Can you share your GPS coordinates? I'm curious to see if there are other alternatives that would work.

Subject: [HamWAN PSDR] Connected to HamWAN on Buck Mtn, slower than desired
I have finally made a reasonable connection to HamWAN using Buck Mtn. I
am using a MikroTik mANT30 MTAD-5G-30D3-PA dish and an
RB912UAG-5HPnD-OUT radio. The smaller MikroTik dish/radio can't connect
I followed the configuration instructions on the HamWAN Website, and did
add the command "/interface wireless set 0 rx-chains=0,1 tx-chains=0,1"
which doesn't appear (probably should) in the directions. Pointing was
done using "/interface wireless monitor 0" using the fine tuning
adjustments of the mount. The best signal obtained was about -71 dB.
Let me describe the situation a bit and see if anyone has ideas on how
to improve the connection. The radio name is "K7DCJ/Brinnon-Buck", and
the system identity is "K7DCJ-Buck".
I am line of sight 2.69 miles from the transmitter on Buck at an azimuth
of about 115 degrees from true North. The problem is that I am 2 miles
away but 3600 feet below it. All the power is going over my head.
Consulting the beam patterns of the transmitting antenna, I appear to be
in the second side lobes, which is about 15-20 dB down from the maximum
power of the main vertical and horizontal lobes.
Bandwidth tests produce the following:
/tool bandwidth-test 184.108.40.206 duration=30s direction=receive
/tool bandwidth-test 220.127.116.11 duration=30s direction=transmit
The rates have gotten as high as 5 Mbps in other runnings of the tests.
Perhaps someone has an idea of how to improve this?
