Low Cost: |
A transmitter that uses this small of a signal is realatively easy to build with easily aquired parts. I have many of these parts laying around my shack, so if the hankering hits me, I can throw one together in an evening. |
Less Power required: |
Since the signal used for transmission is low, conversely the power required to run the station is low. Most QRP rigs can be operated from AA batteries. Although D cells would provide longer QSO's. I operate using a 12 volt lantern battery for portable use and my bench power supply from my shack. |
Transportable: |
For those who like to backpack or camp, one of these rigs could easily be carried to the top of a mountain for extended range. The largest piece could well be the antenna! |
More efficient: |
The key to any good radio transmission is matching the antenna to the transmitter. High-powered rigs, though equally as crucial to match the antenna for mininum power loss, are more forgiving since there are more watts to waste. When a QRP rig has a finely tuned antenna it can often reach distances a higher powered, mismatched transmitter may not. When you are only dealing with .250 to 5 watts it requires much closer attention to antenna construction. |
More rewarding: |
A QSO (I can communicate with_____) from a small battery, or signal, can often give a greater sense of accomplishment. Especially if it's accomplished with a transmitter made with your own hands. Anyone can hit the airwaves with a thousand watt factory rig and make a contact. |
Emergency Preparedness: |
The ability to communicate in a time of emergency is paramount. Being outfitted with a small transportable, low power means such as QRP appeals to me. Especially during these times. |
