Band-Pass Filters for HF Transceivers
from intrastation interference these handy and inexpensive filters can help

Clean Up Your Signals with Band-Pass Filters
design of band-pass filters that provide a level of selectivity and reliability heretofore unavailable

Clean Up Your Signals with Band-Pass Filters
a series of band-pass filters BPFs between 150 W transceivers and 1500 W amplifiers

Crystal band pass filters for QRSS applications
a good RX band pass filter will be an important feature of any future design

Coaxial Stub Filters
You should not need to use a narrowband filter after a transmitter

Simple Rtty codec system based on arduino e android A unit for receiving Rtty transmissions was created, the differences are essentially limited to the Arduino software used

All band dipole Mk2 The All Band HF Doublet is often referred to as a random length dipole as it is generally as long as the available space within reason, but here are a couple of limitations to the ultimate dipole length

160M 1/4 Wave Vertical 160m vertical antenna project. It is 100' of Rohn 25G and a 20' aluminum stinger. The base is made out of four 6' power line insulators sandwiched between two Rohn base plates. 7/8' stainless bolts hold the assembly together. 32 radials 50' long and 30 radials 100'

Visual CW Tuning Indicator

Visual CW Tuning Indicator Many transceivers set the CW transmit off-set equal to the set's sidetone frequency. But it was left to the operator how to match incoming signals to the sidetone for one-frequency QSOs an awkward and time-consuming procedure
