Day 1: Clear blue skies & soaring temperatures outside but I managed several hours on 20m with brief excursions to 15 and 40m. I managed to work 2 all time new ones in the form of A62A (UAE) and VE3DZ/VP9 (Bermuda) and the overall QSO/country count for my modest first day effort was 91 contacts in 43 different countries.

Day 2: Mindful of being out for much of the day it was an early start for day 2 of my contest effort. They say that the early bird catches the worm and it was oh so true on this occasion when I snagged KL7RA in Alaska for another all time new one at 06:33 UTC followed by KH6MB in Hawaii a few minutes later.

I managed about 4 hours in total, on and off through the day, finally shutting down around 21:30 UTC mindful of work the next morning. In total over the two days I logged 122 contacts in 52 countries with 3 all time new ones and 1 new US state (Idaho), not bad for a seriously compromised antenna and no more than 75 watts output.

The 3 must-have software tools in my shack

As an amateur radio operator, I've spent countless hours tinkering with various software tools to enhance my operating experience. Over the years, I've come to rely on three essential types of software that I believe every ham should have in their digital toolbox. Let me share my personal favorites and experiences with each.

1. Logging software: N3FJP's Amateur Contact Log

Since 2005, N3FJP's Amateur Contact Log has been my go-to logging software. It's user-friendly, feature-rich, and has stood the test of time. What I love most about it is its ability to handle both casual contacts and contest logging with equal ease. The interface is intuitive, making it simple to enter QSO details quickly, which is crucial during fast-paced contest operations.

The software's integration with various transceivers for frequency and mode tracking is a huge time-saver. Plus, its ability to generate reports and statistics has helped me track my progress towards awards like DXCC and WAS. While there are newer options on the market, N3FJP's reliability and regular updates have kept me a loyal user for nearly two decades. Thanks Scott!

2. Digital modes: A suite of specialised tools

When it comes to digital modes, I've found that no single software can do it all. My journey started with Digipan, which served me well for basic PSK31 operations. However, as I delved deeper into the world of digital modes, I expanded my toolkit.

Currently, I use a combination of:

• Airlink Express for PSK31 and AFSK RTTY
• MMTTY for FSK RTTY
• JTDX for FT8

Airlink Express has become my primary software for PSK31 and AFSK RTTY. Its clean interface and robust decoding capabilities making it a joy to use.

MMTTY is my go-to for FSK RTTY. Its superior decoding algorithms have helped me pull out signals from the noise that other software missed. The ability to fine-tune various parameters gives me the edge I need during tough band conditions.

For FT8, JTDX has been a game-changer. Its efficient use of system resources and excellent weak signal performance have allowed me to make contacts I never thought possible. The integration with logging software and online resources like PSK Reporter are also really worthwhile features.

3. Web Browser: The Swiss army knife of software

Last but certainly not least, my web browser is an indispensable tool in my shack. It's my gateway to a wealth of resources that enhance my operating experience:

• Propagation prediction tools like VOACAP and ionospheric maps
• Real-time band condition reports from sites like DX Summit
• Contest calendars to plan my operating schedule
• Online QRZ lookups for quick operator information
• Access to propagation visualisation tools like PSK Reporter and the Reverse Beacon Network
• Ham radio forums for troubleshooting and community discussions

The beauty of using a web browser is that it's always up-to-date and provides access to the latest information and tools without the need for constant software updates.

4. What, no rig control software?

No...not for me. Well not yet at least. I've tried various rig control software over the years but never really taken to them because I very much enjoy the hands-on tactile approach of actually touching and using the radio. Slowly tuning across the bands listening deep into the noise for those distant stations and then using the rig's controls to dig out the signals with filters and noise reduction. I just get a far greater sense of achievement doing it that way.

In conclusion, while the hardware in our shacks often gets the spotlight, these software tools are the unsung heroes that make modern amateur radio operation efficient, enjoyable, and endlessly fascinating. Whether you're a seasoned operator or just starting out, I highly recommend exploring the myriad different software offerings to find those which best suit your operating habits. 

