I missed this but
G3TDZ, John Hey is a silent key now. He wrote a very nice article in Wireless World on a 2m AM handheld some years back and was inventor of the Heyphone which was widely used by cavers. He did a version for the 73kHz band too. He wrote to me several times. I think he died earlier this year.
I read this in the Radcom SK column a month or so ago, John Hey G3TDZ will be remembered for the WhiteroseHF phasing receiver and transceiver projects, cave radio and LF designs and his work he did for the G-QRP club.

I had been in contact with John late last year he was always happy to help.
Sadly missed but his designs will go on.
