Datong Active Antenna Model Ad370
Hello, I use the RSP2pro with a Diskone on Port B and an active antenna (DX10) on Port HiZ and Port A. For HiZ I use a homebrew transformer 6:26 wdg on a BN73-202 binocular core. Port A of the RSP2pro and the input of the transformer are connected to the DX10 (behind the Bias-T) by a simple resistive splitter (homemade, 4 Ports, 10dB attenuation port/port). Additionally there is a 10dB attenuator in front of Port A. The DX10 is fed by a Bias-T which separates the HF from the DC.
The Bias-T isolates the 12V DC by 470nF/47pF capacitor in parallel. An inductor isolates the HF. This works on HiZ from 10kHz to 30MHZ, on Port A from 100kHz ton 50MHz.

WUN EQUIPMENT SURVEY. by Ary Boender Almost 400 (33%) of our members have supplied a list of their equipment in the recent past. As promised I have compiled a list of receivers, decoders, and antennae as used by these WUNners. As antennae and other equipment ('various') were not included in the 'questionnaire' in the past, I have only info from 100 dxers about the subject. Thanks to everyone who has sent info for the survey.
You have a real nice collection of equipment in your shacks, that's for sure. I came across brands and types that I never saw before, amongst them a number of vintage machines. Looking at the receivers, we see that AOR, Icom, DRC, Kenwood, Radio Shack, Sony, and Yaesu are the most popular with a wide range of types. The Icom IRC-71, Kenwood R5000, and JRC NRD535 are on top of the list, closely followed by Sony ICF2010 and the Drake R8. The top of the decoders is formed by affordable gadgets as JVFax and its sister JVcomm32, Hamcomm, Radioraft, and PC-ALE. From the more expensive decoders, HOKA's Code3 is the most used one, followed by AEA PK-232, universal 's M7000 and M8000, Kantronics KAM, and Code30.
In antenna-land the longwire is by far the most popular antenna, followed by various types of di poles, verticals, and di scones. Most of them homebrew. Widely used are also the Wellbrook ALA1530 loop, the G5RV dipole, and RF-Systems' T2FD seems to be popular as well. Note that the 'antenna' and 'various' info is new in the database, so the available data is very limited. I have listed the equipment in four sections: 1) receivers 2) decoders 3) antenna 4) various The four sections are compilations of the original configurations as sent to us by ca. The exact configurations are listed as wel 1.0-0-0-0-0-0-0-0-0-0- if you didn't send your list to Mike or me in the past and want to be included in the WUN members database, please send me your details as follows. An alias instead of your name is no problem, of course.
