[GreenKeys] OT: remote transceiver

[daveouwerkerk at aol.com]

You can cross couple two BTech Radios like this for a 2M / 70CM Cross Band Repeater using a special RJ-45 Cable:

BTech Radios are not too expensive.

Have a nice day!

That's the most flexible approach I think, but what you really need is a remote base that you can control from other locations on your LAN. The Raspberry Pi-based "Rig Pi" is probably the easiest way to do that, you'd need a Pi of course and while the software is open source, you'd also need some hardware since the Pi doesn't have audio inputs, and some Linux experience to get it all playing together.  Here's the website and you can get a better idea of whether this is for you from the Downloads page.   MFJ sells this as a product called the MFJ-1234.

There have been homebrew solutions offering similar capabilites, this guy's site might be of interest:

The basic idea of streaming audio and sending serial data over an IP connection doesn't sound like rocket science but as always the devil is in the details.  On the other hand, I remember spending weeks building my first remote base controller using actual relay ladder logic, as microcomputers were just coming out and way too expensive for the job in the mid 70s.

Another approach would be to get a 2M-70CM radio that incorporates cross-band repeat capability.   There are some limitations, and online resources that will let you learn more. New radios now have built-in bluetooth for wireless audio, it can't be long before wi-fi remote capability is also standard but I'm not aware of any that are available today.  It will be pretty cool when you can buy a radio, tell it about your LAN, and then run it from anywhere.
