WAP has received some notes sent by Alejandro LU8YD the operator at Esperanza Base (WAP ARG-Ø4) in February and March 2023 and at LU4ZS Marambio Base (WAP ARG-21) in April 2023.
Alejandro wrote: In the austral summer of 2023 at Esperanza Base (WAP ARG-Ø4) we did operate LU1ZV on all bands (160 trough 6 meters) on SSB, CW, FM, FT8, FT4 and Opera, together with Juan Carlos Benavente LU8DBS and Juan Pablo Arena LU6DX .
According to the information in our hands, the 2023’s Ham radio activity would have been the largest 
operation from Antarctica in bands and modes with extraordinary results on 6 meters and perhaps the first to operate on FT8, FT4 and FM on 29 MHz in addition to the new 60 meter band. All the hamradio operation are performed from inside the building of LRA36 Radio Nacional Arcangel San Gabriel, using its rombic antenna
On the other hand, we have participated in two international competitions; the South American Lighthouse Weekend and extensive research work on Antarctic radio propagation. We left a 6m radio beacon running 24/7 (24 hours a day, 7 days a week) to study propagation. The LU1ZV February – March operation reached the approximate amount of 13,000 QSOs. April 2023 operation, add other 2500 QSOs.
Currently and for a few more months, LU1ZV is only operated by LU8DBS, Juan C. Benavente on SSB 
and FT8. The LU1ZV activations have the support of the “Uniendo Voces” a project of the National University of Quilmes (Buenos Aires province).
Just about LU4ZS, LU1HCQ operates for the remainder of the year 2023.
My professional assignment in Antarctica Argentina, says Alejandro, was to work on the improvement of LRA36 station and to assist in the maintenance of Antarctic radio communications of these two Argentine bases.
Just to remind the Readers and Antarctic hunters the LU1ZV/B 50 MHz radio beacon, in its CW & FT8 multimode modality at 50.313 MHz.
