Yaesu FRG-7 Frequency Range Questions
 

I originally posted this over in rec.radio.shortwave but didn't get any
response - hopefully someone here will be able to help.

My Yaesu FRG-7 happily locks to the 30 and 31 Mhz ranges in the positions to
the left of 29 Mhz on the dial. (All ranges from 0-29 Mhz work just fine)

From a brief test, it appears the receiver is quite capable of tuning from
30-30.99 Mhz. Sensitivity appears to be less than in the plated frequency
range
(presumably some attenuation by preselector and the band pass filter for
band "D") but still quite usable.

So here are my questions,

Is this normal behaviour for an FRG-7, or does it indicate a problem ?

Would the long-term use of this "extra" receiving range have the potential
to cause problems for the receiver ?
