He also appeared regularly on Sky News' weekly Technofile programme, reviewing gadgets alongside presenter Martin Stanford and was a regular contributor to Media Network, a communications magazine on the English service of Radio Netherlands.
Tomalski started his broadcasting career on the south west London pirate scene of the 1970s, when he was the host of Roger Tate's Mailbox Show on European Music Radio, and later became a licensed amateur radio operator with the call sign G6CQF.
His maisonette in Mitcham, Surrey was equipped with a broadcast-quality mixing desk and two Nakamichi cassette decks, alongside the high-quality turntables.
Another technology which Tomalski pioneered was that of computer data transmission via Band II FM radio - raw data transmitted onto the audio signal with no subcarrier: WVR featured the "Roger Tate Computer Program Programme" with Tomalski introducing (after the music had ended for the night) half an hour of 8-bit data sounds played from a Nakamichi cassette deck, representing programs for the BBC Micro and the Tandy TRS-80 microcomputers, among others.
He also broadcast for Radio Mercury and Radio Invicta (which also sparked the career of Steve Walsh), and was the resident 'Inspector Gadget' on the LBC Weekend Wireless Show, talking about the week's technology news, reviewing gadgets and answering listener queries.
