Hi Tom,
I've had some strange behavior with N1MM from time-to-time. It would
take a long time to update the frequency and if I were S&P and worked a
station it would wipe out the qso because, I think, the frequency would
suddenly catch up and N1MM thought I had qsy so it wiped the qso. This

13 kHz comes quite close to the 15 kHz DSP IF, so using the 13 kHz

In the past week I've been tuning and pruning an inverted V dipole I've put

significant differences between SWR readings on my K3 and an external

I understand the demodulation theory just fine but the concept of having the
DSP act as an audio filter instead of an IF filter causes some confusion
since we've been hyping up "IF-DSP" filtering for several years now and
suddenly we talk about AF-DSP in only one mode, AM.

The communication between N1MM and the K3 is not one way. N1MM is also
polling the K3 to see what the actual frequency is, which means your
baud rate setting is probably having some influence as well. I'm using
a fast (quad core 2.4 GHz) computer and a 38,400 baud rate, and the

Steve,
The DSP audio bandwidth *can* be moved out to 5 kHz for AM - that is
true, and it does not depend on the filter you have installed.
With the 6kHz filter at the IF, the bandwidth is constrained by the 6
kHz roofing filter, so the realizable audio that can be demodulated is 3
kHz - it make

This doesn't quiet make sense to me. I have the 6khz filter in my K3. The BW
indicated on the K3 is 5Khz. If I add the 12 KHZ filter and the K3 still
says 5KHZ and that 5KHZ is the "audio" bandwidth, what good have I done?
Most any old SW receiver sounds a bit muffled at only 6khz bandwidth.
Excellent. 73 and enjoy Gregg!

Bill,
The 5 kHz width indicated for AM is the *audio* bandwidth, not the IF.
The IF bandwidth must be more than 2 times the audio bandwidth for an AM

Remember that the 6 kHz filter must be used for AM transmit.
