Re: Central American update

Dan Goldfarb
 

Members,
Just to be totally clear. I will complete the remainder of Central America. This will allow me for that tab to actually remove 2 columns on the Active spreadsheet.
Once this is complete I will upload the two spreadsheets.
At that point I will start work on South America.

Central American update

Dan Goldfarb
 

Members,
I am pleased to report that at last my gigantic task to modernise the Mexican data has been completed. Within Active I have 382 lines only relating to stations at 1kW or above in that country. Within Inactive or Closed there are no less than 439 Mexican stations listed. This includes a number of light orange coloured rows which cover Phoenix stations where new callsigns and slogan names have already been lodged.
I have moved onto Nicaragua. I can advise that thanks to spotting an ID on Google Maps I now realise that the mast found at 12° 06' 42"N, 86° 15' 49"W belongs to Radio Nicaragua on 620kHz.
Having done more than half of the Central American page just by finishing the Mexican entries it will not be long before I can upload the spreadsheets for you to enjoy. After that I will move onto South America.

Members,
Thank you Mauno.
Time will tell re the eventual use of the frequency.
This is thinking way outside of the box but ...
I wonder if All India Radio is wanting to use the Chinsurah site to broadcast to Myanmar? Either that or maybe even starting of broadcasts in Rohingya???
This depends on the priorities of the Indian Foreign Service. It's priorities right now will be focussed primarily on Kashmiri / Pakistani issues. To this extent re-opening of 1134kHz is a surprise.

I have tried to ask everybody there, but no reply. Even the tests have stopped now. Maybe they will use Maitree between 1800-2400 or so.

Members,
With the reactivation of the very important 1000kW station on 1134kHz in Chinshurah I am trying to check the latest developments.
594kHz is already serving the Akashvani Maitree service of All India Radio to Bangladesh.
Perhaps locals can advise on what service is eventually allocated to this super power station.

Members,
Just to keep you updated I am making some progress.
I have separated over 300 Mexican stations which have now been closed.
The differences between columns for Active and Inactive or Closed make the job of moving such a large number of stations from one spreadsheet to another slow going. Once these stations are away from my Active spreadsheet I can complete the work on the remaining active stations.
There is yet another colour now in use on my spreadsheets. It is light orange. This refers to what are essentially Phoenix operations.
In these cases the same frequencies and masts will be reused. What is changing is the licence and the names of the station. For Mexico 17 stations have already alerted IFT and have registered the new names and call signs. I am still a little unsure where to put these entries. Once the new identity is in use and the stations are broadcasting they will of course go onto Active. I have temporarily placed them in Inactive or Closed. I will try to keep an eye on Mexican DX websites to see when the reactivations take place.
Fortunately once Mexico is completed it will be a speedy task to have all stations on the Central America tab ready for Geo-Hack input.

Members,
A change which is very new and may not have caught your attention will need to be recognised in my spreadsheets.
With effect from today both Leh and Kargil are no longer in Jammu & Kashmir. They now are within the Union Territory of Ladakh.
This will mean a small change in WRTH.
i have made the changes on the Active spreadsheet.
If any member knows of other towns within Ladakh which have or had mediumwave stations please let me know.

Hi Dan,
the coordinates for this station are wrong on 20190719MWActiveSitebased2.xlsx!
They are pointing to a place in Moroccan soil. EAJ-46 ex-Radio Ceuta has been
broadcasting from the early 30's from Monte Hacho. This could be the mast:   
35°53'51.16"N   5°17'28.58"W

Mexico XEW

Dan Goldfarb
 

Members,
After a lot of investigations I came across the IFT technical specification for the move of the iconic station XEW in Ciudad de México.
The reason for the move away from Ex-Hacienda Coapa is that the old spot with the tall antenna has been given over to a football (soccer) pitch.
At first I suspected that the new site would be where XEX 730kHz  is housed which is in Los Reyes Acaquipan (at 19 21 39N 98 59 34W). This is wrong.
Having dug out the technical specification - like the long lamented AFSCA Argentinian documents - I followed the coordinates given there.
A site has now been identified at 19° 21' 55"N, 98° 57' 28"W or 19.365172, -98.957773 there is a mast which is so new that it can only be seen through the latest image using the Historical feature on Google Earth. From that monopole the station now is broadcast at the new 100kW output. The area comes under La Paz as the title. I will attempt to upload the specification for this move into the Files part of this website.

Members,
Lots of conflicting pointers exist re Léon 590kHz XEGTO.
There is a big rural space between Léon and Guanajuato to its East.
The focus seemed to be around Arperos.
The reason for this alert for you is that the monopole is literally in the middle of nowhere.
This is very much a mast which I stumbled across. The size matches the low frequency and there is good resolution on maps.
It can be found at 21° 06' 29"N, 101° 25' 18"W or 21.107934, -101.421774. This spot comes under the label of Los Gómez.
You could well receive other notifications of finds from Mexico over the next weeks.

Hi Dan

 

I just struck it lucky, I merely or as it turned out merrily dropped the street view pin on the map and it happened to be opposite the mast. When I am mast hunting I always use the street view if it is available.

 

Keep up the good work

Members,
Slowly there is movement to ensure that the knowledge about AM stations in NZ is nearing towards 100%.
A fascinating discovery by Paul Rawdon covers the setup for Magic on 1386kHz and The Wireless Station on 1530kHz within the Hawkes Bay area.
With some skill the existence of a series of wires attached to a TV/FM tower at 39° 26' 28"S, 176° 52' 56"E or -39.607788, 176.882098 was identified.The setup can only be seen through Google Streetview either through Maps or Earth. It nearly has the appearance of a double T-Shape! Quite complex.
Secondly I can report (via Asiawaves) that Ranfurly 729kHz is at  45° 07' 30"S, 170° 04' 35"E or -45.124913, 170.076303. It is one of those frustrating finds (these often take the longest to find) where all that you can see is the shadow. However a circle does appear around the "smudge" in the most recent Google Earth image. This adds to the likelihood of the mast appearing soon in images. The existence of a tube mast holding up a dipole at the studio pointing West plus the RSM vague suggestion of a location West of the town makes the find an almost perfect fit around the evidential clues.
To wrap up on another point  Scott confirms that we will be pretty close by having 30 June as the end of use of Chicago Itasca  WBBM 780kHz and 01 July as the start of sharing with WSCR at Bloomingdale. The very tall mast and tower set at Itasca was demolished with great speed so that commercial development could begin on that valuable plot of land.
All in all it has been a very rewarding week re finds to boost my spreadsheets. My Mexican work goes on. Although I am still at an early stage I am surprised at how many of my coordinates - entered several years ago - still appear to be perfectly viable. For others which have disappeared I am finding some interesting clues on the recently revamped REC website.

Hi All

TWR are installing a second MW transmitter at their site in Parakou, Benin.

Some details here, but it will be directional and targetted at Nigeria especially the north of the country.

https://twrafrica.org/see/news/634-oasis-in-a-barren-land

I will attempt to get further details to pass on.

Please take a look at the 2 spreadsheets found in the Files part of this website. At least I am nearing the stage where black type entries can be replaced by blue type underlined ones in the Live column.

Re: New Zealand

Dan Goldfarb
 

Apologies but once the Groups.io software goes into Attachment mode the rest of the post stays in that setting.
There are very minor discrepancies between station names used by Steve and those on WRTH. I have retained the WRTH names on my spreadsheet.
Could Paul Rawdon possibly help me out to see that the above finds its way onto the next DX Times - subject to deadlines?
At last the arguments re apportionment between the two masts have been settled.
