One of the things that can be confusing is a very busy display. I think all
that should be highlighted on the panadaptor display is the DSB bandwidth. That
is what bandwidth you are receiving, not the crystal filter bandwidth.

I would say that's confined to a few and they are probably mostly US firms.

The K144XV module's RX architecture is almost identical to the external

optimized dynamic range (such as with antenna mounted pre-amps etc.)

We can certainly support this, since you can directly enter any
frequency on the current K3 to 1 Hz.
I'll check and see if we have this already in the f/w for fast channel
tuning. If not, we'll have to add it. (We'll need 2.5, 5, 6.25, 10,

Just to extend the idea a little more - Monitor the transceiver output
with an additional option for monitoring the amplifier output also. It
is then easy to see amplifier linearity using a trapezoid waveform.

This capability is already in place. You need to proceed the name of the
memory with a * and they need to be in sequential memory locations in order
to pull it off but once you recall one you can then tune through the
memories with the VFO A knob. This is especially handy for the channelized
