2M RX preamp for sale
by GEO Badger 07 May '19

07 May '19

MiniKits.com.au 2m 144MHz VHF RX/TX Preamplifier This product is ideal for use with the Icom Multimode VHF transceivers including the IC-275, IC-820/821, IC-910H and IC9100 that have a PREAMP enable switch to supply +12vdc out of the antenna connector in RX mode. Transceivers without this function will require an external bias tee like the Mini-Kits EME168-2-70 to supply DC power up the coaxial cable. When using a high power RF amplifier up to 500 Watts, additional sequencing will be required to protect the pre-amplifier from damage. The Mini-Kits EME166 Sequencer can be adapted to be used for correct sequence timing of the RX to TX changeover. This unit is peaked for 145.800 MHz and mounted in a Nickel sprayed GME enclosure. It was used once for an ISS contact. $100.00 USD OBO. Buyer pays S&H. Specifications Frequency Range:Band Pass: 140 to 150MHz (BW 10MHz @ 1dB)Band Rejection: Typically 40dB @ 50MHz, 60dB @ 430MHz Gain Adjustable: Typically +18dB Max, 10dB Min @ 145MHz Noise Figure: 0.8dB ( Typically <0.7dB @ 145MHz)Through Loss: 0.05dB @ 145MHz (Bypass Mode)RF Power Handling: 100W CW (Un-Sequenced ) 500W PEP (Sequenced)Minimum RF Input: +20dBm (100mW) To activate the RF sensing circuitOperating Voltage: +11 to 15vdc (+12vdc @ 150mA Recommended)Board Size: 80mm L x 84mm W x 25mm H (with BNC connectors) --- Ciao baby, catch you on the flip side.

FCD pro + issue

My fun cube dongle pro + will not receive any single. It appears like it lost its LNA. Is this a common issue? It also causes a reboot when first plugged into the USB connector. nick Cell 337 258 2527 Helping UL become a world Class Engineering and Educational School Disagree I Learn

W0WCS demo on AO-91 - 1704-1716 Z 7 May
by Randy Shirbroun 07 May '19

07 May '19

Greetings, I will be doing a demonstration at my daughter’s school tomorrow (Tuesday, 7 May) on the mid-day pass of AO-91 – AOS 1704 Z during the kids’ lunch break. I’ll be operating as W0WCS, the school club’s call sign and the grid is EN23. It’s not a rare grid – I’ve been pretty active from here with my own call since I got started on the birds in October, but W0WCS has never been on the satellites before, just HF. Hopefully we can get several QSOs to show the kids the magic of satellite communication! We will confirm by old-fashioned QSL cards as well as LotW. Thanks and 73, Randy, ND0C

International Space Station Astronauts are Calling CQ Students ARISS-US program’s education proposal window is open April 1 - May 15, 2019 March 24, 2019: The Amateur Radio on the International Space Station (ARISS) program is seeking proposals beginning April 1, 2019, from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1, 2020 and June 30, 2020. Each year, ARISS provides tens of thousands of students with learning opportunities about space technologies, communications, and much more through the exploration of Amateur Radio and space. The ARISS program connects students to astronauts on the ISS through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, other Amateur Radio global organizations and the worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering, and mathematics (STEM) and in Amateur Radio. Educators report regularly that student participation in the ARISS program stimulates interest in STEM subjects and STEM careers. One educator wrote, “Many of the middle school students who took part in and attended the ARISS contact have selected science courses in high school as a result of that contact.” Educators are setting up ham radio clubs in schools and learning centers because of students’ interest. ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and other STEM subjects. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for a once-in-a-lifetime opportunity for students. The proposal window opens April 1, 2019 and the proposal deadline is May 15, 2019. For proposal guidelines and forms and more details, go to: http://ariss-proposal-webinar-spring-2019.eventbrite.com Proposal webinars for guidance and getting questions answered will be offered April 11, 2019 at 7 pm Eastern Time and April 16, 2019 at 9 pm Eastern Time.

Reference the recent discussion on omni satellite antennas, I've used for years a Ringo Range II. Works for most passes. Made many contacts with ISS & could hear AO-40 at apogee when it was working. -73 Armando N8IGJ

Hi, I've tried to work a good pass of CAS-4B over Europe few minutes ago: calling cq for most of passes and listening over the bandwidth I got no responses and I haven't heard anyone... Just a case or the satellite is almost unused? 73, Lapo IK5NAX
