CW Novice operator :

I am learning CW. If you hear me on the bands in this mode, please consider QRS, sorry for my low speed & mistakes and TU for your patience.


Aprendiendo Telegrafia. Si me escuchas en este modo, transmiteme despacio por favor. Disculpas por adelantado por mi baja velocidad y errores y si completamos QSO, gracias por tu paciencia.




Hello dear radio-friend and TNX for reading my page.


I am David. I have been a HAM licenced since 1994 and involved in radio since I was 16. Previous callsigns were EB4DEH and EC4AJV.


My school was CB. It was there where I learned DXing (234 divisions confirmed)


Nowadays I am active from 80m band to 23cm band (Incluiding 70MHz) in SSB, QRS CW, digital modes and satellites (AO-7, FO-29, ISS, AO-73 and enjoying getting telemetry from other LEO satellites). Operating HF, I like DXing (286 worked DXCCs) and Contests. In VHF-UHF I am quite active in national DX contests (MAF) working our portable station together with a very nice group of local friends. Since 2010, also active in VHF Meteor Scatter mode.


My QTH is in Colmenar Viejo, a city at 895m a.s.l. and located 35 Kms (20 miles) NW of Madrid, in central Spain. Grid WW Locator is IN80CP. Sometimes (especially in summer and at Christmas) I work my second QTH located in the province of Zamora.


Succesfully active in DMR digital system. My ID 2144149 in the Brandmeister network. Thanks to EA7HKA for the equipment, EA1ARW for the advice, EA4FLN for his support setting up my radio and EA2CQ for his "DMR para novatos" tutorial.


Used colective and special callsigns: ED4URJ, ED1R, AM04SG, EF0F, EG4TOR, AN400M, EF4HQ...

QSL is OK via bureau or direct to the adress mentioned above. No green stamps neither IRCs needed. Your QSL is always welcomed


Paper QSL is always prefered but I upload regularly my log into LOTW and I answer all received EQSLs. HRDLog.net QSLs are not useful for any award or program I could be interested on, so I dont check them and I dont answer them.


Best 73 de David EA4SG



I confirm all contacts without contribution neither SASE, but I DO NOT ANSWER DUPLICATE QSLs. I ONLY CONFIRM EACH STATION ONCE IN EACH BAND AND MODE, expect special events and outside activities QSLs. Thanks for understanding.


Confirmo todos los contactos sin necesidad alguna de contribucion o SASE, pero NO CONFIRMO QSLs REPETIDAS. SOLO CONFIRMO UN QSO POR ESTACION, MODO Y BANDA, con excepcion de QSLs de mis eventos especiales o mis actividades portables. Gracias por la comprension.
