Finished the dipole for my 4El DK7ZB Yagi for 28MHz.
Hope i get the rest finished until Jan. 8th ;)
28MHz Dipole
Habemus Dipolum
DVRPTR, DVModem and D-Star
Last weeks from time to time i am playing around with the really nice software DV-RPTR Control Center from Kurt, DJ0ABR.
I am using a Siemens C5 modified for 70cm and equipped with a DVModem for digital voice or a DVRPTR PCB with a external TRX (either FT-857D or another C5).
The hardware is connected to the PC via USB and the DV-RPTR Control Center software connects it to XReflectors, Reflectors or Repeaters. It can also do callsign routing.
A really nice addon is the display of some slow data that is transmitted in parallel to the voice stream. There you can usually see the name or QTH of your QSO partner. The location that is displayed by the PC software comes either from GPS (DGPS) data transmitted by the sender or from a static lookup of hamqth.com.

For Sale / Verkaufe
In the future i will put some equipment that i do not use anymore to the “For Sale” page. Most of the stuff is a bit special probably but if you are interested please contact me via eMail (dh5ym@darc.de).
In Zukunft werde ich ab und an ungenutztes Equipment auf meiner “For Sale” Seite eintragen. Die meisten Sachen sind wohl etwas speziell, aber bei Interesse bitte ich um eine eMail an dh5ym@darc.de.

CQ WW DX CW November 2011
Some impressions from the 2011 CQ WW DX contest in CW. I did only make a few qso but the screenshots are impressive.
CW WW DX CW 10m - 1430UTC, Nov 26th 2011
CQ WW DX CW 20m (Sunday)
CQ WW DX CW 40m (Sunday evening)
CQ WW DX CW 80m (Sunday)
CQ WW DX CW 160m (Sunday)
As antenna i used my portable 10m vertical wire. Receiver was the N2ADR/HiQSDR frontend.
D-Star / Digital Voice activities
This week i got the new DVRPTR pcb. (see www.dvrptr.de)
Connected to a Windows or Linux PC it is easy to create a hotspot for connecting to D-Star Reflectors ans X-Reflectors. From time to time i am running a hotspot on 430.225MHz from my home location in the east of Dresden (Just when i am at home). Probably someone can hear it. It is usually connected to XRF010B.
10/24GHz feedhorn by W1GHZ
From Paul, W1GHZ i got a dual band feedhorn for offset dishes for the 10GHz and 24GHz band. It was somehow funny to explain the customs officer what it is ;) Now it is my turn to complete the station and get on air. I am excited.

DUR October 2011
Last weekend another DUR activity from Triebenberg JO61XA. This time 23cm only. I did not modify anything in my setup.
The conditions were better than usually but degraded during the 3 hours. I was able to work OZ3ZW, HA8MV/p and also DL7QY just to name the 3 most far stations out of 22 QSO.
In the end this was a new record for me from JO61XA with a sum of more than 3000km.
The other side of the medal: usually the far stations are just workable after a ping in KST chat. Fortunately i could work OK2UYZ and DH7OT random this time. On the other hand this activity contest should gain some activity on the bands and this it achieves with and without chat.
I think now i need to improve my station again now. Probably some more power on 23cm. 10GHz and 24GHz are in the pipe but it depends on my spare time when i will complete them. At least W1GHZ promised to send me one of his nice dual-band feedhorns.
new laser ODX, 43km
During UHF/SHF Contest from JO60LK i had a new contact with DK5WMA in JO60MT.
The new distance is around 43km and a new ODX for me. The signals were really strong this time and it paid out to move
the RX PCB and the detector to metal boxes. No radio demodulation anymore and ufb AM QSO,
Later on it worked also with DO1CTL and during the night with DH0LS.
The picture shows my laser station and the green point from DK5WMA in the middle of the foto.

September DUR
Last weekend i had another try in the DUR activity. I was qrv on 23cm only. The result was quite good. First time i was able to work HA8MV/P with my 15watts. When bringing down the antenna i faced strong rain.
Before the contest i fixed the RX part of my transverter and i made the voice keyer system as well as the headset connection working. Now operation is much more comfortable.

ST0R pileup
really funny to see on the SDR screen.. 40m CW pileup for ST0R (south sudan) ;)
