ARISS and Giving Tuesday
by ka3hdo＠gmail.com 26 Nov '18

26 Nov '18

All, Just a reminder that tomorrow, Nov. 27, is giving Tuesday. I hope some of you get out there and give to your favorite cause. I also hope AMSAT and ARISS are at the top of your lists. The following is on the top page of the ARISS web site. Take a look at: www.ariss.org <http://www.ariss.org> The donate button is there too. So please consider a donation to ARISS. It should also be noted that while folks are giving to their favorite causes tomorrow, the ARISS hardware team will be presenting to NASA the thermal modifications made to the power supply of the ARISS next-generation radio system If we get through this hurdle, our next step is flight hardware fabrication, flight testing and launch! Please wish the ARISS hardware team the best! Thanks for all your interest and support to ARISS! Ad Astra! 73, Frank Bauer, KA3HDO ARISS International Chair AMSAT V.P. for Human Spaceflight Programs ************** Tuesday, Nov. 27 is <http://www.givingtuesday.org/> #Giving Tuesday, when many people donate to a favorite cause. Gifts to ARISS on Tuesday or at any time of the year are a wonderful way make a difference to our youth, to our communities and to the amateur radio hobby. All ARISS donations via AMSAT (including Fundrazr) are tax deductible to the extent allowed by law. If donating directly to AMSAT, be sure to designate "ARISS" on your check, in the PayPal notes or in your letter. Our readers can consider doing the same thing John Carobine, WB8RFB, did -- here is his letter. I'm not one who considers myself influenced much by advertisements but I recently made a donation to AMSAT-NA to support the ARISS mission of bringing technology awareness to a whole new generation of young people because of one; namely, the Kenwood advertisement on the back page of the July 2018 edition of QST Magazine. I "connected" with it and it made me want to support this program in whatever capacity I can. In part, the ad stated "The ARISS mission is to provide and operate Amateur radio systems in space aboard the International Space Station, helping inspire, educate and engage youth and communities worldwide in science, technology, engineering and mathematics." The last 11 years of my working life were spent as an adjunct instructor of adult education in my local college's GED program. I taught some of those subjects. As I told my students "knowledge is power and power enables one to have many options." The mission statement struck a cord with me having worked in various capacities in each of those areas over the span of my entire working career. I spent twenty years in the U.S. Navy working in various meteorological, oceanographic, electronic and computer maintenance and management capacities. Those activities plus additional formal education opened future employment doors for me in the civilian sector for 30 additional years. Exposing school students via ARISS to the possibilities of careers in STEM is nothing short of positive. As stated so many times before, we never know what lesson, activity, or casual statement will open a person's mind and inspire them to greatness. As I celebrate 47 years in amateur radio, I encourage others to reflect upon what amateur radio has meant and done for them. I hope that you too will be inspired to "pay it forward" and help preserve and promote an avocation that has meant so much to all of us. John Carobine, WB8RFB Life Member Permission to post this letter, originally printed in December 2018 QST, was received from John Carobine, WB8RFB, and ARRL.

UHF amps
by Jim White 25 Nov '18

25 Nov '18

I'm looking for suggestions on UHF power amps. One of my stations uses a 10mw output SDR with a 2W gain block after it on TX. Right now I'm driving the 2W into a MIRAGE D26 to about 35W. I'd like to have about 100W. As I look at the various amateur power amps I'm not finding anything with 2W in and 100ish out. I could add some attenuation to the SDR/2W amp string and get the D26 output down to perhaps 20W to drive another power amp but that's not desirable because two amps in series creates a few problems. I can find Minicircuits gain blocks that would get me to perhaps 10W, in place of the 2W gain block, then drive something like a D1010 but those are a bit steep at >$1,000.... So any ideas on how to get the SDR 10mw output up to about 100W would be appreciated. Jim
