To switch all the available antennas for the two HF stations Thomas PA1M and I have designed and build a new antenna switch system. All the switches are steered by MicroHAM software and hardware.
All the switches are home made by several designs. Last part off the new system is to build 6 high p[owner bandpass filters and buy 3 triplexers.
Also I have to finish the cables and make it more correctly.

Switching system

In this part the four radio have their coax entry.

In this part are the switch for each band.

Here are the U links from MicroHAM witch wil swicht all the realys in the switch as also the other parts outside like stack switches relays for tuners etc.
