Well, Bill, I didn't do anything as sophisticated as that, although it
would sure be interesting. I no longer have the three Scouts; they just
drifted and jumped too much, and I had too many comments from the
stations I was working. In this day and age of high stability rigs, we
just don't expect that any more.
I am retired and have loads of time to operated. I used my Scouts for up
to six hours at a stretch. I used both the internal and an external
(CMOS II) keyer. My average speed was 25 WPM, although, I did operate
considerably slower, and faster, depending on the other station's speed.
In all cases I had the stability problems, and it did not get better
with length of operation. At least, the comments kept coming, regardless
of how long I operated. I finally set up the last scout I had so that it
sent continuous dits, and listened to it on another rig. The Scout
drifted right out of the bandpass, and I had to retune for it to hear
it. I was using a 500 hz filter in the receiving rig. The other rig was
an FT-1000, and is very stable. I wish I had left it on longer because I
don't know how far it would have drifted, or if it would reverse its
direction. But, I was afraid of causing damage. I treat rigs like
babies...hi.
By the way, I had no trouble at all, with any of the three Scouts on
SSB. I never got compaints of drift or jumping, and I have never worked
a Scout on SSB that gave reason for complaint.I would strongly recommend
that little rig for phone. And, It sure has a quiet receiver. I could
hear weak signals that were down in the noise on some of my other rigs.
A great little transceiver if only they would stabilize it.
