SOTA review

Vor zwei Jahren wurden etliche SOTA-Referenzen in DM (Deutsche Mittelgebirge) gestrichen. Nach der Anzahl der SOTA-Spots ist die Aktivität „gefühlt“ gesunken. Aufschluss gibt die SOTA Datenbank.

Die Aktivität in DM sank somit seit 2008 um 73,8%. Während 2008 139 registrierte DM-Aktivierer mit durchschnittlich 22 Aktivierungen qrv waren,  waren es im Jahr 2010 nur 89 Aktivierer mit durchschnittlich 11 Aktivierungen.

In England (G) stieg die Zahl der Aktivierer, aber die Anzahl der Aktivierungen ist abnehmend  bis konstant. In Wales (GW) fiel die Anzahl der Aktivierungen um etwa 50%, aber die Anzahl der Aktierer stieg von 15 auf 24.

2008 hatten wir insgesamt 10.510 Aktivierungen, 9.796 in 2009 und 2010 einen Rekord mit 11.135 Aktivierungen. Die Zahl der Assoziationen wurde verdoppelt: Von 25 auf 50 (100%). Die Zahl der Aktivierer stieg nur um 23% von 627  auf 810. Die durchschnittliche Anzahl der Aktivierungen pro Aktivierer fiel von 28 auf 11.

Now, 2 years after the lost of  many references in Germany,  is a good time to look and compare about SOTA-activity.

The activity in german Low Mountain Region dropped since 2008  by 73,8%. While 2008 139 DM-registered activators where active with 22 activations average, it were in 2010 only 89 activators with averaged  11 activations (1) .

In England (G) the number of activators raised but the count of activations is constant until decrasing. In Wales (GW) the count of activations fell about 50% but the count of activators raised from 15 to 24.

2008 we had 10510 activations, 9796 in 2009 and 2010 a record of 11135 activations. But the nummber of associations were doubled: From 25 to 50 (100%) but the number of activators raised only by 23%  from 627 to 810. The average number of activations per activator fell from 28 to 11.

DM/NS-108 Piesberg … Activation #63 and #64

I continued operations from DM/NS-108 through November 2010 and continue during December 2010 … but now in snow. Last Saturday, 4th December, it was very cold. We wanted to make a handful QSO only but then a pile up started and after 30 minutes were 40 stations in the log. My first CW activation operating with gloves. ICECOLD! stn: 5w, MP-1, 7MHz only

Yesterday at WNA / SAC my ball pen failed … it was empty. I made only 5 qso, that was the maximum brain-storage yesterday 😉

Summit to Summit

F5LKW/p and DC7CCC/p. I had 5w output into a MP-1 Antenna on 10MHz. Roger (F5LKW) had 10w and a MP-1, too. Here his video:

Marconi VHF Contest 2010 – new ODX from DM/NS-108

DC7CCC operating on 2m
DC7CCC operating on 2m

This weekend was the Marconi Memorial CW Contest on 144 MHz. I wanted to take the chance to work some stations in CW on 2m this morning. I was one hour qrv during a walk over NS-108 Piesberg.  It was my first participation in this contest since I am licensed (1978). I heard a lot of stations but mostly with low signals.  In spite of my qrp station ( 5 wtts / HB9CV) I worked new ODX from DM/NS-108:

  • TM0W in JN36BP 645km
  • OK2M in JN69UN 501km
  • OK1DC in JN69JJ 465km

I heard some stations far far away like OM7W (885 km), but no chance to work them (today).

See all QSOs on the QSO-Map

This is the QSO with OK2M:

2nd SARL RaDAR (Field day) Contest, Sat 6 Nov 2010

RaDAR
RaDAR

(RaDAR = Rapid Deployment Amateur Radio)

This contest is for everyone, at home, in your car, in the field. Any mode , CW , SSB , FM or digital modes. Any band or Satellite. Support your friends in the field, you never know, you may work a really rare grid in the process!

