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 reliably. 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 44.25.143.94 duration=30s direction=receive status: running duration: 24s rx-current: 2.9Mbps rx-10-second-average: 3.5Mbps rx-total-average: 2.3Mbps lost-packets: 120 random-data: no direction: receive rx-size: 1500 connection-count: 20 local-cpu-load: 3% remote-cpu-load: 5% /tool bandwidth-test 44.25.143.94 duration=30s direction=transmit status: running duration: 27s tx-current: 2.5Mbps tx-10-second-average: 2.3Mbps tx-total-average: 2.0Mbps random-data: no direction: transmit tx-size: 1500 connection-count: 20 local-cpu-load: 4% remote-cpu-load: 3% 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? 73, Dave K7DCJ
David, Can you share your GPS coordinates? I'm curious to see if there are other alternatives that would work.

I and others have looked into this, but you are welcome to try it too! 47.73522, -122.87424 elevation essentially 0 I am on the water at Jackson Cove, on Hood Canal. I am in the middle of a dense, 150 year old forest. The only possibilities are to be on the very edge of the water, facing East North East, or on the West end of the property where Buck Mtn just peaks out above Turner Mtn. I have tried Gold Mtn, but I would have to be out in the water to get an unobstructed view. Getting from the water back to the compound is actually harder that the current setup. The current setup is not simple. The dish/radio is located on top of my pumphouse, with power, looking up over a pasture (no trees) to Buck Mtn. A VDSL connection goes from the pumphouse 800 feet underground to a transformer site, where it goes 70 feet high overhead to a garage, and then 80 feet underground to my shop where the VDSL ends and connects to my Internet Central. It is then distributed on its own network throughout my compound. Test results directly at the dish/radio and at other places on the network are the same. Other tests show that this setup is not limiting the bandpass received by the dish/antenna. Cutting down trees is not a possibility, unless they are sick and represent a danger. We are in the middle of a Bald Eagle Zone with strict limitations on what we can do. One of the cons of living in paradise! I was hoping I could make a configuration change to improve the current connection? 73, Dave K7DCJ On 11/7/19 7:01 PM, Rob Salsgiver wrote:

Unfortunately the only way to fix the RF path would be to down-tilt the sector at the expense of clients further out. The best solution might be to put an additional small panel with greater down-tilt as somewhat of a point to point connection. That probably wouldn't be able to happen until next year, and we would need to confirm with the site we're ok to add another antenna (possible, just hasn't been asked). I don't know of any configurations that would make up for RF path weakness. Rob -----Original Message----- From: David C.

Dave, Give it another try. I found that the Buck sector was set to the older 5MHz channel plan. I’ve bumped that to the current 10MHz plan and am seeing ~20/10mbps to/from your modem, which is pretty reasonable. Nigel

Odd, IIRC we’ve seen other reports recently of bandwidth-test reporting slower figures from the modem, than the same test from the sector side. I’ve also seen instances where bandwidth test got CPU or other local resource bound, and didn’t accurately reflect the actual link, so I tend to use bandwidth test as a helpful tool but not the final indication. No, there’s no configuration change needed on your side. A speedtest out to the internet of 5/5 is reasonable. Ideally a little faster, but certainly usable and well within the “multi-megabit” mantra. Nigel

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 44.25.143.94 duration=30s direction=receive status: running duration: 24s rx-current: 2.9Mbps rx-10-second-average: 3.5Mbps rx-total-average: 2.3Mbps lost-packets: 120 random-data: no direction: receive rx-size: 1500 connection-count: 20 local-cpu-load: 3% remote-cpu-load: 5%
/tool bandwidth-test 44.25.143.94 duration=30s direction=transmit status: running duration: 27s tx-current: 2.5Mbps tx-10-second-average: 2.3Mbps tx-total-average: 2.0Mbps random-data: no direction: transmit tx-size: 1500 connection-count: 20 local-cpu-load: 4% remote-cpu-load: 3%
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?
