[TenTec] Orion v2.059d - cw rise time measurements

["Bob Cunnings" <bob.cunnings@gmail.com>]

I wanted to see if v2.059d improved the accuracy of the cw rise/fall
time setting, so I took a scope home this weekend and looked:

Rise time results in ms, average of 5 measurements:

Indicated                   Measured

3                              2.1
4                              2.7
5                              3.4
6                              4.0
7                              4.7
8                              5.3
9                              6.0
10                            6.6

Generated dits with internal keyer into a Bird Termaline load at 7.035
MHz. Sampled  with 7:1 resistive divider (3500 ohm total) across load,
measured with Tek TDS210 with sweep of 500us/div or 1ms/div, depending
on setting. Vertical scale at 1V/div and output power adjusted to fill
screen, power setting was "42". Tried to be careful with placement of
cursor for measurement, but numbers probably no better than +/- 0.2
ms.
