Looking for an ADX Plus have trawled Ebay and the internet but no results not surprising as they have not been used for many years.
I threw one in the bin last summer as I could see no possible use for it!
I have bought a SUP-2400 from the states but until I get my eyes fixed I cant see the smd's clearly even with a magnifier so an ADX plus seems the easy way out.
Am receiving narrow band signals fine on my Nesdr smart.
Any help greatfully received.
