10m Projects - Transmitters

Click to enlarge10m WISPY WSPR beacon by G3XBM
WISPY is a simple DSB beacon transmitter for 10m WSPR. The idea was to use a low cost 14.060 crystal, available from many sources, in an oscillator-doubler circuit feeding a diode single balanced mixer and small low cost PA.

In this project, you will make a simple 3-stage low-power broadcast-type circuit, using a crystal oscillator integrated circuit and an a collector modulated AM oscillator with amplifier.

Nice emitter manipulation of the T1. T1-T3 any 150mc transistor. T4 is 1w, or two 2n2222 in parallel. T50-6 rings, perpendicular. If more power needed one can connect NB6M QRP "gallon".

Click to enlargeAMA-TIRI by PY2OHH
After the success of the CANARINHO, CURRIRA and the CURUMIM we decide to build a QRPp transmitter, now for 10m . This is the AMA-TIRI.

The 27MHz radio control receiver project and the proportional R/C encoder/decoder project were created many years ago. The transmitter portion has never been published.

Click to enlargeJones Transmitter by DK3BI
The first time I came across this circuit was in 1964 when I read the book "Simple Radio Control" by H.G. Hundleby. It was called the "Aeromodeller" Transmitter and was a free running oscillator without a crystal.
