[martin griffith]

Any ideas who make a RF, 860MHzish chip set for stereo audio, like
this
http://www.sennheiser.co.uk/uk/icm.nsf/root/09917#.
Been googling, Rohm LPRS etc, too no avail

or are they a total custom job?
thanks

Sennheiser is a big microphone company, who invented the wireless mikes.
They are fabricating in Burgdorf, Germany (not in China!) There are no
"chip-sets", it's not a cellphone. You can find modules though.

That sounds to me as though some salesman has been re-writing history.

Wireless mics have been around for a very long time and a company I
worked for in the 1960s had been making receivers for them, to special
order for the BBC, many years before they came into more general use.

According to the history page on sennheiser.com, the wireless "Mikroport"-system
was introduced in 1958. Seems quite early to me. Maybe they weren't the actual
inventors, but at least they brought it into public usage, as mikroport is still
a synonym for wireless mikes.
