DK8KW Longwave Information Slow CW
overcome this limit, many stations use so-called Slow-CW
30 Meter receiver for low power QRSS, PA2OHH
That is possible by using a very slow CW speed. QRS
10Mhz WSPR and QRSS Transmitter Project, G0FTD
The latter simply means sending very slow morse code
10 Mhz QRSS Beacon in a box, IW0HK
The power of the beacon is 20 mWatt
30m QRSS Beacon Transmitter, IK0VVe
invitation to slow down CW morse code
30m QRSS Junkbox Beacon
This simple 30m QRSS beacon is built entirely out of junkbox parts
30m QRSS Receiver,9H1LO
This receiver designed for 10.140MHz. It is intended to be used for Slow Morse
A 30 Mtr Direct Conversion Receiver, M0AYF
It is a simple Direct Conversion design
Audio Spectrum Analyzer, DL4YHF
This program started as a simple FFT program running under DOS

Il software che ho usato Argo, realizzato dai due radioamatori italiani
ICBeacon LF CW/QRSS beacon
This simple beacon is born after discussing with Giulio, ik2ded, on some ideas for LF
The amplifier uses a BC547 as a driver and two pairs of BC547's
