30M QRP CW Transmitter

A friend Bill Harbour was enquiring about various aspects of the design of CW QRP transmitters In particular his interest centred around the amateur radio band of 30 metres (10 000 - 10 150 Mhz) Various topics and design principles had been previously discussed and in the end I decided to present an experimental transmitter for CW (morse code) QRP (low power 5W) for operation on the 30M

Equipment for QRP Ham Radio

Some simple QRP transmitters may only act as transmitters and in this case a station receiver will also be needed as part of the QRP equipment line-up Again there are several options: Use receiver from existing station transceiver: One of the options open to many people will be the use of an existing station receiver included within the main station transceiver

WSPR: Raspberry PI 20 Meter 100mW QRP Transmitter

There are many WSPR protocol transmitters that can be purchased We went with the 20m WSPR-Pi kit from TARP The TARP kit was chosen for a few reasons: 1st) we understand the RasPI and had a spare 2nd) the 'kit' plugs right onto the RasPI GPIOs 3rd) it seemed really simple -----And really simple it was (kinda) We downloaded the software that runs the WSPR transmitter from GitHub

08 12 2013I like to take QRP to the extremes at times One of my favorite setups is a 1939 Meissner Signal Shifter that runs a good 4-5W out of a 6L6G and a pair of plug in coils for each band It is actually the military model used with the 150B transmitter and it has a continuous coverage coil set from the BCB to about 18mc The receiver is a 1934 National FB-XA also with plug in coils and I wound my own for
