Ham Member Lookups: 20512


Few words for me:

I started with the hobby since 1987 in radioclub LZ1KNP and later for few years I become a member of student radioclub in Sofia LZ1KDP and had been licensed in 1991 as LZ3SF.

I haven't been active for sometime on HF and recently /summer 2010/ I bought an ICOM 7000, September 2011 - FT990.


My rigs could be seen on the primary photo:

FT990 and ICOM 7000 - both are 100w, no PA

Tunner: MFJ-945E used only with ICOM 7000

Antennas: home made kind of verticals, depends on restrictions.


Main ham activity is HF DXing - for 3 years, since I get back in HF ham radio,

I was able to work with 100w 245 DXCC entities on SSB and CW - mixed, worked 8Band DXCC - 80m-10m:


2016/2017 from Bulgaria I made similar vertical to 2015 - multiband homade wire vertical, the difference  - I was using 2 fiberglass masts for one vertical (only 1 coaxial cable for all wires). Frist fiberglass mast was 15m and there were only 2 bands - 40m with coaxial trap and prolonged for 160m Inverted L. Second fiberglast mast was 12.5m for 80m,30m,20m,17m and 15m - with coaxial trap for 30m, proloneged with wire for 80m. Initially the idea was 40, 80 and 160 to be on the same mast, however the traps were very heavy and the 15m was looking like Inverted U with vertical side up to 10-11m only. For the first time ever on 160m - good satisfaction with USA and VK with some EU countries - total 23 countries for few days activity, without any contest. No single radial for 160m - the longest were 2 for 80m, the rest radials were mainly for 40m and 20m. Tx - Icom 7000, Rx antennas: Delta flag and beverage on the ground - only 50/70m long and my trasty Kenwood TL922 within 700-800w.


This year /2015/ for my vacation in Bulgaria I used for a first time home made multiband vertical on 12m fiberglass mast with wires for each band, just 40m/80m was separated with homade coaxial trap /Inverted L for 80m/ and separate Rx antennas: short BOG and Delta flag.  ICOM 7000 + linear amplifier Kenwood TL922 usually within 500-700w range, as driving power didn't exceed 40watts. The result was exelent - TX3X, T2GC and S79SP expeditions were worked easily on lower bands.


From 2011 up to present: Prague

On the primary photo are my radios in Prague, Czech Republic. Currently I am located in Prague. Unfortunatelly, good anntena is a dream now, I am missing Brno and my previous landlord.

The anntena is kind of Vertical - close to metal rain gutter of the house 10m hight mast, shortened to 8m /not much space/ + few short radials, 5 meters each /this is mainly during warmer period - April - Novemebr/. This somehow works not too bad on 40m.

For 80m I am using the same telescope mast and same radials /added more radials, including full size for 40m, mainly in winter season - November till March / I am separating 40m with homemade coaxial trap for 7MHz  - configuration for 80m is Inverted L/. Working not too bad mainly in winter period when the radials are more and propagation is better.


P.S. Now there are only 2 elevated untunned radials /next to the house again/ ~2 meters above the ground, ~10m long - it seems to work reasonably OK even on 80m.

For higher bands, I am using the same antenna with tuner /do not ask me how it's perform, somehow it's working - better on some, worse on another/.

For Rx - Flag antenna in the house /big restrictions here/ and home made Rx mag. loop, phased with MFJ 1026 - still helping alot on low and even on higher bands.


from Prague:



























For 6 mounts with 100w and mentioned bellow antennas from Brno, I was able to work 162 countries:

Anntenas - all of them are home made:


Vertical with 16m /52.46 feet long/ fiberglass mast, ground mounted for 80/40m with 50 radials /from 4m (13.11 feet) long to 20m (65.57 feet) long / with tuner - works almost everywhere. Especially good resaults on 80m,40m,30m,17m and 15m.


Delta Loop for 40m, 7m /~23 feet up/ above the ground , sloping to South-East, with tuner - works almost everywhere.


Wire Moxon for 20m at 3,5m /~11.5 feet/ above the ground, beaming to North-West / from EU this is direction to USA/ - it wasn't working very well due to the low hight, but was still usable.


The following pictures are from garden in Brno winter, 2010:



The delta loop for 40m can be hardly seen on these pictures, but Moxon could be recognized behind the tree /2 white wires, first picture/.




04-07 July.2011 I was in Hungary in Heviz, Nr Balaton lake. I was using home made GP made by fiberglass mast, 10m / ~32.8feet /long wire as director and 4 radials, 5 meters /16.4 feet or 1/8 lamda for 40m/ each.

Thanks for contacts.




















Here are some pictures from the hotel:

The GP could be seen on last picture in full size on the left.


November.2011, during CQ WW CW Contest we were in Chotikov, Czech Republic, small vllage near German border and

I build a full size vertical with 12,5m fiberglass mast and 8 elevated full size radials and an inverted Vee antenna, which allow me to

increase my resault in the contest:


23.June - 30.June 2012 was active from JN11IP like EA3/LZ3SF mainly on 6m with home made dipole on the balcony of the hotel.

Tnaks for contacts.




















25.Aug.2012 - 08.Sept.2012, 24Aug-08.Sept.2013

The pictures bellow are from my home town - Petrich, Bulgaria QRA Loc: KN11OJ

The Vertical is home made with 12,5m fiberglass mast, full size on 40m, with 12 elevated radials on top of the roof on 8 floor's building /28m up/ and ICOM IC-7000

/the pictures are from 2012, when the radials were less/


All the best to everybody,

Looking to hear you soon on the bends,

73! de LZ3SF
