Hi Les

I also own a Icom R75 but I added some extra filters to it. I added a pair
of 2.8's {FL-96 and FL-103} so they would match up instead of the one more
expensive 3.3 FL-257.

I got the 2.8's for ECSS and for the cheaper price plus I read from people
who bought both the 2.8 and 3.3 told me the 3.3 was just too wide and let
too much carrier noise thru. Also, they said you couldn't really tell that
big of a difference between the 2.8 and the 3.3 for the money.

So, with what I have now, do you think I would really benefit from the added
Kiwa 3.7/3.8 filter? I listen to everything actually. BCB programs, Hams,
and SW broadcasts if I can get them in good.

Do you think I should get the Kiwa filter added? I'm pretty content with
what I have now but who knows what I might be missing out on?

You are well experienced with the R75 and would appreciate your pro opinion
on this matter.

Thank you
Glenn

Just curious if anyone here has had the Kiwa mods for the Icom R75,
particularly the sync and filter upgrades. If so, what was the turnover
time, and which modifications do you feel are the most significant for
dxing?

I've owned a stock IC-R75 and one with "ALL" the Kiwa modifications. In
it's stock form, the synchronous detector is non-functional and the agc
on am stinks. If all you do is listen to utilities, it is ok in its
stock form.

But, if you listen to shortwave broadcast stations and or medium wave,
get the kiwa mods. The Kiwa 3.7/3.8 filter is great for dx'ing and the
sync mod works very well. Add a good external speaker such as the Radio
Shack Minimus 7 and you have an excellent receiver. The Icom dc power
supply runs warm and provides way too much voltage too. Might want to
use a "Real" 12 volt dc supply.

YMMV

The dual 2.8 filters are the way to go if you tune using ECSS, I
absolutely abhore using ECSS for sw broadcast listening, and that is my
reason for using the Kiwa filter module. Of course, if I am looking for
a heterodyne out of Pitcairn Island, I'll use USB or LSB and the narrow
filters. YMMV, I use a Sherwood SE-3 MKIII and a Kiwa Map as I hate
pinched audio. Of course, if I am just listening to a in the clear SW
Broadcast station, I use the venerable RCA CR-88A and a big 10"
speaker, absolutely spectaclar audio! If you use ECSS most of the time,
don't bother, as in its stock form, the R75 is fine for that. Where it
suffers is the non-functioning sync detector and the agc on am
compounds that.
