3 Transistor 50MHz FM transmittor by JF1OZLIn Japanese CQ magazine, I informed about my 3 transistor CW transceiver (Jun1992) and 3 transistor SSB transceiver (Nov1992). I wanted to inform about FM transceiver, but it was not informed on that book.https://www.emilio.com.mx/jf10zl/3trfm.htm

50,06- 50,120 MHz TX by LY3LP http://sa555.blogspot.com/2011/05/5006-50120-mhz-tx.html
One Transistor TX (50MHz DSB) by JF1OZLI challenged to make very simple transmitter. It is constructed with only one transistor. It makes DSB signal. It can make QSO with normal SSB station.https://www.qrp-ja.net/jf1ozl/1trtx.html
The 6 Metre Beacon Project by GJ3RAXA few years ago I was asked, by Geoff GJ4ICD, to help design and make some beacons for the 6 metre band. These were to be sent to various parts of the world which were not covered by existing beacons.http://www.uksmg.org/content/6metrebeacon.htm
Two types of 3 transistor 50MHz DSB transmittor by JF1OZLI will show you two types of DSB transmitter. ** Type1 uses active modulator. Type2 uses passive modulator. Each type outputs the same 100mw power. And also each type uses three transistors.https://www.qrp-ja.net/jf1ozl/3trdsb.html
VHF signal generator by JF1OZLI made a simple VHF signal generator in order to measure the characteristic of low pass filter. The filter is made to use on 50MHz SSB transceiver.https://www.qrp-ja.net/jf1ozl/vhfsg.html
