Regency K Programmable Scanner

Regency has come a long way since the introduction of its Touch, a programmable VHF UHF scanner. The K100 was a distinct improvement, and the new K5G0 has even greater flexibility- The K50Q follows the styling ol its predecessors Two touch-pad clusters provide frequency entry, frequency banks, and commands. Frequency range of the K500 is identical to that of previous models 30-50, 144-17 . and 440-512 MHz FM, The 500 nomenclature refers to the 545 prepro grammed ROM channels. By pressing one of...

Whether * you're already serious about satellite communications, or considering the new Phase III worldwide DX opportunities for the first time, KLM has what you'll need. A prime example is our 420-450 MHz 18 element Circular Polarized antenna. Designed for optimized communications through OSCAR 9, the 420-450 18C puts the lid on flutter and multi-path fading. And, with it's typical KLM broadband response, the 18C also meets the critical k needs of DX'ers, ATV'ers,...

F did not intend this article to be one which extolled the well-known but seldom-used Bobtarl, but my accidental discovery that two elements worked so well made me realize that here is the answer to the problems of 40-meter phased verticals. Since the full 40-meter Bobtail takes more room than the average ham has available, and since the ground mounted verticals take such a large radial ground system, using only two of the verticals in the bobtailed Bobtail curtain seems the answer to a dream....
