   This seems to be correct.  I finally got around to hooking up
my gps unit (the GPS 50) to my laptop computer, with the
idea of being able to drive around town making computer
generated maps of the area.  My unit has a choice between NMEA
0180,0182, or 0183.  It turns out that NMEA 0180 is
approximately 220 baud (as close as I could tell with a
scope), NMEA 0182 is 1200 baud, and 0183 is 4800 baud, as the
above poster suggested.  I made a level converter, but it
turns out that it wasn't necessary with my laptop. It works
fine with the data line to pin 3, and the ground to pin 1 (I
think pin 7 is probably a better place for the ground, but pin
1 was easier to remember).  It turns out, that at least with
my unit, that when in the NMEA 0182 mode, it only outputs
latitude and longitude, but in NMEA 0183 mode, it gives all
sorts of info (I haven't figured it all out yet) including
position, date, time, etc, etc, all in easy to handle ASCII
text.  It outputs a series of 7 or 8 "Standard Phrases" each with
slightly different info.  It would be nice to get a clear definition
of exactly what info is contained in these phrases.  Anyway, besides
the obvious applications of computer mapmaking and James Bond type screen
in the car telling you where you are on a map, it would sure be a 
nice easy (although expensive) alternative to the "most accurate clock". 
    One negative about the GPS 50 is that it doesn't seem to be very 
well shielded.  It sets off my radar detector, and causes quite a bit 
of interferrance in my scanners.  It doesn't seem to bother the Alinco 599 
too bad though, at least on the 2 meter band.

Subject: Propagation Announcer ?

I'm wondering if there is anything on the market available that can announce
over a repeater the propagation conditions for any given time ?
I'm considering a project that would monitor Shortwave broadcasts S/N
ratios and would drive digital canned messages concerning propagation
conditions. For example, I'm in the Middle East and want to know if there
are conditions on 20 meters to the U.S. - through our local repeater, I would
hit a few tones and it would indicate if it is receiving the VOA on 15.205
(close enough) and at what S/N ratio. The syatem would 'listen' for several
known broadcast signals and know where and when to listen.
If such a system is available off-the-shelf, I'd rather buy it.
Any feedback ?

Subject: Cushcraft R7 SWR measurements
Organization: Sequent Computer Systems Inc.
Date: Sat, 22 Aug 92 17:51:01 GMT

I have a Cushcraft R7 antenna.  This is a "no radial" vertical that
covers 10, 12, 15, 17, 20, 30, and 40.  I responded to Roger in his
recent request for information on the antenna.  He asked me about
the SWR across 40 meters.  I did not have good information handy, so
I decided to measure the SWR across the bands for him.  In the event
that others on the net are considering the antenna and want the info
I'm posting the data.

I like the antenna, it was quick and easy to install and let me get
on the air and have some fun.  I'm in the process of putting up a
tower and tri-bander, but will keep the R7.  I find that the SWR is
a bit high in places for my Kenwood TS-430S to be happy and put out
full power.  Running my Ameritron amp or using the Ten-Tec tuner
solves this problem.

The SWR measurements were made using a CW carrier of about 10 watts
and using an Autek Research WM1 computing meter to determine SWR.
This should not be considered an exact value, but should give a good
idea of SWR.  Note that the rig will start dropping power as we go
above 1.5 so the high SWR values are not precise.  The antenna is up
17 feet with the mast bolted to a storage shed (antenna is about 5 feet
above shed roof, and between a couple trees, probably 20 feet away
from them.  Note that my measurement spacings are not uniform.
The antenna was assembled as per Cushcraft measurements and installed,
no adjusting was done after that.  I generally went after the voice
sections of the band for those bands that let you center the frequency.

Dave,
  Check the filter capacitors in the HV filter. These go bad quite
  frequently. They may be breaking down at some voltage considerably
  higher than your ohmmeter will supply, so the best thing to do is
  replace them. If that doesn't work, you MAY have a short in one or
  more turns of the HV secondary. Shorted filter caps can acuse this
  also. I'm assuming that you've checked the supplies feeding the 
  oscillator... Best of luck!!!

	Pete, I have a Uniden HR2510 which is just about the same
radio.  I went to my local Rat Shack and bought one of their CB
magnetic mount mobile antennas that includes instructions for how
to cut it for ten meters.  Using my SWR meter, I got it down to about
1.2:1 or 1.3:1 at or slightly below 28.4 MHz.  If you cut, cut in fairly 
small increments so you don't over trim the whip.  I think as long as
you don't have any high-power mods done to your HTX-100, power
handling may not be a problem -I'm NOT 100% sure on that YET.....

	Anyhow, what limited use I have on it, it DOES work.  I
won't say that it is the BEST mobile antenna you'll ever 
have on 10 meters, but it is *considerably* less expensive than
many, if not most, and is readily available.

	Now I said "block". That means filter out. I did not mean
"blank". To blank would be to detect DTMF on the input and shut down
the output to prevent DTMF from being broadcast. I am assuming Gary
meant blank. I would ask him via e-mail, but have never been able to
get e-mail to him.

	What I mean is simply this: DTMF is audio band. If a device has
normal audio bandwidth, then it will pass DTMF fine. Anyone got an
argument with that? DTMF was designed by Bell Labs to do just that.

   It`s illegal to *listen* to cellular frequencies, but it is OK for your

   to anything you may hear.     Yep.. That must be it!   :-)  :-)  :-)


Yup thats it.  And if I read a recent article correctly there is a
bill pending that would close this glaring loophole and make scanners

When I bought some inserts for my FNB packs, I was told to use a heat gun
to warm up the package, then use an xacto knife to cut the newly softened
glue (the packs are _not_ welded together). I did this with my 12V
pack and made a pigs ear of it. It seems that Yaesu put glue on each
side of the cells, so that even when you've got all the seams free,
most of the glue is still in place. It doesn't help that the pack
can get too hot to hold comfortably.. Another local tried the same
tactic (after I suggested it to him) - he stopped before wrecking his
case as badly as I did. He thought about the problem, and came up with
the idea of making the glue brittle - so he put the pack in the freezer.
Once it was really cold he simply hit it with a hammer and the two
halves separated. Unfortunately, I tried this & it didn't work for me.

So there are two tales from the crypt - maybe someone can tell
us how the professionals do it :-)

Digikey can get any parts that Toko makes, even if they don't have them in
their general catalogue.  The Toko 455KC ceramic filters are okay, and they
actually do have them.  You may have to call up and ask for a supervisor to
get ordering info, though.

Now, mechanical filters are another more difficult problem altogether.  Hmm...
you could use some high speed op-amps (even the cheap AD712) to make active
bandpass filters at that frequency, which may turn out cleaner and cheaper.
