Carl said "centered".  Not "fully open".  Do I remember that unlike  
many bandspread arrangements, the HQ-129 is aligned with the  
bandspread capacitor HALF MESHED when the main tuning dial (and  
bandspread dial) is/are set to the appropriate set point?  If so,  
maybe someone has changed the relationship between the bandspread dial  
and the capacitor.

Many radios are set up so the bandspread dial is at its upper  
frequency, the bandspread cap is at it's lowest capacity position, and  
the logging dial is at 100, and the main dial is set at the upper end  
of the section of the band to be spread.  Often this is at the upper  
end of the ham band as it was at the time of design/manufacture.

Worth checking.. don't rely on my (possibly feeble) memory here.

Oddly, a TMC GPR-92 I have here uses frequencies above the ham band  
edges, e.g. 4.1 mc for 80 meters.  Maybe they accounted for MARS use.
