[TenTec] omni 6 plus

[Jeffrey Hannon]

hello,
i am new to the omni 6 plus. just got a nice one serial #2A10249. it has cw filters in it ( inrad 400 hz and 250 hz in the 9mhz and 6mhz if).
just put in the inrad 600 hz roofing filter. i have s1-3 and s1-4 in the on position on the roofing filter so that it is activated when N-1 or N-2 on the omni 6 is pressed. anyone have a better way of activating the roofing filter? also does anyone know if this is a late or early production of the omni 6 plus?  s meter seems a bit stingy compared to my icom and kenwood radios any ideas? 

thanks Jeff KC2JDU
