KATSUMI EK-160 Electronic Keyer / Paddle


The EK160  Electronic Keyer / Paddle is a commercial grade electronic keyer with a precision dual paddle built in.

Terminals are provided for connecting a paddle and/or bug or straight key (to use the keyer as an oscillator and to buffer the keying of a transmitter via the relay).  The keyer itself will function in "bug" (semi-automatic) mode at the flip of the front panel switch.

Speed setting is done via a front-panel control which is calibrated in characters per minute (5cpm = 1wpm, approximately ).

The adjustable paddles are switch - reversable for left-handed operators, and the contact spacing is easily adjusted on the front panel.   Iambic keying features full dot and dash memories. The weighting ("code ratio" can be adjusted from 1:3 to about 1:4.  There's a built in monitor with volume control on the front panel and pitch control on the back,  and a jack for headphones or external speaker (8 Ohms, 300mW).

Built-in high-speed reed relay supports negative-keyed rigs  with up to 280VDC and 2A on the key line, or use JFET keying for transistor-keyed +V rigs and save wear and tear on the relay..

Specifications:
Speed range: 6-50wp,
Keying circuit:  reed relay or JFET
Power Source:  110VAC  o r 220VAC
Size/Weight:  9x4x2.5in,  2 Lbs,  12 Oz.

Sky Sat Communications of Montenegro & InnovAntennas


Sky Sat Communications of Montenegro appoints InnovAntennas Exclusive Distributor for its Advanced Contest Solutions Product Line in the North American and United Kingdom Markets
Sky Sat Communications, founded by internationally renown amateur radio contester Ranko Boca, 4O3A, today announced the appointment of InnovAntennas as exclusive distributor of its Advanced Contest Solutions line of ultra high performance Filters, Switches and Automation & Control Devices that ‘no serious shack should be without’ for the North American and United Kingdom markets with immediate effect.
The Sky Sat 4O3A product line is the result of many years of contest winning experience and development. The pitfalls of under performing mainstream products have been overcome to provide high-performing products giving serious contesters––and DXers––trouble-free functionality to ensure the points––and new DXCCs––keep racking up! In two short years Sky Sat’s customer base has expanded to include many of the world’s leading contesters and contest stations including 4O3A, OH8X, ES5TV, PY5EG, S51A, WX3B, YT3M, DR1A, LZ9W, LX8I, K3WW, UA3AB, S52X, CR2X, II9P, et al.
Sky Sat’s CEO Ranko Boca, 4O3A said “I have been looking for the right partners to expand Sky Sat’s reach into North America and the United Kingdom for some time and was delighted to discover that InnovAntennas, with operations on both sides of the Atlantic, could cover both markets. InnovAntennas fully understand the needs of contesters and DXers, the amateur radio world’s most demanding customers, and are well suited to provide sales and support for our products.”
InnovAntennas is now stocking and supporting the Sky Sat 4O3A filter products and will be making available the balance of the product line during the second half of 2012. Available immediately are the High Power 5-pole and 3-pole Monoband Band Pass Filters (Series S & Series L) for the HF contest bands: 80m, 40m, 20m, 15m and 10m, and the High Power HF Triplexer/Combiner. Stations using Tribander antennas to cover 20m, 15m and 10m can use the High Power HF Triplexer/Combiner in combination with Series S filters to operate simultaneously with a high level of isolation on all three bands with multiple transceivers sharing the same antenna – perfect for serious contest efforts from home, Field Day and DXpeditions. All 4O3A filters, including the Triplexer/Combiner, are rated for full legal power at high duty cycle modes such as RTTY.
InnovAntennas America co-founder & executive chairman William Hein said “InnovAntennas strives to sell only the absolute best, no compromise antennas and accessories and have found a kindred spirit in Ranko, 4O3A. My new personal contest station in Colorado is being designed around 4O3A-designed products in the shack and of course our own InnovAntennas products in the air. We look forward to a long, productive relationship with Sky Sat and can’t wait to see what comes next out of Ranko’s lab!”
About Sky Sat Communications
Ranko Boca, 4O3A, founded Sky Sat Communications, a producer of digital and analog transmitters for commercial TV and FM broadcasters as well as custom telecom products for a global market, in 1990.
Unsatisfied with the performance and quality of performance products made for hams, Boca and Sky Sat launched a Ham Radio Department in 2010. Boca (ex-YU6AD, YT6AA, YT6A) married his decades of hands on contest experience with the latest technology to create unique, ultra-high performance products designed and manufactured without comprise for the amateur radio world’s most demanding users: contesters and DXers.
About InnovAntennas
Justin Johnson, G0KSC, launched InnovAntennas, Ltd. in 2011 after his antenna designing hobby led to a flood of requests to “please make one for me” from amateur radio operators who recognized that Johnson’s designs outperformed anything they could buy from a store. InnovAntennas America, Inc. was launched in January 2012 by William Hein, AA7XT and is based in Glade Park, Colorado. The company’s antennas and accessories are available directly via InnovAntennas.us (for North America), InnovAntennas.com (for the rest of the world) and via a worldwide dealer network.

73

"The best number is 73. Why? 73 is the 21st prime number. Its mirror (37) is the 12th and its mirror (21) is the product of multiplying, 7 and 3. In binary, 73 is a palindrome, 1001001 which backwards is 1001001." Amateur Radio Operators often use the number 73 as an abbreviation for "best regards", typically when ending a QSO (a conversation with another Amateur Radio Operator).

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

  • 1 to 6 is BEST
  • 7 to 9 is OK
  • 11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.

SFI index [ HIGH is GOOD ]

  • 70 NOT GOOD
  • 80 GOOD
  • 90 BETTER
  • 100+ BEST

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.

K index [ LOW is GOOD ]

  • 0 or 1 is BEST
  • 2 is OK
  • 3 or more is BAD
  • 5 is VERY VERY BAD

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.

A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
