Double loop idea: The question

Zacharias Liangas
 

As in the previous thread the topic the question was changed to hunting 74 megazine I m again asking any members to advise me
IF  anyone has experimented on using double loops with phasing to produce a cardioid antenna pattern or slightly more narrower - by just turning the shadow loop!
This is an idea of the past
any ideas ?

The frequencies below about 800 just don't seem to do well here and have some noise but.. i got a pretty good signal at 1400UTC, tail end of national program, with ABC fanfare and news intro. Also had them about 15 mintues prior, will have to review recording and see how good all the audio is.

Just thinking the IP problems if any !
MY idea is still clear : Using phased double loop to make a cadioid pattern for better killing of unwanted stations or noises ! 

goh! For such a big secret people will want to share the pdf? ;-) ?

Hi

The graveyard channels in the USA are 1230, 1240, 1340, 1400, 1450 and 1490 khz

On these frequencies these stations can run a maximum power of 1000 watts

In earlier years ie back in the 60s - I think their max power was 250 watts

A double loop idea!

Hello

This is a article from the old 73 magazine referred to  the discriminator antenna designed for 1.6-4 MHz to provide cardioid pattern lobes for reception only using phasing technique  with a loop and a telescopic antenna . It was given to a friend to a  friend to get an idea on how he can redesign that for MW usage

https://app.box.com/s/nc0qnfc37m4tr3ugwbicozgofcyd65ai

Notice that the file in view only mode and will be deleted soon !

 

Based on this idea . I  a asking if someone used two loop antennas together with phasing to provide more than  heart shaped pattern for medium waves !

This was my idea since the time i kept handy this article


Did anyone made such project?

Thanks Gary,
Yes, i've read your HK report, I noticed you got Vesti FM. Your mystery 648 might be Botswana but not enough to go on.
The PL-360 loopstick is a tad smaller than 7.5'' :)
My reception was in a ground floor room.

Peter

Re: Basic newbie questions

Hello Jock, at the top of the MT page, click on 'community' then 'list of stations' and find some stations nearest to you.

Keep an eye on these stations reception range maps and if you see unusually long range ship reception then that can be an indicator of possible ducting. Usually happens in hot weather and/or high pressure (subsidence).

My map:

Similar idea, but for aircraft https://flightaware.com/

You can contribute by uploading ship (if near a coast/waterway) and aircraft positions. Great projects!

Grant.

Thanks, Les, but FSL-DXing results depend entirely on the skill, knowledge and determination of the operator-- not to mention the willingness to test all of these in subfreezing cold every morning in a remote environment. I would be the first to give Paul 99% of the credit for his awesome transoceanic and Trans-Arctic DXing achievements.

Head to Head Testing - Walk Radio DAB-P9 v AR-1733 - FM Band

Paul Blundell
 

Over the weekend I undertook some head to head testing between my Walk Radio DAB-P9 and Digitech AR-1733. This was undertaken in my front yard, using the standard whip aerials of each radio. The results are shown below. 

The  Digitech AR-1733 logged everything the Walk Radio DAB-P9 did plus five extra stations. In this test the Digitech AR-1733 clearly had the edge.
