[Motorola] Motorola Astro Spectra

Hello group, 



I have the possibility of picking up some Spectra's (110w, trunk mount).  I noticed some have "1Meg" and "2.5 Khz" on the ID tag and some don't.  What is meant by 1 meg, and does the 2.5 Khz mean they are capable of narrow band?  Some of the Astro Spectras have neither the 1 Meg or 2.5 Khz on the ID tag.  What's the difference?  Is one type more desirable than the other?  Thank you for any information. 



Regards,
