10 Mhz QRSS Beacon


Posted on Feb 7, 2014

My beacon is using now a simple CW keying QRSS3 10140. 020 khz, power is 20 milliwatt. I`m using a PIC program PicBeacon di Ik2pcb. Click here for the reception report The idea of making this beacon start from two project, one is the Hans G0GPL QRSS Junkbox Beacon and the other is the simple `2 transistor` project from Colin G6AVK.

this two circuit and also looking idea from Alessandro I0SKK Beacon i start the builing with ugly construction (or ground-plane construction) my beacon. Using a simple 10140 khz xtal (Tnx Peter DL6NL !)i build the Colpitts oscillator and the "power" stage with a 2n2222a transistor. In the first test the "low pass" filter is not used as you can see in the photo, as a "band filter" i`m using Kenwood Antenna Tuner. A simple circuit with NE555 is used as a patten generator, and in the ARGO screen look like a lot of "T" in morse Code. The frequency is 10140. 020 Khz.
