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
