April will once again bring radio amateurs a varied offer of KV a VHF pretekov, aj keď z veľkých KV contestov sú v kalendári len Japan International DX contest a Holyland contest. Pre špecialistov na krátke vlny to však neznamená, že by mali zostať doma – aprílový program je plný zaujímavých DX pretekov, ktoré sa konajú v krajinách ako Španielsko, Švajčiarsko, Juhoslávia či Maďarsko, a samozrejme nesmieme zabudnúť na slovenské preteky.
Many of these competitions allow for digital modes in addition to classic CW and SSB connections, so operators dedicated to DIGI operation can find their way. KV enthusiasts will have the opportunity to test their skills from 160 m to 10 m, while in some cases they will compete in special categories or prefix contests.
There is currently a calm before the storm at VKV - the exception is the second weekend of April, when you have your own QTH they will definitely book EME specialists and fans of bands from 6 m above.
