At the moment, there seems to be an TEP opening on the 144 MHz band every evening between South America and the Caribbean area. The evening of the
6th of February was no exception with an opening just after midnight UTC on
the 7th (~8pm for the stations involved on the evening of the 6th).
Brett, PJ2BR in Curacao reports working stations in Argentina with just 10-watts into a 3-element Yagi!
PJ2BR writes... "This is an unusual evening. Was able to work @LU4DJC,
@LU1FAM and @LU2EPO on 2m Q65. What makes this unusual is, made the contact with 10W and a 3 element Arrow yagi! My signal was also rx’ed in Uruguay. 5461 Km on 2m 10W!"
Many people will be familiar with the Arrow dual band antenna which is
often used to work the satellites.
5,461 kms on 144 MHz with just 10-watts in to a 3 element Yagi is pretty amazing. Remember that this is via Trans-Equatorial Propagation and not via some satellite passing over.
It is also a LOT further than the 3000kms or so across the North Atlantic
from Newfoundland to Ireland which has never been bridged on 144 MHz.
To complete the contact, PJ2BR was using the Q65 digital mode...
In this screen shot, LU2EPO in Argentina was hearing PJ2BR at -16dB which
is just below what is detectable by ear.
There are the spots from the DX-Cluster for the opening...Spotter Freq.
