That is from this wonderful page of RF ideas Homebrew RF Circuit Design Ideas These tend to be circuits only with no notes so a bit of a leap for a beginner. with the actual circuit diagram here A wireless doorbell may do what you want.

16/05/2000 · On the VFO question most of what you see these days are microwave oscillators based on dielectric resonators. They divide them down to RF frequencies with low noise divider chips. Mini Circuits sells the VCO/divider modules fairly cheap. Look for the stuff with phase noise numbers in the -150 dbc/Hz region. Once you have one running you can

Overview - Part 1. A RF spectrum analyzer is one of the most useful tools an experimenter can have. The spectrum analyzer project shown here will be a slight improvement on the "Spectrum Analyzer for the Radio Amateur" project from Wes Hayward (W7ZOI) and Terry White (K7TAU) which was covered in the August and September issues of QST magazine.There will also be a few ideas taken from the ...

Solid State Design for the Radio Amateur1 was a universal low power (QRP) transmitter. This was a simple two-stage, crystal-controlled, single-band circuit with an output of about 1.5 W. The no frills design used manual transmit-receive (TR) switching. It operated on a single frequency with no provision for frequency shift.

Design your circuit and board using your choice of circuit design apps. ... W2FMI has been my inspiration and source of most of the ideas. ... Although not designed for RF switching, these worked OK ... at least until water got into the box and they corroded away. ...

But these all tend to use RC bridges, which seem to suffer from large amplitude variations when adjusted. This makes re-setting them each time you move frequency very time consuming. The design shown below from G4WMX is a Null Steerer which is also similar, but uses tuned circuits to obtain a greater phase shift.

Wide-range high voltage lab power supplies could dissipate insane amounts of power if you try to extract a medium to high current at a very low output voltage, making your PSU dissipate the rest of the voltage from the filter cap to the output, multiplied by the load current as heat.
