Cheap simple option for private link

Postby radiogaga » 10 Sep 2016, 16:25

Anyone suggest a way for me to set up a private ROIP link?

Looking for something I can run in the car with a 3g connection and another at home..

I have access to several cheap chinese radios and Raspberry Pi's if it can be done that way?

Any suggestions ?

Echolink, just lock it down to allow only your callsign to access it.
I run two links here, 144MHz and 70Mhz but they are both open and work very well.

Thanks - What hardware/interfaces are you using?

I made my own interfaces, much cheaper than off the shelf stuff.
I can send you the schematic if you want to build your own, very easy to build with veroboard, couple of 1:1 line isolation transformers, opto coupler, LED and a few resistors.
I use a cheap USB-RS232 adapter, cost about £2 off ebay or amazon so with a nice box, 9 pin serial socket and all the other parts you can build yourself a decent interface that will last forever - for around £20.

An off the shelf equivalent that will do exactly the same will knock you back nearly £100 (e.g. Signalink, Rigblaster etc), however there are cheaper units floating around on ebay, made by another Radio Amateur for £40.

Let me know if you need any help setting up your link, the only thing to bear in mind is that you will need to scan your licence or send a PDF copy to Echolink for verification which can take around 24 hours.

Yep that would be great if you can send me the schematic please... Can you link a googledrive page or do you want me to PM an email?

Cheers
