My turn with a question. 
What would be a good (cheap) analog  (or digital ) scope to use for the sole 
purpose of observing my transmitted signal?
And being I have zero experience with a scope, what would be the easiest method 
of hooking it up? Just a simple loop over the coax or... ?
Something that would fit on (or near) the desk with out taking up the entire 
Thanks to all,

  To expound a little further on analog vs digital:

  Analog scopes are fine for a repeating waveform such as RF, or one
  which changes relatively slowly such as an audio frequency voice

  Digital scopes are best for a one-time event which is either too fast
  or too slow for the human eye to capture well.  One example would be
  capturing a relay or switch contact bounce.  They also (usually) have
  the ability to store and print out individual traces.

  Each has their place, but for amateur radio purposes, an analog type
  is probably adequate, as well as easier to fix and cheaper to buy.
