*** Update in May 2016 ***

I had my license in 1986 and been active since then without any significant "dropouts".

"D-star" - or DV - with a DV Hotspot is active (SG5RVH B ) on 434,4875 MHz (again :-)). The HotSpot is normally connected to the reflector  DCS010 B. 

I;m active on APRS - see summary below!   *** New mode is RobustPacket on 30 and 20 meter! ***   

In the town Nykoping I have an APRS-digipeater (SM5RVH-2) located very high and which let users up to approx 50 km in radius to be digipeated!

I;m running an EchoLink gateway - SM5RVH-L, node 839597 on 2 meter (145,450 MHz 103,5 Hz CTCSS) and 6 meter (51,4500 MHz 103,5 CTCSS). On the same frequency you can reach the Wires-X network using my node 17159. Note that EchoLink and Wires-X-nodes are connected to each other!  Please do not use the EchoLink <-> Wires-X for long-term (many hours or days) connection between - for example - an Echolink-repeater and another Wires-X repeater!

A Winmor / Pactor 1 & 2 & 3 HF-email gateway is active on 80, 40, 30, 20 and 15 meter. See http://www.winlink.org/ for more info.

I;m also operating a 1200 baud AX-25 Winlink email access-node on 144,925 MHz. Callsign SM5RVH-10. You can also textchat with me on SM5RVH-1 and leave a message in my local mailbox on SM5RVH-2.

Note: There are several stations in Sweden active for AX25 Winlink email access and from the end of March 2014 we agreed with SSA (Swedish amateur radio society) to make the frequency 144,925 MHz a national activity center for Winlink AX25 1200 baud. Please join us and move your local PBBS to 144,925 MHz!!

I have a crossbandrepeater between 145,4500 and 51,4500 NFM CTCSS 103,5 Hz is used on all bands for activating this crossbandrepeater.

I turn on my ATV-equipment (1255 MHz FM) now and then. Please send me an email for sched!

Mobile activities:

Some pictures of the antennas for HF/VHF and UHF-mobile!

Above we can see a whip for 80 MHz (commercial) band, a 144/430 MHz dualband antenna, a HF-mobilewhip for 80,40,20,15,10 and 6 meter and a 144/430/1296 MHz antenna!



Above - My TarHeel antenna for 3,5 - 30 MHz! An amazingly well built antenna - handles all the dirt coming from the roadsurface!


The Tarheel antenna is mounted like this - on the towing eye! Normally - it's mounted on the car all the time!


The grounding of the Tarheel antenna - a very thick copperwire is connected to the chassie of the car! Note: A lot of coppar based anti-oxidant joint compound is added to the chassie connection to minimize corrosion!


Some of the radios inside the car!


At home:

My other equipment at home consists of many coaxcables smiley, a selfsupported 24 meter tower and its "smaller brother" - a 10 meter tower - see pictures below.

A lot of cables in the antennabox. All the coax-cables goes through a panel for grounding the shield of the coax. From the beginning I didn't plan to have this amount of cables but the number increased over the years - now I have to do something about this mess. But I have created documentation telling me all the info I need about which cable is what etc. so I can live with this situation a liitle bit longer ;-).

The grounding of the house consists of a very thick copperwire buried beside the drainage pipe in the soil. The towers has copperwires connected and also buried around the concrete base. All the wires are connected together and create my groundingsystem. The mains input has overvoltage protection circuit which is connected to the grounding wire! And the antennabox - with the cconnectorpanels - are of course connected to the groundingsystem.  



The tower to the right is my 24 meter (approx 80 feet) selfsupported tower including 21000 kg (!) of concrete in the base! Some of the antennas are: Create CLP-5130-2, Cuedee 17 element 70 cm, Tonna 9 element 2 m, Fritzel FB-33 (fixed in 310 degrees), Cushcraft A3WS (fixed in 310 degrees) - incl. 10 MHz, 2 * Icom AH-7000, Diamond A502HB 2 element 6 mDressler ARA-2000, Vargarda 6 element 2 meter (fixed in 320 degrees), a 1/9-transformer connected to a 40 meter wire stretched out 3 meters above the ground etc. A Tennadyne T-10 is waiting to be applied on the top of the tower on a Daiwa MR-750 (3 motor) rotator. 


This is my small selfsupported tower (10 meters high)! From the top - FlexaYagi FX 2317 - 48 element for 1296 MHz, The second antenna is a combination of a HyGain 103BA, a MFJ-1796 (which was modified in to a MFJ-1175) and two additional parasitic elements. On 10 m it works as a 5-element beam - may not have the gain expected by a "true 5 ele beam" - and on 15,20 and 40 m it's a rotatable dipole. Then a Vargarda 6 element for 2 meter and a 5 element for 6 meter. A 88-108 MHz receiving Yagi - 3 element - is fixed in 45 degrees. 

I have a transverter for 1296 MHz - directly mounted under and connected to the FlexaYagi - 2 watt output. IF is 144 MHz to a Yaesu FT-290RII in the shack. Normally I hear the beacon SK4BX - distance 136 km.

Some of the other antennas are - active antenna Standard Radio AA-300, Coaxdipole 135 - 155 MHz, 70 cm yagis etc.

On the roof of my house there are some antennas - A Diamond X-510N and a refurbished 1/2-wave CB-antenna - tuned to 29 MHz!


On the garage - a Diamond CP-6!



And on the roof of the playhouse - a Diamond CP-5!

The CP-5 and 6 has RF-chokes - mounted very close to the feeding points - made of a number of turns of the coax-cable around a 4 inch tube!

Other antennas are: Butternut HF9V, Icom AH-710, Diamond W-8010 and a Cushcraft R8! A vertical 1/4-wave groundmounted antenna for my 30-meter APRS avtivity is connected to my Icom M-710 transciever! The antenna has several radials buried in the grass and very damp soil.


Please send me a message or chat using the above described services and frequencies. I:m quite often active on APRS SM5RVH-7 which is possible to reach in many ways - example: Send me an Aprs message using RobustPacket on 30 meter - very high availability - it's Robust ;-)!
