ISS astronaut contacted by Gloucestershire radio ham in garden shed

Radio ham Adrian Lane was able to send his "73" (ham lingo for "best regards") to an American astronaut as the International Space Station passed over Gloucestershire.
The amateur operator told The Telegraph of his communication with the International Space Station from his garden shed in the small market town of Coleford.
Lane will have spoken to either Scott Kelly [PDF], or Kjell Lindgren [PDF], who are the only Americans currently aboard the ISS as part of Expedition 44.
Lane, 52, reportedly spent weeks preparing to contact the ISS after he was informed that the station would be passing over his home. The former lorry driver plotted the approximate path of the ISS using Michael Lodge-Paolini's ISSTracker.
He established a four-minute window during which the station would be contactable as it orbited the planet at 18,500mph, or 0.2759 per cent of the maximum velocity of a sheep in a vacuum.
Lane waited to broadcast his call-sign as the space farmers passed 200 miles overhead. Then, "to his astonishment, an American astronaut answered back to 'welcome him aboard'".
The pair managed to communicate for roughly 50 seconds before losing contact.
Father-of-two Lane told The Telegraph that "it was a mundane conversation" which still "blew his mind", despite Lane asking what it was like in space and receiving the laconic reply: "Very dark."
"I said to them how wonderful Earth must look from up there. They said 'Oh Adrian, it's amazing, you can't imagine what it looks like from up here'," Lane gushed.
"He said it was very dark, but when you look down at Earth it is full of colour. I basically asked who he was and how things were in space that day. It was such a rush. I was buzzing. It's not every day you get to talk to some guy out in space," said Lane.
Expedition 44 [PDF] will feature the first humans to harvest and eat crops grown off-world, which NASA describes as "another necessary advance for astronauts travelling on deep space missions".
Astronauts will be allowed to eat half of the second crop of lettuce in the Veggie investigation, freezing the other half for a return to Earth, where scientists will analyse the plants and compare them to a control set grown at NASA's Kennedy Space Center.
During downtime on weekends, ISS crew members have been known to make unscheduled amateur radio contacts with us Earth-dwelling apes, as we dribble our meager terrestrial comestibles down our fronts.
The Telegraph reports that Lane "spends most of his time using permitted frequencies to talk to fellow enthusiasts around the world", much to the chagrin of his wife, Deilwen.
"She hates it with a passion," he said. "We've had so many rows over it. Even the kids know where to find me. Where's Dad? Oh, he's in the shed again."
Ten British schools have been shortlisted to make contact with Her Majesty's astronaut Tim Peake, again using amateur radio, after he boards the station on 15 December for Expeditions 46 and 47

