Preamplificatore per la banda dei 136 kHz
Si tratta dell'amplificazione dei segnali sulla banda radioamatoriale dei 136 KHz

Preamplificatore d'antenna 144 Mhz
Il preamplificatore ha un guadagno elevato con una cifra di rumore molto bassa, si presta benissimo alla premplificazione dei deboli segnali proveniente dai satelliti

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

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'

DHD Double Half Delta

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
