Back in the 1960s at university I worked ZB2VHF on 4m AM with 4W and a ground plane. At this time there were very few countries on the band. In 1971, I went /P in a 4m contest.
Several years ago I made a QRP transverter for 4m that appeared in SPRAT (shown in photo). I have no antennas for the band, but a local has made a personal beacon, that I shall try to copy. It produces 10mW. He has a vertical colinear for the band.
