Copied from an e-mail I just received:
With special thanks to Chief Engineer Daniel Appellof, and Broadcaster/DX’er Paul Walker, we have arranged for a DX Test tonight for KKOH 780 Khz in Reno, Nevada. At approximately midnight Pacific time, KKOH will switch to 50 KW Non-directional. They plan to run 15-20 minutes of DX Test material that we have provided.
This material includes sweep tones, Morse Code IDs at 700 hz (10 words per minute), telephone off-hook sounds, and vintage voice sounders for the station. The sweep tones and telephone sounders are especially good at cutting through noise, and should give many DX’ers a chance to log the station.
After the test period, KKOH 780 will power down the transmitter for additional maintenance. This will provide a “silent period” for West Coast DX’ers to log new stations on 780 Khz.
When the maintenance concludes, the station will power back up. They may or may not repeat the DX Test material at that time. The maintenance is expected to take about six hours, possibly less.
This is a rare chance to log Nevada, and for those in the Western US to log new stations on 780 KHz as well.
Please spread the word via e-mail lists, chat rooms, etc. DX Tests are rare these days. I hope that everyone will join me in expressing our gratitude to Daniel and Paul.
