Winter has arrived in northern Sweden at my QTH in Boden (KP05vs). This morning the outside temperature was -10 C.

From the Swedish Post and Telecom Authority (PTS) I got a permit to use the 60 m band for ham radio during January 23 to June 30 in 2013. See previous post here. Above is my log for this period showing my few QSOs and Skimmer stations reports. I never heard any North American station and no Skimmer station there reported my sigs. I was using an Elecraft KX3 transceiver (5-10 W) and a very low hanging G5RV antenna. My QTH is in northern Sweden (KP05vs) not so far from the Arctic Circle.
Note: The LA1... station above is LA1IC QRP. Distance is in km.
One week ago I bought a ca. 10 years old ICOM IC-746 100 W transceiver. It can transmit on the 60 m band, but the in-built automatic antenna tuner cannot be used on that band. Instead it is possible to use a separate manual antenna tuner. I first checked, with a 50 Ohm resistive load, that an output power of 100 W could be achieved.
I have now got a new fixed station permit from the PTS, October 17 to March 31, at my KP05vs QTH.
So on October 18 I checked my new rig connected to the G5RV antenna and with an output power set to ca. 50 W. No QSOs but Skimmer reports as below. I heard LA, G and OZ stations, but they were on frequencies not allowed for me to use.
I will soon hang up an end-loaded 1/4 wl wire for 60 m and with a 9:1 balun for a 50 Ohm coaxial feeder. It will be higher above ground than the G5RV and hopefully this will work better.

Outside my kitchen window I have a small discone antenna. It is a Diamond Super Discone Antenna Type D130J. The height of the top element incl. the loading coil is ca. 0.7 m. The receiving range is 25 to 1,300 MHz and transmit range, also according to the spec, is from 50 MHz and up. I have found that I also can use it for transmit/receive from 14 MHz and up. I have even worked QSO´s with low power on the the 40 m band.
When back home after one month in northern Sweden I noticed that part of a green plant on a nearby wall, ca. 1.5 m away, somehow had found its way to the antenna. It started to grow on one lower element and it is now above the top element.
I was curious about how the antenna would perform now, although bad summer conditions. My Elecraft KX3 with 10 W output autotuned to a low SWR on 14 MHz. Running CW CQ´s gained no answers, but CW Skimmer receiving stations received my signals. I was astonished that see on the Reverse Beacon Network that the skimmer station of VE2WU near Montreal could copy my CQ. It must have been GREEN POWER! :-)

The IOS info app Interplanetary 3D Sun is a very useful to predict Auroras.

This photo shows my low hanging 31 m G5RV wire antenna at my SM0FOB/2 QTH in northern Sweden. Gubben, my Second operator is a young Svensk lapphund (Swedish Laphound), only 4 1/2 months old.
This is the antenna I use on the 5 MHz band. Although its low height it is possible to have "DX" contacts with it. Recently, with 5 W output from my Elecraft KX3 transceiver, my CW CQ signals was heard by a skimmer station on Iceland (TF4M, Distance 2,030 km, 13 dB s/n) and another one in Germany (DL1EMY, Distance 1,838 km, 8 dB s/n). Later with only 1 W output the skimmer station DL1EMY received my CQ with 2 dB s/n.

Since December last year it is possible for Swedish radio amateurs to apply from the Swedish Post and Telecom Authority (PTS) for a 6 month license, permitting the use of four 3 kHz channels in the 5 MHz band. These channels are:
All transmit modes are allowed. Maximum output power allowed is 100 W PEP. Mobile operation is not allowed. The license is valid only for one fixed location, i. e. your permanent QTH.
My ordinary QTH is in Stockholm. I spend a lot of time as SM0FOB/2 in Boden (KP05vs) in northern Sweden. This QTH is not so far from the Arctic Circle and the latitude is the same as for Iceland as a comparison. I thought it could be of interest to get some experience from this new band; like how the propagation changes between day and night time and different seasons, what distances can be achieved with low power and simple antennas etc. . So I applied for a license and got it one week ago.
You can see my result until now in the screen dump above (click on it for a larger view) from my logbook. I found that the Reverse Beacon Network (RBN) is a very useful tool as the "skimmer" receiver stations decode calls together with received signal strengths.This information is automatically sent via Internet to the RBN net. Another useful tool is to listen for beacons. I will try that later.
My twin brother Leif, SM7EQX has also received a license. He lives in Ronneby in southeastern Sweden (JO76pf). The distance between us is 1,117 km. I do hope we can have daily contacts between our KX3s.
This is my SM0FOB/2 station. The radio is an Elecraft KX3 QRP HF (incl. 50 MHz) 10 W transceiver. The transceiver control and logging software I use is Ham Radio Deluxe v22.214.171.124. The laptop is an ASUS with an 11.3" touch screen. OS is Windows 8. The laptop is HDMI-connected to a 27" screen.
