November 2019
Editorial
Welcome
Radio Trends and
Technologies
ello and welcome to the
November 2019 issue of
RadioUser.
It was great to
see so many of you at the
National Hamfest. I have en-
joyed talking to you and getting to know
so many radio groups and associations
I was not aware of. I have incorporated
some of the ‘flavours’ of this year’s big
event into this issue, as you will see.
Autumn is here, the nights are getting
longer, DXers come out of their summer
torpor, and radios are being dusted off.
To facilitate your listening pleasure and
help you look in the right places, I have
added some additional reviews of fre-
quency lists, listening resources and sea-
sonal guidebooks to this issue. In this is-
sue, you will find, for example, reviews of
new versions of a well-known
NDB DXing
Guide,
and of the BDXC’s updated list of
Radio Stations in the UK and Ireland.
Ireland is also the topic of our main
book review this month, and a very inter-
esting title this is.
There are two features with a predom-
inantly historical background this month.
While Tony Smith delves into the history
of the very early broadcast hobbyists and
experimenters, I am speculating on how
a new biography of Nikola Tesla, which
has just been published to great acclaim,
might, perhaps, alter our perceptions of
this pioneering inventor.
Radio history will also feature a little
more prominently from now on, as Scott
Caldwell’s column will be coming out on
a monthly basis very soon.
Moreover – and in the context of the
current climate debates – Keith Hamer
and Garry Smith begin a two-part explo-
ration of how climate and weather (the
climate at your location) affect us as ra-
dio enthusiasts, in terms of propagation,
monitoring, data interpretation, forecast-
ing, and DXpeditions.
Regarding the latter, watch out for a
new
RadioUser
series on mobile DXing,
from January 2020.
Elsewhere in this issue, you will learn
about how airport radar is ‘going cloud’,

Reception

propagation and weather forecasting.

Review: Radio Stations in the
UK and Ireland
To round off this issue, the editor offers his views
on this indispensable new resource by the British DX
Club (BDXC).

Rallies & Events
Our most up-to-date events list of radio rallies, hobby
meetings and connected activities.
how you can listen to transatlantic air-
craft, what exactly happens in the ma-
rine bands these days, and whether
or not network radio can be beneficial
to your health.
There are also hints and tips on
Inmarsat Satellite reception with a dog
bowl and tiny aerial, and on the pro-
ceedings of the
European DX Council
Conference,
which took place in beautiful
Andorra this year.
Watch out for a feature on Radio
Andorra in the not-too-distant-future,
here in
RadioUser.
There is somewhat of a focus on tech-
nology and equipment this time around,
as you will see from the content of many
of our columns; for instance, you can
discover digital radio apps, new tech-
nology podcasts, and the intricacies
of quad aerials.
Last but certainly not least, turn to
page 27 to be in with a chance to win a
fabulous new network radio.
Read on and don’t forget to get in touch
with me, and to respond to our call for
new writing talent. We are still looking for
future team members of the
RadioUser
group of authors. I’ll be in touch with ev-
eryone who has written in so far.
Enjoy this issue of
RadioUser.
