Since a couple of years the 70MHz band is available for amateur usage in PA, I decided to build an all-mode (FM, USB, LSB and CW) transceiver for this band.

This purpose of this page is to give a brief description of a 70 MHz transverter that has been published in the Danish amateur radio magazine "OZ." This way hams outside Denmark may also benefit from the design.

There is almost no commercial equipment for the 4m band and certainly almost nothing from the traditional Japanese manufacturers. So, to get on the band it's necessary for me to design and build a simple transverter.

Oktober 2011 begon het er naar uit te zien dat we per1 januari 2012 in Nederland de beschikking gaan krijgen over een nieuwe amateurband rond de 70Mhz (4meter). Dit leek me een goede gelegenheid om weer eens een zelfbouw-project op te starten.
