Saw this posted on the bulletin board of a local ham store: An ARRL-
produced program, "The New World of Amateur Radio," will be airing on
PBS the week of Jan 7.  Locally, in the S.F. Bay Area, it will be on
at 7:30 on Jan. 7, on KQED.  Hope this was not last year's notice :-).
Anyone know for sure?

This is current information.  Randy, KK6BO, who is the Public Information
Officer for the ARRL Santa Clara Valley section has been touting the
showing for a couple of weeks locally. Its also going to be shown on KQEC
at a different time but I don't recall when that is...anyone else have
a better memory than myself?

How about a new license class for CW gurus:  CODE MASTER class, where one
only needs the general theory, but passes 30 WPM to get access to the Extra
portion of the CW band (but not any other Extra privs and not the calls).

Ya know... the expanding packet radio usage is impacting existing CW usage
more than it is impacting voice.  The sharing of CW and RTTY/digital is not
necessarily so good an idea.

Maybe we should have specific subbands for certain traditional modes, and
open the rest of each band for bandwidth limitations only.

How about some spread spectrum, too?   Seriously!
But this will complicate the rules on bandwidth limitations.  What measures
exist for efficiency of SS emissions?

Message-ID: <[e-mail]>

I am interested in finding a radio to listen to foreign short wave
broadcasts.  I have, as yet, little experience in costs and availability
of radios.  Can anyone E-mail me advice on sources of used and fairly
inexpensive equipment that will allow me to get started.

                    MODS FOR ICOM 32AT

1.  Remove battery and antenna.
2.  Loosen two screws on top of unit as much as possible without removing them.
3.  Loosen 4 flat head screws on bottom of unit 1 turn.
4.  Loosen 2 screws near PTT switch 1 turn.
5.  Remove 4 black screws on back of unit.
6.  Lift bottom of front cover .25 inch, slide it down .25 inch, then lift
    front cover up 1 inch.
7.  Disconnect plug on 4 wires coming from the speaker.
<< THe flex cable can be disconnected from the main board by gently
pulling up on the ears of the connector for that cable on the main board>>
8.  Lay front panel on table up-side down being careful of the flex circuit.
9.  All mods are done to the back of the front panel.  Notice places for 5
    axial diodes, which I will call 1 through 5, 1 being nearest the display.
<<These are on the right hand side of the back of the front panel>>
    Add/remove diodes so there are diodes in positions 3 and 5.  This will
    open up receive coverage for VHF & UHF and enable keyboard entry of the
    10 MHz digit.
<< I seemed to have the same coverage with and without diode #3 installed>>

   When you go out of the range the radio will receive a U appears in
   place  of the memory channel number.  It means the PLL circuit has
   lost lock and the radio will not work.

10. Notice 4 surface mount resistors slightly left of center directly
    above the speaker, lined up in a row.  Solder the anode (the side
    without the bar) of two diodes to the right side of the lower of
    the four resistors.
<<I followed the trace to an small unused pad to the right, and used
that as a connection point.  The rightmost pad of the 5 diode pad set
on the lower right of the CPU board is also connected to that trace.>>
    Now find the CPU.  It's the PGA under the shield near the top of
    the board.  Find the row of pins on the CPU nearest the speaker.
    Notice the the 8th pin from the right has a thicker trace coming
    from it.  Now notice that there are small solder pads about .25
    inch toward the speaker on both the fat trace and the two traces
    to the right of it.  Solder one each of the cathodes of the 2
    diodes to the solder pads on the two smaller traces.
    This will open up the transmit for VHF & UHF.
<< Oh yes, note that memory channels clear when you do these.  And the
<<right diode opens xmit on VHF, the left on UHF.  You should probably
<<do a microprocessor reset when you power back up. >>

11. Put unit back together in reverse order.

     This procedure worked for my unit, but I can't guarantee it will work
 for yours.


<<After the diode is installed in position #5, this will work>>

Last but not least to enable cross band repeating first choose a pair of
frequencies with the two vfo's for VHF and UHF.Then press and hold function
key while pressing  with the other hand the following "C" "6" "D". The radio
will start scanning the two frequencies continiously, if a station is heard
in one of the two it will retransmitted from the other! The two frequencies
must be simplex, no cross band repeaters yet sorry!

Subject: Sommer antennas - info wanted
Message-ID: <[e-mail]>

The new request for rulemaking by the ARRL to allow AUTOMATIC CONTROL of
HF Digital Communications is a proposal much needed.  HOWEVER, I am
concerned that the "CW Good Ol' Boys" have influenced it improperly in
one regard; The proposed sub-bands are far to small.  10Khz. on the more
popular bands is just inviting an unusable system as demand for HF
digital relay requirements increase.  I think we should open the entire
General/Advanced CW sub-bands to Automatic Digital and Half of the 10M
Novice subband (Maybe we require Tech or Above license in the novice
subband).  If not the full subbands then at least half.  This leaves the
Extra class segments for CW and attended Digital  -- This should leave a
good "incentive" for CW users to upgrade to Extra.

Also this same rulemaking should be the place where we change the
transmission SPEED rules to BANDWIDTH rules.

Perhaps we create higher bandwidth subbands in some of the Automatic
Digital subbands.

Comments?  (Send them to the FCC as well)

TexNet is an interconnection alternative. It provides (at least in the
implementation here in the Dallas area) multi-user connects, Message Service,
conference bridges, trunking to other cities, and a National Weather Service
database.

Drop Greg a note or Email, he can get you detailed information.

Why not?  There are folks out there who insist on having their net/QSO on
THEIR frequency, no matter what.  If someone else is in their, tough.  Just
QRO and pretend you can't hear them.

Not everyone's like that, fortunately.  FOWO (From One Who Knows) - I run
