If you remember my previous post where I commented:
“Onwards and upwards so…. Happy 4th of July to my American Friends…. I’ve already gotten 7 of the 13 Colonies station in the log and I started chasing them today.“
So it would seem that last evening I waslucky/skillful enough to get the remaining 6 colony stations in the log along with the WM2PEN Bonus Station in the log.
Last night I did hear the GB13COL Bonus Station on 20m ssb and could not break the pile up.
This morning I did hear the TM13COL Bonus on 15m cw but once again was unable to break the pile up.
So far out of the 14 contacts ( 13 colonies and 1 Bonus station) 3 contacts were made in CW and 11 were made using SSB.
Power levels are 90w for SSB and 40W for CW.
I’m (foolishly) feeling confident that before the event ends on July 7th I should be able to complete the SWEEP including the 3 bonus stations.

This weekend is the ARRL June VHF contest. Its a fun way to test our your VHF Capabilities and your antenna systems…
The following is a “cut N paste” from the ARRL Website:
About
Contest Objective: For amateurs in the US and Canada (and their possessions) to work as many amateur stations in as many different 2 degrees x 1 degree Maidenhead grid squares as possible using authorized frequencies above 50 MHz. Stations outside the US & Canada (and their possessions) may only work stations in the US (and its possessions) and Canada.
Dates: The second full weekend in June. (June 8-10, 2024)
Contest Period: Begins 1800 UTC Saturday, ends 0259 UTC Monday.
Now this is a busy weekend for me (radio wise) as the Rideau Lakes Cycle Tour will be in Kingston during that time and its the only scheduled Public Service Event that our local group does every year.The picture on the left was taken the first year I assisted the Kingston Group on the event. Previous to that I lived in Ottawa and I participated with the Ottawa Group on the same event.
Using my Yaesu FT991a I plan to be giving out the “Rare FN14” Grid square on both 2m and 6m SSB.
On Saturday my Bike tour shift will finish around 6pm (EDST) or 2200 (UTC) if I did the conversion correctly… So I plan to operate from 2300 UTC for a couple of hours.
On Sunday my tour will finish around 9am (EDST) or 1300 (UTC) once again if the conversion works and will try again then around 1400 UTC once I get home.
My 2m/70cm antenna will be a simple Halo or loop which will be horizontal at approx 20 feet above ground. The 991a has an output of 50w ssb on 2m. As the loop is “sort of” useable on 70cm I will be able to give some locals an extra multi.
My 6m antenna will be a simple “Buddipole 6m Dipole. The 991a has an output of 100w ssb so it should be able to get a bit of a signal out across the Lake (at least I hope it will).
Later tonight there is a vhf net that starts on 144.250 usb that is based in Eastern Ontario. Check out the West Carleton Amateur Radio Club for more into on that. After that they call the role on 70cm and 6m. I stand a change on 6m and 2m if someone has their beams aimed southwest. More on how this works later.
Lets see who can hear the “Popgun” with the tiny antennas…

Spains Atlantic coast
Out of the corner of my eye I’ve watched his movie. It didn’t really matter that I couldn’t hear anything as it was in Spanish, set during the Spanish Civil War and actually looked quite good. Boredom had me restless and I rifled through the Iberian in flight magazine that like so many has airport maps, pictures of unbelievable cuisine and something that absolutely caught my eye. Asturias; mountains, coast line, royal palaces and of course cuisine. I’m sold.
Interrupted by Covid and years later, I find myself driving toward what I thought would be a great first Spanish peak. The barrier was unmistakable and the bright neon lights declaring no entry without reservation was not what I wanted to see this early AM.
“Do you speak English?”, “Yes” she replies telling me that twenty minutes earlier, I could have driven in but now and without any reservation I’m out of luck. Come back tomorrow but that isn’t really my plan as I have this not so carefully planned trip to climb peaks, see Vitoria’s (1813) geography and then enjoy Bilbao and aspects of the Basque Country.
