Hello all,
I had a question about using a digital multimeter for
AC millivolt measures.
I have a radio shack 24-range DMM and when I set it to
mV it never seems to go to zero, its constantly
counting numbers from 30-100 mV with the leads not
connected to anything.
If I change the range to .000
Wow,
I listened to the English Tea Party. Just as I remember it (including
the SP-cops :-)). Thanks for these wonderful sounds from the past.

Chris:
A DVM has relatively high input impedance and will pick up stray 60 Hz
and other things floating around (AM broadcast, perhaps) when the leads
are open. In essence, the leads act like a small dipole receiving antenna.
Short the leads together and it should read a lot closer to zero,
Sorry, but this was raised and answered before. :-(

In the back of K7SZ's Low Power Communication (ARRL publication) is a
list of QRP calling frequencies. I am guessing that those for CW are
well used, and standardized, but I am curious, as a No-Code General,
whether the QRP SSB frequencies are used as often? I realize I am in a
minority, but

Bandpass filters, for example, operate at IF and at AF. It
would be tedious
to list which functions occur at IF and which at AF, and some
may change with
future firmweare releases.
But, it is very important important in at least two areas -- notch (auto and
manual) and noise

I have K2/100 #3132 with the 160m, SSB, and DSP modules installed. I am

power source is a battery that is being charged as I am operating. My
antenna is a Zirpel (like a Carolina Windom). The KAT100 is able to find

Guys - We can't release actual numbers for competitive reasons, but I
can say that the numbers quoted below are incorrect.
We increased the first July-August production run above the numbers

Also, we are NOT sold out of the Sept-Oct production run. :-)

Hello
I was given both a KDSP2 and the KAF2 for my birthday by the xyl. Since I
can't use both
in my K2, I have deicided to sell the KAF2.
It is still in the un-opened package, and will ship it for $65.00 to the USA
only. If interested

Well, I think I have this one sorted out. Here's how it boiled down
for me, in case anyone else gets anything similar:
1) Reflowed *every* solder joint on the filter board. Added a bit of
solder to the ones that looked like they could handle a little more
2) Reinstalled the filterboard and

Here is a review of the MDR-NC50 -- They say its pretty good but apparently
needs some oomph to drive them and not great for MP3 players which don't
have a lot of output:
