10 km Long Range Transmitter Circuit 2 meter band
The post explains a 10 km long range transmitter circuit using ordinary components .PCB fabrication also explained. With the increased activity on 2 metres, some who may have contemplated working this band, have possibly been deterred by the cost of a " black box " and the uncertainty of modifying commercial equipment. With this situation in mind, the Author has , designed a simple , easily-built 2m f.m. transmitter, that can be assembled by anyone who can use a soldering iron and small tools whilst possessing a reasonable amount of patience. The completed unit will perform well, being as versatile as the constructor ultimately wishes to make it. An r.f. output of around 1 watts can be expected if the unit is constructed as described but power far in excess of this may be, achieved if the design is regarded as a working basis and the p.a. stage is developed. Construction Procedures for the proposed long range transmitter circuit A simple printed circuit technique is employed...
