[ICOM] Query.

[Dr. Howard S. White]

Depends on where you live and how much intermod exists where you drive....

If you live in the country then you don't need filters and for most highway
driving you don't need filter...

if you live in a big city and drive near pager towers .. filters sure help
solve all intermod the problems....if there are any....

I have 2 of IC-2720H... work great almost all the time... except right near
(200')  a couple of pager towers on my way home... but my IC-706 has the
same problems with the towers..

I put a DCI-144/440 filter on and all 3 rigs work right under the towers...