Rogue US Navy satellite causing QRM across Europe

A satellite launched by the US military has gone rogue and is causing interference to radio hams across Europe.
The US Navy’s PCSat NO-44, which is only supposed to transmit over the US, is now drowning out European amateurs and the USN doesn’t know what to do about it.
Licensed as an amateur satellite in the Amateur Satellite Service, PCSat was launched 30 September 2001 from the Kodiak Launch Complex on Kodiak Island, Alaska aboard Athena I.
It was designed to be a worldwide position, status reporting and message communications satellite for remote travellers. The satellite is on a tight polar orbit and passes over Europe every hour or so.
It uses the APRS (Automatic Position Reporting System) protocol to permit hundreds of users per pass to access the satellite. To demonstrate this concept, PCSat augments the existing worldwide terrestrial amateur radio APRS tracking system by providing links from the 90 per cent of the Earth's surface not covered by the terrestrial network, so when it passes over it drowns out other users of the frequency.
The spectrum it interferes with is around 150MHz, and generally used by radio amateurs for meteor scatter, sending short text messages over distances of up to 2,000km by bouncing them off the ionisation caused when a meteorite breaks up in the atmosphere. The last thing a radio ham wants is to wait for a meteor shower to send a message and then have it drowned out by a passing satellite.
Now redundant, PCSat NO-44 should be dead, but isn't. This is because it is designed to use more power than it has on board – a negative power budget – and then reboot when its solar cells generate enough power to wake it up. Robert Bruninga of the US Naval Academy, posted to a Usenet group to explain the problem:
PCSAT (now 14 years old) had a backup fail-safe beacon on 144.39 [MHz] that would activate after any unknown spacecraft reset to give us a backup comm link in case the primary 145.825 channel died.
Being on the North American APRS frequency with hundreds of IGates there would always be at least one that would hear this "emergency call home" from PCSAT even though the channel is generally saturated. And it worked.
The problem is, that now PCSAT resets on every orbit due to negative power budget and so, on every orbit that beacon comes back on. Even if we did get a command up to reset it, that setting would last only 15 minutes to the next eclipse.
We learned our lesson! That was our FIRST amateur satellite and we sure learned NOT to use a "connected-packet-command link" that needs ACKS and Retries and logon passwords just to LOGON before you can even send a SHUTUP command.
All our satellites since operate without the multiple Send, Connect, ACK, retry, ACK, Command, ACK overhead ... just to get one command understood. Now, only the receiver on the spacecraft has to be functional to command it to silence in a single packet. But too late for PCSAT.
We are sorry that we have no good answers. But we hope we can mitigate this instance of "friendly fire" collateral damage so that we don't cause an overall black-eye to amateur radio overall friendly operations?
An extra-terrestrial radio source is outside Ofcom’s jurisdiction, but the US Navy may be in breach of International Telecommunications Union regulations, which stipulate that radio transmitters remain under control.
In time, the solar cells will stop holding enough charge, and the orbit of NO-44 will decay, with the satellite burning up, but this is many years, perhaps decades away. Until then, the frequency remains very difficult to use.

MD-380 DMR Radio

I bought a Tytera MD-380 DMR radio last week and so far I am very impressed with it.  It came with a programming cable and I found a copy of the programming software to download.  I must admit that it took me a while to get my head around DMR however I found a video on Youtube which went through programming the CS-700 and the software looked almost identical to what I was using.  Success, I figured out target groups and colour codes and got a couple of frequencies programmed in to it to listen to, my local Shopwatch and the parking wardens in Manchester.  I found SDR# and DSD plus on the PC to be invaluable in determining which information needed to be programmed in.



The range on digital appears to be very good, the transmissions from 20 miles away are crystal clear.  You can scan frequencies via a selected scan list which is perfect to monitor a number of services.  The radio is compact and the colour display is very clear.  It did come preprogrammed with all the HAM DMR-Marc frequencies but I've not received anything on any of these yet, not really sure how popular they are and whether I'm in range of the repeaters.  The next thing I'm interested in is DPMR, I'm wondering if I'll get greater range than the analogue PMR service.

I would certainly recommend one of these radios but would strongly suggest that you make sure you get the programming cable with it as although you can program the radio via the front screen I can't see any way of inputting groups and colour codes.

Vulcan XH558

The Vulcan will be flying around the UK tomorrow - 27th June 2015.  It has not got its own assigned frequency so will use a common CAA show frequency or the Airfield A/G frequency when displaying at a show.
XH558 is a private civilian aircraft and nothing to currently do with the RAF but has been known to use RAF Linton On Ouse UHF approach frequency in the past when in that area.  It may use the standard airfield tower and approach frequencies.  Route map is below.

UK DMR (MOTOTRBO) AMATEUR REPEATERS LIST

There are a lot of new DMR repeaters popping up which is good news to many, D-Star has been too expensive for most due to Icom running the show and their gear being expensive which has led to a kind of exclusive club as far as D-Star goes. DMR and Mototrbo radios are growing in popularity and DMR is an open standard, not only for business users but also for private users including hams.
Below is a list of current DMR repeaters in the UK.

