In many ways, VHF operators in the EU lead the United States in their
activity on the VHF band. If you've ever read a copy of the
German/English publication, DUBUS magazine, you quickly get a sense of
just how much is being done across the pond. Recent advances that I can
think of include the low-noise LFA antenna, and the MSRX software
decoder for WSJT modes.
Here's another development that I think holds promise for US operators
too. It allows much more active monitoring of E-Skip DX when you're away
from the rig. Download it, and start using it today. E-Skip season is
coming soon. Hope to see you on 2 Meters!
The Android app "EsSense", which was launched in December, has been
received well by the VHF community. Several hundreds of European operators
have meanwhile downloaded the app; they are using it to literally "stay
tuned" at all times and greatly enhance their DX power. Many thanks to all
users for their useful feedback - this was a great help to fix bugs and
further improve the app.
Now that EsSense has reached a mature level it's time to expand the
functionality to other regions: The latest version (0.10) now also
supports North and South America, Middle East and Africa! (East-Asia,
Oceania, Australia coming soon).
EsSense can be downloaded for free from the Google Play store at:
https://play.google.com/store/apps/details?id=net.gooddx.essense
Good DX!

If anyone has some audio recordings of AO-40 telemetry (regular or FEC)
(.WAV or .AIFF format), then please could you zip them and send them to me.
I need them for some experiments.

I tried downloading the new AggieSat4 .doc files from their Dropbox at
https://www.dropbox.com/sh/v8razh1evcabt7a/jrGSjbOJb4
Was unable to read either until I changed the file type from .doc to .pdf
Looks like they plan to runa high speed 153.6 kbps downlink in 436/7 MHz
with 5 watts output using emission designation 406KF7DBN. SpaceX launch is
currently slated for September.

Paul:
I have a recording or two. I created a video using the files - see link
below. Let me know if you're interested.
