Fortunately I have a Wi-Max service that is immune from RFI but I frequently use a DSL service for remote control with guest ops during contests. The DSL is more reliable in so much is I get 1.5 Mbps up and down all the time and every time. (The Wi-Max at times gives me CW hick-ups and although it works with Icom's RS-BA1 remote this does not compare with reliability and flawless remote paddle CW using Remote Rig and a Kenwood TS-2000. Remote ops prefer being able to have a real rig head in front of them and use a local paddle as well.)
My problem is that when I try to operate on 160 the DSL crashes. I have tried many Type 31 3 inch ferrite rings with 20 turns on both the phone line and the Cat 5 cable from the Zhone modem but even at 200 watts the DSL looses sync. I even have disconnected all phones and faxes but to no avail. I'm sure this problem has been around this site for some time but I would like any information on what i should try. My telephone line enters the shack about 70 feet from a cage fed 85 foot tower and the nearby 80 meter 1/4 wave vertical does not cause problems, only the 160 meter antenna, and with relatively low power. I don't hear any audible IX on the telephone while transmitting which leads me to believe my problem is not a simple one to solve. Any suggestions on what to try like using CAt 5 cable to the pole instead of normal drop wire, RF Chokes, K-Y or K-Com filters, what works best with a DSL with 160 meter IX problems. Please let me know. Thanks, Herb Schoenbohm, KV4FZ _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
