Drake TR 7
Drake TR7 in Operation
The Drake TR-7 is a solid-state amateur band transceiver covering 160 through 10 meters. Modes include USB, LSB, CW, RTTY and AM. It provides receive coverage from 1.5 to 30 MHz without crystals or gaps. Superior receive performance is achieved by using 48 MHz IF Up Conversion approach. Enjoy true passband tuning to combat heavy QRM. The standard filter is 2.3 kHz SSB. Power input is 250 watts PEP SSB/CW.

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.
