Usage a Vertical Delta Loop Antenna (loop has 83 meters) for 50 MHz band
12/02/2021 12:49
I tried to use my Delta Loop antenna 83 meters long for 50 MHz band. According to MININEC program it could work relatively good there to lots of directors. There was only one problem with an impedance matching between my TRX and the antenna. My SW MFJ Antenna Tuner because does not work on 50 MHz....
New Equipment of OK1DN

Because of the fact that I was not able to obtain a needed pair of bipolar transistors (PP100 or 2SC2879) for my PA ALS500M(XCE) (the world situation is not too good nowadays of course) I decided for following solution. I bought a new small TRX (with 200W CW output power) TS-480HX from...
OL90 activity - my result
30/05/2020 13:11
I operated two OL90 stations/callsignes – OL901AA and OL90CRK on 14MHz band in CW mode. I started on May 19th 2020 and finished on May 29th 2020. As OL901AA I made 588 QSOs and as OL90CRK I made 1635 QSOs with 67 countries of DXCC. Propagation conditions ware not too good and I had only 100W power...

The 90th anniversary of first radio amateur licenses in former Czechoslovakia
C.A.V. with C.R.K. (as co-operator) has organized the Celebration Activity of OL90 stations on HF and VHF HAM bands – from May19th to May 31st, 2020. I am operating OL901AA (Mr. Miroslav Shaferling, OK1AA, was the...
Experience with FT-8
04/03/2020 14:03
My feeling about my cca 2 month operation of FT-8 mode on 2 meters (144174 kHz) is a little embarrassed. I “made” some relatively long distance QSOs (my QTH was not too good for VHF) like F,YT,9A, S2, HG and all neighbor countries. Propagation conditions were also not too good. But I was not too...
FT-8 Mode on 2 meters
22/12/2019 14:45
I am starting my operation in FT-8 mode on 144174kHz (2 meters band). I use my Digi Interface and MSHV software by Christo, LZ2HV. I have made QSOs with the Czech Republic and neighbor countries (SP,DL,OE,OM) and France (over last two days). The propagation conditions on 2 meters are not too...
My comeback to VHF - 2 meter band
01/12/2019 22:37
After 10 years I am coming back to VHF – 2 meters band because of very poor propagation conditions on HF bands now. My QTH is very good for making QSOs on short waves but not too good for VHF. On the other hand although the QTH is located in a forest and on a slope of a hill (ASL is 400...
HOLICE 2019

One year has passed. The international HAM-FEST Holice 2019 has come (August 23rd – August 24rd).
I visited the one at the first day (yesterday). I met HAM friends like every year (some of them /face to face/ after more than 50 years /we are so old, what to do … /). I also visited the stands...
Digital MODES - My New Operation
04/04/2019 21:45
I can say that I still prefer CW to other modes. Unfortunately my PA is out of order now. Because of that fact and really very poor propagation conditions on SW I have started my operation on DIGI MODES with PSK31 and PSK63. My Interface (between TRX IC7410 and notebook HP450) is home made...
