I have the AT-250 external tuner which is supposed to be used with the TS-440S (as well as others), and I have a 8 pin connector cable that came with the tuner.  However, there is not a recepticle on the 440 which matches up with the cable.  There is 1  eight pin socket on the TS440, but it won't take the cable, and the TS440 manual states that this socket it is to be used for a linear amp.   Would appreciate any suggestions for using this external tuner with my transceiver.

To use the AT-250 with the TS-440s, you will have to use it in semi-automtic mode. To do this ...

(1) connect the RF OUT of the 440s to the INPUT jack on the tuner.
(2) connect an antenna to the desired ANTENNA connector on the tuner.
(3) manually select the desired band.
(4) key the transmitter in CW mode.  
(5) press the TUNE button on the AT-250.

The AT-250 cable (for automatic operation) does not work with any rig later than the TS430.

Fully automatic tuner operation on the 440s requires the AT-440 tuner, as described in the 440s' manual on page 15 (para 3.4).

A smoking section in a restaurant makes as much sense as a peeing section in a swimming pool.

Keith:

Are you aware that the FCC database shows your license as cancelled effective 04/16/2010?
