The following ARDF equipment has been owned and used by Hans Sundgren.
The current 144 MHz receiver failed occasionally by refusing to receive anything. But it worked most of the times. This was not acceptable when travelling abroad for larger ARDF competitions, so Hans ordered the improved version now called 145E. The option "electronic compass" was also fitted.
When running in the forest Hans occassionally stumbles and falls to the ground. When this happens, the antenna elements are sometimes bent. Hans bought extra spares already in 2010, but they have now been destroyed. Hans orders 2 new sets of spare antenna elements. Price: 16 Euro per set of 4 elements.
Just plug it in to the DIN-socket. Actually, this is one benefit with the DIN-socket; it gives access to both audio and battery poles, as well as it is used for the on/off switch.
July 20xx and August 2010
Hans has been running with the Saltsjö Data receiver since 1989. This direct conversion receiver has a low sensitivity resulting in that transmitters are not heard during international championships. Something has to be done and a group of Swedish runners decides to buy the Superfox, a superhetrodyne, before going to the world championships in China (?).
The receiver gets a little unstable after 10 years so Hans buys a second one, to be on the safe side.
After a decade the first reciever still works except for that the side determining function (whip antenna) does not work at all. There is no difference in directions. The receiver is sent to the supplier during the European Championships in Poland for investigation. One week later Hans receivs a nice functioning receiver. "It needed a complete "overhaul" according to the repair engineer. The receiver now has a new DIN-connector and is water sealed besides functioning perfectly. A manual addendum is also included in the package. Cost: 0 SEK.
The receiver is not working and Hans sells it to an ARDF runner in Göteborg who is also an electronics engineer. He manages to get it in operation without problem.
Hans starts to practice radio-orienteering (ARDF) in 1988. First he borrows a receiver but after some time he decides to build his own and buys a kit from Saltsjö Data. After running with the original design of the receiver, he wants to change the physical design to be flush, without protruding knobs.
