I notice that in the narrower signal spectrun the two tone peaks
have the same amplitude.
Many of us have wondered why our watt meters diddled like the
RTTY tones.
Hopefully that is fixed too.
That is not fixed. I have two K3's, and have been running
reduced bandwidth firmware for a couple of months now. An LED
wattmeter still shows significant flickering as RTTY is being
sent, and screen current on a tetrode amp shows a lot of
variation on its analog meter.
What I see, on both K3's here, is a brief 7% power spike upward
when the FSK input is shorted, and a brief 7% power spike
downward when the FSK input is opened. Steady-state mark and
space rf amplitudes are equal. The transients occur only at the
transitions. This experiment was repeated with DSP v 2.81 and is
unchanged from earlier versions. I guess, if the signal is
clean, it's nothing to worry about, but it sure looks weird to
see all that flickering going on. I remember on my old TS-850, I
could check amplifier tuning while rtty was being sent, but with
the K3, I don't feel comfortable doing that.
