Friends,
My truck (Yeti) was hit Friday night. Everyone was OK, but the other
driver's car was obviously totaled. This morning I just took Yeti to
the body shop for the insurance-company-approved estimate, and it came
in at well over $11,000. So the likely scenario is that they will total
it out. Therefore, I'm starting inquiries to see if anyone might have a
decent-sized 4WD vehicle for sale. Ideally it should have high ground
clearance, and able to make it to Conrado Castillo, for instance.
Please contact me off list if you have something that I could consider.
My cell # is 512-663-2287. Gracias, amigos.
-- Jim

"A few years ago, there was a post about walkie-talkies and how the package
advertising was claiming 8 mile range and others claiming up to 16 mile
range.
Since then, the numbers have gradually increased.
Now, similar radios are claiming 36 miles of range on their
product advertising.
Yet the wattage doesn't appear to be different.
Has anything changed ?
Here is an example:
http://www.midlandradio.com/Two-Way-Radio.BS3/GXT1000VP4";
Yes, the promotional folks are very ambitious and have recently moved to
Texas.
At the bottom of the link above is the qualifications to their distance
claims:
*Maximum range can only be achieved over water or open rural areas under
optimum conditions. FCC license required. Features and specifications subject
to change without notice."
The 400 MHZ frequency is generally line of sight. With a tiny antenna you
will not get these maximum ranges for the average communication situation.
Get on top of a high spot like a mountain, tall building or better yet be
in outer space, then you will get good distance.

I have 4 of the Motorola radios and a license to boot. They are usually
good for a couple of miles in the hill country. I haven't really tried them
out on open ground though I'm sure someone on this list has.
It's possible the Midland radios have a greater range, they have a larger
antenna. Depends on how well the length of the antenna is matched to the
frequency. I'd sure question 36 miles however!

36 miles is easily reachable, of course on UHF and VHF this would have to be
a direct line of sight.
Most aviation UHF and VHF radios are only 10 watts..and have a line of sight
range of over a hundred sixty miles. Good line of sight from 30,000 feet.
On the ground you might get a half mile to three depending on the terrain.
Unless you were on the side of a mountain talking to someone in the valley
or on another mountain. In that case I could see 36 miles could be
possible.

We just got a pair of Motorola Talkabout T9500XLR radios from Radio
Shack. They work with NiMH rechargeable or alkaline batteries and
includes a NOOA weather radio. They claim:
Mountain to valley of up to 25 miles
Lake (over water) of up to 10 miles
Urban up to 2 miles.
They have a "power boost" feature that increases the transmit power
to the GMRS/FRS channels (Channels 1-7, 462.5625-462.7125 MHz) and
the GMRS only channels (Channels 15-22, 462.5500-462.7250 MHz). But
the Tx power for the FRS only channels (Channels 8-14,
467.5625-467.7125 MHz is only the "low power". (Note that adjacent
channels are not adjacent frequencies.)
We recently tried a mountain-to-valley transmission (Sandias) that
was not quite line-of-sight (some mountain was in the way) and the
distance was about 4.6 miles. It barely worked. Perhaps a line of
sight link would have been better. The problem is that when you are
receiving on the mountain you are up high enough to receive
everyone's transmission so choice of channel is important.
Do various cave projects have specific frequencies / channels that
they use in the field?
