[HamWAN PSDR] HamWAN PSDR Internet performance

[David Giuliani]

Hi - I’m new to the PSDR, and could use some help getting my HamWAN connection going.  I installed a Poynting + Mikrotik Router Board system on my roof, and configured using the Wiki, no problems.  I’m getting strong signals between my QTH at north Mercer Island and the Capitol Park station:

Connected to ess, CapitolPark-S2/AE7SJ
nv2
Signal: -68dBm
SNR 51dB
Tx: 16.2Mbps, 96% ccq, 16.2Mbps
Rx: 16.2Mbps, 96% ccq, 16.2Mbps

However, I get sporadic Internet performance, measured using Speedtest.net.  Here are a few readings this morning:

ping    down  up   
21ms   3.9      2.8
35ms   <0.1  stopped
77ms   0.27      0.46
42ms   2.0      0.1 

I did check my cabling between the radio and the computer by substitution - no change.  

Two things:
1.  Anybody have any suggestions? What data rate are others of you getting?
2.  Is there a place to go to get help on subjects like this?

Thanks,

It can't be as boring as water drying out of connectors, since that would take a long time and not exhibit a sharp spike like that @ 1AM.  Perhaps a wind gust blew the dish back into position?  But that wouldn't account for the very slow rise in signal after the sharp spike.  So confused.  Theories welcome.

I tried to see if trees fell in its path, but the dome is too iced up in that direction to tell.  Still waiting to hear about damage on the Queen Anne side.

We are still routing 100% of HamWAN!  On the down side, we just burned through all our redundancy, and the next link to go down will cause an outage somewhere.
