  • Understanding the Cavity Duplexer
    i THE CAVITY DUPLEXER John E Portune W6NBC [email protected] rev 2019 NOTE FROM AUTHOR This book was written several years ago and based on hardware-store copper water pipe as the source of home-brew duplexer construction materials. Later I began making from spun-aluminum commercial cake pans. Both require no welding. Unfortunately the price of copper is today much higher. Cake pans, however, are still reasonably priced, readily available and very acceptable as the basis especially for VHF cavities. Because of maximum cavity size limit, copper water pipe may still be indicated for UHF and above. In any case, how a duplexer operates is basic physics. No matter what the material, or whether the duplexer is commercial or home brew, the principles herein are universal to duplexer construction, modification and tuning. This book, however, is not finished. Repeater building is no longer my primary interest in ham radio. Some subjects could be added. But as it contains the essentials, I have placed on the internet incomplete. If you reproduce it, be so kind as to give proper author’s credits. W6NBC January 2019 . ii CHAPTER OUTLINE 1. The Mysterious Duplexer • The black box everybody uses but nobody understands • Keys to understanding it • This is not a cookbook 2. Let’s Make a Cavity • Home-brew 2M aluminum cavity • Example for the entire book • The best way to learn 3. Cavities • Mechanical and electrical properties of cavities • Basic structure of a duplexer • Why use cavities • Getting energy in and out: loops, probes, taps and ports • Three cavity types: Bp, Br, Bp/Br • Creating the other types • Helical resonators for 6M and 10M duplexers 4.

INTERFERENCE FROM RADIO TRANSMITTERS A Guide for Radio Operators This brochure is primarily for amateur and General Radio Service (GRS, commonly known as CB) radio operators. It provides basic information to help you install and maintain your station so you get the best performance and the most enjoyment from it. You will learn how to identify the causes of radio interference in nearby electronic equipment, and how to fix the problem. What type of equipment can be affected by radio interference? Both radio and non-radio devices can be adversely affected by radio signals. Radio devices include AM and FM radios, televisions, cordless telephones and wireless intercoms. Non-radio electronic equipment includes stereo audio systems, wired telephones and regular wired intercoms. All of this equipment can be disturbed by radio signals. What can cause radio interference? Interference usually occurs when radio transmitters and electronic equipment are operated within close range of each other. Interference is caused by: ■ incorrectly installed radio transmitting equipment; ■ an intense radio signal from a nearby transmitter; ■ unwanted signals (called spurious radiation) generated by the transmitting equipment; and ■ not enough shielding or filtering in the electronic equipment to prevent it from picking up unwanted signals. What can you do? 1.

  • Digiton Systems
    RESULTS OF THE DRM SIMULCAST FIELD TRIAL IN FM BAND IN THE RUSSIAN FEDERATION June to December 2019 Sergei Sokolov Sergei Myshyanov Digiton Systems Version 3, 2020-12-07 0. Abstract Digiton Systems carried out a high-power field trial of the DRM system in DRM Simulcast mode by order of the Russian Television and Radio Broadcasting Network (RTRN) in the FM band in the Saint-Petersburg city, in the Russian Federation during June to December 2019. The DRM Consortium members RFmondial GmbH and Fraunhofer IIS contributed their expertise to the trial to enable the system to be tested in a real commercial environment with a wide variety of reception conditions. RTRN provided financing for the trial. Digiton Systems provided equipment, project management and measuring effort for the trial. Triada TV provided the transmitter. European Media Group (EMG) company and GPM Radio company allowed to launch a digital DRM signal between their FM radio stations Studio 21 at 95.5 MHz and Comedy Radio at 95.9 MHz. Radio Studio 21 is a part of EMG and Comedy Radio is a part of GMP Radio. During the trial the existing transmitter infrastructure was used, without any changes in other broadcasted stations. The DRM signal was added to the combiner infrastructure, already combining more than a dozen analogue FM services onto a single antenna. This document describes the trial and results. Additional key words: DRM, Digital Radio Mondiale, FM-band, VHF band-II, DRM-FM, DRM Simulcast, FM Combiner 2 1. Location and environment for the trial The trial was conducted in the Northwest region of Russian Federation from the Leningrad radio and television broadcasting center located just to the center of the city of Saint- Petersburg.

  • Chapter 1 Background of the Project
    CHAPTER 1 BACKGROUND OF THE PROJECT CHAPTER 1 BACKGROUND OF THE PROJECT Currently, the radio transmitting station of MRTV is obliged to operate the transmitter at about half load of their capacities. This is due to such backgrounds as superannuation of equipments, shortage of spare parts, and increase of operation and maintenance cost. As the result, the broadcasting service area has contracted quickly each year (For the current service area, refer to Appendix-6(4) “Estimation of Project Effects”). Especially, transmission to the remote area cannot be fully performed in satisfactory and the means of information distribution towards the nomads is being lost. In order to cope with such situation, the Government of Mongolia selected three (3) stations (Ulaanbaatar, Altai, and Murun) among the existing seven (7) radio transmitting stations as for the Project objective location. The Government of Mongolia expects to restore the ratio of service area to the whole country up to 93% by installing a new 50kW transmitting system to Ulaanbaatar Transmitting Station, and 10kW transmitting system to Altai and Murun Transmitting Stations. In order to procure and install the above-mentioned equipments, the Government of Mongolia requested the Government of Japan for the assistance through Japanese Grant Aid. 1 - 1 CHAPTER 2 CONTENTS OF THE PROJECT CHAPTER 2 CONTENTS OF THE PROJECT 2-1 Basic Concept of the Project At the existing radio transmitting stations, some transmitters have been forced to stop operation due to technical failures, and, in other cases, superannuation of transmitters are advancing near the life limit of the transmitters. Furthermore, it was obliged to reduce the power output to nearly half of normal operation due to shortage of the spare parts and increase of operation and maintenance cost.

  • The HEATHKIT HN-31 CANTENNA
    NOTES on the HEATHKIT HN-31 CANTENNA HISTORY CONSTRUCTION ALL ABOUT THE RESISTOR SOURCES of SUPPLY OIL and HEAT PROPERTIES PERFORMANCE MEASUREMENTS by John White VA7JW FEBRUARY 2012 © Revision 1 NOTES on the HEATHKIT HN-31 CANTENNA HISTORY The Heathkit HN-31 sold between 1961 and 1983 for $9.95 as a 50 ohm dummy load without cooling oil; that was not included! The task of sourcing the appropriate oil fell to the buyer to purchase. Chuck Pensions book1 estimates that sales of the HN-31 were in the order of 200,000 units between 1961 and 1972. He further states that “The Cantenna RF Load is undeniably the longest running, most successful product Heath ever made”. One might have to agree since the MFJ-250 and Vectronic’s ALD-1500 are of a similar design and are still offered today. The author purchased the HN-31 model in 1968. The oil used is Heathkit recommended white mineral oil purchased from a pharmacy and is of medicinal / food grade quality. The other oil option is transformer oil, but it is more difficult to source. The dummy load has been used for many years and remains in apparent excellent condition. The resistance measures 49.4 ohms DC, the oil is visually clear, there is no evidence of contamination by water or rust or any other particulate matter, and the paint pail is mechanically sound. Figure 1 HN-31 Manual Excerpts dated 11 / 26 / 65 Reference 1 at End of Article HEATHKIT HN-31 INTERNAL CONSTRUCTION For those unfamiliar with the construction of the HN-31, some of the manual assembly diagrams are reproduced here.
