[ARC5] What Were They Monitoring?

[Bart Lee]

Hi Jeep,

I wrote a couple of papers on Swan Island, history and covert events.  What
can you tell me about "The HH on Swan had dual transmitters…"  Who? What?
Where? When?  Why?

See:

Swan Island, its Radio History Including the CIA and the Revenge of United
Fruit <http://californiahistoricalradio.com/CHRSPix/BartLeeSwan.pdf>

Swan Island Slides, United Fruit Company Wireless, Amateur Radio Stations
and the CIA
<http://californiahistoricalradio.com/CHRSPix/BartSwanIslandSlides.pdf>

and more at www.californiahistoricalradio.com/radio-history/bartlee/

Thanks, 73 de Bart, K6VK

P.S. I'm C.A P. COP 1963 signed by Gen Curtis Lemay no less!  ##
