[BC] "Portable" freq. agile AM TX

[WFIFeng@aol.com]

Does a frequency-agile, rack-mountable transmitter exist? I know that 
Armstrong has one that may almost fit this description, but I'm looking to find out 
if there is anything else that is relatively easy to set up "in a pinch".

We want to buy such a box that could be hauled in the back of a car on a 
moment's notice and set-up on-site. Anything in the 500w to 1Kw range would be 
ideal.

We have 5 AM's in our group. The freq's are as follows:

760   kHz
1230    "
1320    "
1500    "
1590    "

Suggestions?

Willie...
