Below are examples of some of the Allstar Nodes I have recently built, I run each one 24/7 for some three weeks. Then if all is well I post the design here. They do not get on this page unless they are easy to construct, work reliably and above all have good sound quality.
Simple Node, DMK URI Design.
Simple Node, ARA-1 Design
Classic CM108 Mini Node.
Motorola GM340 Node.
Radioless Node.
The Headset Node
I have been asked about this few times, but the fact is that I do not sell Allstar nodes, I just do this for my own amusement. However, I am of the opinion that putting one together yourself is well within the capabilities of almost all radio amateurs.
