Steve,

Regarding the Heath Cantenna....I have been scratching around with power out
readings recently and after a search of the archives for the word "cantenna"
yeilded some intersting results.
What I thought over all these years (since 1964) a 50 ohm load was actually
a
68 ohm load after many years in oil and many heating cycles.
Thought that topic would be timely again here on the reflector.

Don:

"Thanks very much. Yes, the ARRL setup is serious overkill. However, I have 
a Tek 465, and I thought it would be kind of nifty to try to set it up to 
look at my keyed waveform.

As for the matter of running a 50 Ohm source into a high Z scope input, Tek 
has a slick solution.......

It had occurred to me that a cheaper strategy would be to run the rig into 
my Heath Cantenna (remember those?)"
