---===( NEXT MEETING: THURSDAY 13 SEPTEMBER 2018 AT 18:00 )===---
It looks likely that this will be the last hilltop get-together, at
least for 2018. As usual, we'll meet by the Royal Observatory in
Greenwich, nearish the clock. Everyone is welcome - look for bikes,
antennas, that sort of thing. If you get lost, someone should be
listening out on 433.500MHz. We even have an object on APRS -
https://aprs.fi/info/a/HACKRS - look for HACKRS. Being September, the
meeting will likely be a bit darker and damper than usual. It might even
rain, so check the wiki page (URL in the header) to check whether we've
decided to go to a pub instead.
=> Note the earlier time of 18:00; this is to allow for the fact that <=
=> the van to throw us out of the park appears at 20:00 in September! <=
An amateur-to-be, George, came along to our last meeting and we told him
a bit about what radio is all about. Others stopped to ask what it is
we're doing or just to let us know that they are into radio too. On the
table, Mat and Sam were testing out a couple of antennas for packet, one
on a bike-mounted pole and one on a cord slung over a nearby tree.
---===( HACKSPACE NEWS )===---
The hackspace is returning, thanks to a band of helpers. Regular open
evenings have started again on Tuesdays at 7pm, the network is going in,
and work areas are being installed. The more members who can help, the
faster the space will be open. Get in touch if you can help!
---===( TWO MEMBERS LEVEL UP )===---
Mat 2E0TPS is now M0XPX and Michael 2E0KRV is now M0ISR! In other words,
both have achieved full licence status. Congratulations to both of them!
---===( NETWORK MAP )===---
The network map shows the users interested in connecting via packet and
the success with which they have reported establishing connections. The
maps remain unchanged from last month, though there was a flurry of
interest in packet on the mailing list.

---===( LINK OF THE MONTH )===---
http://aprs.mountainlake.k12.mn.us/ - Several members have reported
hearing calls or seeing APRS packets from a long way away, even across
the Channel, on their radios while hillwalking lately. This is likely
due to tropospheric ducting, the result of climatic conditions causing
temperature inversions, which in turn cause a higher refractive index in
the atmosphere, 'bending' the signal. Using data from APRS-IS (in other
words, packet stations), this site presents a world map showing radio
propagation from stations operating near 144MHz from the last hour. It
might surprise you how often and how far propagation is reported at this
time of year.
