I was referring to voice and I'm concerned that many will think a radio
that is -always- limited to 2.1 kHz TX is overly narrow and 'thin' sounding.

Scott,
If you have the KIO2 installed then you must actually have the KPA100
installed in an external EC2 enclosure - if that is true, then yes, the
KPA100 and the KAT100-2 can live together in the external EC2 enclosure.
BUT, if you are trying to fit everything into one K2 package with the

Nope. Not enough room. The K2/100 is quite full. BTW, a K2/100
doesn't need the KIO2 option, it is built into the KPA100.

There's recently been some discussion here about the

Does anyone have this filter and if so, what are your impressions of it? I
need a good audio filter especially when listening to SSB. The pitch of the
noise is fatiguing to me. I don't want to install the internal audio filter
since I will be using this with other rigs.
Thanks,
Gary, N7HTS
Thanks Tom, that's what I was thinking when I adjusted it by ear. I have also
thought about using Spectrogram to get a "visual" of the signal to noise. I
might have it adjusted pretty close because, that's what I was listening for
when I adjusted it. I'll use Spectrogram to look at it when I
Hi Gary:
There's a tuning point, just below the point on L34 where you DO
achieve max. received signal, where the background noise will drop
off faster than the received signal. It's (if I recall) about 1/2 to
1 full turn DOWN from the point of max RX sig.
If you have Spectrogram installed,
