New HiFer "SPT" Beacon on 13558KHz
« on: November 01, 2015, 0142 UTC »
Hi there -

I just put a new HiFer beacon on the air. It sends "SPT" on 13558KHz at about 6wpm continuously. with a power of 4.6mW into the antenna, an L-shaped half-wave dipole at 25 feet.
It has been heard with a 239/339 in Portland, OR, a little over 500 miles away, and I'd love to know if anyone else can hear it.

Just tuned to 13558 and I don't hear it in Chicagoland. On 13560 I hear constant rhythmic chirps and beeps from the Elk Grove industrial/commercial park about 5 to 7 miles south of me. That park is just west of O'hare field. Kenwood R2000 and 7mhz backyard dipole.

I have been using online receivers because of strong data hash interference in my neighborhood that I believe is caused by Uverse squeezing up to 100mb/sec through ordinary pairs of wires. I don't have Uverse but neighbors do. williamhassig@yahoo.com

13558 KHz is a sewer of noise in central Florida with the same chirps as William described. The hash and chirps are 24 hr/day here. SPT would be in the clear here if you could move SPT up above 13660 or below 13557 KHz.

Thanks for trying William, and thanks for the input Dag. Unfortunately, 13558 is the lowest I can pull the crystal, though it will pull as high as the top of the ISM/HiFer band. I don't want to make any changes yet, until I get more feedback, but am very willing to move the frequency above 13560 if it seems that would work better.

Have been looking for SPT here w/o luck.  The freq is generally quite clear.

MTI (Georgia?) variable right now fair to good on 13557.5
WV ( West Virginia?) weak on 13555.8

I can't hear any beacons. This HiFer stuff is all pretty new to my SWL routine.  I'll keep listening!

Chances are slim I could hear SPT in EM98, but I'll keep an ear out for it!

SPT was heard briefly today by a hiker in Pike National Forest - a direct distance of about 900 miles. I think that's pretty good for 4.6mW into a dipole. Makes you wonder what a 100mW beacon could do. I'm too chicken to break the rules though, so I'll have to imagine!

Thank you for listening, jFarley and Frank. I believe that FRC (which is also in Northern California) has been heard in all 50 states, but I imagine it has a much better location for it's antenna installation than SPT, being in a broadcast transmitter building. I'd be surprised (yet overjoyed) if either of you gentlemen were to hear SPT.

Nice to see you on here Frank :-) Mingus is the name of our neighborhood cat, hence my screen name.
