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.