7 Things I like about the Xiegu G90 (and 2 things I don’t)

The Xiegu G90 has gained quite a following in the world of portable ham radios, and for good reason. After using it for a while, I’ve found there are plenty of reasons to love this radio but it’s not without a few quirks. Here’s a breakdown of seven things I like, and two things I don’t.

7 Things I like about the Xiegu G90

1. Form factor – It’s small

The compact design is one of the first things that caught my eye. At just over 2 pounds and small enough to easily fit in a backpack, it’s perfect for portable setups like POTA (Parks on the Air) or SOTA (Summits on the Air). Its diminutive size makes it easy to carry around and operate anywhere.

The Xiegu G90

2. Build quality

Despite its small size, the G90 is solidly built. The sturdy construction gives me confidence that it can withstand a bit of rough handling during portable operations. The buttons and knobs feel durable, and the overall design suggests it’s built to last. It really is a lovely little radio.

3. Built-in internal antenna tuner

One of the standout features of the G90 is its wide-range, fast antenna tuner. Having this built-in means I can quickly match a variety of antennas without needing an external tuner. The fact that it works so efficiently is a huge plus, especially when experimenting with different antenna setups.

4. Full feature set in a tiny package

The G90 packs a ton of features typically found in larger, more expensive radios. From CW and SSB to digital modes like FT8, this little rig can do it all. It even has a spectrum display, which is quite handy. For such a compact radio, it doesn’t sacrifice functionality.

5. 20W output power

Unlike many portable radios that max out at 5 or 10 watts, the G90 offers 20 watts of output power. This extra power makes a noticeable difference when trying to make contacts, especially in less-than-ideal propagation conditions. It gives me an edge without needing to lug around a larger radio.

6. Price

The Xiegu G90 is affordable compared to many HF transceivers with similar features. For someone like me, who enjoys portable ops but doesn’t want to spend a fortune, the G90 strikes a great balance between cost and performance.

7. The YouTube community

One of the unexpected benefits of owning the G90 is the wealth of “how-to” videos and reviews on YouTube. The community of operators sharing tips, tutorials, and mods is incredibly helpful, especially for someone just getting to know the radio.

Things I don’t like about the Xiegu G90

1. Small tuning knob

As much as I like the form factor, the small tuning knob fitted as standard can be a bit frustrating. For someone with larger hands, it can feel a bit cramped, and precise tuning requires a bit more effort than I’d like. A larger or smoother tuning mechanism would have been a welcome improvement.

2. It gets hot in a hurry

This radio runs hot, especially during extended operations. While it hasn’t caused any serious issues for me yet, I do worry about the long-term impact on the radio’s components. Some external cooling might be necessary for longer sessions to keep it from overheating.

While the Xiegu G90 is far from perfect, the positives far outweigh the negatives. It’s an excellent choice for hams like me who are looking for a portable, feature-packed HF rig without breaking the bank. For portable operation, it’s hard to beat!

HF operations from a narrowboat

"Well that's something you don't see everyday!"...as they say. And it isn't, although I have seen other narrowboats on the UK canal network with what I assume are amateur radio antennas. But not many. 

I have also seen a small number of boats with what I assumed were CB radio antennas. Whatever floats your boat, as they say!

Those amateur radio narrowboats that I have seen usually have an assortment of VHF/UHF whip antennas and at least one, but usually more, end fed wires for HF, with an assortment of steel or telescopic carbon or glass fibre supporting masts. As is typical of the amateur radio operator, there is no lack of engineering ingenuity or creativity when it comes to erecting an effective antenna farm within your own specific constraints.

This is the narrowboat in question with a somewhat closer view of the antennas. I'd love to know the callsign of this operator because as much as I tried to exchange callsigns verbally we couldn't hear each other as we were some distance apart by the time he emerged from his boat.

If this was you, or you know who it might be, please comment below.

K5D - Desecheo Island

The very smart K5D QSL card

The QSL card arrived today and a very nice card it is, befitting the dxpedition itself which was a slick, well run affair.

