[Icom] Seeking better audio from my IC-746

Wed, 4 Dec 2002 16:48:09 -0500

I use an RCA speaker I purchased for about $20.00 from Radio Shack.  It
has a tweeter and woofer and is in a decent enclosure.  It works very
well with my 765.  That rig, by the way, does have a tone control.  I
think a decent auxiliary speaker in that class might well be worth a
look.

I think you might achieve some change in tone by playing with the IF
shift to either emphasize the high or low frequencies.  Of course there
are limits as to how far you can go with that before you begin to have
an adverse impact on signal sensitivity and the signal to noise ratio.

Subject: [Icom] Seeking better audio from my IC-746

I'm wondering if anyone has tried to improve the quality of the audio
from
their 746 by using better external speakers. When I bought mine (back in
2000), I purchased the ICOM external speaker thinking that I would get
better sound than the top cover-mounted speaker in the 746 itself.

Every day I look at that external speaker and think that it is probably
no
better than the one in the 746. The speaker element itself is no more
than
3-4 inches in diameter. I'm not sure what's in the rest of that external
speaker unit (plastic box), but I'm guess it's just air.

I've used headphones with the 746, so I know it is capable of better
audio
than what I'm hearing from the external speaker.

Also, is it just the 746, or do ham transceivers in general not provide
any
tone control?
