A Different Construction Approach
Society
There are a few kits available for the skilled builder.
These include Down East Microwave and DB6NT.
The kits are not builder friendly such as a Heathkit
with thru-hole components and point to point wiring.
These kits require precision assembly using surface
mount construction.
The following approach uses modular assembly
techniques with minimal surface mount assembly.
