> If he travels to East Texas he will need all the hops he can get! LOLA quick look east of Dallas shows that just about all of the
digipeaters visible are getting into an i-gate direct. Only one is
using 1 hop to get to an i-gate. That means, if you can be heard by a
digipeater, at most you will need 2 hops to get to an i-gate.
Now, there is a big hole where there are no digipeaters... you could
ask for 7 hops, but with no one hearing you, it really doesn't matter.
Going into an area with no one listening, it makes no sense to
increase the number of hops requested.
The solution to the issue is to build more digipeaters.
Have a look at Alberta east of Edmonton
and compare with the area east of Dallas.
Try going into the filter and shutting off all stations but the
digipeaters and i-gates, and turn on the terrain map.
You'll see that the similarities between the areas are quite astounding.
Hover over the digipeaters and have a look to see where they send
their signals, and get gated via.
Texas has far more i-gates than we do, but we have little problem
getting packets into the internet from anywhere on the map. 2 hops
will get you heard.
If you compare the urban areas of Edmonton versus Dallas, you will see
a huge difference. Edmonton has a single digipeater (VA6KRM-10 which
is also an i-gate), whereas Dallas has around 23 digipeaters within 50
Congested areas with heavily overlapping digipeater coverages suffer
from network reliability issues due to all the collisions and packet
The solution to correct a noisy area where everyone is stepping on
everyone else is NOT to add more overlapping digipeaters...
