LNA + SAW filter limiter question
by Hans BX2ABT 13 Aug '18

13 Aug '18

I'm still experimenting with PGA103+ LNAs. I want to add a SAW filter (70 cm) behind the LNA, but I see in some designs that in order to protect the filter they use a diode limiter, e.g. the SKY16602-632LF. That one uses an MLP package which you can only reflow, and don't have that possibility. The SAW filter has a max input of 0 dBm (1 mW). Can anybody tell me how to choose diodes in order make an anti-parallel diode limiter myself? Thanks for helping an RF n00b. 73 de Hans BX2ABT

G-5400B Rotor problem
by Richard Lawn 13 Aug '18

13 Aug '18

I could use some help trouble shooting my only G5400B AZ rotor. I rebuilt the EL rotor years ago. I replaced the entire system with a 5000 at home and now use this old 5400 at the summer place. The AZ just quite working. I suspect it's a bad pot but could use some guideance in troubleshooting as I don't have access to my notes from the EL rebuild years ago. What measurements should I see at the controller interface? Good thing we are going home in a week! Rick, W2JAZ

In 2002/2003 the school was refurbished and in 2008 the rooms for natural sciences and information science were modernized. At the moment the school has 670 students and 60 teachers. Pupils are taught in two different profiles, the advanced scientific and the advanced linguistic (teaching a third foreign language) profiles. English is the first foreign language and students can then choose Latin, French or Russian. In grade 8 the scientific profile teaches a lot of different fields: optics, health, about the earth´s atmosphere or water. In grade 9 it comes to learning about light, colors, communication and issues about the earth. In grade 10 pupils are taught about measurements, different operations and regulations, bionics and astronomy. As the school is a secondary school with focus on sciences and languages it is possible to integrate all classes of those grades into activities concerning contacts to the ISS: Students will broaden their horizons and acquire more knowledge during the preparations and the actual contact with the ISS: Our schools offers a variety of full-day-provision in different fields of sciences, such as a course for achieving a HAM radio license, construction of electronic circuits in the area of telecommunication and networks, meteorology, aerology, climatology, sciences about earth and space, radio astronomy and electronics, sensor technology, microcontrollers and robotics, esp. opening and operating an amateur radio club for short wave and VHF/UHF and basics of the manufacturing of electronic assemblies.

W3XO - the rest of the story.
by Arthur Feller, W4ART 12 Aug '18

12 Aug '18

Our dear friend, Bill Tynan, put one of the earliest (perhaps the first?) FM stereo stations on the air as an experimental station. It’s call sign? W3XO. (The station originally licensed as W3XO later was licensed in regular FM broadcasting service as WGMS [Washington’s Good Music Station].) When the experimental station call sign block containing W3XO was transferred from experimental stations and became assignable to amateur stations, Bill applied for and was granted W3XO for his amateur station. Bill: you were one of a kind and we miss you dearly. Thanks for being a teacher, colleague, and friend for so many years. 73, art…..
