Wednesday 2nd February 2022: Another day, another big Trans-Equatorial Propagation (TEP) opening on 144 MHz between South America and the Caribbean. The map above shows the parallel paths from Argentina to Bonaire, Curacao & the Dominican Republic and from Brazil to Puerto Rico, Martinique, Guadeloupe and Trinidad.
The parallel paths are due to the fact that at 144 MHz, TEP signals must cross the Geomagnetic Equator close to right angles. At lower frequencies like 50 MHz and 28 MHz, the angle can be much wider.
I have included a list of the spots from the DX Cluster at the bottom of the post.
Video: Brett, PJ2BR in Curacao has a nice video clip of a LW2DAF on 144.300 MHz SSB.
This was the SSB contact with Diego @LW2DAF Slightly over 5.000 Km away. pic.twitter.com/oeHCTVQG3r

This second video clip is of Diego, LW2DAF in Argentina having an SSB contact with HI8GSP in the Dominican Republic on 144 MHz, a distance of about 6000 kms.

Caribbean: This is a map in closer detail of the stations in the Caribbean...
The reason I include this is that it shows the usual stations and countries in the Caribbean that are taking part in these TEP openings on 144 MHz. The map also shows all of the other countries where there doesn't seem to be much if any 2m activity.
The map just got me thinking... could more people in the Caribbean get active on 2m?
Chile? Cuba? Columbia? Central America?... In other previous posts, I've looked at TEP openings on the 88-108 MHz band between Chile and Columbia.
Q. Do these reach 144 MHz as well? Is the lack of contacts just because there are no stations from some of these countries on 144 MHz?
CO8LY was mentioned on the DX cluster but I couldn't see any record of a path on the PSK Reporter website.
432 MHz??? Lots of questions today!
Q. If there is a really good TEP opening on 144 MHz in South America, can it reach 432 MHz? It's been done before between Zimbabwe and Greece.
Q. Is anyone trying to make a 70cms contact via TEP at the moment?
Q. Is it only possible at the peak of the solar cycle?

I am in 8P5AB and I am willing to set up skids on 70cms using my 2 70cms 11 ft Circular Polarised beams
