The next item you are going to need is the schematics for the piece of equipment you are going to repair. I have found that schematics are usually available from the manufacturer using the internet. I like to download the schematic and then use it through a program such as adobe reader, so I can view it as a pdf file. I like this program ,because I can make the schematic larger so it is easier to read. It can be found at http://get.adobe.com/reader/ . Just make sure to remove the check mark, so you don`t end up with the free software they may try to give you such as mcafee security scan.

Repairing Your Ham Radio Equipment
There comes a time in every Ham Radio Operators life when some piece of equipment fails. The next decision is whether to send it out for repair or repair it yourself. If you are going to repair it yourself I would recommend that you have some electronic background. You will need to understand what various components are and what they do. There are some websites on the internet to get some electronic training for free. One such place is http://101science.com/Radio.htm they have a lot of information on quite a variety of topics. Another place I have found some interesting videos and lectures is at learner tv http://www.learnerstv.com/Free-Engineering-Video-lectures-ltv024-Page1.htm . There are many more sites on the internet providing lots of information. I would also check out free college courses at places such as MIT http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-002-circuits-and-electronics-spring-2007/video-lectures/ .

I have to say that one of the main reasons I like the shortwave radio is when there is an emergency situation going on somewhere in the world. I have to add that there is an abundance of different makes and models of shortwave radios out on the market with different looks and features. There are some base type shortwave radios out there that are more sophisticated and can be expensive. One that I have seen is the Palstar R30a. That may be my next adventure in the future if the budget allows.
Always remember to keep your antivirus software up to date and running to protect your self from infections.
Thanks for reading and 73s from Dan KC2YTI
