Cole and Cheesman use the phrase 'radio telephony' to distinguish 'wireless telegraphy' (by morse) from 'radio telephony' (by direct speech). The other typos aside, the rest of the posting stands. Nick PS I believe that the correct way to end a radio telephony transmission is 'Out'. -----Original Message----- From: Peter Wright [mailto:wright.brother@btopenworld.com] Sent: 29 January 2003 08:42 To: Multiple recipients of list Subject: [CCI] Re: W/T Nick, I'm sorry to labour the point, but the transmission of speech by wireless is WIRELESS TELEPHONY not wireless telegraphy, which is the transmission of morse. See my opening paragraph in article 'Its Good to Talk' in Vol 30 No 4 1998. This is also confirmed in chapter two of the Biggin Hill book, of which I only have a paperback copy. Over and out!
