PeO, SM5EPO, reports that Västerås Radioklubb, SK5AA
, are celebrating their 70 anniversary. To further mark this event the Swedish telecom regulator, PTS, has granted a 4 m license to SK5AA from 1 November 2013 to 31 December 2013, both dates included. The operating frequency is 70,1375 MHz, with a 25 kHz channel spacing and maximum power is 20 W ERP. Operation has to be within 40 km from Högsbo 536, SE-740 45 Tärnsjö.
PeO, expect to use his Elecraft K3 with an OZ transverter running 20 W ERP using a 4 el yagi at 6 m above ground from JP80MC.

Thanks to all who joined via radio my Nordic trip, and for those who patiently wait for each single QSO made during this event. Summary is: 21 more or less wanted squares mainly in 4 m and 6 m, 11 IOTA Islands along the Finnish and Norwegian border. During the trip 287 QSOs on 4 m, 202 QSO on 6 m MS/CW/SSB and more than 4800 on HF was made, unfortunately not all stations worked due to aurora, bad weather or equipment malfunction, but that's the life in the field. Trip distance reached 10100 km in 30 days of journey.
QSL card are on design stage, anyone who is interested please take look on my website
. Due to some missing cards and letters with SASE in my 20+ years radio activity, decided to do it modern way - easy and secured PayPal. If you have enjoyed my DX pedition and feel free to help make another one in the future - with small donation. All others QSLs will go via bureau.

Linear Amp LAUNCH all new GEMINI solid state Linear Amplifier range.
Linear Amp are pleased to announce the launch of the GEMINI all new linear amplifier range.
Designed, manufactured and assembled entirely the UK, the GEMINI linear amplifier is an all new solid state linear amplifier with 300 W output available in 6, 4 and 2 m versions.
Designed to fill a market gap between the low power outputs of transverters and smaller rigs and the 1kW plus amplifiers that not all users want or can afford the Gemini range combines low drive requirements with instant on solid state performance. Furthermore GEMINI is a complete turnkey solution incorporating an integral 50 V linear power supply so no external PSU is required.
First production will be a with 4 m and 6 m version to be followed with 6 m (50 MHz) and 2 m (144 MHz) versions.
- Solid state instant-on design
- Integral 50 V linear power supply
- Advanced cooling design ensures high duty cycle operation for MGM modes with low fan noise
- In-built sequencer
- Full protection against overdrive, high SWR and over-temperature
- Ultra compact all aluminium chassis measuring just 270 w x 300 d x 120 h mm
- Input drive levels from 3 W – 25 W can be specified
The first public appearance of GEMINI will be at the National Hamfest , Newark on 28th/28th September on The DX Shop Stand. First deliveries of the product will be in October. The price is 849 GBP incl. VAT. Full details are available at www.linearamp.co.uk
or by calling The DX Shop on 01588 620126.

Emanuele, IW9GDC, reports that the IW9GDC/B beacon in JM78SD
is now up and running on 70,092 MHz using 7 W to a Big Wheel. The beacon is frequency and time locked to GPS and transmits PI4 (call) + CW ID (call and locator) and carrier. Please send your listener report to Emanuele.

Jean-Jacques, ON7EQ, writes that the Belgian national telecom authority has granted expansion of frequency band and power as per 14 August with immediate effect. So the Belgian allocation is now
69.950 MHz (max 10 kHz wide) and 70.190 MHz to 70.4125 MHz. Also the maximum power has been increased to 50 W.

For your information , our national (Belgian) radio administration has launched a public enquiry regarding the extension of the 4m band and an increase in power. For time being, we have 69.950 MHz and 70.200-400 MHz with 10 W ERP, this would be extended to 70.190 - 4125 MHZ and 50 W power output at TRX - hence offering new possibilities for DX-ing, especially towards EA, Iceland, ... These amendements were proposed by the UBA and all parties have the opportunity to enter their comment till 27 June 2013.
On the other hand, a 4 m beacon is planned in central Belgium, application for the license is being processed, equipments are ready to go on-air! Frequency will be most probably around 70.222 MHz, as operation within the IARU beacon segment was refused by telecom authorities, even as a single exception.

Jemtlands Radio Amatörer has gotten the first Swedish permit
to operate on 70 MHz (4 m) from the 2013 VHF meeting 31 May to 2 June 2013. Details are still being worked on for when and how we will be QRV but the following data is set.
Frequency: 70.1375 MHz
Time: During the meeting (more information will follow)
Operating modes: Primarily meteor scatter (unless good sporadic E).

Good news, as of 23:30z on May 8, 2013 this year's North American 4 m Eskip propagation beacon on 70.005 MHz is now QRV. The FCC Experimental License for one-way transmissions only was granted the day before. So I did my best to get the system back on the air and is now operational. The technical specs are the same as they have been in years past. TX freq is 70.005 MHz and is GPS locked. Emission mode right now is CW. (There are plans to add JT65 later in June thanks to the 4 m OZ-land ops!)
To review: the new callsign is WG2XPN. ERP is 3 kW from a 3 ele yagi at 15 m AGL. QTH is FM07FM. Yagi is aimed at 60° true to the EU. This callsign is valid for a full 2 years and can be renewed which I plan to do when it is time to do so.
Please understand that if there are ANY reports of QRM to the US domestic TV service, the beacon must QRT. The site is also located inside the US National Radio Quiet Zone where much radio astronomy work takes place. They too have QRT authority over my operations. There have not been any QRM issues in years past and I wish to keep it that way. There is really no chance that a 4 m amateur band will exist in the US for as far as anyone can see into the future. So for the pure study of TA Eskip, this beacon exists. My personal goal is for 2 m TA, and this helps gauge the likelihood of a possible 2 m TA path. Much remains to be learned.
I again want to extend my thank you to the Society of Broadcast Engineers and the FCC's OET office for yet again letting such one-way beacon operations take place in the US.

Emil W3EP writes: Several of you have asked about North American stations interested in 4 m to 6 m cross-band QSOs. I have polled an array of East Coast 6 m operators for several years and have compiled this list of stations with 4 m receivers in place ready to make cross-band QSOs (arranged north to south):
VE2DFO in FN25VJ
W1IPL in FN54FC
K1SIX* in FN43AD
W1JR in FN42EV
W1JJ* in FN41GP
W1XX in FN41EJ
W3EP* in FN31VP
WB4SLM in EM82DP
KE4WBO in EL96VW
* Have made 4 m - 6 m cross-band QSOs
It would be nice if there was more activity on this side, but so far active interest has yet to spread. Perhaps some of you can circulate this list North Americans a bit wider in Europe, No doubt the ON4KST Region 2 chat page will keep everyone informed. I will certainly be making SSB calls near 50.185 when conditions are favorable and will listen around 70.185 initially, CW preferred.
Best wishes for the coming Es season!
