If anyone is looking for HF bands with an RTL-SDR Dongle, try the V4 version. https://www.amazon.com/RTL-SDR-Blog-RTL2832U-Software-Defined/dp/B0CD745394… This one has better performance and has built in Up-Converter. 73, Terry Osborne ZL2BAC On 23/04/2024 7:44 am, Clint Bradford via AMSAT-BB wrote: > Two items that have thoroughly enhanced my enjoyment of this hobby the > past few years: An RTL-SDR Dongle, and the Inovato HamClock System. > > And either will just set you back $50. > > The RTL-SDR dongle will turn your computer, phone or tablet into a > radio scanner/ham radio receiver that can receive nearly all RF > signals.

Two Inexpensive Shack Enhancements
by Clint Bradford 22 Apr '24

22 Apr '24

Two items that have thoroughly enhanced my enjoyment of this hobby the past few years: An RTL-SDR Dongle, and the Inovato HamClock System. And either will just set you back $50. The RTL-SDR dongle will turn your computer, phone or tablet into a radio scanner/ham radio receiver that can receive nearly all RF signals. And is compatible with Windows, Mac OS, Linux, and Android. Here is a non-affiliate link to a popular kit on Amazon - https://a.co/d/8F2nSQn And I think I've written about the Inovato HamClock setup before. For $50, The Inovato Quadra PC bundle features the fantastic HamClock by Elwood Downey. Gives you all the essentials you need to run HamClock (will always auto-update to the latest) on your 1080p or higher resolution TV or monitor. This kit INCLUDES the Quadra PC, HDMI cable, ham-friendly USB power adapter, custom stand, a quiet fan with a short cable, and a USB hub for a neat, small-footprint and cooler-running installation. Just add your own keyboard/mouse if you don't purchase their +$10 mini-keyboard. The Quadra PC that you receive also has more ham-related programs pre-installed. It's Debian/Linux XFCE - a "Pi-like" experience. But you do not need to know ANY programming skills to get up and running.

I have not used that portable device, I have the TYT TH9800, and I precisely use it to operate on FM satellites, its duplex mode is very useful, the TYT TH9800 also has the cross-band repeater option.

Can one use just a whip? Alan - now a SK - made a few. A slide from my sat show ...

I would second what Clint said. I've made several hundred contacts with a whip. I was lucky to make one contact in a pass. I built a tape-measure yagi and I can effortlessly make 4 to 5 contacts in a pass with it.

Support the CubeSat History Project
by Aaron Zucherman 22 Apr '24

22 Apr '24

Good day AMSAT community! We have an update for the Community on the progress of the CubeSat History Project! For those unfamiliar, Prof. Robert "Bob" Twiggs and a group of former students and colleagues are working on gathering and publishing a series of books on the history of the creation and adoption of the CubeSat. Take a look at the LinkedIn announcement here: https://lnkd.in/eNZgv6Tk If this sounds like something you'd be interested in supporting, please take a look at our GoFundMe page here: https://www.gofundme.com/f/cubesat-history-project The community's response has been amazing! Over a hundred interviews were conducted, and countless images and documents from the earliest days of the CubeSat were collected! The result is that we have accumulated one of the most comprehensive histories of the CubeSat, with many unique, never-before-told stories! Reach out if you are interested in sponsoring the project to get a signed copy and your organization's name in the book. Please email Dr. Aaron Zucherman at azucherman(a)gmail.com. As a bonus, please have a look at our book's cover art! [image: image.png] On behalf of Prof. Robert Twiggs and the entire team, Thank you for supporting our mission!

And be careful using longer/heavier antennas on your delicate SMA connector. Consider a adapter to make that SMA a BNC. I'd rather see you wear out a $15 adapter, then tear the center pin connection off the circuit board of your radio, requiring a radio replacement or a $60 repair job. High-quality SMA connectors are only rated at 3 to 500 connections, and lesser-expensive radios are not using high-quality SMA connectors.
