LA2NI's OpenHPSDR I/O Board (Kicad Version)

OpenHPSDR P.A. OpenHPSDR Input/Output board by LA2NI (Munin 400)

This picture shows an early design of the I/O board by LA2NI

This I/O board is part of a set consisting of a 400 W LDMos based RF power amplifier (Munin 400), a medium power (600 or 1500 W) Zolotarev low pass filter, an Automatic Antenna Tuner (ATU) nickname « Aries » and a 4 port antenna switch.
