          iz7DJR      op.Nino  -Foggia Italy-    loc.  JN71SL     










My major interests 

QRP                      the_great_challenge    

TELEGRAPHY   the radio essence   

ANTENNAS        a magic world

HM. RTx   endless self learning_school












1971 Qrp stn:  2 tubes tx (2 watts out) , 3 conv.superhet Rx and 14mhz dipole

1972 - South pole QRP qso = 2 watts and dipole    

Not an easy qso, vfo shifting, all tubes stn, surely  not a great performer : sensitivity at least 20db worse  than  modern gears, 1khz selectivity, too much khz - per- turn VFO knob, but some decades_ago it was an hard goal for a new comer... but the little miracle happened breaking the invisible but hard wall_of "thousands-mile-per-watt" leaving me astonished at first, than jumping all around "the radio room" and of course a  sleepless night.

Thanks Nick Makarov for you skill and_pacience.

                               small power and small antennas

TORUS ant: Galapagos on 21 mhz

qrp 5 watts, Borneo island, using 30w 

ZIPPIRO , 54 cm antenna for 40m

built on 2001 and wkd 5 continents_

zippiro-samurai = K8CW from indoor using 14MHz /25w  

outdoor 2,5 w many W / K and JA

10 years to catch this new one...

and 40 years to reach Hawaii...

Over 10 years of time-span, worked 8 times Ken on 14 mhz

by ZIPPIRO-SAMURAI using from 2,5w to 5watts (two-way) _

Zippiro-samurai antenna confirmed its outstanding capabilities

as well as Ken's skill and good receiving site.

Quite hard on 40m : 2way Qrp 5w using a vertical fishing-pole antenna_

and always 2 x qrp with Brian on 10mhz
