Test transmissions update

Yesterday, Saturday March 6, the antenna was erected at Kvarnberget, Vallentuna (northeast of Stockholm). Unfortunately, the exciter for the MW transmitter is not yet ready but it will be in time for another test transmission on MW 1512 kHz from this location. On March 8 a test will be made from the SW site at Sala instead, but with lower power.

The aerial at Kvarnberget is a 37 metre vertical and there is also an extensive ground net at the site. On March 6, the ATU was tuned so that an SWR of 1.1 was achieved. Brief tests with a few miliwatts were then made.

The SW rig on 6060 kHz was supposed to be tested on March 6 but there has been some technical troubles with the transmitter. Hopefully this will be solved soon - we will let you know as soon as we are ready to switch on! With a bit of luck it may be already today Sunday.

Tore Andersson, chairman of the Swedish Ham Radio Association, with the ATU (antenna tuning unit). Tore is in charge of the transmissions on 1512 kHz from Kvarnberget.
