Having problems accessing or using repeaters on 2m? This article may help.

Do you want to try your hand at Radio Direction Finding (RDF) or 'Foxhunting' ? Then try this easy to build  & repeatable antenna design.

A design for a simple and repeatable 4m antenna.

How to  modify a Kenwood TH215 to operate on 12.5KHz spacing. In particular the key piece of information missing from all the other articles I found on the Web !

Some claim that larger diameter “choke baluns” are less effective than their smaller diameter counterparts, even when the turns count is reduced to maintain equal inductances in both designs.  It has been claimed this is due to “stray capacitance” in the larger diameter coils.

This analysis casts doubt on that claim by asking “ Where is the stray capacitance formed?”
 

Some  amateurs claim they  can  'measure'  how much  power a  remote  station is running by  using their  S  Meter.

This note shows why this claim is flawed, even when the S Meter is used to compare the remote station against another station running known power.
