 Hello,
I am having two problems with my 940.  I am the original owner and this is
the first time that I have had any problems with it.  The two problems are
as follows, as I know them:
 
1) Antenna Tuner:  Tuner will not tune into a known good dummy load or
antenna below 9.194mhz. Tuner just runs and runs and can't seem to find the
lowest SWR? It tunes and works great from 9.195mhz up to 30mhz.
 
2) Mode: CW, Amps/Watts Out:

                        7.250                  14.50                44
 
                       10.125                 14.50                41
 
                       14.275                14.50                   43
 
                        18.140               14.25                    51
 
                        21.325                 14.50                    34
 
                        24.960                   14.75                 48
 
                        28.500                  15.00                    35
 
                        29.350                  15.00                    33
 
                                            PWR Control at "10"
 
        When I open the "FB" lead from the "AVR" board and verify the
current there and VR6 on the Control board is set to "maximum", I see the
following:
 
                                                Weston or
    940                    940            Fluke 83      Bird 43

    14.275              FM             11.5                     170W
    14.275             FSK            13.0                    190W
    14.275                AM              7.0                    50W
 
                                         PWR Control at "10"
 
The 28v supply tests ok. Any idea's or thoughts on either of these two
problems would greatly be appreciated.
