mic cover for Yamaha CM500

Randy Cook-2
The little foam cover for my CM500 headset mic is ripped and I am trying to find a replacement.  There was a post about this several months ago, and I cannot find it. Part of the problem is I don't remember what the actual thing is called. Yamaha, for all of it's good products has about the worst website on the planet….

Any suggestions on a source? I remember a poster had a link to a third party who sold such things  Thanks in advance.

KPA500: SWR protection

K9QJS
Hi everyone,

Am I understanding KPA500 specs correctly?    It looks like if I were to get a KPA500 and loaded it up inadvertently on an antenna with an SWR on the high side, the KPA500 would protect me from my error by reducing power and/or faulting?    

Does this mean that the KPA500 is close to "fool proof" in protecting itself from errors that I might make?    Heaven only knows that I make enough as it is !     A different take on the same question is whether I could postpone a KAT500 purchase until later.  

Thanks in advance.

Yes.

Yes.  I have operated my KPA500 into an open circuit, and it faults and
quits making RF.  A lot of us are afflicted with the "errors we make"
syndrome. :-)

The KAT500 offers me several advantages:

1.  I need it using my large sloping Vee, and it does well

2.  I'm not enamored with SWR LED's that actually light up when I go
key-down, even if the KPA500 accepts it.  KAT500 solves that.

3.  I have 3 antennas, different combinations of bands, the KAT500 has 3
SO-239's on the back, and lets me configure which antennas will be
available on each band and which one is the preferred.

I've run my KPA500 at 500W in RTTY contests, in this last CQP, most of
the CW ops in the Alpine County expedition were running it to about
600W.  At one point, I changed bands, forgot to hit the antenna switch,
and it faulted and the ICOM 7600 folded back, all just like it all should.

I think you'll find that it is hard to break Elecraft gear.  My K3 is #642.
