Hmmm, I am using the original SCR274 circuits but not original equipment, so it's not adjustable. I suppose I could put an inductor in series with the DC keying relay coil to cause a slight delay?

  A side note for anyone interested:The procedure in the manual for adjusting the keying relay in the BC 375 and 191 calls for making the antenna changeover contact last. That is a guarantee of chirp. It is a simple matter to adjust that contact to make first and it cures much of the problem.
