[TenTec] Argosy and Delta on CW with 422 keyer

[Frank J. Krozel]

Just doing a little research on the Argosy and the Delta..
Some fellow on the internet stated that he had a problem with keyers and mentioned MFJ...
As that is probably the only mode I will use with them... I am curious if there is an issue with external keyers.  I don't recall using my MFJ422 with any of the somewhat modern radios I have had.
Thoughts?