The idea of speeding is silly and really isn’t an option. The mountain roads are very narrow, climb relentless and wind and wind around a geologic marvel that is the Picos de Europa National Park. It’s July and while not a big destination for foreigners, it’s super popular with Spanish and I’m convinced my late arrival will yield no parking spot and all in all I’m skunked.
The downside to parking in Sotres is the 500 ft decent to then start a 2,200ft ascent but I have a space and walk down the paved road trying hard to determine which peak is mine.
Just outside Stores and heading down and down and down
Rustic buildings
Steep ascent, pack is far too heavy and shoes were a poor choice….but it’s worth it all
6,000ft on the peak and the views are stunning
A very fancy peak marker
45 contacts later and I’m smiling away….857D and big battery were overkill
Mainly 20m voice contacts across Europe and a few local on 40m
Above the clouds and always mindful that the weather was forecast to possibly rain
Long journey from Sotres to peak ad back
The car pulls up next to me and the window winds down. “Sorry, I don’t speak Spanish” is my reply to her. “Would you like a ride?”. Thinking wasn’t required and I blurted out “yes!!”. Pilling in the back they inquire where I have been. The story of mountain top radio needs a little explanation. The three young hikers were very curious about my peak and I surmised my paltry 8 miles and almost 3,000ft was just a warm up for them. Nevertheless, this Basque Country trio are charming and pretty much take me right to my car. Absolutely a Godsend as I was knackered.
Thirty euros buys me all I can eat at the hotel for dinner and then I discover it includes all you can drink….wine, beer….
Perfect place to hang out, read, drink and admire the view from the hotel patio

Like most Brits, I love Spain, I really do. The south is a big attraction with its warm weather, beaches and sometimes Fish and Chips. In stark contrast, the Atlantic Coast of Spain is green, wet and a place less trodden. It’s been a desire of mine to hike/drive west along the Pyrenees and then along the Atlantic coast to that little know Napoleonic debacle that was the evacuation via Corunna (1809). Another day, sooner than later.

Since setting up the new HAM station here in the UK the one band I’ve not yet got back onto is 160m, one of my most favourite bands in the HF spectrum and one that I was addicted to when I live in France (F5VKM).
Having such a small garden here in the UK there is no way I can get any type of guyed vertical for 160m erected and so I needed to come up with some sort of compromise antenna for the band.
Only being interested in the FT4/8 and CW sections of the 160m band I calculated that I could get an inverted-L antenna up that would be reasonably close to resonant. It would require some additional inductance to get the electrical length required and some impedance matching to provide a 50 Ohm impedance to the transceiver.
Measuring the garden I found I could get a 28m horizontal section in place and a 10m vertical section using one of my 10m spiderpoles. This would give me a total of 38m of wire that would get me fairly close to the quarter wave length.
For impedance matching I decided to make a Pi-Network ATU. I’ve made these in the past and found them to be excellent at matching a very wide range of impedances to 50 Ohm.
M0AWS Homebrew Pi-Network ATU
Since I still had the components of the Pi-Network ATU that I built when I lived in France I decided to reuse them as it saved a lot of work. The inductor was made from some copper tubing I had left over after doing all the plumbing in the house in France and so it got repurposed and formed into a very large inductor. The 2 x capacitors I also built many years ago and fortunately I’d kept locked away as they are very expensive to purchase today and a lot of work to make.
Getting the Inverted-L antenna up was easy enough and I soon had it connected to the Pi-Network ATU. I ran a few radials out around the garden to give it something to tune against and wound a 1:1 choke balun at the end of the coax run to stop any common mode currents that may have appeared on the coax braid.
Connecting my JNCRadio VNA I found that the Inverted-L was naturally resonant at 2.53Mhz, not too far off the 1.84Mhz that I needed. Adding a little extra inductance and capacitance via the ATU I soon had the antenna resonant where I wanted it at the bottom of the 160m band.
M0AWS 160m Inverted L Antenna SWR Curve
With the SWR being <1.5:1 across the CW and FT8 section of the band I was ready to get on 160m for the first time in a long.
