Dave was very active on the VHF bands and was well known to those operating on the 50 MHz (6m) and 70 MHz (4m) bands.
He was also one of the pivotal figures involved in helping the IARU secure a full 2-MHz allocation from 50 to 52 MHz.
Dave was first licensed as an amateur radio operator in 1963 as G3SDL. He has also held various call-signs in a number of countries, including F0CWN, OZ3SDL, S21BI & A92IO.
In 1997, Dave moved to Ireland and was issued the call EI3IO.
He was also the co-founder of the QuartSlab crystal company and many radio amateurs will remember their adverts in radio magazines from the 80's and 90's.
