Hello Jim!
Will the new K3 be able to TX on the Alaska emergency frequency of
5167.5 kHz? This is close to the 60 meter band, but not a "ham band"
frequency. This channel is authorized to hams in or near Alaska for use
during emergencies, and contacts between hams and non-hams (for
example, the police or a commercial HF user) are authorized when the
situation calls for it. The authorization is for SSB (USB) only, 150
watts max output.
This should be possible, I'll leave it to Wayne for the definitive
answer since I haven't swept the 60m bandpass filter. With the KBPF3 I
should think it would be no problem, technically.
Also, this was touched on, but I would like a bit of clarification - One
of my favorite ways to operate CW during a contest or DX pileup is to
use both the main receiver and the sub-receiver in my Yaesu Mark 5 set
to the same frequency but with different filter bandwidths, for example
400 Hz on the main and 500 Hz on the sub, which gives a quasi-stereo
effect to the sound. When using a stereo headset, the different
bandwidths make the signals seem to have a spatial differentiation that
really helps sort out the pile. The only fly in the ointment is that on
the Mark 5, you have to hold down a front-panel button to get the VFOs
to track, which creates sort of a pain where I sit. Having the ability
to have the 2 VFOs track automatically would be a big help.
I believe we can accommodate this kind of auto-tracking.
Another feature the K3 possesses is "dual passband" or perhaps "context
filtering."
This lets you set a wider bandwidth at some dB down *and* a narrower
bandwidth filter at the same time. So you could, for example, dial in a
1 kHz wide filter and set it 10 or 20 dB down and a narrow 200 Hz filter
centered on your preferred pitch. You can thus hear the signal you want
with emphasis, while still retaining some context of the activity nearby.
