Re: Alignment meter
As well as an output level meter (in my case a simple, venerable but very flexible in terms of range and loading Dymar unit), I like to hang a 'scope in parallel with it. Then, I can watch the demodulated tone rise out of the noise when using the necessarily low RF input level (as discussed above) and be certain that I'm not peaking noise, sprog or instability. Of course, one could simply listen to the output instead but I find that long periods of straining to hear low-level 400Hz peaking and subsiding with a complex receiver can get a tad brain-numbing.
