Television and FM-broadcast Band DX into the Owens Valley, California
2008 - 2012 Television DX into the Owens Valley, California
Television DX photos: With the coming of late-spring and the summertime comes with it Sporadic-E skip. I am fascinated by the phenomenon of Sporadic-E skip as much as I am with natural VLF radio, so I undertake a project of capturing long-distance TV reception. Since the analogue shutdown in the USA in June 2009, I can now only receive E-skip TV from Canada and Mexico, but the Owens Valley is well-situated to be within 1-hop distance to several TV stations in Mexico and Canada, and if I am fortunate I can see even two-hop signals from southern Mexico and eastern Canada. Below is just a taste of this reception I have snapped photos of, or made screen captures from, either a VCR or quicktime movie captures. This page will grow with photos as I add them.
Time is running short for NTSC TV DXing - in August 2011 Canada will shutdown analogue TV stations, and in Mexico, they will do the same in 2022. If you click on the link underscoring "Television DX" above or here will bring you to a great Wikipedia article about TV DXing and its fascinating history. Also, search Wikipedia for "sporadic-e" skip. There are many clubs and groups devoted in-depth to this fascinating pursuit.

In the late summer of 2009, I also engaged in a project of capturing METEOR-SCATTER reception of TV Channel Two signals using a small, sensitive black and white TV set hooked to a log-periodic antenna (no pre-amp. employed). See below.
Most of the Black and White TV receptions were made via a simple 300-ohm folded-dipole cut for channel A2, prior to about 25 July 2009, when I employed the log-periodic antenna. (The Log-periodic antenna, pictured at bottom of this page, is the antenna of choice for the 2010 season). And so in essence, you don't need a fancy gain-antenna to capture NTSC-TV Es DX!
I use CB channel 19 (27.185 MHz) to advance-warn of Es openings: (much more dense signals on CB Ch. 19 than 10 meters, hence a better Es propagation-indicator channel, and also, I use CB channel 5 (27.015 MHz) for indications of Mexican Es openings. Then, when CB is hopping, I scan the 10-meter beacon band for signals to get the idea of the direction/region of the opening(s). Then I await the MUF to climb into 6-meters and low-band TV, if it does so.

Spring-Summer 2012 season:
A very early-season Es opening to Sinaloa, Mexico - XHQ Channel 3 (NTSC) from Culiacan, Sinaloa, Mexico (Grupo Pacifico) re-appeared for 1/2 hour this day! Reception via B&W Panasonic 515 and 1/4 wave wire clipped to its whip-antenna - SP McGreevy - N6NKS

Channel 2 XEPM Cd. Juarez, Chihuahua (55.250 MHz - zero-offset) came in again 29 June 2011 (UT) for 15 minutes, peaking in strength during a newscast - this image is during a weather segment at 0157 UT.

Friend Kirk W. whom lives north of Tucson, Arizona captured Channel 2 - KTVU Oakland/San Francisco using a color TV and log-periodic antenna pointed n.w. He snapped this photo the evening of the same day KTVU's (plus-offset) analogue signal left the air for good on 11 June 2009.
Meteor-scatter NTSC Television DX - Channel Two
The following images are of meteor-scatter reception of NTSC video signals on TV Channel 2. I use a very sensitive Panasonic Ranger-505 B&W TV set hooked to a 15 ft. (2.9m) long log-periodic antenna up 7 feet (2.1m) pointed eastward.
Two images of short-burst (< 1 sec.) Ms reception on channel two from random meteors about 1240-50 UT, 26 July 2009. The first I IDed as XEPM Cd. Juarez, and the other unID says "Viva Mexico."
A short-burst (< 1 sec.) Ms reception on channel 2 from a random meteor about 1235 UT, 27 July 2009. Most short-burst meteors exhibit weak, snowy pictures on my system. It is possible with better antenna feedline and a pre-amp that I could get clearer pictures.
Longer-duration Perseid bursts 12, 13 August 2009!
Amazing spectograms of meteors on Channel 2 video carriers (Kenwood TS480SAT USB mode).
