Beverage switch

For the CQ WW 160m CW contest and the Dutch PACC contest I developed and build (together with PA3FAL) a switchbox which is used to route all beverages to the RX input of the low band stations (40/80/160).

The system is designed to handle 8 receive antennes and route the signals to max 6 radios (2 radios per band). Every station has a remote control box to select one of the RX antennes. Softrock receivers can be stacked onto the mainboard of the PCB which are connected to a Delta 1010LT ADC.

High Power LPFs

Based on the W3NQN designs I build 5 low pass filters. These filters were build to be used with legal limit output power.