Brit plods' post-TETRA radio omnishambles comes home to roost

From The Register

The £1.2bn emergency services contract which The Register flagged up as an omnishambles six months ago has now, as predicted, collapsed.
After a year-long bidding process the government had whittled the tenders down to two companies: EE and O2. Now O2 has pulled out as a result of Telefonica selling the network to Three’s parent Hutchison Whampoa.
The network is supposed to start replacing the creaking Airwave TETRA radio system used by the blue light services next April.
There are huge question marks over the suitability of 4G for this with the necessary standards for device-to-device communication and control of groups still in the planning stages, and even bigger issues over equipping emergency services with mobes that rely on 4G for push-to-talk communications when 4G coverage is so patchy.
O2 released the following statement:
    The potential restructuring of the UK telecoms market as a result of current M&A activity affecting several players in the industry raises questions about spectrum (both current holdings and timings of access to future spectrum), network sharing arrangements, and specifically our position in the proposed potential acquisition of O2 in the UK by Hutchison Whampoa.
    We are therefore unable at this time to provide the detail and commitments required to continue into the next stage of the bidding process put forward by Government.
    We have taken the decision to notify the Authority that we will immediately withdraw from the bidding process for ESN so that the Government can consider next steps before the award stage.
This leaves the government the choice between scrapping the whole procurement process and, as we predicted, extending the existing TETRA contract ... or pursing a bidding process with only one bidder.
Since that bidder is being bought by BT, it is unlikely to be the most important thing on EE’s current agenda - and while the contract may be worth hundreds of millions of pounds, that’s only a small part of the company’s turnover.
The Home Office told The Register that if the BTEE offer does not meet the requirements and budget of the emergency services, it will not pursue the process.
O2's decision to withdraw, for commercial reasons, from the procurement process to provide the UK with a new emergency services communications network is disappointing," said Mike Penning, Minister for Policing, Crime, Criminal Justice and Victims.
However, the process to establish a more effective, flexible and affordable network for the UK's police, fire and ambulance services will continue.
"Seven other bidders remain in the running for the main contracts and we look forward to receiving their best and final offers during in June. We hope to sign contracts later this year," Penning added.
Those seven bidders are spread across three lots. Atkins, KBR, Lockheed Martin and Mott MacDonald are competing to be the delivery partners, with HP and Motorola going head-to-head for user services. It’s now a one-horse race for the mobile services.
In February, James Brokenshire, then minister for security and immigration, said the Mobile Services lot had “produced some impressive technical bids combined with the prospect of significant cost savings for the taxpayer”.
If the emergency services are going to move from TETRA to 4G, coverage will need to be improved from being among the worst in Europe. ®

Airwaves and Callsign 2015 - Book Review



Airwave and Callsign 2015 from Photavia Press describes itself as "The complete UK civil and military HF / VHF / UHF aviation frequency and callsign directory" and I can't really argue with that.

Starting off on the inside cover you get a list of all the Airwave and Callsign abbreviations such as MATZ (Military Air Traffic Zone) and SAR (Search and Rescue), a handy list that is easy to get to.  Once you get into the book itself you are presented with all the UK and European Civil and Military area radar frequencies.  Military discrete frequencies are next, followed by air surveillance, tactical and airfield frequencies - the latter is a very comprehensive list covering a number of pages.  VHF/UK frequencies for the UK and NATO military traffic fill a large section followed by world air frequencies.  HF listeners are covered by a large list of HF frequencies along with all the locations indicators and squawk codes in use today.  A selection of maps outline the many air routes and sectors in the UK and we even get a map showing all the UK/VHF transmitter sites. We are now about half way through the book and the rest of the publication has every single callsign, both military and civilian, that you would ever need to know.

All the information is well laid out and easy to both find and read, there is no table of contents though so you do have to flick through the book to find the section you need.    The information itself in the book is very extensive.  According to the publisher 70% of the military callsigns have been added or reconfirmed in the last 2 years and 23% were added in early 2015.  For the 2015 publication an extensive check has been made of the civil callsigns with a number being deleted or added.