I was very pleased with my 30m CW contact because prior to the night I made the contact I’d struggled to hear them at all. Add to that the huge pile-ups I was convinced I’d never get through. But, on the night of the 22nd February 2009, they were much louder so I set about making a few calls, trying to find my way through the pile-up. Half an hour later they were in the log.

I’ve had some good successes on morse code over the past year or two with VP6DX and K5D as two contacts of note. I next hope to work El Salvador for an all time new one later this month when a British team will be operating exclusively on CW as YS1G. Fingers crossed there is some decent propagation come the time.

G0RIF portable from Barr Beacon

Just a few words on todays operation from Barr Beacon (IO92BN) when I setup on 20m with the Par End Fedz 20m dipole suspended vertically on a 10m fibreglass pole.

Band conditions weren’t great and there was fast deep fading. Not as bad as 17m at the weekend but still pretty dramatic. Best DX was VE1ZA/m (Tony) followed by OH0/DL9GTI (Ralf). It seems Ralf wasn’t the only German out and about as I also worked Peter in Croatia as 9A/DL4KM/p and Charlie in Italy as I/DL3KHK. In keeping with this ‘operating abroad’ theme I also worked Dave in Menorca as EA6/M0DLL.

All in all it was an enjoyable few hours on 20m when even the weather was pretty good…until the battery was run down and I’d packed everything away, after which it poured it down. I think I timed that perfectly! 

QSL cards received this week from 6Y1V and KL7RA

KL7RA and 6Y1V QSL cards

Here we have a few interesting cards received this week for contacts in the CQWW CW contest in November (6Y1V) and the CQWW WPX CW contest back in May (KL7RA). Both of these are in response to direct QSL requests.

Alaska (KL7RA) was an all time new one for me at the time so it’s nice to get that confirmed for number 153 (of 170) confirmed by paper QSL.

6Y1V (on 40m) was a highlight on the recent CQWW contest and I had a pretty quick response via the QSL manager in Finland (Kari, OH3RB) which was nice. The card also confirms a 20m and a 40m contact from the WPX CW contest in May.

In other news, SpaceWeather.com reports that sunspot 1035, having burst onto the scene 3 days ago, continues to grow and is crackling with C-class solar flares with a chance of M-class flares.

CQ contest: Starting your contesting journey

Radio contesting, or "radiosport," is a popular way for amateur radio operators to test their skills, equipment, and strategy by making as many contacts as possible in a set period. 

I enjoy contests because it usually means that the bands are alive with lots of nice DX and as much as I don't keep score or submit logs, I do like to make as many contacts as I can during each contest just to make the most of the elevated levels of activity to be enjoyed at these times.

CQ World Wide WPX (CW 2009) - my 52 countries worked during the contest

However, if you want to take contesting more seriously, for operators in the UK, there are several routes into contesting, each offering unique experiences and learning opportunities.

1. Participate in RSGB weekly contests

The Radio Society of Great Britain (RSGB) runs a variety of contests that are perfect for beginners. These include HF contests like the RSGB 80m Club Championship and the UKAC (UK Activity Contests), which are held on different HF, VHF, and UHF bands throughout the month. VHF and UHF contests are particularly accessible to those with basic equipment and smaller antennas, as they typically involve shorter-range communication, making them ideal for operators in urban areas or with limited space. Participating in these contests allows you to familiarise yourself with contesting procedures and improves your operating skills in a structured, yet relaxed environment. The RSGB also provide a lot of useful information here: https://rsgb.org/main/radio-sport/radcom-contesting/

2. Join a local Amateur Radio Club

Many local amateur radio clubs in the UK have active contesting groups. By joining a club, you can benefit from the collective experience of seasoned contesters and access to club equipment, which may be more advanced than your own. Clubs often participate in RSGB contests as teams, which is a great way to learn from others and get involved in the community. Clubs such as the Drowned Rats Radio Group and the VHF Contest Club are known for their participation in VHF and UHF contests, providing opportunities to operate in a group setting and learn about different aspects of contesting.

