I posted the note below on the 3830 list in my report on results CQWW160. Today I investigated the problem and discovered the problem existed on 80&40M as well where I use an OCF Dipole with a 4:1 balun and separate home brew toroid choke. On 160 I Use a backyard Inv L with 30 radials of Random lengths and a ferrite bead choke.
The Gateway Router is installed in the wiring closet near the shack where the AC entrance and breaker panel is located. All the CAT5 wiring for the house also terminates in this Central point for connection to the router. I used the SPEEDTEST.NET site to monitor the High speed line as I adjusted the power in these antennas. On all three of these bands the line would Crash at 100 w output. The crash on 80&40 was dramatic whereas on 160 the line ( router) would stop And then try to recover indicating that the impact of the RF was greater on 80&40. Upon investigation I found that the output power cord to the router had been wedged in behind some AC Power 12/2 wires coming out of the panel. Just on spec I rerouted the cable away from the panel And the AC wires. To my great surprise upon testing with rig at 100w I discovered that on 160 m The line crash had stopped! With the amp on, the line would crash at about 300w. So on 160m some kind of common mode currents we're induced into the router power cable just by its proximity to the Household C wires! By the way on 80&40 the dramatic line crashes did not stop by the Change in location of the power cable. (OCF dipole used on these bands) To cut to the conclusion I proceeded to use all the 2" toroids (#31 material) I had on hand plus some #43 snap on beads to isolate as many AC power cords as possible in the shack....in particular The AC lInes to the rig and amp and the router power block. Guess I should have done this previously. The greatest impact was realized I when I used three toroids in a stack and would the CAT5 cable from the high speed line modular jack to the router with a many turns as possible. The line does not crash now at power levels of 500-600w on the three low bands. Common mode Currents were entering the router over its power cable an also the high speed line CAT5 cable. I need to place toroids on the drops feeding the TV's and the shack PC as well. I pass it this experience on in the event that it might help others encountering similar issues. I have read K9YC's excellent paper several times and have it to be a very valuable and practical Guide. 73 Frank VO1HP ____________________________________________________________________________ Limited optg time - self-imposed for domestic bliss! It seems my new IPTV wireless router (Brand: 2Wire, Inc. 3800HGV-B Gateway) does not like the ACOM 1010 running at full power. It would crash during every exchange causing loss of TV and internet access. Sometimes it might recover between Q's depending. Only after my XYL had retired for the evening on Sat could I really get into the contest. Further investigation needed to see if I can mitigate the problem.
