[1000mp] Key Clix Update

[frank60]

I purchased a brand new Mark V a few days ago so I have
been running tests on it using on the air checks as well as using
my FT-920 for back to back keying tests.    =20

All of the on air CW Qso were at least 10db over nine.=20
and I had them all tune my sidebands up and down=20
looking for key clix.     None of them reported anything=20
objectionable about the keying and only one said he could
he some sign of clixs out to 500hz.      On that basis you=20
you would determine that Yaesu has cleaned up the key=20
clix somewhat on the Mark V.  =20

So then I did back to back tests into a dummy load first=20
sending with 920 and then sending with  the Mark V.   The 920 was=20
clean of any key clix.   But I did detect minor clix out of the=20
Mark V out to 1khz.  =20

So the new Mark V are not the old 3khz wide clix as the=20
original Mark V put out.    Yaesu has attempted to clean it=20
up.   There were several other posts on here indicating the same
thing.   That the new production Mark V has vastly improved keying.=20
and installing the mod only improves it just slightly.   =20

I do plan on installing the mod and I'll post another update in a few=20
months when I have made more tests. =20
