630m Band 472 to 479kHz Transverter
The complete high performance 472 to 479kHz 630m Band, 5 Watts of linear output

630 meter antenna Limited edition!
Due to the increase of sunpanels and PLC devices, the HF radio spectrum is more and more polluted. Add to it that in NL there is certain group of sunpanel "pioneers" who consider themselves capable of installing these devices by themselves

4 Band CW QRP Transceiver Homebrew 4-bander cw qrp transceiver for the homemaker, the design is based on a classic dc receiver and a class c transmitter

The Folded Dipole

The Folded Dipole The Folded Dipole is not used much amongst Radio amateurs, probably due to the fact that this antenna uses twice as much wire as a single-wire dipole

50 MHz preamp Gain 26dB with the BFG135

50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
