In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Re: [amsat-bb] Fwd: White House wants to eliminate WWV
by Roy Dean 06 Sep '18

06 Sep '18

I've been licensed for about 2 years. I'm not an ARRL member, nor do I have an ARRL handbook. I'm not trying to stir up muck here, I just asked a simple question. What benefit do we get from WWV? I certainly have had no cause to use it (at least knowingly) over the course of the last couple of years. Seriously, what am I missing out on? -Roy K3RLD > The K call implies that you have been licensed for a while. > Your ARRL handbook has information on what services WWV provides. > These include standard time, standard frequency and propagation > information.

Re: [amsat-bb] Fwd: White House wants to eliminate WWV
by Scott Medbury 05 Sep '18

05 Sep '18

For over 60 years, I have considered the function of WWV and WWVH to be vital and quite necessary. As youngster and before I owned a watch that did not set itself, I listened to WWV to know the exact time. I also listened to know of tropical happenings. As a shortwave listener, I knew when certain bands below 30kc (kHz) would allow communications. These are things that ALL licensed hams should know. 73 ...

Re Measuring VSWR at 2.4GHz

Hi Zach / Terry / Simone / Graham / Stefan. Thanks very much for the advice / offers and links. Hopefully there is a PA saving solution in there.

Complete Satellite Antenna System For Sale
by David Swanson 05 Sep '18

05 Sep '18

I've decided to part with my home station and go back to being a fully portable operator for the foreseeable future. So here's what I got: 145mhz Innovantenna 5 Element X-Pol 435mhz Innovantenna 10 Element X-Pol (Factory New, just unboxed, inventoried and repackaged). 2x Innovantenna 2m Balun 2x Innovantenna 70cm Balun 2x Comet 4160N Dupelxers 2x C2G N-Male to N-Male Barrel Connector 2x Tohtsu CX520D Relays, with Dissapation Capacitor Installed. 2x 12 Gauge Wires to Relays with Soldered Ends 4x Andrew CNT-400 Short Jumpers (2' to 4') with Amphenol N-Male Connectors for between Baluns and Relays. 2x DXE Basic Saddle Clamps for Mounting Box 1x DXE Heavy Duty Saddle Clamp for 145mhz X-Pol boom. $550 + Shipping (Guessing it will be about $75 anywhere in the lower 48, will get an exact quote if A few notes - the 145mhz X-Pol was outside for about 10 months at my QTH (Just long enough for me to get my 488 finished) as was an old 435mhz beam, but I damaged part of the 435mhz during disassembly, therefore I ordered replacement 435 metal and it is all factory new never exposed to the weather. All the relays and duplexers were inside weatherproof housings on the Mast and all in good working order. I also drilled holes for a heavy duty DXE saddle clamp on the 2m boom because I had some trouble with the factory saddle clamp slipping on my fiberglass cross beam. There's no slipping now. Here's a picture of everything all spread out on the shop floor: http://druidnetworks.com/xpol.jpg At this time I'm not interested in any trades, and I'm not interested in splitting what I have listed up. Shipping on this is gonna be kinda pricey so if you're anywhere within about 500 miles or so of EM34 I'm willing to meet halfway. Any questions or serious inquiries email me at dave(a)druidnetworks.com. 73! -Dave, KG5CCI
