Mine, too. Difficult to get these days. Once I touched the 16k Memory
extension while programming and everything was gone .... I upgraded to the
spectrum. Much later I got an ZX-80 which is the star of my home-office now.

Been a few years since I used ePMP anything. The UI
used to be dreadfully slow.

ePMP in PTP mode. You can get the itty bitty
Force180 for $85 each and in PTP mode at that range
you'll have somewhere near 200mbps aggregate.
I'm sure there are half a dozen Ubiquiti things which
will also suffice. The example ePMP below is at a range
of .559 mile.

Too much power. I don’t want to exceed 20 watts
total. So one end of a radio needs to be in the 5-7 watt
range.

Then do a 24 GHz system. That can go 2-1/2 miles
with 5 nines. Low interference. Will eat around 50 watts
at each end though.

They sound expensive.
Everybody knows 60 GHz is all absorbed by the

Not sure God would approve...

For so little throughput a 5GHz setup would be
the cheapest and probably best setup.
What keeps you from being a believer of the
60GHz? I can show you the history of some of my Ignitenet
links that may just change your mind.
Thank you,

Want it to be simple too. ONT has multiple
ethernet ports on it. Just extend those physical layer
0/1 connections.

What about a couple of 60GHz links with a
single 5GHz AP as a backup? We did this for a bank that
needed to connect two buildings temporarily. Put a MT on
either side that ran IPSEC tunnel over the link with a
failover script to route traffic over the 5 GHz link if
the 60 lost more than 50% of it's packets. The 5 GHz was
slower, but they still had connectivity in the even of a
heavy rain.

Still puzzling over how to get ethernet the
last 3000 feet. I have fiber to a point along a rural
road. The end is about 2000 feet from one home and 3000
feet from another.
Was looking at using the existing copper with
VDSL line extenders. That was what that week of math
problems was all about. I am starting to lean away from
that solution because it is old copper. I really want to
stop using it.
I don’t have a ROW that is legal. The old
copper technically is in trespass and the owner of the
property is known to be a major PITA. So not sure if I
can get permission. Even then, we are talking about 5000
feet of fiber to place. There will be some money
involved.
Using wireless could be much cheaper. Will
have to do a solar install with the ONT and RF gear on a
stub pole at the handhole.
Not sure what kid of RF. Don’t want to use
an AP because I need two layer 2 connections from the
ONT. Be more expensive to use an AP anyhow. So two PTP
systems. Rock solid, never fail type of system. Noise
floor down there is probably pretty low.
I could use a pair of rockets etc. Not
wanting to lo-ball this, want it to be very solid.
What would you use?
