Once again, fantastic Istra Contest Conference event, great to meet a lot of friends there. Thank you to the organisers for letting us show what's new, and thank you to Nocturn Devices for joining our hobby too. We are looking forward to working on future mutual products with them.

Manufacturing insights: relay test

Before installation in the antenna switch, each relay is individually tested for contact resistance and insulation. The insulation between the contacts is tested at 1KV, contact resistance at 1A, and 10uA currents. About 2% of brand-new relays do not meet our strict requirements and are removed from the process. Perfection is in the details...

NEW PRODUCT: TRIO

The TRIO is a remotely controlled, high power, high isolation, single radio antenna switch/controller combo operating up to 70MHz. Modern, simple to setup, intuitive to use.

The TRIO connects up to three (3) transceivers allowing to share common power amplifier or antenna tuner between transceivers, feeding up to six (6) RX/TX antennas, and selecting one of up to three (3) RX only antennas including a switchable bypass for a pre-amplifier or attenuator. All of this without rewiring any cable.

In addition to six (6) RX/TX antennas and three (3) RX antennas, TRIO supports up to four (4) optional ARXC.REL boxes connected to TRIO via RS-485 using CAT5 cable over distances up to 1500 m or up to 5000 m using optional ARXC.LoRa modules. Each ARXC.REL box provides four (4) individual SPDT contacts, controlled by the user selectable template to control all types of external antenna switches including antenna arrays. For each ARXC.REL box, TRIO provides separate control and real-time status on the front panel in parallel with the web user interface.

NEW PRODUCT *** ARXC.WIND ***
https://www.microham.com/contents/en-us/p370.html

Our ARXC.WIND module interfaces external wind sensor, automatically collects wind speed and direction data and adjusts the antenna’s position connected to the ARCO. In high-wind conditions, the system ensures that the antenna is “parked” in a proper alignment to the wind. By optimizing the antenna's orientation, the ARXC WIND reduces the forces acting on the antenna during storms or high gusts, preventing potential damage, even in the absence of personnel at the station.

Chilly weather here, but the ARXC WIND sensor installation is ready for final pre-production testing.
