6000km+ TEP opening on 144 MHz from the Caribbean to S America - 19th Jan 2022


19th January 2022: It was interesting to see that that there was a TEP (Trans-Equitorial Propagation) opening on 144 MHz between the Caribbean and South America. While the opening happened at 01:00 UTC on the 19th, the time for the stations concerned was about 8pm on the evening of the 18th.

The maps above shows the opening on 144 MHz with distances in the region of 4,400 to 6,143 kms being recorded. To put that in context, the distance across the North Atlantic from Ireland to Newfoundland is about 3000kms so the longest contact from Buenos Aires to the Dominican Republic is over twice that distance.

LW2DAF: Diego, LW2DAF in Buenos Aires, Argentina reports that his contact with HI3I in the Domican Republic was a personal distance record. Diego was using the Q65B mode and the log from PSK Reporter is shown below...

FG4SU on Guadeloupe seems to have had a good path into Brazil and was using FT8 instead.

You'll notice from the map above that the TEP signals at 144 MHz tend to stay close to 90 degrees relative to the Geomagnetic equator. The paths tend to run parallel to each other with stations in the Dominican Republic & Curacao working Argentina and Puerto Rico & Guadeloupe working Brazil.

While TEP openings are normally associated with the equinox period, it's interesting to see one an opening on 144 MHz in mid-January.

144 MHz TEP openings from Brazil to the Caribbean continue - 23rd Sept 2021


Following up on my previous post, the TEP openings on 144 MHz from the Caribbean to Brazil are still happening. On the 23rd of September 2021, there was a modest opening from FG4SU in Guadeloupe, FM5CS in Martinique and 8P6ET in Barbados to the south of Brazil.

The distances were all in the region of 4500 to 4700kms which is typical for Trans-Equatorial Propagation.

Day 2 of Trans-Atlantic opening on 144 MHz between the Canary Is and the Caribbean - 20th Aug 2021

Following on from the trans-Atlantic opening on 144 MHz on the 19th, the tropo duct between the Canary Islands and the Caribbean remained open on the 20th of August 2021.


César, EA8CXN in Tenerife seems to have had the best path to the Caribbean with seven different stations in Puerto Rico and Guadeloupe listed on the PSK Reporter website.

These are the reports for the EA8 stations...

Video clips: This first one is an SSB contact between EA8CXN on Tenerife and KP4EIT in Puerto Rico...

This second video clip is of Franck, FG4ST on Guadeloupe working EA8CXN...

It's pretty amazing to when you consider that you are listening to a trans-Atlantic signal on 144 MHz.

Distances: Like the previous day, the distances were in the region of 4800 to 5200kms.


It's interesting to see the distances plotted out on a map and how parts of North & South America are closer to the Canary Islands than the Caribbean.

Propagation Mode: The map below from Pascal, F5LEN shows the predicted tropo conditions...


It looks as if there is a large tropo duct across the Atlantic. It may well be that a layer of dust from the Sahara may be playing a role in this opening as well as it travels west.

Update: Day 3 - 21st of Aug 2021
This day was similar to previous days except the number of stations was lower.
