Made a carioid antenna, well known as a HB9CV antenna among ham radio. It is actually a dual fed dipole antenna with 90 degrees offset between the drivers and 90 degree delay line. Using a boatanchor R&S ZPV to measure the delay line. #antenna #rfgeek

Hung my Alpha Delta DX-CC Fan Dipole antenna today. 10-20-40-80 Meter bands. So far reached 13,500KM away into every continent on the globe. #AmateurRadio #RFgeek

The new cat collars have arrived 🐈 which turn out to be low power devices in the 70cm Ham Band (433MHz). They beacon a signal a bit like APRS which I’ll investigate using rtl_433. There may be some interesting hacks for happy cat tracking…(extending range etc) 😁 #rfgeek

Tak jsem si chtěl domů koupit meteo stanici a nemohl vybrat kterou (kvalita, podpora #linux, Lan,...). No, nakonec stačilo počkat, až si ji pořídí sousedi. 📡😊👍#sdr #rfgeek

Ever wonder why @850KOANewsroom is called the "Blowtorch of the West"? This is their nighttime coverage pattern. #RFgeek (Thanks to NF8M for the great site) https://t.co/TvoUcgrlpD
