Hi George,

Interesting! This is the only complaint about hash. I'm wondering want is 
different in your setup or if you have a more critical ear ?  
Please describe your antenna, ground and the proximity of the K2 to the 
MFJ-4125. 
Any special circumstances under which the hash can be heard or not ?
Are you recommending the Alinco DM-330MVT over the MFJ-4125 ? Do you prefer a 
linear PS over the switching PS ?

Thanks & 73,
Jim WA2UMP K2:2679
