About us
The 5P5T group consists at present of OZ1FDH, OZ1DJJ/OX3LX, OZ1GER, PA5DD/OZ1DOQ and OZ5BD/OX5T. We have participated in VHF contests for a number of years and back in the 80'es and 90'es the members were active with the callsigns OZ5UKW and OZ1DOQ/P. Then after more than a decade of doing other things (like raising kids and getting a job) we started again with our old passion for VHF contesting.

We are active on 144 MHz every year the first weekend of sepember from the island of Moen (JO64gx). The QTH is Kongsbjerg 134 m ASL at the southern part of the limestone cliff formation on Moen. Access to the site is through small and slippery trails in the forest, but it is a wonderful and scenic site.The take off from Kongsbjerg is almost perfect with a negative horison 360 deg. Another advantage is that the nearest QRO station (SK7MW) is more than 50 km away.


Contest site on Kongsbjerg in 2011. The operator room is in a horse trailer (we left the horse back home) and the PA's are in a separate trailer in order to keep the blower noise levels down

We started with the callsign 5P5T in the 2007 Region 1 VHF test and have been active every year since then. QSL responsible is OZ1FDH, we normally send out QSL for all contacts once a year in the fall. In 2011 we broke the old OZ5TE points record from 1981.The final results from DARC gave us a 2nd place in the multioperator section. 2013 was an even better year. For the first time since 1972 an OZ station has won the region 1 VHF contest! You can find more info by searching for 5P5T on the web or YOUTUBE.

Antennas are everything for a good contest. During the years we have experimented with different setups. The main antenna systems are 8x3 el and 4x10 el vertically stacked. All the antennas we use are DK7ZB designs from NUXCOM. These antennas really made a difference for us. By their UFB performance and good value for money, they are truly contest winners. In 2013 we used 4 antenna systems on which we transmit and receive simoultaneoulsy, for receive each system can be used individually.

The station is an ICOM 7700 + a DB6NT transverter and for the 2nd operator RX we use an ICOM 756 Pro II. In general we use simplicity as the guiding principle for our station setup. The more simple the operator interface, the more the oprator can focus on the QSO's. The logging software has so far been Taclog developed by OZ2M. This software has the most simple and best user interface of all logging programs we have tested, unfortunately it is no longer compatible with the recent windows systems and we probably need to change to a more modern but also less user friendly logging software. Alternatively we may rewrite Taclog for windows, -stay tuned for more info on this.

An often forgotten part of the portable equipment is the mains supply. We are fortunate to have access to a 30 kw diesel generator, which delivers 240 V of pure sinus AC and keeps all the equipment in good health.

For decades it has been custom on the HF bands always to give a standard 59 report regardless what strength of the signal. Unfortunately this tendency has now also spread to VHF. Most contest programs simply has 59 as a standard report. But especially for VHF and UHF there is a lot of value in a correct signal report to help you accomplish a QSO. If you send out a 51 report you tell the other station that the signal is weak and they have to make an extra effort to get the contest exchange to you.
Often we have experienced that we actually receive e.g. a 55 report, but as the contest program put in 59 as a standard report, the QSO is not logged correctly. That is a silly way for everybody to waste points and QSO's. Therefore we highly reccomend that everybody stop using automatic 59 reports, instead use a correct signal report to improve the number of succesful QSO's for everybody. Likewize automatic 59 reports in contest log programs should automatically disqualify a logprogram for the serious contester.
