[ICOM] Icom FL-44A and Inrad #109

[Adam Farson]

Hi Lars,

The Inrad 109 is mechanically and electrically interchangeable with the
FL-44A.  http://www.qth.com/inrad/ The 109 has a -6/-60dB shape factor of
1.6 max., as compared to 1.75 for the FL-44A. 

http://www.qsl.net/icom/filters.html

The FL-109 is the best choice, as its bandwidth is similar to that of the
FL-80 9 MHz filter.

Cheers for now, 73,
Adam VA7OJ/AB4OJ

I was looking for a replacement for the FL44A filter used in Icom
R70/71/751/etc, as this filter seem to be out of production, and stumbled
upon a description on how to install a FL44A at
http://www.mods.dk/view.php?ArticleId=2495. In the text they mention that
"If you do not like FL44A, you may consider using INRAD #109, which will
give you a slightly better shape factor."

Anyone here that knows what difference there are between the FL44A and the
Inrad #109? Or perhaps another of their filters would be better to use as a
replacement for the FL44A?

If one was to order this filter from Inrad, any other filter from them you
recommend for an Icom IC-R71?
