[RFI] 40 Meter RFI Issue

[Larry Benko]

The Cotek S300-112 is quiet.  Cotek and Samlex are the same company or 
divisions of the same company.  I bought the S300 about 5 years ago and 
measured it with a LISN and spectrum analyzer and while I could see 
emissions they were well below FCC part B.  I have never experienced any 
interference while mobile.  The S300 is intended for ambulance use I was 
told.
