You need an antenna that receives signals from all directions - called omnidirectional.Materials make no difference: any type of wire is good, as long as it keeps its shape.

The ATS-909 Memory Circuit The following is courtesy of Jim Bowlin: As has been suggested in this group in the past, the "Data In" connections on the bottom of the DX-398/AT-909 are indeed connected to a nonvolatile memory chip that holds all the preset information.
The diagram below shows the relevant circuit details. The X24164 is a 2048 x 8 serial EEPROM from Xicor. The uPD78063 is a microcontoller made by NEC. It appears that if the NEC chip puts pins 94 and 95 into a high impedance state when they are not being used then it would be possible to read and write the preset information via the "Data In" connections on the bottom of the unit.

The following page is based on Radio Netherlands' pamphlet «writing useful reception reports».
You can obtain a free copy of this publication writing to: English Section, Radio Netherlands, P.O. Box 222, 1200 JG Hilversum, Holland. Introduction In the mid-80's we produced a simple pamphlet designed to explain how to write a useful reception report for most international broadcasters. International broadcasting across borders is very specialised form of programme making. Reporting and QSLs. "QSL" is the radiotelegraph code meaning "I confirm.
" In shortwave listening, a "QSL" is a card or letter from a radio station confirming that the recipient indeed heard the station. In the early days of radio, stations were eager to know how well they were being heard. To encourage listeners to write in and report their reception, stations offered to send listeners souvenir cards and letters Soon SWLs began to collect these QSLs from stations as avidly as many people collect sports cards today.
Most international broadcast stations today use regular monitors to assess how well they are being heard and no longer rely upon listener letters. However, most broadcasters still respond to listener reception reports with QSL cards or letters. A rare QSL! To receive a QSL from a station, you need to send a "reception report" to the station giving information about what you heard, the reception conditions, and what you liked (or didn’t like) about their programming.
