Programming Your Radio? Connect This Cable & Launch Chirp! #shorts
Connecting your radio to a computer is simple using the standard TRRS programming cable. Just plug the 3.5mm jack into your device, connect via USB, and launch Chirp software to manage your frequencies. Effortless radio customization starts here.

Vacuum Tubes Still Glow — Grayson KJ7UM on Thermatrons
Grayson Evans KJ7UM wrote the book on vacuum tube homebrew radio. Literally. His Hollow State Design book, now in its third edition, covers everything from the history and theory of vacuum tubes to building your own circuits from scratch. Along the way, he coined the term Thermatron as a better name for a technology that deserved one.
In this episode we talk about his path from Georgia Tech EE student to self-taught vacuum tube builder, why Thermatrons are more accessible than most hams think, how to get a high voltage supply for about $25 on Amazon, his glue-and-go construction method on copper clad board, and the simple QRP kits he sells to get beginners started without getting shocked.
Join us as we explore how you can get involved in portable radio, QRP, and more in this episode of the All Portable Discussion Zone (AP/DZ). Every aspect of portable operations is covered in this biweekly podcast, from news and gear to achievements, the workbench, contests, awards, and beyond.

How do antennas actually work? What makes an antenna resonant, how does it radiate RF energy, and why do factors like impedance, polarization, radiation patterns, and antenna height matter?
In this video, we break down the fundamentals of antenna theory and explain the principles that every amateur radio operator should understand.
We’ll explore:
– How antennas radiate: How alternating currents and electromagnetic fields produce radio waves.
– Resonance: What resonance really means and why it matters.
– Impedance and SWR: Understanding feedpoint impedance, impedance matching, and reflected power.
– Radiation patterns: How antennas distribute RF energy in different directions.
– Gain and directivity: What antenna gain actually represents and why it doesn’t create additional power.
-Polarization: Horizontal versus vertical polarization and why orientation matters.
-Antenna height and ground effects: How installation conditions influence antenna performance.
-Efficiency and losses: Where transmitted power goes and why a low SWR doesn’t necessarily mean an efficient antenna.
Whether you’re new to amateur radio or an experienced operator looking to strengthen your understanding of RF fundamentals, this discussion will help you make better decisions when selecting, building, installing, and evaluating antennas.
Understanding antenna theory is about more than getting a good SWR. It’s about understanding how effectively your antenna radiates energy and where that energy goes.

🎃 Get a Signature 9 with FREE WORLDWIDE SHIPPING this Halloween!
👉 Claim the deal here: https://dxcommander.com/product/free-shipping-signature-9/
You MUST use the special link above to get free shipping — the offer won’t apply through the normal Signature 9 listing.
Want a proper HF antenna without guy ropes taking over the garden? The DX Commander Signature 9 is a freestanding, multiband vertical covering 40–10 metres, with a tune available on 6 metres too.
Fancy working 80 metres? Replace the 30-metre element with a longer wire, run it up the pole and out towards a tree or suitable support. It doesn’t need to be a perfect inverted L — I’ve had great fun running 80-metre pile-ups with a similar arrangement in Cornwall.
✅ No guy ropes required
✅ Ground-post mounting
✅ Lift it off the post when you need to take it down
✅ Supplied with our latest grey spreader plates
✅ FREE shipping worldwide through the Halloween link
International orders may still attract import taxes, tariffs and courier handling fees. Free shipping covers delivery, not those charges.
