KWHR is going away

Post by donmussell » Sun Oct 12, 2008 2:36 am

I ran into Larry Vehorn this evening at the Honolulu Airport. Larry is Director of Engineering at Lesea Broadcasting. Larry was on his way to Kona, and he will oversee the dismantling of the shortwave facility at South Point on the Big Island. One of the SW transmitters will be crated and shipped to Saipan, and the other to South Carolina for reuse at those facilities.
Larry says that if no buyers show up in the next week or so, the towers are coming down. Here is a picture I took last winter of the array:

The reason for turning off this facility? Partly due to poor signals in the target area in Asia, and the cost of electricity on the Big Island (about 35 cents a KWH). Saipan is only 1800 miles from the Asian target area, compared to over 4000 miles from Hawaii. Here are links to the KWHR site (Photos and tech info):

SC is not that far away. Any chance he might be able to get a tour set of of the SC facility?

Heh, heh! 500 kW into a dipole curtain array will achieve that ERP, but (within 3 dB) only over a small sector of sky.

However, that ERP is puny compared to the HAARP installation in Alaska - up to 3,981 MW ERP (96 dBW)!

Still, i can only imagine how powerful and strong that signal is.. with that much power these SW arrays must be in quite rural places....
