It is very possible that for some countries in Europe the $1 taht is sent is
not sufficient to cover the cost of postage and of QSL cards.  I have yet to
get any cards out of F6FNU or FR5DX, but I have had no trouble getting cards
out of both Reunion Island and France with a Green Stamp.  If these cards
were being sent to Bangladesh DIRECTLY, I may understand the strick
requirement for getting the card, however, I agree that Antoine's requests
are just too difficult to manage for a young DXer as myself (not avid!! 8-)).

We must all keep in mind that this is a HOBBY and not to take too much very
seriously.

It appears likely that the Email list will be activated this
week.  It is expected to be handled by a major .edu site on
the Internet.

The list will be called:  ACC-L and will be open to all hardware
and software products manufactured by Advanced Computer Controls,
Inc.

I would think that any comparisons of other repeater controllers
specificly to ACC products would also be welcome in this forum.
So feel free to sign-up when you see the announcement of ACC-L in
this newsgroup.

If you have already asked me to "sign you up" already, then it is
likely that you will already be signed-up.  More details will of
course, be given in the announcement.

I'm looking for a hand-held mic with a built-in DTMF pad for a project

DTMF tones out the mic cable WITHOUT keying the radio.

So, does pressing one of the DTMF keys key the radio?
Does this very by model?
If it does not key the radio, are the tones available on the audio
out wire with the radio un-keyed?


Tnx,

Try putting the charger on trickle charge (you did include that feature, didn't 
you?  :)), and leaving the batteries on there for about 24 hours.  After this,
you can return them to full charge.

I've noticed the voltage-lowering behavior on gel-cells that have been drained 
to almost zero volts.  You may have to run the cells through a couple of charge-
discharge cycles before they return to normal.

I use the same charger you describe to charge my 12V 6.5AH gel cell.  Works 
great, although it gets a little hot while its charging - I modified the circuit
to produce about 1.25A peak current.

I've played with power mosfets as RF amps... I was going for
maximum efficiency so I was basically using a square wave to drive them.
I haven't tried driving them with a QRP rig with it's tuned circuit and
sine wave output, so I can't comment on that.

I actually ended up using an ICL7667 fet driver chip to drive an IRF511,
which in turn was driving a bigger fet (an IRF440).  The circuit looks
something like this:

                       +10V                     +40V
			 |                        |

	|/|             GND                      GND
         GND

    (*) - Pay attention to the power rating on this guy! ;^)

The gate capacitance of the IRF511 is no problem for the ICL7667. I think I
also had a very small resistor (a few ohms) in series with the IRF511
gate to tame things a little.

I had two of these drive circuits (ICL7667-IRF511-IRF440) with the drains of
the IRF440s connected in parallel.  At one point I had about 175 watts 
cranking out of it on the 75 meter band, although efficiency was better at 
lower power levels.  I was using it on AM (with a PDM modulator, but that's 
another story...) and I ended up running it at about 75 watts out with 125% 
positive modulation.  Overall efficiency (including the modulator) was
somewhere around 80-85% if I remember correctly.

I hope this is of some help.

The above is only an appoximation given in the ARRL manual.
It amount to about 1.41 times the height.
In actuality, the line-of-sight horizon in miles is about 1.22
times the square root of the height in feet.  This was used to
produce the table in my earlier post.  The ARRL Manual
states the distance of the radio horizon is about 1.34 times
the distance of the line-of-sight horizon.  (Can anyone account 
for the numerical value 1.34?)  Together these give the
radio horizon distance in feet to be about 1.64 times
the height in feet.  This gives values roughly in agreement with 
personal observation although the difference between it and using
the ARRL Manual approximation is probably not significant considering
the realities.   Here is a table of a few values using the 1.64
time the square root of the height formula:
   Height[feet]           Radio Horizon[miles]
       8                       4.6
      10                       5.2      Thus a mobile with antenna
      20                       7.5      at 8 ft might expect to
      25                       8.2      work a base with antenna
      30                       9.0      at 30 ft to about 4.6+9.0
      40                      10        or 13.6 mi.
      50                      12
      75                      14

     200                      23        I think this table is more

        Have you called lately???  I called yesterday (Friday) and it STILL
said November 1st.....The FCC probably won't get around to (or find the time
to...) changing the recording until the end of December or the beginning of
January.....(That's about how long it's taken for Nov. 1 update.)
        Incedently.....I upgraded on Sept. 26 of this year....12 weeks and
*still* no new call.....Why the sudden rush on upgrades??? ;-)