Time: 12:00 UTC – 18:00 UTC

Please see the „Blue book“ , SARL Forum or on www.nwinternet.za.org/zs6bne/RaDAR for contest details. Please use the logbook format available as links on the websites.

The true RaDAR station must have carried the entire station including antennas for at least 1 km prior to setting up, without relying on existing man made infrastructures i.e. antennas, masts or towers.

To be considered as a RaDAR station, the entire station; radios, batteries, mast and antennas must be easily portable and hence the need to carry the equipment for at least 1 km

RaDAR Love

Saturday and Sunday I tried true RaDAR (Radpid Deployment Amateur Radio) activation. That means: Setup the station in 5 minutes or less and use qrp output. Yaesu says, that the internal batteries of the FT-817 produce 2.5w. I used this weekend first time the internal batteries only, the MP-1 antenna, 10m RG-58 and the PalmRadio Keyer. All very easy in the rucksack 😉

For the first activation I decided Saturday morning. That’s the easiest (subjective) time to qualify a summit. I made in 9 minutes 12 QSO. For Sunday I decided the late afternoon. Not the best time for SOTA. I stopped the time:

arrived on the summit until qrv: 4 min 14 sec
qualified the summit (4 QSO made) : 3 min 42 sec
(made 8 QSO in 8 min 1 sec)
from qrt to setdown the station and leave the summit: 3 min 41 sec

the setup could be faster … 😉

Activity Day DARC District Northsea

On Sunday, 10.10.2010, was the DARC District Northsea (I) Activity day. I decided to look into the 28MHz and the 144MHz part. The weather was great, temp. about 16°C and windy. I heard and worked some stations on 10m and called a long period CQ in CW. But no answer. The 144MHz part should start at 1300 local, so I qsyed on 40m where I made a nice s2s QSO with HA4FY/p on Hálás-tetö (HA/KD-042) and another 27 QSO in the following 20 minutes until 1300 local. Meanwhile the summit was full of trippers. When I tuned over 2m I heard a lot of SM6s and OZs with S9 and stronger. But no chance to break the pile up with QRP. I worked some local DLs for the Activity Day and heard >S9 G-Stations. I tuned into the CW band and called „CQ CQ CQ …“. No answer again. But a selfspot on SOTAwatch brought G0BPU with 468km from JO02OB into the log.

After that QSO I wanted to go home and tuned to our local channel 145.450MHz FM. Just wanted to say Tina (XYL), DC1BF, that I will return now. But there were two SM6-stations talking  – with S9++ 😉

The first tuesday in a month: WNA (Westphalia North Activity Evening) and NAC (Nordic Activity Contest) on 144 MHz. After surprising QSOs to Denmark in September I decided to take part in this evening again. Uncommon warm weather for October. 21°C.  As antenna mast I used this evening only a hiking stick … plus my barefoot FT-817ND (5w).

First I worked some „local“ stations within a radius of 100km, only DK5QN in telegrafy. Then I heard a lot of OZs, OZ1ALS had true S9 on the Piesberg and it was easy to work with him. 322km. OZ9KY was not so loud, but for 423km surprising easy QSO. Then I heard S9 / S7 SK7MW. Is it possible to reach this station near Malmö with 5watt and HB9CV? A lot of DLs called him. After some QSO SK7MW returned with „The DELTA CHARLY SEVEN …“ Of course in this moment the signals dropped down to S1. But the operator at SK7MW was very patient. Tack så mycket! The QSO was complete and my QRP VHF ODX from a SOTA summit.

If the wx allows – cu in November 2010.

Welcome Back NS-108

This year the DM/NS-108  got a new „Windpark“ (Power-Turbines) The new turbines are about 150m high. The summit was remeasured and the summit got a new shape. Official height is 196m. Later the summit will get an outlook tower on a height over 200m asl. Since yesterday is NS-108 in the SOTA program returned. That confused some chasers today who looked only on SOTAwatch (This is no longer a valid summit after 31/12/2008) and not into the Database. But I hope we will have some nice QSO in future … today I had to close the operation. Rain started and too much confusion on 40m 😉
