Muutamat näistä RX-asemista ovat ihan kelvollisia - olen käyttänyt mm. 80
antennien testaamisessa.

Mielenkiintoiseksi DX äijille nämä tekee se että nyt ei tarvitse yrittää
kuunnella QRP DX:iä esim Karibialta kotona, netti-vastaanottimilla se käy
vaivattomammin, eikä tarvitse rakentaa erikoisia kuunteluantenneja.

Jospa tonne Pacifikkiinkin tulisi muutama VFO:lla varustettu, niin voisi
edes yrittää kutsua YJ0ADX:ää Hi.