The book is spiral bound with 184 pages and measure 21x15 cm.  It's a nice size to easily fit into your radio bag.  I was very impressed with this book because a large amount of this information was new to me.  I do have a number  of radio, scanning and aircraft books which do not even begin to approach the vast amount of content present here.  I would say that the military airband listener would appreciate this book more that most but it's still an important resource for the civil airband enthusiast.  Overall I have no hesitation in recommending Airwaves and Callsign 2015 for all airband listeners.

The bad news is that after being published for 42 years a decision has yet to be made whether publication will continue in 2016, I'm keeping my fingers crossed that it does.

Airwaves and Callsign 2015 is published by Photavia Press and is priced at £20 (plus £2 postage).  It can be ordered from their Order Page.

Scanner Collection



Here is my collection of scanners and radios.  I did possess a couple of scanners many years ago when it was still possible to listen in on the police transmissions and the old analogue mobile phones. A couple of years ago I decided to get back into the hobby and my collection of radios has slowly grown.  All of the scanners (apart from the handhelds) are connected to internal antennas placed in an upstairs window, unfortunately external antennas are not an option at the moment.

Base scanner is a Uniden UBC355CLT.  This was the first scanner I purchased after getting interested in scanning again.  It's a nice compact radio, the only thing I wish it had was alpha tagging as it only;y displays the frequency when received a transmission and I do find it a bit complicated to program - no facility to program it via the PC.

I have two handheld scanners, a Uniden USC230 and a Uniden UBC125XLT.  Both have been fitted with Watson antennas to replace the supplied rubber ducks and they work very well in the house.  Programming for the pair is performed using one of my computers with the Butel software, which also allows me to save all the programmed frequencies to an external file.  Also of use is a control program for the UBC125XLT called Scan125.  This is a free piece of software which allows me to operate the scanner from the PC, well worth downloading.  Why two handheld scanners?  The USC230 was my original choice however when attending the Rhyl Airshow I was a bit disappointed that I couldn't receive the Red Arrow transmissions nor the Valley airbase while at the caravan in Prestatyn since it does not cover the military airband.  The UBC125XLT rectified this as it does receive the military aircraft frequencies (I even managed to pick up Valley one weekend from here in Northwich).

Next up is a collection of dual band radios from Hong Kong suppliers.  A couple of Baofengs and a TYT.  Radios such as these are available on Ebay or Amazon for a very lost cost. These allow me to receive and transmit on the PMR channels and are also great for receiving marine and Search and Rescue (SAR) traffic.  Once again, all have had their standard antennas replaced with third party products.  The Baofengs are easily programmed from a PC using Chirp software though the TYT looks for an RS232 connection and refuses to connect via any USB connection - a pain having to program this one manually!

A couple of CB radios are part of the collection.  An Intek H-520 Plus, Probably the best handheld on the market.  This can be connected to an external antenna, if required.  The CRT S-Mini is designed to be operated in the vehicle, however a cigarette power adapter allows me to use it indoors.

The Target Communications receiver is a HF radio.  It covers 30kHz to 30MHz which I believe is a good range.  A shortwave wire antenna around the room completes the set-up.



Finally I have a number of  RTL chip based SDR dongles.  These are Software Defined Radio dongles which can be connected to and controlled by a PC.  You an visually browse a wide spectrum, complete with waterfall display and are an inexpensive way to get into radio listening.  Using the SDR# and DSD Plus software it is also possible to decode digital transmissions such as DMR.  I listen to the Northwich Shopwatch transmissions as even though this is digital it is not encrypted.  At the moment I'm experimenting with SDR on a Windows tablet, this would make a great portable solution for receiving digital broadcasts.

I am looking at getting a DMR digital handheld radio in the near future.  These are only just coming on to the market at an affordable price (from China, obviously).
