My guess is that they are that bad.
Luckily, the ones that are hot-switching their relays won't be on the 
air for too long. At least, not with high power.

Yes, I watched one yesterday in a pile-up and I could could hear the
sparking.  The signal was about a kHz or more wide.

I've noticed that it is directly proportional to the signal strength, 
but some ARE that wide (one brand in particular is more offensive).

The old FT-1000D is notorious.  (I have one.)  I'm not sure about the 
MP.  There's a mod, which helps, but it's still wide.  It's a big reason 
I bought a K3.

I have a screen capture from the P3 with a CW signal about 15KHz 
wide during straight key night. He was calling CQ, but I didn't 
copy the call sign. I suspect a boatanchor in very poor condition.

Yes and no. We must learn to understand the P3 display. It reads the 
voltage at the antenna input vs frequency. A stronger signal produces 
more voltage at every frequency at which it generates sidebands. What 
tells us bandwidth is the DIFFERENCE between the peak of the waveform 
and the sidebands, and to get a good read on that, we need to put the P3 
in PEAK mode. The problem is that it's tough to do that in a pileup, 
because all the other signals are contributing to what the P3 sees in 
the sidebands.


Yes, some of those signals ARE wide, some are VERY wide. Many DXers only 
get on the air for DXpeditions to rare ones, many are OTs with OT rigs. 
:) There's one of these (but a contester, not a DXer) about 2 miles down 
the road from me. He only works SSB DX contests, and he wipes out the 
entire band with the trash from his rig. The good news is that he has an 
alternate QTH 20 miles down the coast, and since I moved in ten years 
ago, he now contests from there. :)

I think your P3 is OK.  I believe they are, for the most part, really 
wide.  Since I've been operating remote to W7RN with a very high 
coefficient of airborne aluminum, I've discovered that the better the 
antenna, the high the Key-Click volume on the band.

And with some that seem to run their radio in QSK mode, but without a
