It says that the frequency range on the VHF model is 148-174MHz. Not
so useful for APRS :-)
Since they don't mention power consumption, and they're promoting it as a
stationary or vehicle mobile device, it would probably be a big battery
hog.

I think Steve has a point here....his ERROR'S page succeeded in removing a
lot of people who were not configured correctly! Heck even got me of that
list pretty quick! <BLUSH> and I never gave over my $100 buck bet (Sorry
Steve) <G>
The "offenders" were not removed, but they fixed their own problems in order
to get of that list!
Like "hooked on phonics" it worked for me! <G>

Actually a TNC and KISS EPROM are not required to run Digi_Ned.
The Tigertronics BP2 $xx.xx and BP2M $xx.xx both work right out of the box
with the Digi_Ned Digiflop program setup disk. I have three Digi_Ned
digi's up in Georgia that use KISS TNC's and if they fail I will be
replacing them with the BP2's. The entire system can be built inside
virtually any computer case. I usually just Velcro the radio bracket on top
of the computer case.
I have not tried it but I think the TNC-X may also work for about the same
price range.
The beauty of Digi_Ned is that it lets you experiment endlessly with minor
path tweaks as well as giving virtually unlimited LANn_n and Firewall digi
capabilities. A very simple one is to use the state abbreviation as a
Flood path. This allows you to limit the WIDEn-N if needed. Digi_Ned can
also respond to user inquires about the correct local path.
WIDEn-N How many hops do you want? Its your choice.
TRACEn-N How many hops do you want? Its your choice.
GAn-N How many hops do you want? Its your choice. Plus it should stop at
the state line.
I plan to experiment when I get enough Digi_Ned digi's up with things like:
GAARES
GEMA
NWS
I want to see if I can make these work using the preemption functions to
replace the path with a direct digi path perhaps with a built in
redundancy. Not sure if I can do it yet but it is interesting to think about.
A packet with one of these pseudo paths on the end would be rerouted when
it hit the Digi_Ned digi with the direct digicalls along the best path or
paths as well as being sent on a generic path.
Actually I had an idea once that the solution to the long path problem was
to separate the RF path from the internet path by letting the user declare
their intent using pseudo digi's on the end like NOGATE IGATE OR INET. If
these pseudo digis aliases were programmed into Digi_Ned the packet would
be routed as the USER intended. This process would be transparent to the
non Digi_Ned digi's.
RELAY,WIDE3-3,INET would provide the same functionality in a non Digi_Ned
area as RELAY,WIDE3-3 does now while implicitly allowing Digi_Ned SYSOPS to
modify the path to reach the nearest IGATE while minimizing the impact on
the local network.
So here is the deal $50 for BP2. $8 for serial cable. $xx for old 386-486
computer. So far I have not paid a dime for one yet YMMV. = True
intelligent digi that is suitable for any site with AC power. Setup time
assuming no OS on box clean MS-DOS 6.2 or similar OS 15 to 30 minutes.
DigiFlop install is less than 15 minutes. I have done it is less than 5.
So a whole system integration can take less than one hour.
The alternative:
TNC-2
USED Hamfest ~$50 - 75 + new UIDIGI EPROM + SHIPPING AND TIME if you don't
own a programmer.
NEW MFJ-1270 $169.00 + new UIDIGI EPROM + SHIPPING AND TIME if you don't
own a programmer.
Please note I am not biased against UIDIGI I simply think that if a site
meets a few simple criteria Digi_Ned is a better solution.
These are AC power and a secure location with some minimal climate
control. I think that the many digi sites meet these criteria. However,
for those that don't UIDIGI is far and away the best alternative.

Perhaps Steve could combine the suggestions of IGATE control and an error
page in a non-punitive manner.
Bob's local IGate idea could be modified to inject something that Steve
could parse.
Steve could then cause parsed packets to be directed to a OOPs page with
links to Bob's errata site. The page should also list what IGATE triggered
the OOPs. Then at the bottom would be a link to the normal FINDU page.
This combines Bob's idea of local IGATE SYSOP control and harnesses the
global reach of FINDU in such a way that we can Elmer hams in a
non-punitive manner.
Perhaps if the IGATE software could be rewritten to allow the local SYSOP
to do path substitution of the last digi with 'OOPS'. This does not
penalize the user with a non-plotting posit by obliterating his data yet
provides a way for local SYSOPS to comment on bad user behavior. The only
user penalty is an extra click.
If this is way off base just ignore me; I have been awake almost 28 hours
and am now off to bed.

If you think of WIDE 7-7 as excessive power for communication then it is in
violation of the FCC rules and could be reason to alert the FCC for their
comments. If you were to use 500 watts to communicate voice 2 blocks away
it would be as excessive as WIDE 7-7 in 90% of the applications.
Wait...don't get the FCC involved, we should be self policeing.

Hiya John,
Typically British!
Whilst there's no law to stop you putting a GPS/D7/Radar detector on the
dashboard, if you're involved in an accident the law will frown upon all
those distractions, and it will have a bearing on the outcome.
Interestingly.. until recently it wasn't illegal to use a cell phone whilst
driving, it is now.. although radio hams (but not CB'ers) can use a fist
mic whilst driving.
But the police have this great way of prosecuting pretty much anyone for
anything, by stating that you're "driving without due care and attention".
In fact, you can be prosecuted for drinking water, from a bottle, whilst
stationery at traffic lights! Incredibly British eh.
As for the camera position files... not a chance of getting them. It's this
file that enables the producers to charge xxx for what is just a GPS
with a different range display!

I've seen reviews of the BP2M, but no explanation of how it works. Does it
actually have some sort of multi-mode modem chip? Is it just an A/D
converter with host software that performs the signal processing? Does it
use a DSP chip?
