Segment 4 (Announcements and Feedback)

  • E-mail from James Blocker, KG5IOR
    • Russ, I am a long time Linux System Admin who has recently gotten into ham radio (KG5IOR) and discovered your pod cast. In fact I was listening to my first episode today #145 when you start talking about a subject that I've got a little bit of experience with. There is an open source project that will decode the Automatic Picture Transmissions (APT) to images call APTDEC https://atpdec.sourceforge.net/. In all honesty it does lack many of the features that WXtoIMG has, but it is very useful for people who like working on the CLI. Something else you might be interested in is a project on GITHUB called Doppler - https://github.com/cubehub/doppler. This project will take the IQ stream from an RTL-SDR dongle and using the TLE (Two Line Elements) data that can be obtained from https://www.celestrak.com/NORAD/elements/noaa.txt or https://www.space-track.org and shift the frequency of the IQ stream to adjust for the doppler shift that happens when the satellite passes over head. Two other software project that you might be interested in that are VERY closely related are GPredict - https://gpredict.oz9aec.net/. GPredict will download the TLE data and show a map and tell you the next time a satellite will be in range. The other software project is libgpredict. It is created by the same guy who wrote doppler and is just a C++ library for taking TLE data and calculating the next time satellites will be in range. Anyway I'm not sure how a simple email that was only supposed to be about APTDEC and it being open source had gotten to be this long, but if you have any questions about any of the software packages I've mentioned let me know and I'll do my best to help answer them. Thanks, James Blocker.

Segment 5 (Cheryl's Recipe Corner)

  • With fall upon us, I think apples. And, what better than to take advantage of the local apple crops than...
  • Apple Cake
    • 4 eggs
    • 2 (scant) cups sugar
    • 2 cups flour
    • 4 tsp baking powder
    • 1 cup chopped walnuts or pecans
    • 1 cup golden raisins (optional)
    • 3 tsp vanilla
    • 1 cup oil
    • 2 tsp cinnamon
    • 1/2 tsp ground ginger (or nutmeg)
    • 1 can apple pie filling, drained*
    • Directions: Preheat oven to 350°F degrees. Combine eggs, sugar, vanilla and oil. Add flour, baking powder, cinnamon and ginger (or nutmeg). Fold in apples, raisins and nuts. Turn into a greased and floured 9X13X2-inch pan for 1 hour or until done. Note: 2 cups fresh apples may be used instead of canned apple pie filling. Peel, chop and core apples, then dredge in sugar before using. Servings: 12.

  • Scott Pettigrew - N8VSI says:

    Does anyone know where plans can be found for a “Lollipop” node, as Frank talked about in this episode?

  • Gary Frerking says:

    It’s not really rocket surgery – a 5 gallon bucket as the base. The bucket holds the battery and is also filled with sand or cement. PVC pipe goes up from the bucket; serves as antenna mast. Antenna mounted on top, router and possibly other optional items (such as camera) mounted near top in a suitable box. See this slide show, I think slide 16 & 18 for a “visual”. http://w8mrc.com/docs/presentations/HSMM-MESH-Web.pdf
