SDR Front End Protection and Spin Modulation Fading
by Mike N8MR 23 May '19

23 May '19

I have an SDRplay RSP1 that I’d like to use as a downlink receiver, along with an Arrow 146/437-10 antenna and Yaesu G-5400 az/el rotators. Uplink will be an Icom IC-7000. Using this setup, will the SDRplay need a Front End Protector to keep it from overloading? If so, which ones are recommended? Also, I am considering upgrading the antenna to an Alaskan Arrow. Is there a noticeable improvement in antenna performance and gain between the standard Arrow and the Alaskan? Would the improvement in gain also result in deeper fading during spin modulation? 73, Mike, N8MR

FT-817 Satellite Interface ARRL
by Rudi 23 May '19

23 May '19

Hello, In the past there was a Satellite Interface available via ARRL for the FT-817, this is no longer the case. If anyone has one and wants to sell it, I like to buy it. If anyone has the diagrams, or manual with the instructions and the parts, I would like a copy so I can see if I can make it myself. Thanks for reply. Rudi / ON7CL / KB8TAB

"New" LoTW items not showing up?
by Scott 22 May '19

22 May '19

Hello! Of course I was happy to see the announcement that PO-101, AISAT-1, & the FT4 mode had been added to TQSL. So, this morning I got caught up on the entries that I had not previously been able to log. Unfortunately, none of them are showing up in LoTW. I thought perhaps the system was backed up, but I just submitted a contact for an “old” satellite, and that showed up with a minute or two. Does anyone know if there’s a problem with the LoTW database, or am I just not doing something correctly? Thanks! -Scott, K4KDR

Re: [amsat-bb] nteers needed for AMSAT booth at Ham-Com 2019

Last week Mac Cody posted the question about volunteers for the AMSAT presence at Plano Texas Ham-Com on the 7th and 8th of June. Yes there will be AMSAT involvement. We have a table in the main hallway, right next to the National Weather Service. We will be doing demos and will have scheduled presentations. We always can use people help with any one of those activities. Please contact myself, or Keith Pugh W5IU for more information. Tom Schuessler, N5HYP EM12ms mailto:[email protected] Mac A. Cody mailto:amsat-bb%40amsat.org?Subject=Re%3A%20%5Bamsat-bb%5D%20Volunteers %20needed%20for%20AMSAT%20booth%20at%20Ham-Com%202019%3F&In-Reply-To=%3C9c74 6c3b-8202-9f14-d42d-da9948872e23%40att.net%3E ________________________________________ I see that there is an AMSAT booth at Ham-Com 2019 in Plano, Texas. Has there been a request sent out for volunteers to man the booth or conduct satellite demos? I am certainly willing to help out. I plan on being at Ham-Com both Friday afternoon and all day on Saturday. 73, Mac Cody / AE5PH

CAS4A FM Interference
by alex weimer 22 May '19

22 May '19

While trying to work CAS4A the FM stations in Mexico completely took over the satellite throughout the whole pass. I could hardly hear WA6RLR although he had a 5x7 signal. The FM stations were throughout the complete passband during the pass. Looks like this satellite will not be workable if this keeps up. JACK KC7MG DM42

Traveling with HT and Beam Antenna
by Roy Dean 21 May '19

21 May '19

Uh oh. https://www.rtl-sdr.com/spoofing-aircraft-instrument-landing-systems-with-a… Here's the interesting part: "They write that the attack could also be carried out from within the aircraft, but the requirements for a strong signal and thus large power amplifier and directional antenna would still be required, making the operation too suspicious to carry out onboard." --Roy K3RLD
