrying loe's Baudot generator to a CW IDer thrilled me. Sitting down with schematic and pencil in hand to discover what changes would be necessary, I discovered happily that a couple of inexpensive gates, a single transistor, and a few small parts would do the job just fine.

The Magic Of Ham Radio

Inductive Loop Receiver Service Manual

Under various caflsigns, Jerry Swank W8HXR has been heard on the ham bands since 1919. He has watched amateur radio grow from the days of Model A spark coils to an era of microprocessors and satellite communications. In The Magic of Ham Radio, Jerry gives his account of our hobby during the past six decades. W8HXR has often been where the action is. Jerry has responded to calls for help from earthquake-stricken Managua and tornado-ravaged Xenia. Antarctica, one of man's loneliest outposts, has...

L never thought I'd be excited over an electronic Ikeyer again. Like many other hams, t built a WB4VVF Accu-Keyer several years ago and was perfectly satisfied with it until a few months ago. The happy relationship with my old keyer was upset by the arrival of the Morse-Mauc, a remarkable little black box produced by Advanced Electronic Applications. Inc., of Lynnwcod WA. The MorseMatic has so many features that it's hard to know where to start. There are four basic modes of operation Keyer,...
