Re: Question about AM Station Power - Why so low?

The FCC hasn't the resources to care about no-harm-no-foul infractions. The only way they would get involved in a situation like this would be if they received a legitimate complaint of interference from another station.

I've also been picking up WELD off and on since last Dec., with my last reception being on Feb. 25.  The distance to my location in southern Ontario is 295 miles.  Usually all I'm hearing is CKGM (50kW) in Montreal.  Sometimes I can hear WELD faintly underneath, but at times WELD would ride up right over them.  This would occur after midnight when they should have reduced power, unless something has gone wrong with their power reduction switching.  However I would think that the FCC would be on them if they've not been reducing power for any length of time.  This is one of those situations where every night I expect to only hear CKGM but surprise, surprise, this little low power station pops up due to the vagaries of propagation.  That's the fun of it.

Good answer but one additional note is that they may not have reduced their power appropriately when you heard them. For a crowded frequency that is a long distance for 14 watts, although nothing is impossible. Many times these power reductions are automated and especially with the recent change to Daylight Savings Time they may have been at their higher daytime power/pattern when you caught them. Just guessing.

Are they limited by the FCC or just don't want their signal to go too far? I thought the general intention was to reach as many listeners as you can?
Yes/yes and yes, but within the terms of their license.

The are protecting other stations of higher classes on the same or
adjacent channels from interference at night. There are many stations
that operate at 50 kW non-directional, 24/7, but not as many as there
used to be and whatever value there was in trying to entice
advertisers in your night contour seems to be gone these days.
Regardless, if you *ask* a higher class station if they want their
night contour protected, they are unlikely to say "meh". So the rules
assume that they require protection, so you end up with stations
running 14 W at night and that probably covers their City of License
adequately.

Question about AM Station Power - Why so low?

Johnny
 

Hi all,

Last night I had a nice catch of WELD, AM 690, from Fisher, WV to my home in Southern MI (USA).

The distance was 330 miles, but what made it cool (to me) was that the station was only putting out 14 watts of nighttime power.

Why so low?  And why 14?  Why not 15?

Are they limited by the FCC or just don't want their signal to go too far?  I thought the general intention was to reach as many listeners as you can?

Thanks!

MW Frequency Challenge - Week 16 Results and Week 17 Announcement - 540 kHz

DX Central - Loyd Van Horn (W4LVH)
 

Greetings!

First, a bit of housekeeping:
  • We have only SEVEN episodes left now of DX Central Live! as we will be running our final episode of Season 2 on Sunday, May 1st. 
  • With the arrival of Daylight Saving Time, the start time for DXC Live! is still 1945 CDT Sunday night, but this is now 0045 UTC (Monday morning UTC).
  • I am already making plans to map out Season 3, but wanted to take some time to allow folks to concentrate on FM DX season (which I am still trying to figure out how to livestream FM DX sessions without getting nailed by copyright strikes like I did last year by YouTube).  
On to the challenge....

A big week last week with 273 loggings coming in!  Congratulations to Mike Jeziorski in Mexico for taking our top spot this week with 28 loggings!  We also have a new reception distance record and more!  Full recap of week 16 can be found at the link for the blog post, below.  

You will also find the link for our Google Form for Week 17 as we explore 540 khz.  An interesting frequency and one that I admittedly have not spent nearly enough time with over the past six months!

Re: ULDXIndex and MWDXerDB V22.03

Jorge Garzón <iberiaDX@...>
 

When I introduced back in april 2021 the ULDX Index I wanted to get a math value (an Index) easy to be recognized internationally, obtained in a quantitative way, as always numbers show. Under these premises, experienced DXers face the challenge: distance and power of a given station. To achieve a difficult DX we experiment, design antennae or choose a vantage spot to hear weak signals. How difficult is DXing a station with an UL receiver? That's the value shown by the Index: the higher the score, the most difficult challenge to face! 

The way to calculate is easy: D (distance, km) / W (power, watts). 

Thee is also a world recognized code to show a signal quality: the SIO and SINPO codes. Scored from 1 to 5 gives an idea of the listening conditions:

S: Signal strenght, I: Interference (QRM), N: Noise (QRN), P: Fading, and O: Overall quality. 

Signal strenght can be accurate with a signal meter, but a few ULR have implemented them, and those with give erratic readings. 

Interference can vary in very short distances or depends on electronic devices around. 

Noise increases or decreased according to regional conditios or meteo conditions. 

Fading is related to surroundings, combination of waves and propagation itself. 

Overall signal is a combination of the former ones and includes the subjective sensation of listening comfortability. 

