Per the info that Grant K7GT received fron Ten Tec, I've changed R37 in my
Argo-556.

The limit that I can hear the band between code elements is now 50 wpm,
+/- a couple of wpm. The measured value is 2.25k. R37 is mounted on the
board vertically, so I cut the looped-over lead and soldered in a 1.2k
resistor in series with the cut lead on the 1k part. Keying still sounds
good on another receiver.
There are no component markings on the PC board in my radio, but R37 is
just to the front of the diode (also mounted vertically) that is almost
touching the right-front corner of connector 'A'. The front of the radio is
facing forward.
