Veteran DJ Dave Lee Travis was "touchy-feely" in a "nice sense", a former BBC colleague has told a court.
Philip Hughes, who worked as a technical operator for the BBC from 1973 to 1980, said he never saw any "inappropriate conduct" by Travis when they worked together on Radio 1.
He told jurors at London's Southwark Crown Court he would have been "slightly concerned" had he seen somebody having a "physical tussle" with the DJ in a studio.

Travis, 68, is on trial accused of indecently assaulting 10 women and sexually assaulting another while working as a BBC DJ, as a broadcaster with Classic Gold radio, while appearing on Top Of The Pops and when starring in panto.
He denies all the charges.
Asked by defence barrister Stephen Vullo how he found Travis as a character to work with, Mr Hughes replied: "I personally liked Dave. He was a fun and larger-than-life character, nice bloke, great sense of humour.
"He was part of the furniture at Radio 1."
Mr Hughes said if technical operators had been made aware of a sexual assault, it would "probably have been talked about".
"He was the sort of person who would give a bear hug in the corridor," he went on.
"Blokes as well as anyone working on the programme. He was touch-feely in that sense but in a nice sense of being touchy-feely. Some people aren't."
Mr Hughes said he found people from "the North", such as Travis, were "more open to being warm with people".
"Tony Blackburn was not quite like that but he's from Bournemouth," he added.
Mr Hughes said he often "instigated" pranks at the station involving Travis and fellow Radio 1 DJ Noel Edmonds, including sugar lump fights and placing a cup of water over the studio door.
Asked by Mr Vullo whether any pranks would have involved "sexual touching between men and women", Mr Hughes replied: "No."
Asked whether he could recall any "inappropriate conduct" by Travis, Mr Hughes answered: "No, I don't."
Travis, from Buckinghamshire, is charged with 13 counts of indecent assault dating back to between 1976 and 2003, and one count of sexual assault.
He is appearing in court under his birth name David Griffin.
The defendant, wearing a dark green jacket, white shirt and patterned tie, listened to the proceedings in the dock with the aid of earphones.Suggest a correction
