[Kenwood] TS950 Transmit Spurs

Tue, 27 Apr 2004 09:14:51 -0400

I've never heard of any such problem with my TS-950SDX, Ed. I have another
active DX'er and contester less than a 1/2 mile from me and he always has
told me that he can operate within 1-2 KHz. of my signal without any
problems and vic-versa. We both use the SDX models set at 4ms. keying timing
and 270/250hz. CW narrow filter combos in the 3rd. and 4th IF's.
