Hello everybody

i got my lis after a little home study in April 1997 and i am on air since 1998.

mainbands are 144 and 50 MHz , some operations on HF also .....

but my focus is 12m ,10m and Topband 160m

QSL informations see down below , thanks .....

+++ sniff get now more than 10 opened direct QSL cards last time :-( , i don´t know why ... no Call on the letter but i will be answer it anyway ! +++

4m Card´s for special permit in 2015 are printed and on the way to You laugh

73 es DX de San (Sandro)

144MHz - GS35b Tube Amp. runs up to 2kW with 80 to 100W input

Equipment at grid locator JO72en


Elecraft K - Line @ KRX3 >> Kit´s are homebuild in some hours << works with a MD-100 with electret cap and a KENT Twin Paddle

Headset is a KOSS SB40 same as YAMAHA CM500

YAESU FT-847 / 70 Mhz mod 4m LNA inside / MD-100 modified with a electret cap and a KENT Twin Paddle ( 1st. generation )

1.8 Mhz - 22m + 2x 15m T- Antenna using 4 times elevated radials in 3m high

1.8 Mhz - full size half wave dipole @ 600R - 100mm ledderline & full symmetrical antenna coupler see picture down below

1.8 Mhz - RX Antennas in BOG-style terminated with 220R into a 1.5m long copper groundrod

W7UIV - Preamp is avaiable if needed also ,small size PCB´s are from Karel OK2ZI

50 Ohm feedpoint match 1,5m above ground from my 160m T-Vertical - 170mm inner diameter made from 8mm aluminium wire

the next picture shows a screenshot  from the 1st 100 kHz of 160m . that´s my noisefloor during primetime of TV .... still i am happy hihi , sometimes  1810 to 1824 not usable !  here runs a BRAS3/RS-10  hyperbel navigation system from UA2 or SP - Navy on Baltic Sea Coast sad sometimes peaking S7 at normal condx , if it is offline thats the best time for DX ... maybe you can work between 2 tones with a good CW filter wink hope to see you there as next !

the yellow line shows the the normal signal level - blue line is the measured peak level

<<< QSL Information >>>

LotW ( preferred ) all Log´s from 1998 until now online ... uploads every month if possible

QSL via Bureau from 2015 until open end .... incoming Cards will be answered only

QSL direct EU <> EU only a QSL Card is needed !

QSL direct EU<> outside EU 2USD only Shortwave , 50 MHz/144MHz needs a QSL Card only

all SWL-Card´s will be answered so fast as possible too !

paper QSL´s until 31.3.2008 are out via DARC Bureau !

* after a big trouble with sending the rest of my outstanding QSL Cards until 31.12.2014 , all on the way via DARC now too .....

                                                       * * * Many thanks for your patience * * *


2007 i lost one part of my primary log from earlier activity´s on 80m until 17m , a big lightning in my antenna area destroys a lot of equipment .

i have to try to rescue it , but i was not lucky ! until this time some QSL´s ( 2003-2005 ) are going out , but some ones not ..... SORRY !

so sorry that i can sent activ a QSL Card for HF operation, but all incoming Card´s will be answered somehow ....
