      Paul, Remember that the carrier is suppressed in SSB mode. When you just key down, no power is being transmitted until something comes from the microphone.

        Remember that the carrier is suppressed in SSB mode.  When you just key down, no power is being transmitted until something comes from the microphone.  You either have to talk, whistle or hold a practice key to the mike to see anything on the meter.  That is why it is best to do calibrations using either FM or CW.  The SWR reading will be the same for any mode.  The directions for my 735 state to check the SWR using FM.  I have found the CW is quicker and easier. 
         
        Note:  There are restrictions for the use of FM on some bands, for instance, Techs cannot use FM on 10 meters.  No FM is allowed on 60 meters, nor 30 meters, nor is it allowed in the lower portions of most HF bands.  Consult a band chart before you transmit FM on any frequency.

          Hi Paul..
           
                  Joe is on the right track here.  It would be difficult to obtain a meaningful result when the power levels are jumping all over the place.  It may be that your rig has the SWR function disabled when in the SSB mode.  Have you tried it in the CW mode?

          FM with no modulation applied is a steady carrier.. Make and break it appropriately and you have CW. Old satellite trick used years ago when you didn t have

            FM with no modulation applied is a steady carrier.. Make and break it appropriately and you have CW.   Old satellite trick used years ago when you didn't have an all mode rig to work the birds on CW.  Turn the mod pot to zero, put a key in place of the PTT switch and voila !!  CW.  Also a way to build a nifty beacon transmitter.
