We know that there is roll-off at the top and bottom of the passband,
and we do intend to charaterise this and build a pre-emphasis system, however
we will shortly be changing the equipment, and so it is better to wait until
after the change.

In the meantime, I could move both Rx and Tx a 100 Hz or so LF if that would help.

Problem is I'm using the MB7LF relay for seeing what happens and
it doesn't relay sigs below 136 very well (pace Derek!).
The wobbly osc should be cured soon (why does an osc wobble when
it's got three buffers between it and the load?)

When are you going to come on and work all of us Walter?

When my Morse receive abilities are good enough to follow
25 wpm! I haven't used Morse for 30 years.
