40 Meter Rotatable Dipole
It is an excellent all-around 40 meter antenna for those who don't have room for or can't afford a yagi
44/28 MHz Transverter
Sono stati sviluppati i relativi circuiti stampati utilizzando dove è possibile utilizzare componentistica di tipo SMD
6AQ5 CW Transmitter
How's this for no-frills hamming? This cute little 40 meter CW transmitter is nothing more than a 6AQ5 oscillator coupled to the antenna
6m Yagi-Uda Antenna Computer Simulation Design
I first saw such kinds of articles on Japanese CQ magazine or Japanese Ham journal No.65 in late 80's. I recognized that there was a trial of let's do the optimization of the antenna by using a computer
A 2 MHz Transverter Project
supply voltage 12 vdc +/-X @X ma, IF of 28 MHz for Tx and Rx
170

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
