<DIV>Yeah, and certainly once or twice a year for 2 hours is not so bad...its
actually pretty amazing how far the signal got out...I doubt they are pushing
more than half a watt either. Maybe a lot less...</DIV>

<DIV>The interfering transmission on 144.440 MHz was coming from the GreenCube
6 balloon payload which was in the air over Mt. Washington from 10:30-12:30
this morning. The flight is over, and there will be no more
transmissions on that frequency today. Todd and Kristina (cc'ed) are the lead
investigators on the payload, and should be contacted with questions about the
transmissions.</DIV>

<DIV>That is really strange. Our repeater operates on 444.950, and
that's the only source of transmission I am aware of. We haven't
operated packet for years. I will forward your message to some

anything out.</DIV>

<DIV>To whomever it may concern,<BR><BR></DIV>There are strong packet
transmissions being sent on 144.440 that are identified by the W1ET call
sign. They are causing a bit of a disturbance to a large group of
operators on 144.450. I imagine this is unintended, as the last
time something like this happened it turned out the transmissions were
intended for a frequency 600 khz higher, but the operator had
inadvertently pushed the "shift button".<BR></DIV>Could you please check
your station and see if it is responsible?<BR><BR></DIV>

<DIV> </DIV></DIV>It has been suggested that the actual
transmission bothering us may be a "retransmission" of your signal by an
"unknown station", however the only call sign in the transmission is
yours.<BR></DIV>The signal I am receiving is quite strong (40-60 over
s-9 to a phased pair of 10 elements) in the direction of roughly 20
degrees from my location in Newtown, CT, and appears to be horizontally
polarized.<BR><BR></DIV>Thank you for any assistance you can provide us
in this matter.<BR><BR></DIV>Bob N1UJS<BR>
