If I could ever get enough time to get my shack cleaned up, I would
use mine too. But for the moment it is "stealthily concealed". Yea,
thats it.
The advantage of the two tone generator, is I can't loose it. It
seems that if the same tone is used, it would be fine. But then again
it is not going to work on CW mode. Hrrmph.
Now to plan B. Thanks and 73

The info on the voltmeter can be hard to locate in the manual. In the Rev D
manual it is on page 36 under "Alternate VFO B displays"
