@ SV1XV Maybe you can post the Confirmation QSL Card here?

Sure, when I receive it. It won't be soon, as I requested one via the RSGB QSL Bureau. It may take anything up to 10 months.

I worked GB5RC twice over the past few days, once in SSB and once in JT8, both on 14 MHz.

HF Beacons / GB3ORK JT9
« on: July 23, 2017, 0656 UTC »
The RSGB beacon GR3ORK in the Orkney Islands is back on the air, every 15 minutes. In addition to CW it transmits the message “GB3ORK – 5MHZ” in JT9.

2017-07-19  02:33 UTC    5290.0 kHz  GB3ORK  JT9  "GB3ORK – 5MHZ”
2017-07-19  02:48 UTC    5290.0 kHz  GB3ORK  JT9  “GB3ORK – 5MHZ”

10/11 meters / Re: Digital net on 27635 kHz
« on: June 05, 2017, 0139 UTC »
27245 is also active with digital traffic. On this frequency they use SIM31, but traffic levels are low. 27700 is always busy with SSTV (analog) when the band is open.

Info about SIM31: http://www.sim.on2vhf.be/.

For a few years now, a digital network using ROS mode operates on 27635 kHz. Stations are mainly in Europe and use "Alfa-Tang" style callsings with numerical prefixes. Read more in this article ROS network on 27635 kHz on my blog.

The RF Workbench / Re: RF lowpass filters and inductor orientation
« on: February 23, 2016, 0455 UTC »
cores were T200-2 spaced about 0.6"
Your observations are reasonable: three 2 in cores, 0.6 in apart, with low μ material. It is reasonable to expect some coupling between windings under these conditions as not all magnetic flux is contained in the toroids. Coupling would be less if the inductors were of smaller size, further apart and made of higher μ material.

Huh? / Re: Putin hasn't changed his appearance in 100 years
« on: December 17, 2015, 0655 UTC »
This has led some to speculate on social media that he is immortal and can time travel
Here in Greece we live in a media hype about Putin, who is (supposedly) going to solve all our problems. This paranoia is actively promoted by circles of the Greek Orthodox Church and some fringe nationalist, and has affected a sizeable part of the disillusioned people.

20151214-0318-5352 5-HG7BHB-0007 par SV1XV, on ipernity

Today at 1640 I noticed that CW beacon HG7BHB moved to a new frequency, 5352.5 kHz. Until now it was on 5357.0 kHz. The beacon is located in Rackeve, Hungary, JN97LE and transmits 50 W using a 6.5m longwire antenna @4m.

HF Beacons / Letter Beacon in UHF Milsat band
« on: December 06, 2015, 0540 UTC »
Marco I4IBR / I4-20126 discovered a letter beacon "Z" on 268.05 MHz (UHF), which is the downlink of SICRAL 1B satellite for the Italian Navy. He used an AR-3000 with home-made LNA and a 3 element antenna pointing south.