Quality of the signal values have then more to see with QTH conditions, meteo, or qualitative aspects. Use them as ULDX index modifiers would distort a quantitative math index. That's why they are not included as a part of the index score itself and that's why SIO/SINPO was implemented by DXers many years ago. 

Of course DXers can achieve the challenge as they prefer, but in my opinion the way to calculate the index should be kept in a quantitative method as this is a global way to compare by numbers the challenge to get that wanted DX with an ULR.

Jorge




Re: [irca] has anybody received a QSL from KJJR-880 or KQKD-1380?

Les Rayburn
 

As we’ve messaged on the email lists, our priority is to arrange for additional DX Tests before the end of the season. Between us, we have two additional tests that are a strong possibility, but the effort is requiring some “hand holding” with the stations because they are extremely busy with March Madness. 

DX’ers must quickly accept the new “norm” of getting QSL replies. Gone are the days when they can expect to receive QSLs quickly or perhaps at all. Constant inquires into when they will receive them, or speculation about who has or has not received them isn’t helpful either. In the case of the KJJR test, I’ve received duplicate reception reports from some DX’ers 5-7 times. 

All the work of the CPC is done by volunteers who have full-time jobs, families, and other responsibilities. Verifying receptions from a single test, generating QSLs, and a report for the station can take days of effort. That time simply hasn’t been available yet this season. What I’d like for DX’ers to understand is that patience is going to be a key part of this hobby going forward. It’s 2022, not 1962. The world has changed.

Re: ANNOUNCEMENT: Update to DX Central Live! start time for DST and end of Season 2 is coming!

James Rohrer
 

Loyd,

FYI, your classification of DXers showed me the Casual Logger category, which fits me to a T. This was an affirming insight. I like adding new stations to my list but do not want to work at it too hard. My favorite finds are classic oldies programs so I will stop on those and listen.

If I hear a lot of static on a frequency. I move on to the next station instead of trying to fine tune. At this point, my log has over fifty stations on it. not bad for a Casual Logger who only started a couple of weeks ago.

My new radio is a Small Portable, not an Ultralite. It is a Sangean ATS-405.


ANNOUNCEMENT: Update to DX Central Live! start time for DST and end of Season 2 is coming!

DX Central - Loyd Van Horn (W4LVH)
 

All,

Two important announcements for our DX Central Live! livestreams on YouTube each Sunday night:
  1. With the change to Daylight Savings Time, we are keeping the livestream start time at 1945 CDT which is now 0045 UTC.
  2. Season 2 of DXC Live! will be ending on April 30th, so that means counting tonight there are only 8 episodes left.  We will also wrap the MW Frequency Challenge for Season 2 at that time.
I am already mapping out plans for Season 3 and hopefully, since I shouldn't be moving again right at the start of MW DX season, we can start a bit earlier than this past year like I had planned. 

I wanted to take a second as well to thank everyone for their amazing support this year of DX Central Live!  Seeing all the folks participating in our weekly frequency challenges; seeing the excitement as people added new stations/states/countries to their logbook after deep diving into a frequency they hadn't spent much time with in the past; it has been exceedingly humbling and heartwarming the response that you all have given us this year.  

See you on the stream tonight:  youtube.com/c/dxcentral

Hey Drifter!

I'm sorry you're not too happy with your an 200. As previously mentioned by others, I'm certain that if (it's not faulty) and you play around with it some more, you'll be more than pleased with the results. I've just been tuning around the AM band on my 'Super UL' Sony SRF-59 during the daylight hours and, thought I'd take a second to record a short video to show the effectiveness of the loop in cleaning up the signal..

All the best, 
Mark

Re: Tecsun AN-200 = Sutekus

Yes the tuning on the loop  needs to be very precise. A touch either way and you loose the peak. It is also pretty critical where you place the radio relative to the loop. With some of my small radios I actually put the radio inside of the loop. Perpendicular sitting right at the bottom. But playing with the distance and orientation of the radio relative to the antenna will make a huge difference. I also bought a Lazy Susan (rotating disk/platter on bearings) to be able to aim the radio and antenna at the same time. Remember the antenna is directional along the plane of the loop. So the edge (the direction the wire is wound) is what needs to be pointed at the signal and the radio.
From Wikipedia "The radiation pattern of a  loop antenna peaks at right angles to the plane of the loop".
I have several of these small loops. When used correctly, and depending on conditions they can make the difference between a copy and none. They are also good for nulling noise and adjacent channels. I have a couple connected to fixed radios (AM/FM tuner connected to a surround receiver) just to null  noise even if just for some local stations. They can definitely be very useful when used correctly. 
Play with it some more, you may be pleasantly surprised.
