Diy Cw Keyer

After iwo months of hightech digital communications, it seems ironic that this month we're about to build a CW keyer. But what the hell, thafs what we're going to do, This is such a simple construction project that it would be unfair to even consider il a weekender 1 Perhaps a rainy Sunday afternoon would be more realistic. The entire keyer is so simple thai construction is limited to two integrated circuits. The timing and logic are supplied by integrated circuits 4027 and 4011 CMOS. A printed...

Urban Antenna Restrictions

Moving to a new location provides a great opportunity to straighten out the amateur satellite antenna system and put everything together the Right Way, No more old coax, failing relays, noisy rotators, or rusted bolts. Significant improvements, more efficient operation and a clean installation always wait at the end of the rainbow. Ten years ago, before buying my previous home on the far outskirts of Houston, checked with the town s architectural committee about antenna restrictions, Their...
