Amateur Radio Station YB9BWN Beacon Transmitter


Welcome to my radio beacon page. The following is the beacon information:
Callsign: YB9BWN
Gridsquare: OI71oh
Beacon: Homebrew crystal-based with IRF510 PA at 2W into a dipole, controlled by a MC68HC908JK3 CPU.

Reception report can be sent via email to kwiadnyana (at) yahoo (dot) com.

The address of the beacon station is as follows:
Jl. Pemuda No. 10
Pojok Tukad Ayung
Denpasar, BALI 80235 - INDONESIA

The radio beacon begins operation on October 23, 2006. This page is continuously being expanded to include equipment photos and reception reports.

The beacon is a homebrew crystal-based transmitter. In its current form (version 4), it uses a crystal oscillator from the two-transistor Universal QRP Transmitter (found in Doug DeMaw's Solid State Design for the Radio Amateur), and it uses a variation of the VXO-Controlled Transmitter (from the ARRL's 1990 handbook). It has 4 2N2222A transistors, driving a 2N2219A with an IRF510 as a PA. Power output is 2W into a horizontal dipole, pointed Northwest + Southeast from my residence. The objective is to direct as much energy as possible to Europe and Australia. I am still hopeful that some SWL in Japan will be able to hear it.

Thanks for checking out my callsign and I hope to see you again on the air, CU es 73.
