Hi Mark,

When did you buy your set? I got mine last year; I did have the factory
replace the 2.2 kHz SSB filter with their 2.4 kHz (nominal - measures
2.2) crystal filter (and what a performer THAT is!) - I also had the
daughter board fitted - but I find the other filters to be first-rate.
I had the 6.5 kHz filter (from the basic 7030) added in also, so I have
5 filters, which is all I personally need. But I have found that the
audio is superb with the 5.5 kHz ceramic filter, the one I use most of
the time with sync on, and, of course, using the crystal filter when
ECSS reception is desired or when listening to sideband, I find the
sound is as good as regular AM. I do not know the skirt measurements
for my particular unit, but I rarely hear interference that I can't get
rid of and I almost never hear heterodynes.

But you're right - if the stock filters don't satisfy you, it is VERY
easy to replace them with ones you prefer.

That's just another nice feature of this radio.

Best,

Joe


I've had my radio for about 3 years, and I bought it second hand.

The filters I use are crystal ones made by filtronetics for the Racal
6790/gm. I created a shelf on the inside of the back panel with some
angle aluminum and flat stock to hold them, and they're wired in with
RG-174.

The one marked 3.24khz reads 2.9 and has a shape factor of 1:1.33 and the
one marked 6.8 reads 6.1 I don't know what it's shape factor is, but I'm
sure it's steep. I experimented with a few other filters before deciding
on the 6.8

With those filters the sound is very close to what I get from my Harris
RF-550.

Regards,

Mark
