history on HF Band
I have made 99,9 %
is mine favorite mode!
The main my hobby in
HF was DXing !
Interest in radio reception
began at the age of 10 year when my father gave me old Radio RIGA-6
(BC HF tube receiver). But it was not working (broken IF and AF stage).
I made simple crystal radio and 0-V-1 later. It was fantastic to hear
radio stations without any power supply and indoor antenna!
I had my first
RadioHam SWL Callsign UA3-135-816
in 1988 year .
I used "Home
Made" direct convertion receiver (only 3 transistors) (RA3AAE
I had many DX SWL
in 3,7 MHz ( VK, ZL and South America).
Direct Conversion Receiver RA3AAE
Russian military receiver R-311
1 MHz-15 MHz IF=465 kHz
Later i have got
old military receiver R-311 - is very simple and good performance
for SWL !
I was first licensed
at 1993 CW and SSB on HF band (first time 160m)
After some time activity
in 160 m (SSB) - i learned CW !
I actively used
many years QRP power in 3,5 and 7 MHz. It was interesting
! I had "Home
Made" tranceiver and short time had old military
radio R-104 (for QRV 3,5 MHz). I used antenna VS1AA and
But the life is too
short for QRP
And in 1994 year i had old military
receiver R-250M (20 lamps) and made the "Home Made"
transmitter to it. About 10 years i used it.
Very good receiver
, but ..... weight
of the receiver with the transmitter is the more 100 kg
I used many Power Amplifiers
, also "Home made" with GI-7B (300W) and GU-43B (1kW).
My antennas for HF was not big
, i used only :
2 el wireYagi
2 el ZL yagi
inv V and dipole
in 3,5 and 1,8 MHz.
Some time i used
2 el Quad in 28 MHz and Loop in 3,5 MHz.
Approximately in 2001 i had
old IC-745. Good vintage RIG. As
i have got for it all filters IF 270/250 Hz for CW and FL-44A
for SSB. I use it as share IF system with the my VHF xvrtr's.
Also i have use
DSP 59+ Timewave - good equpment for receiver weak signal in
strong noise and QRM. Below of DSP59+ you can see my Home Made
integrator for audio signal for TRX1, TRX2 , DSP , SDR and FM
