[ARC5] Basic Question

[Chris Bowne]

I have a BC-451 control box installed as part of my crossbreed ARC-5/SCR-274/ATA command set system that I use just about every week on the Sunday night Old MilRad CW net,  I have on occasion resorted to using the 451 Morse key when my regular key, usually my WS-19 knee key or my J. H. Bunnell has had their lever arm come flying loose mid transmission.  The 451 key has a very strong return spring and you don't want to send very long with it.  It can be spun down to lock it on. As was mentioned that feature was likely provided for putting out a DF fix transmission, especially in an emergency bail out situation.  I find the lock down handy when tuning up the system.  73 de Chris AJ1G

I have a "letter" from, it appears, Wright Field instructing maintenance personnel to remove the Morse key from control boxes as flight crew were found to have jammed various books and such on top of the control box and keying the transmitter inadvertantly.  It goes on to say that when cw or mcw was required for D/F steers, simply key the mic.  It specifically mentions C-47 (R-4D) C-53, and C-54 (R-3D) aircraft that came from the Navy.  Does this jibe with other info??

Now, pilots in that era received  Morse Code training, and although that probably was primarily intended to enable them to translate the code from NDB's was there any radio equipment designed to enable pilots, rather than radio operators, to send and receive Morse Code signals?
