Peter Ellis VK1PE has found an interesting academic analysis of the
long-distance communication problem.

Peter VK1PE:
In a recent paper, "End-to-end interstellar communication system design for
power efficiency", David G. Messerschmitt of the University of California at
Berkeley proposes various solutions to the information rate vs. average power
trade-off. While this paper discusses at length the SETI problem, it is
probably a good read for those wanting to understand the place of channel
coding and other techniques. He discusses five power-efficient design
principles can asymptotically approach the fundamental limit on the
information rate, and in practice increase the power efficiency by three to
four orders of magnitude. The most important is to trade higher bandwidth for
lower average power.

Messerschmitt is no lightweight in communications: Fellow of the IEEE,
a Member of the National Academy of Engineering, and a recipient of the
IEEE Alexander Graham Bell Medal; Professor Emeritus and former Chair of
Electrical Engineering and Computer Sciences (EECS) at the University of
California at Berkeley.

His paper is quite readable, but at 237 pages, download it and read on a
screen. Find the reference link in the print version of this broadcast.

What use is an f-call?

Recently I was spending some time with a group of amateurs and we got the
urge to fix a local repeater.

In the past I'd seen things called cavities, but how they really worked or
how you might tune them seemed like a mystery. I can report that it's less of
a mystery today than it was last week. I'm yet to understand the full
implications, but I learnt something.

A repeater is a transmitter and a receiver working on two frequencies. The
repeater receiver listens for input on one frequency and transmits it on a
different frequency.

The frequencies are generally on the same band, a 600 KHz for 2m or 5 MHz for
70cm apart. When the transmitter is sending, some of the signal leaks back
into the receiver, making it less able to hear your signal.

A cavity acts like a filter. You have a gadget, that looks like a big
Pringles can, that filters out the transmit frequency and you connect that to
the receiver, in effect making the receiver less able to receive the transmit

The cavities come in a set that are inter-tuned. So, you make the filter as
deep as you can - making it deafer if you like - and each individual cavity
has an effect on the next.

With the right gear you can actually see what is happening and how changing a
bolt on the top of cavity affects the filter. Suffice to say that we spent
several hours playing and learning.

That is what amateur radio is like. You start with a small problem, hours
later, morning tea forgotten, you're still playing with connectors and
adjusting things.

UHF Radio microphones consultation

Following on from a recent story here on WIA National News about Radio Mikes
in Australia, New Zealand's Radio Spectrum Management is now inviting
submissions on their recently released discussion document
'UHF Radio microphones: Opportunities for future use'.

This discussion document presents future options for radio microphones using
the 518 - 806 MHz UHF frequency range.

This follows the New Zealand Government's recent announcement that it plans
to auction the 'digital dividend' radio spectrum in the 700 MHz band later
this year.


A discussion on a South African repeater about some tests on 472 kHz, asking
other radio amateurs to listen and give reports caused a frenzy and panic that
the activities could cause an aircraft to crash.

A listener to the conversation did not listen carefully and interpreted the
discussion as being about tests on 4720 kHz which is an aircraft band.

He warned the person on the repeater that they could cause an aircraft to crash.

The discussion went back and forth but the two parties did not realise that
they were talking about different frequencies. So a letter went off to ICASA
warning of the imminent danger. ICASA reacted and asked the SARL to investigate.

Of course SARL members are licensed to operate on 472 kHz on a secondary basis.
In the Table of frequency allocation 4720 kHz is shown as aeronautical mobile,
in some countries it is also used for broadcasting.

Any operation on 4720 kHz would not have caused an aircraft to crash but in any
case there was no operation by radio amateurs. The moral of the story is,
listen up and get the facts before you act and get everyone in a frenzy.


Word is a planned Cordell Expedition operation from Heard Island
has been postponed until January of 2015.

According to expedition organizer Robert
Schmieder, KK6EK and co-planner Rich Holoch,
KY6R, the primary reason for the delay was the
cost of using the preferred vessel, the Marion
Dufresne, to put the team on the island for the required time.

In note to the Ohio Penn DX Newsletter and
republished by the Southgate News, KK6EK and KY6R
say that despite extensive negotiations and
rescheduling of the cruise, it became clear that
the cost of using this vessel will exceed $1
million. Therefore the total cost for the
project would be about $1.5 million and that even
increasing the team size to 50 to partially cover
this cost was not enough. So the planners
reluctantly concluded that sponsorship at this level would be impossible.

KK6EK and KY6R say that they have therefore
decided to delay the expedition to the early 2015
date to allow more time to restructure the
project. It will also give them the ability to
locate a more suitable vessel and bring the cost
more in line with projected available resources.

According to Club Log, Heard Island is Number 7
on its DXCC Most Wanted List. The operations

Dorset England police are trying to locate what
they describe white VW transporter van with a
large amateur radio aerial on the roof that was
recently involved in a road rage incident.

Investigators allege that the van overtook a
silver Audi driven by a Portland man. Police
said the van driver and a passenger approached
the driver of the Audi and threatened him. They
then took the automobiles keys and threw them down the road.

