It's THAT Time of the Year!

Got a few spare dollars to support a worthwhile organization or two before 
the end of the year? 

Please think of these fine organizations ... THEY will thank you, YOU will be proud of 
your support of amateur radio, and YOU might derive a "benefit" at tax time in April.(*)
- AMSAT - The Radio Amateur Satellite Corporation

- ARISS - Amateur Radio on the International Space Station https://www.amsat.org/donations/ariss-donations/

Happiness ...

Clint Bradford
 

We all know someone who tries to make lives miserable for others. They love being the "man behind the curtain" and pretending to know it all - and believe themselves to be the only ones who can cure the universe's ills. They are just un-happy folks.

Educated? Maybe. But for some - they are just unsatisfied with their lives.

For years they quibble and belittle, making spectacles of themselves.

Before you un-friend them and move on ... pass this on to them. 


Re: Don’t Count AO-91 Out Yet!

David Spoelstra
 

Several other IMPORTANT items for AO-91:

1. If you have a nice, new, shiny IC-9700, please turn it down to 5 watts! That goes for everyone else too! I've been told by numerous satellite people that the high-power contacts sap the batteries.

2. If it's between 7am - midnight local and you can't hear anyone on AO-91, then something is wrong with your setup! AO-91 is *packed* during those times. I'm on fairly regularly from 9am - 2am EST and always make contacts on every pass. So please don't continuously call "cq satellite" because you don't hear anyone - you are talking on top of a lot of people trying to make contacts. *You* just can't hear them. There has been a rash of people calling 'cq satellite" on AO-91 during the past three weeks because their setup is wrong.

3. Use full-duplex! I used two Baofung UV-5Rs for a while. They cost $50 total. You need to use full-duplex so that you know your setup is correct. If you are calling "cq satellite" and you don't hear yourself, then you know your setup is wrong.

4. When your setup does work, please don't call "cq satellite". Just give your call and grid square. Like "N9KT EM69". If someone is out there, they'll call you back.

Re: Fox-1E Launch Window

Yes!


Launch Window for AMSAT’s RadFxSat-2 / Fox-1E Opens December 19th December 2, 2020

Virgin Orbit has announced that the launch window for their LauncherOne Launch Demo 2 mission opens on December 19th. This launch will carry AMSAT’s RadFxSat-2 / Fox-1E to orbit.

RadFxSat-2, like RadFxSat / Fox-1B, now AMSAT-OSCAR 91, is a partnership opportunity between Vanderbilt University and AMSAT and will carry a similar radiation effects experiment, studying new FinFET technology. RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a linear transponder “upgrade” to replace the standard FM transponder in Fox-1A through D. In addition, the uplink and downlink bands are reversed from the previous Fox satellites in a Mode V/u (J) configuration using a 2 meter uplink and 70 cm downlink. The downlink features a 1200 bps BPSK telemetry channel to carry the Vanderbilt science data in addition to a 30 kHz wide transponder for amateur radio use. Telemetry and experiment data can be decoded using FoxTelem version 1.09 or later. FoxTelem is available at: https://www.amsat.org/foxtelem-software-for-windows-mac-linux/.

Participation in telemetry collection by as many stations in as many parts of the world as possible is essential as AMSAT Engineering looks for successful startup and indications of the general health and function of the satellite as it begins to acclimate to space. AMSAT will send a commemorative 3D printed QSL card to the first station capturing telemetry from RadFxSat-2.
Uplink LSB 145.860 MHz through 145.890 MHz
Downlink USB 435.760 MHz through 435.790 MHz
1.2kbps BPSK telemetry 435.750 MHz

Launches on ELaNa XX – Virgin Orbit LauncherOne Launch Demo 2.

Re: Pi Projects

Thanks - I have ‘ACK’s site bookmarked - Was waiting for his magnificent setup file to get updated to the latest Raspberry Pi iOS release - but see he’s already updated for us!

There are some truly great hams out there - dedicated to their “niche” in this hobby.

Clint

PS I am as “Yaesu System Fusion” illiterate as can be. But I actually got on a local system this afternoon with my FT-70 - and the gentleman who came back knew me - and said I was responsible for him getting involved with satellites. And now he’s assisting me “dialing in” my ZumSpot settings ...

Gawd, gotta love this hobby!

I wondered that myself. However a pair of commercial eggbeaters is over 400 bucks. I can build a pair of mashers for about 20 bucks.

Anyone here using this type of antenna? I'm thinking of building a pair and I'd like to know what y'all think.
