[Icom] Icom Pro II and PW-1 (Do I have a problem here!)

[Bill Tarkington]

George, thanks for the nitpicking cause I have followed you long enough to
know you know your stuff!  Anyway, let me either demonstrate my ignorance
some more or make a point.  Understand the business about determining net
power.  But, in my case, am using a 1500W dummy load rather than an antenna.
So, am I correct in believing that there is no reflected power, and thus no
net, just forward power?

| Actually, the terminology is a little slippery here.
|
| On the transmission line there is energy being conveyed toward the antenna
| via a FORWARD traveling wave.
|
| Similarly, due to the reflection process, there is energy being conveyed
| away from the antenna via a REFLECTED traveling wave.
|
| The NET POWER being delivered to the antenna and being radiated, less
| antenna heat losses, is simply the difference between the Forward and
| Reflected power values.
|
| The Bird is reading either the FORWARD power or the REFLECTED power.
| Subtract those two readings to get the NET POWER delivered to the antenna
| to be radiated.
