Finding a freq's point of origin
 

Pardon the newbie type question, but when I find a strong signal and would
like to know where the point of origin is, is there a method by which I can
search by the frequency to find out where it is originated from?

Triangulation. Usually only accurate on a groundwave.

Use a loop, make note of the compass heading.Drive 10+ KM to another spot
(the farther the better) and do another compass reading. Repeat for a
third time. Draw the three lines on a map and where they meet, there's the
vicinity of the transmitter.

- Check in "Passport to Worldband Radio" ( Book)
or Monitoring times ( Magazine & .com )

Well Passport To World Band Radio lists stations by frequency as well as
sevral links on the web

See URL:
http://ac6v.com/swl1.htm
AND
http://ac6v.com/swl.htm

Most stations Identify on the hour some more often -- match this with your
frequency listings should do it.

Unfortunately it's compiled using HFCC data... not always to be trusted
by any means...

Thanks for the feedback.

Mainly just scanning thru the AM band starting around 3.000 thru 10.000.
But I like to also tune into the LSB and USB freq's to catch the
conversations.

I currently tuned into 9.846 AM.

By the way, I just 're-oriented' my wire antenna (approx 80ft) into going
more vertical than what I did have. I suppose the higher the better!

Not much use if it's on HF and at a great distance.

Look the frequency up in the Klingenfuß guide or
the Spezial-Frequenzliste.

There are other books.

Gregg,

Beyond the Ground Wave and the First (and may be Second) SkyWave Hop.

The Signal gets to you: How it is going to get to you [.]
- - - Depending on the 'conditions' at the Time of Reception.

* That is 'why' an Omni-Directional Antenna is preferred for Receiving.

* And a Directional Antenna is preferred for Transmitting.
- - - To try to better 'saturate' the Target Area with Signal.
