RX BPF

RX BPF based on OH2U filter design with slightly modified values to increase the bandwidth. PCB design made by SM2WMV.

VHP stackbox 20M

Stackbox made with russian vacuum relays, designed to switch the angle of radiation of the future 6/6/6el monoband stack for 20M.

VHP stackbox 40M

Stackbox made with russian vacuum relays, designed to switch the 3/3el stack for 40M to change between having both beams in phase or the beams out of phase, hence controlling the vertical lobe.

Injuries

Showed a saw blade into my foot...stupid thing to do. Before I took the pictures I had removed most the puddles of blood though, looked a lot worse before that.

Granger amp box

A box which is used to control the granger amplifier in the basement. This way there is no need to run down when the amplifier trips, when needing to change band etc. The box can also be remote controlled via an USB interface.
