Re: Topband: Speaking of noises...

[Mike Waters]

Sounds like our former secretary's cell phone. When she placed it next to
her computer speakers, we could hear it faintly. Took us a long time to
figure that one out!

I believe this may be some sort of ionospheric sounder but I've heard this
for decades, including when I was in Colorado.  Hopefully someone knows
what's generating this.

Re: Topband: Wednesday 160m DX Activity Night

[W0MU Mike Fatchett]

Tuesday I worked an EA7 on FT8.
Wednesday activity FT8 wise was down quite a bit.

To my surprise,  Fedor’s signal was readable here in WV, and he was easily 
worked.  Of all nights to get him, I did not think it would be last night.

Goes to show, you can take nothing for granted on 160M.   I almost pulled the 
plug due to the poor condx, and would have missed a new one if we would have 
done that.

Conditions have been rather poor the last few evenings . . . or is it just
lack of activity?!

Well, I'll be on this tonight from around 2330Z, so hopefully lots of others
will be too

So we'll find out !

Topband: LF-MF Antenna Notes

[Joel Harrison]

Rudy, N6LF, has prepared an excellent set of LF-MF notes on his website
that is very interesting and informative read, even if you don't
understand some of it (or most of it in my case!). As always, his work is
first class.

http://www.antennasbyn6lf.com/2017/02/lf-mf-antenna-notes.html

Also for those of you who will be attending Dayton, I understand that
Eric, NO3M, will be presenting some of his excellent work and experience
with RX antennas on these bands as well at the Antenna Forum.

All good stuff!!

Re: Topband: Wednesday 160m DX Activity Night

[VK3HJ]

You will have to excuse me, as 2330z is 1030l and the sun will have been up 
for 3.5 hours.


I will be trying around my sunrise from now until the end of summer, around 
2000z for Europe, except on contest weekends.

Roger,

For me the change was on Saturday.  I thought conditions were much
better on Friday night / Saturday morning, then they were Saturday night
Sunday morning.  Only speaking for my station, since then signals from
EU have not been as strong as they were on Friday night / Saturday morning.

Yesterday evening they were S9 on my poor 6m high INV-L. The 1810-1820
