Back in my county-hunting days I had purchased, from somewhere, a poster
size black on white map of the continental USA with all counties shown. As
each county was confirmed I could "color in" that county with a felt-tip
marker. So I could quickly see if I needed a county heard on the air.
Is anyone aware of a similar commercially available map for the USA that
shows grid squares which could be colored in as they were confirmed? How
about for Europe or other areas?
Thanks.
Tom, K?TW

Try DX Atlas....
it is not printed but you can track all contacted and confirmed grids with
different colors... also it counts both cases....

Tom, I believe that the ARRL is still publishing a book that has the
grid squares for the entire world.
Might be a bit of an overkill considering what you are looking for but
that is your call.

The ARRL also has a nice wall map with the North American grids.
If someone could do one for AMSAT, it might be a good fundraiser!

Its still up !!
Space Track elements for 07:24 this morning (October 21st) assign a Mean

and they have revised their re-entry forecast.
Unless something unexpected happens it looks like the only?serious contender

Well, the best info source for Kenwood-Amateur/US is still out of the
office with a back injury. Leo might be back in a week or two ...
Personally, I would be surprised if Kenwood dedicated a lot of
engineering talent to a new, true full-duplex amateur handheld. The
profit for them is not in the amateur world - but in the land mobile /
commercial arenas.
I hope I am wrong, though!

Thanks to all that responded to my post
I'm looking for something along the size of the grid map that ICOM supplies
(12" X 7") but in black and white so confirmed squares could be colored in.
The 8 1/2" X 11" maps that I've found online seem too small and the
resolution is not good. And, although ARRL chose to show only the cover of
it's grid square book, I think the pages inside are in color(?).

At Dayton 5 months ago, Kenwood had posters in their booth
announcing a new HT and HF transceiver for the summer of
2010. Of course, there were no details released at that time
for either radio.
If Kenwood is simply updating the design of the old TH-D7 to
be this new HT, that might be their way to minimize R&D costs.
If they are able to replace the component(s) no longer in
production with others, they may not make many other updates
in the interests of saving money. The radio was still popular until
it was discontinued, and remains popular on the used market now.
I picked one up at a hamfest 3 months ago, and still need to make
time to play around with it.
When the TM-D710 and TM-V71 mobile radios were released,
Kenwood only developed one radio "box" for both of these models.
They share the same FCC ID number, and the RC-D710 adds the
TNC functionality to the TM-V71 (the RC-D710 does not attach to
the TM-V71, unfortunately). Kenwood may be trying to stay in the
amateur market, without spending lots of money to do so. It will
be interesting to see what this new HT looks like, whenever it sees
the light of day (or when someone puts photos of it online).

To the gentleman desiring a non-color grid square map ...
You can download the Icom grid square map as a .pdf at ...

... then print it out grey scale ... or otherwise manipulate it in
your favorite image/paint program!

Hi Bruce,
I am afraid you are very much mistaken in your logic here.
For mode J on AO51 say, The 5W signal you transmit on 2m will
completely drive that 70cm preamp between the antenna and duplexer
into saturation unless you put a very good filter on the input
(the desense issue). That insertion loss might negate any gains you make
on the preamp, increase your noise floor by 20dB and add a lot of hassle,
and more importantly weight.
Actually, the 1.2dB insertion loss is better than I was expecting
and good enough for the short cable run to the HT. It is what it is
and its good enough for the job it was intended for.

I'm grateful to everyone who has contributed to this discussion.
It strikes me that the greatest improvement we could make to hand-held
yagis would be to somehow integrate a low noise preamp circuit very
close to the 70cm port. I have an indoor-style ARR preamp that I've
thought of connecting to the boom with cable ties. A powersupply using
AA batteries and a DC to DC buck-boost chip from, e.g., Maxim, would
keep the whole thing light. (Alternatively, I see that the max voltage
for my ARR is pretty high: I might get away with a pair of Nicad '9v'
batteries.)
Like so much of amateur radio, it's more of a challenge of
construction than anything else.
Has anyone experimented with this sort of improvement?

Tom,
I have a copy of the ARRL grid square atlas, and it's all black and white
inside. It shows the entire world, which is helpful for some of the grids
you can work on some satellites that are outside what a U.S. map would show.
That being said, the grids are very tiny in the atlas.
I have a black and white map I can email you. Contact me off the BB if you'd
like it. It's a U.S. map.
73,
Tim - N3TL
