RX Receivers

Equipment

TX Transmitters

Equipment

Nowadays, transmitter usually is part of transceiver, that is why is chapter mostly dedicated to self-contained transmitter projects, such as radio beacons (telegraph, WSPR and APRS).

XCVR Transceivers

Equipment

A transceiver stands for TRANSmitter/reCEIVER, a combination of receiver and transmitter. Usually, a main element on radio amateur desk ("shack") and a door (or window) on the air.

ANT Antennas

Equipment

Antennas are all of sorts. They can be big, very big and strange. Due to the limitations of my locations (QTH), mostly, I build portable antennas.

PA Power Amplifiers

Equipment

Power amplifiers are intended.. hmm.. to amplify power of outgoing signal from transmitter to antenna. I would categorize power amplifiears, very broadly into three categories: low power QRP (to 20 W), normal power (to 100-200 W) and high power QRO (all above)...

PSU Power Supply Units and PDU Power Distribution Units

Equipment

To be able to emit radio signals, we need energy. That energy, usually, comes from the socket, but not always. This chapter is all about it.

Capital Region
