Today we had some time for getting a look inside the stack match box by WX0B – Array Solutions.
Although we will not use it for stacking purposes (since we do not have high enough towers) it will help us during the multi direction propagation opennings between Europe and North America.
Multi direction switching is very desirable in huge pileups, when propagation seems to open in two or more directions. Switching to a specific direction, improves the gain to that direction AND attenuating signals from all other directions – that improves a lot the capacity of the operator to pick up the signals in a very noisy envoirment meaning higher QSO rates.
During the tests, the unit worked properly and all the contacts seemed in pretty good electrical conditions nevertheless the overall signs of the years up on the tower.