3. Engage with online contesting communities

Online communities and forums provide valuable resources for new contesters. Websites like the RSGB Contest Committee's site offer detailed information about upcoming contests, rules, and results. Engaging with these communities allows you to ask questions, share experiences, and gain insights from more experienced operators. The UK Contest Reflector and the VHF Contest Forum are popular places where UK contesters discuss strategies, share tips, and organise activities.

4. Explore VHF and UHF contesting

Contesting on VHF and UHF bands provides a different set of challenges and opportunities compared to HF contesting. These bands are affected by different propagation modes, such as tropospheric ducting and Sporadic-E, which can lead to surprising long-distance contacts. VHF/UHF contests often have a regional focus, making them accessible to operators with basic equipment. Participating in these contests helps you understand the nuances of these bands, such as the impact of terrain and the importance of antenna height and gain.

5. Contest Logging Software

Effective logging is essential for successful contesting. Contest logging software, such as N1MM Logger+ or Win-Test, is widely used to track contacts, score accurately, and manage log submissions. These tools are particularly useful in contests that involve rapid exchanges and numerous contacts, as they help prevent duplicate contacts and errors. Familiarising yourself with logging software will improve efficiency and accuracy, making the whole contesting experience more enjoyable.

At last, an antenna that works!

Originally posted on 'The wet string chronicles' in April 2009. 

Last night I put up an antenna for the 6m (50MHz) band. I built the antenna several weeks ago to a design I found online - the antenna is called ‘the mighty wide 6m dipole’ (by Brian, G0IER). The ‘mighty wide’ bit refers to the bandwidth of the antenna. The broadband nature of the antenna is desirable due to the width of the 6m band, a full 2MHz.

Once built and tuned this antenna exhibits a flat SWR plot across the whole of the 6m band. I used the antenna for the first time tonight and had a lengthy chat with Richard (M0SNR) down in Castle Bromwich. Running just 20 watts output he gave me a good readability 5, strength 8 report.

The antenna is deployed in a stealth configuration running along the top of a 6 foot high storage unit in the top bedroom. The good news is, it works!

My first experience with the Reverse Beacon Network

The amateur radio Reverse Beacon Network (RBN) is an innovative system that has revolutionised how ham radio operators monitor and analyse radio propagation. Unlike traditional beacons that transmit signals for others to hear, the RBN uses a network of automated listening stations around the world to detect and report amateur radio transmissions.

These listening stations, often called "skimmers," employ clever software that continuously monitors multiple amateur radio bands. When they detect a CQ call (or other transmission that they recognise), they report the signal's frequency, strength, and other characteristics to a central database. This information is then made available in real-time to radio enthusiasts and researchers worldwide via the internet.

The RBN provides valuable data for understanding radio propagation conditions, helping operators determine which bands are open for communication and where their signals are being heard (in much the same way as PSKReporter does with digital mode transmissions). It is particularly useful for contesting, DXing (long-distance communication), and studying the effects of solar activity on radio transmissions.

Since its inception in 2009, the RBN has become an essential tool in the amateur radio community, enhancing operators' ability to make contacts and contributing to our understanding of radio wave propagation. 

Being somewhat late to the RBN party (due in large part to my extended periods of inactivity), my first use of this facility was yesterday (23rd August 2024) when I was setting up an automated CW keying interface between my computer and Xiegu G90 radio.

Having established that my keying interface was working, I tuned up and down the lower end of the 15m band and I heard not a single CW station. Granted I was only using a 1/4 wave vertical antenna and conditions weren't great at that time of day, but I was a bit surprised to hear nothing. 

This led to my putting out a succession of CQ calls (5w output, with no responses) to see if (or where) I might be heard by the receiving stations of the reverse beacon network. Within a minute or two I was seeing RBN spots for my signal received as far away as the east coast of America (where I suspect their antennas were doing much of the heavy lifting) and Asiatic Russia, as shown on this screenshot I took at the time.

RBN spots for my 5w CQ calls

Tools like the RBN and PSKReporter are very useful tools when it comes to gauging propagation from your location because they provide real time feedback of exactly where your transmitted signal is being received, and from where you might expect a few replies if you put out a few CQ calls. I will certainly be using the RBN a lot  more in the future.
