ARRL have *never* made a coherent proposal that included regulation by
bandwidth. The only time they proposed maximum bandwidths for specific
modes they screwed it up so badly that it languished for several years
and ARRL withdrew their proposal.

The Commission has never taken a stance on either regulation by
bandwidth or regulation of bandwidth. Their only (private) statements
is that they are waiting on ARRL to provide a coherent proposal that
represents a consensus among all stake holders.

Have I misunderstood the above? I would find it very surprising that the FCC
does not specify bandwidth limits on signal in the amateur bands, regardless
of mode. IIRC, there are limits set on signal bandwidths in Canada.

Hi Ron,

Fear not, my spelling is quite different to US English. Never had a problem.

On another subject. KH1 was #331 mixed for me. I started from zero in
mid 2000 after a spell of about 10 years QRT. The first 257 were with
the K2. All have been worked K2/K3 and for the first three years only
made about 500 QSO QRP to a low wire and less entities than is possible
over a major contest weekend.

Now rather more tooled up!

Regards,

Mike VP8NO

Re: help wiring a mic?

You guys are all brutal! :)

This is a hobby that we try things and see how they work and if it doesn't,
then you learned something. Ham Radio is an experimental hobby or did we
all forget that.

All you audio engineers didn't get where you are today without going
through the school of hard knocks. Why not help him out so he can learn
something. BTW, the KOSS SB40's are really bad. All bottom end and little
highs. Maybe the 2 I have are defective.

I have one of these mics and I use it for several uses, but I have also had
it on my Flex and it sounds darn good and for the money while running
SmartSDR remote and using PC Audio. I would recommend it for someone on a
budget. I guess I'll have to wire it up for my KX2 and see how it works.
There might not be enough BIAS voltage as other had suggested.

Re: help wiring a mic?

Has anyone here provided any information on how to wire XXX mic to a KX3?

We’ve all read various dissertations on how the mic is good/bad or just wrong for the use.

I bought a similar mic from eBay and bought a cable from Radio Shack and a Behringer Phantom Power supply(cost more than the mic!). Had a Heil cable to use from Behringer unit to K3. Worked pretty well. Now use a PR77d on the K3S (I know, overkill but I like the look of it).

wunder,

I have 2 CM500 headsets, and neither of them have "KOSS" on the mic plug.

Re: help wiring a mic?

In reply to this post by Jim Brown-10

but for 18$,,, including the suspension....
it looks soooo cool.....

i bought a similiar if not identical... from banggood....

it plugs right into the mic jack on the back of the k3 kx3 .... so
much for 'studio'
Me thinks it is for computer video gamers and bloggers.

and it works just like every other electret....

cut off the bottom response...
