The Kenwood D7 APRS HT and D700 and D710 mobiles display
gridsquare directly (assuming a GPS is plugged into it. The new
D72 coming out in the next month or so has the GPS built in,
making for a trivial package to carry.
I had assumed that the Yaesu VX-8R, DR, and GR APRS HT's also
read out directly the grid square? But your next sentence seems

What is this 'GPSMAP76S'??? If I am understanding correctly, it plots grids
on the GPS screen? If so, is this software or a separate GPS receiver? I
have a Garmin Venture HC, would it be applicable to it? It would be a lot
easier to look down and see what grid you are in on the display rather than
calculate it using lat/lon.

I have a Garmin GPSmap 76 that is in excess to my needs. It displays Grid's.
It comes with a serial cable, and possibly a mounting bracket(if I can find
it). I will sell it for $120, which includes shipping. I will also donate
1/2 of my net from the sale to AMSAT.

Several have reported to me that some of my grid-boundary expedition
QSL cards were questioned by VUCC card checkers, even with the
GPS latitude/longitude readout printed on the card. I have never been
contacted by ARRL to provide any documentation regarding my grid
expeditions, but there's always a first time for that in the future. I
prefer to be safe and have all of that with me, than not have it for the
one time I may be called upon to provide the documentation.
As for Don Miller, yes - I am familiar with his escapades. When the
VUCC rules were updated in late 2008 to coincide with the new Fred
Fish award for 6m, I made sure to understand them and comply with
them for anything I did after that point. I don't want other satellite
operators to lose credit for grids they worked me in and have my
cards for.

Zack,
I used to have a old Garmin GPSIII that would display maidenhead grids.
Used it when I would rover in the VHF contests. Very simple to use and
very very cheap now on the used market. It's OLD technology but I don't
think anyone will fault you for using it even if it isn't as accurate.
It'll get you close enough and to me as long as it shows the grid that
you are passing out on the screen then you've made a "good faith" effort
to do things right.
BTW: Nice to work you on SO-50 the other night. QSL will be in the mail.

Unfortunately, Yaesu did not choose to provide a grid-square
display on the GPS for any of the VX-8 handhelds. I have not
seen the FTM-350 with its optional GPS, to see if it is any
different than the VX-8 radios. The displays for the VX-8R I
previously had and my current VX-8GR shows the latitude
and longitude, speed, altitude, time, a compass heading, and
how many GPS satellites are being used to determine your
location. It would have been nice to have the grid show up on
the display (possibly by a turn of the VFO knob, similar to
how you bring the time up on the GPS display of the VX-8GR),
but I'm Ok with what I get on the VX-8GR display. For its
intended purpose, the VX-8GR is perfect as is. I can use my
Garmin GPS to figure out where the grid boundaries are.
73!

The Garmin GPSMAP 76S is a discontinued GPS receiver:
https://buy.garmin.com/shop/shop.do?pID=183
I can make its main display show either my latitude/longitude or a
grid locator. No need to convert latitude/longitude to grids or vice
versa. Many Garmin GPS units, and some from other manufacturers,
have this functionality.
In a quick scan of the PDF manual for your Venture HC GPS, the
word "Maidenhead" - the fornal name of the grid-locator system -
did not appear. It doesn't look like you can make your GPS display
the grid locators directly. It does have a screen where it shows the
latitude/longitude and accuracy figure, so it could be used if you
took the pictures to document your location on a grid boundary or
4-grid intersection.
