The calibration difference is documented in their API reference. I run a
Davis Weather Monitor II, I ran into the variance pretty much from day
one. My field elevation is about 580 feet so it is a fairly respectable
calibration difference, dont remember the exact amount but it is enough
that it would not e acceptable to me.
I run Linux boxes and wrote my own code to poll the Davis equipment,
store the values in my own database and forward it to findu and
wunderground. When I initialize the program at start up one of the first
things I do is interrogate it for its calibration values. The monitor II
also has a calibration value for outside humidity (I think) been a while
since I needed to be in the code.
It really surprises me that their pclink software doesnt take that into
account.
I realize this probably doesnt help you, just letting you know what I
did to incorporate a davis with my igate.

Parallax is the exclusive supplier of the Grand Idea Studio Emic Text to
Speech Line. This SIP module will let your robot speak, provide a real
human-console interface to your control system, or simply provide some
entertainment to your BASIC Stamp microcontroller projects. Based on the
Winbond WTS701, this device intelligently handles values, sentences,
numbers and common abbreviations with an extremely natural female voice
with simple serial string sentences.
Here is a sample of the speech quality...

Very interesting.
Speech seems to be making another comeback.
I've seen a couple of speech products recently, most phoneme based, as this
one appears to be.
I just recorded some repeater ID's with it, might try them out this week.

Or have both! Leave the optional !XYZ! on the plain-format and MIC-E, and
still require WGS84 on the base-91 format (Making !XYZ! pointless for a
base-91 transmission since the datum ik known by specification).
That way we have at least 1 reliable datum format with high precision for
those applications and situations that realy need it and that is available
today in all implementations that support base-91 posits.
But hey, I said it was a *compromise* to bring both camps together in a
proposal acceptable to both. Of course compromises do not work if you only
want to stick to your own original proposal.
Kind regards,
Henk.

John,
Can't speak to the TM-V7A cables, I don't have one. If you want to get
together we can compare my D-700 to your V7A and see.

Here is one that has more voices, and some sound a bit better. You can
easily download the files for playback too (click the display link box).
This is an easy way to add special announcements in your APRS programs
or repeater DVR.

No, the cables are no where close, between the V7 and D700.
You will need to install the D700 cable.
