I’ve put together a few links for those in your tech group who have an interest in ham satellites. Also attached is the current issue of the AMSAT Journal which you can share freely as they made it available to everyone this month as part of their COVID-19 response. (Go to amsat.org and click on the link for the free download)

SATPC32 is a great tracking program.

For those just starting out a good antenna can be the first big step to successfully operating ham satellites. Here’s a couple links to great portable sat antennas:

There was a question on tonight’s tech net about using scripts during a contest. Attached are the two scripts that I created for SSB contacts using W7FLO and W7L for Field Day. In the digital modes the scripts are put in macro form so that you click on a button and it plays the relevant part of the script. One example is:

The CW operators use similar scripts.

Any other questions, please let me know.

Notes:
1. make sure the frequency is clear before calling CQ. Listen, listen, then ask 3 times
2. General CQ— CQ, CQ, CQ <call sign>, <call sign>, <call sign>, CQ, CQ, Standing by or “BY”
3. Directed CQ— add in that you’re looking for a specific region, country, section, outside the USA, etc. to the CQ
4. Listen for enough time for someone to write your call sign down and comfortably give you a call back
5. Know some the prefixes for foreign call signs, as you are their DX
6. Have fun!

Wires X
We had about 10 people on the net tonight and I think that there are a lot of folks who, like me, don’t have a lot of experience listening or participating in nets. I have a few that I collected on this net to share with those who weren’t able to join us tonight.

Larry, K7GND, gave us a couple CW nets and one that meets in a “room” called the Quad Net Array. The two CW nets are:
Bob Net
06:30am 7day/week
3.558MHz (80 meters)

QRS (slow speed 13-15 wpm)
3.540 MHz
07.00pm 7days/week

Bond, K7BND, listens to the Marine Net and the Alaska Emergency net
I looked under Alaska on the ARRL Net Directory Search and found 16 nets:
