New Hams Episode 50 Digital Modes - Let’s Do it

Welcome to New Hams. Last time I spoke about getting into Digital Modes. I told you a bit about what’s around and what you may like to try, however I didn’t tell you how to go about it.

I try to keep this series non technical, and I’m about to give to a non technical treatment of a technical topic.

Setting aside newcomers to the computer world such as raspberry pie, arduino and specialised small kits for certain modes, I’ll be talking about connecting your Amateur Radio Transceiver to a computer, be it desktop or laptop.

Firstly, there must be some sort of interface. Yes, I know you can put speaker to microphone and vice versa, however if you want to do this thing properly, you’ll need to build or buy an interface between the computer and the radio.

You can buy an interface to suit your radio, and mostly these are quite good, and they seem to start at about $100, and go uphill from there, depending on how many bells and whistles you want.

Let’s talk about building an interface. What does one of these things do? We’ll make a list.

1. Takes sound from the computer’s sound card to an input of the radio. This may be the microphone input, or a data input
2. Takes sound from the radio to an input of the computer. This could be the microphone or line in connectors on the computer.
3. Operates the transmitter by triggering the push to talk. The push to talk is usually triggered by grounding a pin in the microphone socket or data portt.

A very simple audio interface from computer to radio would be a cable from the computer soundcard speaker socket to the microphone socket or data port of the radio. Similarly a cable from the external speaker of the radio, or the data port, to the microphone or line in port of the sound card will do the trick. And it may work, however radios tend to have a bit of RF wandering around, and this can travel down the cables and upset the computer. To fix this, you can use 1:1 isolating transformers. These are available from electronics suppliers or you could take one out of an old modem. You may or may not have to do something to match impedances, but you can usually get away with not doing that.

Now for the push to talk. If your radio has Computer Aided Transmission, better known as CAT, and you already have a serial or USB cable that does the trick, you’re done, if the CAT cable can operate the PTT. You merely have to tell the software which COM port the cable is using.

If your transmitter doesn’t allow the CAT to operate the PTT, you can build your own using a small handful of components. If your computer has a serial port, that’s great. Find or make a cable that plugs into it. Or purchase a USB to Serial adapter cable. I won’t bore you with how to build the PTT interface, other than to say it is triggered by the DTS and/or RTS signal on the serial port, depending on how you build it, and you utilise this signal to operate a transistor that grounds the PTT pin. There is a lot of information on the internet on how to build this small circuit. A simple version uses a transistor, a couple of diodes and a couple of resistors. I’ve seen designs where this circuit is contained within the DB9 Serial Port connector.

A simple interface like this will allow you to use any of the so called digital modes that utilise a computer’s soundcard. There’s a wealth of different modes out there for you to try. Let me know how you get on.

The Radio Amateur Society of Australia

The 23rd of November 2017 saw the launch of a new Australian organisation dedicated to the

growth of our hobbyAmateur Radio and representation directly to the Australian Government

Regulator, the Australian Communications and Media Authority – The Radio Amateur Society of Australia (RASA). In the short time since RASA’s launch, responses from around Australia have been very high.

RASA’s objectives are to:

- provide evidence based research and strategic direction for issues related to Amateur Radio to third parties involved in the administration, management and regulation of the hobby;

- promote Amateur Radio and its role in facilitating emerging communication technologies;

- educate and encourage the next generation of Radio Amateurs; and

- lobby the regulator to protect and enhance the privileges of Australian Radio Amateurs.

There are widespread concerns in the Australian amateur community over issues like allocation

of new bands, changes to licensing conditions and excessive noise levels on the HF bands.

RASA will listen to the needs and concerns of all amateurs and will make submissions to the

ACMA on Australian amateurs’ behalf.

RASA is a streamlined organisation focused on representation

We use using modern technology to manage our operations and communicate with members.

We intend to open lines of communication with as many Australian Radio Clubs as possible to

draw from their local knowledge and the experiences of their members. Clubs are the backbone

of Amateur Radio, and it is very important to provide a path for every Club to help define the future of our hobby.

To ensure we properly represent our members, we will be conducting on line surveys soon.

RASA also seeks to open lines of communication with our sister organisations in other

countries.

Please provide this information to the relevant officers in your organisation and

include us in any of your publicity material.

We have no direct affiliation with the Wireless Institute of Australia, although we do share many

of the same objectives and will co-operate in achieving positive outcomes for Australian radio

amateurs.

Our website and social media outlets provide more details and these can be found at http://vkradioamateurs.org or of course via vk6.net

Have a look and decide if you would like to join us.

This is Andrew VK6AS on behalf of The Radio Amateur Society of Australia.

Myths 07 Band plans are enforceable

When listening around the Ham bands, reading comments on social media and email reflectors, even talking face to face with Amateurs, I sometimes hear things said that are simply wrong. In this series I seek to address some of these myths.

In order to provide some form of order in the ham bands, most countries have adopted and adapted the International Amateru Radio Union’s suggested bandplans.

So there’s nothing mythical about the bandplans - they are adopted and implemented in most countries. What does enter into the realm of mythology is the interpretations of the band plans by some people.

Firstly, let’s be clear on bandplans. Bandplans are not law. They are not implemented by the Government or it regulator. Bandplans are adopted by the Amateur Radio peak body in the countries that use them.

You can’t be prosecuted for operating outside of a bandplan. You could, and possibly will, receive criticism from other amateurs for operating contrary to the band plans.

What makes us stick the bandplans in the most part is our sense of decency and fair play. That should be enough, and it uually is. Common courtesy is worth its weight in gold.

Another factor is stupidity. Let’s say you want to work CW, and you choose to do it on a frequency that’s earmarked for phone or some digital mode. Apart from annoying other people, you’re unlikely to find someone to respond to your call, because they are listening in the correct part of the band.

The bottom line is all about fair play and respect for other users.

In the news this week:

Peter VK3YE published a seven minute YouTube video called the Foundation Guide to Amateur Satellites with special focus on AO91, he has also posted part 2. The links are on vk6.net [https://youtu.be/astteV2umOg] [https://www.youtube.com/watch?v=XNB7Nc4HFYs] [http://n2yo.com]

Staying with the AO91 satellite, the AMSAT-BB mailing list points out that because it's relatively simple to operate this satellite, care should be taken to listen out for rare stations activating rare locations, rather than make a contact to your mate which you could do on the next pass. So, listen, listen and listen some more. There are several stations operating from rare grid-squares, specifically, wet-squares, think boat, so listen out.

If AO91 isn't you're thing, then listen out for AO73, FUNcube-1 which is now also doing the orbit thing.

If operating a satellite isn't to your liking, but you want to know how it works, then that too is covered. Check out the YouTube videos on the subject. [https://www.youtube.com/watch?v=A3ehDw5Yfhs] [https://www.youtube.com/watch?v=TjGAYvMyz4Q]

If you want to do some experimentation then the uBITX kit has just gone on sale. An SSB/CW radio that covers 3-30 MHz with a pre-built and tested board that "you just wire up to a few connectors and pots and put into a box". The radio manages 12 Watts and is perfect for portable operation. Until Christmas it's $109 US, afterwards it will be $129, including shipping. The link is on vk6.net [http://hfsignals.com/]

Andrew VK1AD and Andrew VK1DA, I'm not making that up, are discussing the idea of stimulating 23cm SOTA activations. If you'd like to join in the fun, perhaps you have a 23cm station that you'd like to use to talk to a summit, check out the SOTA mailing list for more detail and discussion.

If you're in VK3, Andrew VK1AD will be attempting to activate Federation Range on 1296.150 SSB sometime between 18 and 21 December, so turn on your radio and listen out.

VK6RIB, the Ham College Information Beacon which is situated on Wireless Hill at the WA VHF Group on a frequency of 145.575 MHz was off the air for a bit, but thanks to some sleuthing from Bob VK6KW the beacon is back on air. You'll find a two-hour repeating cycle with this news, the national WIA news, and information about amateur radio, clubs, the calendar and other information.

Paul VK5PAS has released the latest issue of Out and About in VK5. It's the second last issue ever after three years, so if you have a story for the final one, get in touch with Paul. [http://www.vk5pas.com/out-and-about-in-vk5.html]

During the week Peter VK3TKK and Peter VK3PF managed 17 VKFF activations on a single day between them. We look forward to receiving their travel and activation reports for the news.

If you have a suggestion for an additional park to add to the list here in VK, then contact Paul VK5PAS with your suggestion. Bear in mind that he can only add 500 per year for all of VK, so be selective.

If you have a story that you'd like to share, get in touch. The address is newswest@vk6.net.

VK6 Notes for Steve
