[PPRAANet] Temperature Cycling breaks Rigs

All,

 

  I noticed the first winter I had my license and a mobile rig that the display on my Yaesu FT-7900 was dim and slow to respond when it was cold.  I soon began to remove the faceplate from its remote location on the dash and bring it inside when it was cold.  Noticed that it didn't like it in the heat either.  Now, I remove the faceplates from the FT-7900 and the FT-857 when it's going to be below about 25 degrees or above about 80 degrees.  They're both on the table beside me right now!  My vehicle doesn't get much warmer than outside air temp so it must get pretty hot before they come inside.

  Is the main body of the radio able to withstand the cold better than the faceplate, or should it be taken inside as well?  I know the displays react badly to the high and low temps, but is the body more able to take it?  It's just a pain to remove and put back twice a day.

  Any ideas one way or the other?

 

  Why does the vehicle AM/FM radio survive and my amateur radios may not?

 

Thanks.....
