There's been a lot of discussion recently about what happens to
multiple closely spaced signals with AGC turned on. We have a new
field-test firmware revision available that offers a significant
improvement in such situations by reducing the IMD caused by
conventional AGC. If you'd like to try

Wayne,
I just received #2724 yesterday and am still inventorying
We now have plenty of volunteers to try this experimental AGC firmware.
Thanks!

To those of you who are testing this: Remember that AGC HLD only
affects slow AGC (AGC-S). So, once you have a long AGC HLD time set up
(0.3 to 1 sec, let's say), you can go back and forth between fast AGC
(with no hold), and slow AGC (with a long hold) just by tapping the AGC
switch.
, the engineers understand the effect and offer test
software for it.
Kudos!
