Thanks to everyone who responded, including a couple who scanned and sent
me the Drake nomogram. Unfortunately, I don't believe it does the job I'm
looking for. As I understand the nomogram, forward and reflected power are
read separately, and laying a straightedge across then gives SWR. However,
in my case, I have a power reading that *combines* forward and reflected
power, and a separate digital display giving the SWR. So what I'm trying
to do is to back out the forward component of the forward + reflected
total. A nomogram for this purpose would have total power, SWR and forward
power scales, not forward, SWR and reflected scales as Drake's does.
