[CQ-Contest] Wireless headphones/mike

[Gary A. Nieborsky PE]

Our system dispatchers played around with wireless head/mic sets for awhile
and finally settle on using a Motorola system using 450Mhz HT's and a
receiver slaved to the console.  They dumped the system when it became a
nuisance.  The problem was that the rx/tx switch over time added to the
console keying time caused a significant increase in "doubling" and the
resultant confusion.  They've now gone back to the ear-piece/tube mic.  A
full duplex system would be much better but my telecomm engineer says he
hasn't found one on the commercial market........
