Amateur Television Network Amateur Television Network Microwave Band Use in Arizona, California & Nevada Background: Arizona Link Map Amateur Television Network (ATN) is a group of amateur television clubs (chapters) in many of the states within the United States. Most chapters have repeaters, many of them are linked via microwave. Most repeaters have an input or output within the microwave bands using both analog and digital modes. We have chapters in the following states: Alabama, Arizona, California (a north and a south chapter), Delaware, Florida, Georgia. Illi - nois, Indiana, Kentucky, Missouri, Nevada, New Mexico and Ohio. Most of our chapters support public service to California - Nevada Link Map provide pictures during drills, disaster and large public events where crowd control is important to public safety officials. UHF and Microwave band usage: 70 cm, 33 cm, 23 cm, 13 cm, 9 cm, and 5 cm. Linking is primarily in the 13 cm, 9cm bands and 5 cm bands. VSB (filtered AM) analog and DVB-T digital are the modes used as repeater inputs and outputs in the 70 cm, 33 cm and 23 cm bands and FM used in the 23 cm and higher bands. Most linking uses FM mode allowing up to 600 line resolution and no latency. Our largest linked repeater system is in the Ord Mt. Link Equipment southwestern states with seven repeaters linked in Southern California and Nevada and Arizona with three linked ATV repeaters. Ari - zona is currently building their microwave sys - tem towards California to joint the Notice the California- frequency Nevada system. 23 &13 cm 10’ Link Dish (see link maps on to Las Vegas the right column) The image in the monitor is from Santiago Peak’s 5910 MHz FM output (omni) received at 5 cm Ord Mt.

  • Planning a Digital-ATV Station for DVB-S
    Planning a Digital-ATV Station for DVB-S Ken Konechy – W6HHC Orange County Amateur Radio Club Orange County, CA [email protected] Robbie Robinson – KB6CJZ Orange County Amateur Radio Club Orange County, CA [email protected] Abstract Most ham radio Amateur Television (ATV) stations and repeaters in use today still utilize analog technology. The purpose of this paper is to explain Digital-ATV (DATV) to other hams, with the hope that it might make the transition from analog-ATV to Digital-ATV a little more straightforward. The paper begins with a review and comparison of various commercial DTV standards that are in use around the world. A top-down design methodology session is then conducted to sort through a number of design alternatives to plan a DATV station. The planning session chooses the DVB-S standard for DATV over the competing United States- based ATSC standard. The paper concludes by describing the Forward-Error-Correction factors and Symbol-Rate factors that determine the RF bandwidth for a DVB-S DATV station. Key Words DATV Digital-ATV DVB-S ATSC QPSK 8-VSB FEC Symbol-Rates 1 - Introduction to DATV For several years, Robbie and I have listened to some interesting ham conversations about “...we hams should change analog ATV over to Digital-ATV (aka DATV) to keep up with technology...”. While the goal seemed simple, the topic was very complex and not easy to grasp. We found that there really was no simple place to go...like a “one-stop-shop” for DATV information, especially here in the United States where ATSC is a standard to be carefully considered.

  • How to Receive Amateur Digital, DVB-T Television Signals Jim Andrews, KH6HTV
    AN-21b Receive DTV.doc (2/28/2016) p. 1 of 9 Application Note AN-21b AN-21 issued January, 2015 - deleted Major "B" Revision Feb, 2016 How to Receive Amateur Digital, DVB-T Television Signals Jim Andrews, KH6HTV The fundamental question is "How can I receive amateur DTV signals ?" The commercial TV broadcast industry began a transition from analog TV to digital TV (DTV) starting in the mid 90s. Several different, DTV systems were developed for different applications, such as over the air terrestrial broadcast, satellite broadcast and cable distribution. Each system had it's unique propagation characteristics and as a result, it's coding implementation. For amateur DTV, the system adopted should be optimized for terrestrial propagation where "multi-path" is always an issue. TV signals received from satellites, or directly over a CATV network are not subject to multi-path. Thus such DTV systems are less suitable for amateur DTV. The DTV system adopted by Boulder, Colorado and other Colorado Front Range radio amateurs is called DVB-T, or Digital Video Broadcast - Terrestrial. It is NOT the ATSC (8-VSB) system used in the USA for commercial TV broadcast over the air, nor for transmission in cable TV (CATV). It is the system developed in Europe and used by most of the rest of the world for broadcast DTV. Thus, in the USA, you can NOT use directly your home TV receiver to receive DVB-T. The reasons, we have adopted a European standard rather than an American standard are primarily based upon cost and availability of transmitting equipment and also on the superior multi-path performance of DVB-T over ATSC.
