Hi Eric,<br>
<br>
It is possible that Yorke and Max have a packet transmitter on their
research balloons. If so, they need to check frequencies beforehand
AND have to contact you as the trustee of W1ET or me as the officer
of record before using the callsign.<br>
<br>
Yorke, Max?<br>

<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

get back to you if I find anything out.</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>Here is a copy of the
transmission:<br>

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>
