Subject: TM-D700 tnc features?
I was wondering about the TM-D700, does it have hardware flow control on the
RS-232 interface?
Does it do more that 9k6 on the serial port?
Does it support extended kiss options (ack, poll, checksum)?
Any general observations and usage comments, good or bad, about the radio
are also welcome (to the group please).
Thanks for any info,
73s de Tapio, OH2KKU

The manuals for the TM-D700A are online at:
ftp://216.98.255.24/Amateur/Instruction%20Manuals/
You probably want the Specialized manual at:
ftp://216.98.255.24/Amateur/Instruction%20Manuals/TMD700A_Specialized.pdf
but don't overlook the main manual at:
ftp://216.98.255.24/Amateur/Instruction%20Manuals/TMD700A.pdf
I believe it answers all the questions you ask.
You can find the Acrobat reader at http://www.adobe.com/ if need be.

Subject: Wanted Schematics,CAT to RS232 for YAESU FT-767GX
There was an article in QST a couple of years ago, also there is one in the
past
couple of years of the ARRL manual in the station projects construction
chapter.
I built the one out of QST and it works very well.

I built an interface circuit using an opto-isolator in a DB-25
shell. You need the opto isolator, a few diodes, resistor and two
caps. Seems to work well. I think I have a hand drawn
schematic at home.
This was for a 757GXII, so it should work on the 767GX

The same is true of latitude and longitude. If I use my GPS and laptop
map software and sit in one place the spot moves all over the place. I
have seen my house move as far as 2 blocks. GPS seems to be fairly good
for tracking the location of moving objects, but almost useless for
staionary ones. I would expect that altitude would be come more accurate
just as lat/long does when moving and thus providing a greater selection
of different triangulation data from the satellites.

Is it true that there is a deliberate designed-in error to
keep our enemies from using GPS for precision military tracking
purposes?

Yes, its is called Selective Availability. It is a dither added to the
information transmitted by the GPS constellation. There is a way
to cancel this deliberate error if your receiver can receive the second
channel transmitted by the satellites, and has the decryption key to
make use of the information. Ironically, however, the times our forces
have actually been in conflicts, SA has been disabled. That's because
our military doesn't have sufficient military GPS equipment which can
nullify the SA limitations, and has been forced to use civilian GPS
receivers in combat.
A good indication that US forces are about to go adventuring
has been that your civilian GPS receiver suddenly starts giving
more accurate position information. That happened just prior
to the Gulf War for example.
Besides, our enemies can just purchase receivers that use the
Russian constellation of positioning satellites, which have never
