Dear The Vega rocket was successfully launched. The satellites were separated.

Re: [amsat-bb] 3D printing and threaded inserts
by Curt Laumann 03 Sep '20

03 Sep '20

Hi Paul, Right! This 3D printing enables so many different projects, is relatively EASY and LOW COST !!! To share some of the salient points for those not too familiar with 3D printing: A good-quality printer can be had for $250 (Ender3 is a VERY popular printer) Parts the size of your fist cost about $1 to $2 (roughly speaking) As Paul noted, there are materials which nicely survive UV and heat. You could print PETG parts for outside, or in the heat of your car. Parts take between an hour and a day to print, depending on size, complexity and density. FreeCAD software is really, really a nice match to what we do in amateur radio. A couple of hams here in Tucson love it, and it is very nicely suited to making ham radio widgets :) Cura software (also free) is used to take the output of FreeCAD and create "gcode" which drives the 3D printer. The heat insert tool that Paul referred to in his previous email can be seen at the link below: https://www.amazon.com/dp/B078K72615/?coliid=I1K4DNMRZKIRXN&colid=2BL2OM2F3… As for material, I get filament made by eSun which prints very nicely. I use PLA+ for stuff indoors, and PETG for outdoor products. Fun Fact: I print 27 whistles in a batch (takes 23 hours), add split rings, and give them away as gifts. They're about a dime each. Another Fun Fact: "Thingiverse" contains 1000's of projects that can be printed. All of this information is well known to avid 3D printer people, and I'm sure others can chime in with their perspective / ideas / product recommendations. BOTTOM LINE: If you like to build stuff, ANY stuff, and are willing to learn a very minor amount of software, the payoff is very very high!

3D printing and threaded inserts

Hi All, To support my interest in building amateur radio equipment I recently dove into 3D printing. I'm sure many are aware of the technique below, but still others might find it interesting. *You can easily install threaded brass inserts into 3D printed parts, making them very robust and useful.* Feel free to view the PDF file at the link below for a brief introduction to this technique.

DELAWARE CONTACT?
by john＠papays.com 03 Sep '20

03 Sep '20

Several are asking about a Delaware contact. DE has always been rare on satellites. It was one of the last I needed for WAS more than a decade ago. The most recent op that I am aware of was WA3X. He has no email in qrz and hasn't uploaded to LOTW in about a year. N8HM operated from there as W3ZM/3 in October 2019. Maybe Paul could be persuaded to take the train up there and satisfy the demand for Delaware? 73, John K8YSE

Re: [amsat-bb] Just wondering. Are any of the modules on curently flying Fox Sats opensource?
by Bill Gaylord 02 Sep '20

Thank you. Anyone know what licensing that documentation would be under? If any.

ISS FM repeater
by Jean Marc Momple 02 Sep '20

02 Sep '20

Dear All, Just to let you know that Patrice (3B8FA) ad myself did superb QSO via the iSS FM repeater just a few minutes ago. Working fine 59+ both ways on V/U (145.990/437.800 MHz), really nice to have the ISS repeater back on air. 73 Jean Marc (3B8DU)

Re: [amsat-bb] Vega rocket (VV16) launch expected 2nd september : 3 Satellites with hamradio payload
by Daniel Schultz 02 Sep '20

02 Sep '20

According to the IARU website description, "AMICal Sat is an educational mission which has been developed by UGA-CSUG and MSU-SINP during 30 month. It involved 50 students of different level and specialties." One of the reasons that amateur radio still exists is that we can educate the next generation of students, and AMICal Sat seems to fulfill that mission. If it was a commercial or government mission or an academic mission without substantial student involvement, then Part 5 or whatever the European equivalent is would be more appropriate, but to grow the next generation of space scientists and satellite engineers it would seem to be a legitimate use of amateur radio frequencies.

DE activation
by Russ Kinner 02 Sep '20

02 Sep '20

I would think some Philadelphia based Sat. Ops. might be able to get the state on air. I hope to be in the general area in late November and might make a day trip to DE. Not sure about the trip yet but that seems to be a demand I could fill. Rusty, WA8ZID
