I would love to use my K3 on AM WIDER than 6 KHz (+/- 3 KHz).
If I were to buy a wider filter, Maybe 8 or 9 KHz and install it
will the K3 Firmware accept it ?
Thanks Ray WA6VAB

The K3 now accepts the FM filter (13 KHz) for AM transmit. However,
the DSP still generates 6KHz (+/- 3 KHz give or take) wide AM. That
is not going to change without programming by Lyle.

After installing the 6.0 kHz AM filter I notice the Max DSP b/w is 5.0 and the
Shift center is 1.5 kHz.
Is this the normal set up?

If you press and hold the SHIFT control (see NORM on VFO A), it will
reset the Fc and BW to what's normal for that mode.

Nor is 3 khz and 1.5 kHz center.
My main question is is it normal for the BW to max out at 5.0?
Probably doesn't matter since there is no audible difference as you advance
wider than 3.2 anyway.

Hi Rick,
Yes, that's normal. The displayed bandwidth is audio bandwidth.
Remember that AM uses both sidebands, so the 6 kHz filter passes 3 kHz
above and 3 kHz below the carrier (6 kHz total). Your resulting audio
bandwidth will actually be somewhere around 3 kHz.
You can get more audio
3.0 / 1.5 *seems* right. If the BW control goes up to 5.0, I think it
tops out at 3.something.
There is something about this that was on the list, last year, but I
can't find it in the huge stack that develops...

Thanks Matt,
I'll chalk it up to Normal.

Those readings are normal. An indicated 3 khz bandwidth requires the 6 khz
filter - 3 khz on each side of the carrier. Since AM is DSB, one has to
double the indicated bandwidth to see what filter is needed.
