When I worked for the city of Dallas we operated an old Western Electric 1  
kW. on 1714 kHz. with the call letters KKB-364.  It was left over from the  old 
AM days of cars being on 35 mHz. AM and talk out being on 1714kHz.AM. They  
used it mainly for paging warrant servers and they used their regular car AM  
radios.
 
Glen you mentioned 1606 kHz.  that was an RPU frequency, as I recall  there 
were three of them, AM frequencies above the broadcast band.  WKY in  Oklahoma 
City used to have a Flexible bus with remote studios before the FM days  and 
used a 250 Watt broadcast transmitter on 1606 kHz. to relay audio from the  bus 
to their studios.
 
Before Martis, many RPU's were AM on 26 mHz.  WRR in Dallas had a  Globe King 
500 Watt base station on 26 mHz. many years ago. WRR later on  converted to 
26 mHz. FM with modified Motorolas.  WRR was the first user of  Marti Equipment 
in Dallas.
 
KNUZ AM in Houston, Ed Martin had a 100 Watt transmitter on 1606 kHz.  
feeding a slant wire on his 1230 AM tower for employee paging and calling.   They 
adjusted the trimmer on the car radios to pickup 1606 kHz.  They also  had a 
station in Beaumont and the would feed commercials and news feeds to them  over 
that AM RPU channel.
 
Darryl Parker now @ TFT told me that they were once  looking into  using 
those AM frequencies above the broadcast band with the old Heathkit SSB  
transcievers so they could communicate wth their Texas State Network key  stations from 
Fort Worth to Austin to Houston. A 100 watts SSB would probably do  a great 
job.
 
Old memories.
