30 meter receiver low power qrss beacons and psk31

30 meter receiver low power qrss beacons and psk31 That is possible by using a low CW speed. QRS mean reduce your CW speed. With that extra S of QRSS they want to indicate that it is really a very low CW speed

The Folded Dipole

The Folded Dipole The Folded Dipole is not used much amongst Radio amateurs, probably due to the fact that this antenna uses twice as much wire as a single-wire dipole