No one was injured in the incident. An unidentified 35-year-old male was
subsequently arrested and released on bail pending further enquiries.

6m extension for Germany

German amateurs have had their 6m band extended until the end of the year.

The latest allocation is 50.03 to 51MHz and the bottom
30kHz ties up with where the new 6m Synced Beacons are
planned. They may use all types of transmission with a
bandwidth up to 12kHz but must not cause interference to
the primary user of the band, the military.

Meanwhile, the Israeli telecoms regulator has decided to
grant 5MHz temporary permission on an individual application basis only.

kit-building interests, their thoughts about the
many vintage Heathkits and their interest if any
in amateur radio. It also requests thoughts and
ideas about Heathkit while offering the
opportunity to sign up to join a mailing list.

The opening page instructions note that Customer
privacy is very important to them. As such that
they do not release personally-identifying
customer information outside our company as
explained in its Privacy Policy. As such, those
responding to the survey can choose which questions that they wish to answer.

Radio Sri Lanka stops using 7190 kHz

According to info received from Victor, 4S7VK, Hon. Secretary, Radio Society
of Sri Lanka, Friday, May 31, 2013 was the last day on which the
Sri Lanka Broadcasting Corporation used the amateur radio frequency 7190 kHz

7190 kHz has been used for decades by SLBC for broadcasts to South India in
various languages and at various times. The old timers may remember that at
one time Sri Lanka Broadcasting Corporation was the most powerful station in
Asia and very popular in India (no TV then!) and this 7190 kHz was their best
frequency for listeners in South India..

Water-based EMI RFI protective coating

MASTER Bond has released a new silver conductive, one part aqueous based
sodium silicate coating system formulated for use in EMI/RFI shielding

The MB600S is a coating which cures at room temperature in 24 to 48
hours, or in one to two hours at 80C.

It features high temperature resistance with a service temperature range
of -18C to 371C.

The energy emitted from various sources, including radios and
appliances, can interfere with other electronic devices.

Conductive coatings such as the MB600S are often applied to the housings
in order to protect the devices from these types of interferences. This
silver grey coloured system is used in a variety of aerospace and
electronic applications.

Tested according to IEEE 299, 2006 methods, MB600S was as effective as
the aluminium reference with a range of 95-105 dB, from 100 MHz to 2
GHz. Above 2 GHz, the shielding effectiveness of MB600S decreased to 80
dB and slightly below. Above 4 GHz, the effectiveness was 60-70 dB.

As the system is water based, it is relatively non-toxic and easy to
handle. It can be brushed or sprayed with the proper equipment. If
sprayed, the shielding effectiveness would be even greater than the
values given above.\ve-coating

participated in the International Museum Ships amateur radio event Saturday,
June 1

Watch the TV news report at




The United Kingdom's Guardian newspaper reports that Major Tim Peake has been
selected to fly on a five-month mission on the International Space Station in

Tim was chosen for astronaut training in 2009. Since then has been undergoing
mission preparation in a number of locations around the world including
Star City in Russia and the Johnson Space Centre in Houston Texas.

He had previously served in the army for 18 years primarily flying Apache
helicopters and has seen active service in Afghanistan.

Currently it does not appear that Tim is a licensed radio amateur, but
instruction in ham radio is still a part of Astronaut and Cosmonaut training.

Fox-1 FM transponder spacecraft has been assigned a November launch 2014.

Fox-1 is designed to operate in sunlight without batteries once the battery
system fails. This applies lessons learned from AO-51 and ARISSat-1

In case of IHU failure Fox-1 aims to continue to operate its FM repeater in a
basic, 'zombie sat' mode, so that the repeater remains on-the-air.

Fox-1 is designed as the immediate replacement for AO-51.

Its Mode B FM transponder will make it even easier to work with modest

A 1U CubeSat, Fox-1a will serve as a communications relay for radio amateurs
worldwide via the onboard FM repeater system. It will also carry an
experiment consisting of a 3-axis MEMs gyro developed by Penn State University.
The communications and experiment missions will run concurrently.

The uplink will be on 435.180 MHz for FM voice
and downlink on 145.980 MHz with FM voice and an optional sub audible
FSK digital carrier channel.

Fox-1a will employ passive magnetic stabilization.

For more information see

Fox-1a is planning to launch from Vandenburg in November 2014 on the NASA
ElanaXII mission with ARC1, BisonSat, Lightsail and R2S.

Amateur Radio is not just Cool it's Sub-Zero

Participants at a recent Scout Youth Council in Hampshire UK drew up a list
of Scouting activities ranked from Seriously Uncool to Sub-Zero.

The young people involved put amateur radio in the top rated Sub-Zero category
along with Quad Biking, Parachuting and Scuba Diving.

The four categories, Seriously Uncool, Uncool, Cool and Sub-Zero are based on
those used on the "Cool Wall" in the TV show 'Top Gear.'
