Hi Jim,
Bad news for me. If I transmit long enough, and on enough frequencies
between 1.800 and 1.835 Mhz I can get the ADSL2 modem to lock up. I even
added 14 turn chokes on the incoming data line, and out going phone line on
the modem. Each device I added helped, but not totally bullet proof, and I
am now out of bullets.
