At the risk of thoroughly boring you all, I'll summarize the position to
date. I have a good workshop with power tools and I like metal bashing and
am quite happy with PCBs. I even have an electronic calliper so can measure
thickness accurately. However, my eyes will not allow very fine work like
SMD. I am looking to build an SWR meter using two 1 mA meters, one for
forward and one for reverse. I am looking for a practical (non-theoretical)
article on how to build one. I am wondering if there is one the ARRL
handboook before I go to the exp-ense of buying one here in Australia. Most
of the beautifully argued theory on here is way way beyond me. Any pointers
to a suitable article?

One might find that you can BUY a surplus directional coupler for 440MHz
fairly cheaply. Check Ebay, etc.

Then it's just a matter of wiring up electronics to the coupled ports.

:-) I've thought maybe I could just etch one next time I'm making
boards and drop it in the mail to her. Heck, I'd even toss detector
diodes and terminating resistors on it.
