In 2005, I had organized a group purchase for European transistors. In this program, BC547, BC639, BD135, BD139 and TBA820M had been listed and about 20 Japanese hams had joined.

A borderline insane 30m QRSS beacon project. The beacon contains an 8K EEPROM (28C64 chip) of which only 1K is used. It is programmed by hand from front panel switches.

Click to enlarge30m QRSS Junkbox Beacon by GØUPL
Here's a 30m QRSS beacon whose main objective is low cost and simplicity. I built this project entirely from junk box parts: the only component purchased specifically for this project was the 10,140kHz crystal ...

Click to enlargeA 10MHz QRP transmitter by F6GLZ
This home made transmitter will be the companion of my low band receiver soon described here. In fact, it is a synthesis of several modules already tested separatly.

A Two-transitor Transmitter for 30 Meters by KB4PY
When I decided to become active on the 30-m band, I wanted to build a simple transmiter. I have a Yeasu FT-101E that receives WWV on 10MHz. Others may have general-coverage receivers, and need only a transmitter.

Click to enlargeTiny 30m WSPR beacon” by PA2RF
I was looking for a small WSPR beacon for portable use. When reading the blog of Roger, G3XBM, I ran into the WISPY TX beacon. I converted his 20m beacon to a 30m version.
