[ICOM] Query.

[D C *Mac* Macdonald]

G'day, Mike.

I believe that  ANY  extended coverage rig
is going to need filters.  If you invited DC to
daylight in, you need to be prepared to have
just that.  The "old" Icom rigs that covered
just the 2 meter ham band were far better
than other rigs of the time for rejecting the
garbage.  This is simply impossible with the
wide coverage of today's rigs, no matter who
builds them.

My opinion, and it's worth what you paid for it!

(;-p)

Mac, K2GKK/5

p.s.  I have been out of computer/Internet
access (willingly) until this afternoon.

p.p.s.  Yes, I use the filters and for about $65,
they  REALLY  work.  You only lose the freqs
between 152 to 154 and 155-157 or thereabouts.
You don't actually lose them, but they are highly
attenuated.  I can still hear local cops, etc. in the
158-159 MHz range, but they are definitely weaker
than without the I.C.E. filters.  There is no noticable
effect on NOAA weather radio stations.

A good enough endorsement, one line - thank you.

But this part sounds like an endorsement for FILTERS.  I am guessing you use
these filters?

Reading into it sorta backwards, it sounds like the 2720 may have serious
problems WITHOUT the filters.  A lot of words about what I might want to add
in order to fix a problem?  Can you tell me - is the 2720 worth considering
without adding filters?  If not, I will continue to shop for a dual-bander.

Thanks - you are the only reply I got all weekend.

Mike.
