Kenwood usually puts in 3 resistors, 150 ohm & two 33 = ohm resistors in the 500-1600kc receiver input filter. Real easy to find = on the schematic.

I'll build a selective preamplifier for this band soon, to give the = deaf RX what it needs ;-) 73, Wolf DL4YHF ------=_NextPart_000_0595_01C75DA4.8191BC60 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Message
Hi Wolf,
 
I run a TS-930. It has a 9.9kc RIT which seems quite a bit to me = but covers=20 our US band pretty well. Take out the MF attenuator if you have a = schematic=20 handy. Kenwood usually puts in 3 resistors, 150 ohm & two 33 ohm = resistors=20 in the 500-1600kc receiver input filter. Real easy to find on the=20 schematic.

Hello Mike,

Thanks for the info - the trick = works on the=20 TS-690 too, but the RIT range is only +/- 1.1 kHz. So my "sensitive" = RX range=20 ends at 501.1 kHz.  Mal was some 900 Hertz higher .

I'll = build a=20 selective preamplifier for this band soon, to give the deaf RX what it = needs=20 ;-)
