New toys arrived! WR90 / WG16 cal kit, metrology grade. I hope that it helps to build better LNA’s for 8.4 and 10GHz https://t.co/wvqtTExEh3
All the day in front the VNA! Calibrating homemade calkits and other standards for other hams.

Strange “stairs” received from a lot of european stations over 13kHz Some idea about this? #VLF #hamradio #hamr #swl https://t.co/6mOqNnJrRJ
Hack of a 20 years old 5v PCI GPIB card to use in a 3.3v PCI slot. Playing with hpdrive a emulator of old HP drives. https://t.co/ZiVsEZts9v
Comparing 4 different cal kits with the same DUT.
Be careful, test equipment can become a hobby in itself! True 😉 https://t.co/r5LkvGIn7X
New toy for the VNA arrived today 🙂
Looking for a HP 8510c users, do you have access to one? #hp #agilent #keysight https://t.co/Ov7iXuyAAu
Tnx @ea3hmj for the test! Really amazing 100km in 47GHz without visibile path #ghz_bands https://t.co/vIeZYfOdqW

First light of the 76GHz xverter, TX test. The Yaesu FT817 is sending CW at 144.5MHz as IF.

Building the new 76GHz xverter, the 47GHz in front to compare the feedhorn size. Tnx @ea3hmj for the fine milling. https://t.co/zNcBnvk7Xa
24GHz QSO succesful with EA5DOM and EA5JF in Monduber at 259km. Not bad for a marginal tropo condicions #ghz_bands https://t.co/xW07aacUyl
76GHz test with @ea3hmj. QSO to EA5JF & EA5DOM 47km over sea, EA record. Thanks for a great radio day! #ghz_bands https://t.co/g8ttsMe7O3
