I was trading e-mails with Duncan Brown about this and after hearing my descriptions of the machine's behavior he suggested there might be a short somewhere; that either my terminal unit (an IRL FSK-1000 that I had never actually used) was not working or there was a problem with my cable.  I couldn't think of any reason there could be a short.  I started reading the FSK-1000's manual on the section about the loop jack.  It stated that the connector was a 3-conductor jack with the sleeve being chassis ground.  Then it dawned on me that the connector on the cable I was using, that I built several years ago, was only a 2-conductor cable.  So, that's where the short was.  Duncan suggested that I try the Dovetron TU I have since it has two loop jacks:  one 3-conductor and one 2-conductor.  Once I used used the 2-conductor jack then things started falling into place.  I may have built the cable for the Dovetron but it had been several years since I had used it.

I don't have a permanent Internet connection in the new shack yet but can get a wi-fi extender to pick up the signal from the house weakly.  It drops out often but it was good enough to establish that the machine seems to be working pretty well.  The 60wpm gears are with the machine so I will change those in soon.
