The evolution of my Shack since March 2016

Rohde & Schwarz EK070 Receiver

The PLL synthesized VLF - HF all wave receiver Rohde & Schwarz EK070 has been introduced in 1979. It's digital frequency readout has an accuracy of 10 Hz. The R&S EK070 has been one of the earliest shortwave receivers with direct keypad frequency entry, thirty electronic memories and the possibility of beeing remote controlled by a computer or a secondary controller BG 170.

Here the description [930 KB] how to connect the Rohde & Schwarz EK070 with the built in V.24 serial board to the PC in order to control the EK070 with OmniRig and Pegasus from N4PY. Carl did a software upgrade to control the EK070 with his software Pegasus version v4.42D.

Here another Link with more information about the EK070 and a link to German Website.

AV-640 Antenna 6m-40m since September 2018

HyGain AV-640 Vertical Antenna 6m to 40m (September 2018)

Hy-Gains new AV-640 Patriot HF vertical is one of the best built and best performing (8 BAND 40/30/20/17/15/12/10/6) multiband vertical Antenna available today. Make full use of your sunspot cycle with the Patriots low angle signal. The AV-640 uses quarter wave stubs on 6, 10, 12, and 17 meters and efficient end loading coil and capacity hats on 15, 20, 30, 40 meters. Instead of typical lossy can traps, the AV-640 resonators are placed in parallel not in series. There are no radials on the ground needed!

Final installation and ready for operation with 1kW - no tuning anymore!

Many thanks to René HB9NBG and Carine HB9FZC for the proper installation of my new AV-640 vertical antenna :-) click on the picture to see the amazing video
