Re: Send 5 Volts on off signal for ant switch relays

Dave - thanks for those nice words about the FreqEZ Band Decoder.

Simon - my FreqEZ Band Decoder software is free. The Console runs on Windows, and the Controller runs on a Raspberry Pi. You can build your own Controller hardware (instructions provided) or purchase a companion HAT board from me. FreqEZ v1.x (now) supports 16 outputs; v2 (soon) will support 64. More details and a video link on the website

FreqEZ was written with Dave AA6YQ's help and is specifically intended for DXLab users (like me). It can be used as a simple manual switch using mouse clicks. But if you use Commander's >Config >NetSvc settings to send <RadioInfo> packets to FreqEZ's Console - it's automagic. Connect via ethernet or WiFi. No messy serial or parallel ports required.

Hi Dave w6de

Thanks for pointer. Yes, the radio info message has every basic thing needed and solve the laptop issue

There is a Hardware & Software solution for your problem. FreqEz is a raspberry Pi hat and software set that reads the UDP data from DXLab Commander or N1MM contesting software and sends the frequency data FreqEx on the Windows computer and according to a matrix you set up sends antenna selection data to the raspberry pi and a switching board for antenna selection.  Do a WEB search for FreqEZ.  FreqEz was developed by Larry K8UT who also frequents this forum.

Planning for a home brew relay box to route the rig to diffetent ant depends on band.


Can the software send 5 Volts on off signal via a hardware box? Of course, it can be manual control if above not possible.
