1/4 Slopers 40/15M Band The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 MHz and the top fed sloper was the most convenient installation having the least impact

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

DHD Double Half Delta This is a dhd double half delta in theory it should return a low signal but with a good s - n ratio roughly like a beverage

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