Since it’s still summer in the UK I wasn’t expecting to find the band in very good shape but, was pleasantly surprised. Switching the radio on before full sunset I was hearing stations all around Europe with ease. In no time at all I was working stations and getting good reports using just 22w of FT8. FT8 is such a good mode for testing new antennas.
As the sky got darker the distance achieved got greater and over time I was able to work into Russia with the longest distance recorded being 2445 Miles, R9LE in Tyumen Asiatic Russia.
In no time at all I’d worked 32 stations taking my total 160m QSOs from 16 to 48. I can’t wait for the long, dark winter nights to see how well this antenna really performs.
M0AWS Map showing stations worked on 160m using Inverted L Antenna
The map above shows the locations of the stations worked on the first evening using the 160m Inverted-L antenna. As the year moves on and we slowly progress into winter it will be fun to start chasing the DX again on the 160m band..
UPDATE 6th October 2023. Been using the antenna for some time now with over 100 contacts on 160m. Best 160m DX so far is RV0AR in Sosnovoborsk Asiatic Russia, 3453 Miles using just 22w. Pretty impressive for such a low antenna on Top Band.
Going through some old photos today I found a few great memories from the past of my old valve radio stations that I’d restored over the years.
These old radios gave me some wonderful moments over the years and a fair few hours of restoration to get them into operational condition. They sounded great on air and I often got comments from other amateur stations about how warm the audio sounded. Some did also mention the drift of the transmitter with temperature changes but, you just have to accept that when using vintage radio equipment.
M0AWS FT101E Transceiver, FL101 Transmitter, FR101B Receiver and TS520S Transceiver.
Above is my old FT101 line up. It consisted of the great FT101E transceiver, a complete standalone solution that was extremely popular in its day. Below it is the FT101 line up made up of the FT101 transmitter, FR101B receiver and matching speaker.
Top right is the lovely Trio TS520S with the matching digital frequency display which is incredibly rare and very sought after today.
These radios gave me a lot of pleasure for many years and I wish I still had them today.
My second Yaesu valve line up took a lot more restoration than the 101 series and was quite challenging at times but, with a lot patience and time spent sourcing parts I got them back to as close to new operational condition as was possible.
M0AWS FLDX400 Transmitter, FRDX400 Receiver, FL2000B Amplifier and FTDX501 Transceiver.
The Yaesu 400 series line up consisted of the FLDX400 transmitter, FRDX400 receiver and was finished off with the FL2000B amplifier. These 3 pieces of radio equipment looked beautiful in the flesh and were wonderful to operate. Taking a good 15mins to warm up and become stable you couldn’t rush getting on air. This line up was my favourite by far even though they weren’t as good as the 101 line up.
Above the 400 series is the later FTDX501 transceiver with matching speaker. This was a great radio in its own right but, not as much fun to operate as the 400 line up. To the right of the FTDX501 is the matching Yaesu Microphone for the 400/500 series. This mic is incredibly rare and I had to visit many radio swap rallies to find it, worth the effort though.
Top right you can see my old SWL receiver, the great Drake SW4A. I never had a Drake line up as they are quite rare in the UK but, it certainly would had made a great addition to the station.
M0AWS FLDX400, FRDX400 & FL2000B Station being operated by M1ACB and G6ALB
Finally this is a photo of two friends of mine, Steve Thomas M1ACB (Current General Manager of the RSGB) on the right and Andy, G6ALB with whom I spent many hours sending and receiving morse with to get our Class A licences. We had a fun day together operating the old radios and taking it in turns to handle the pile ups!
R&L Electronics sent me a SCU-28 10-pin DIN cable by accident and were nice enough to let me keep it. Consider shopping from those guys. They offer great communication and good prices.
This cable is typically used to wire connections for an external amplifier. I don't have an external amplifier but I wanted to make use of the +12v power and transmit relay for the protection relay I built for my SDR-Play a few years ago.
I had also read that the TX REQ IN pin could be used to switch the radio into a lower power tune mode for use with external tuners. The absence of a TUNE button for external tuners is one of my pet-peeves about the FT-DX10 so I was excited to have one.
Wiring the Break Out Box and TX-REQ-IN
So I used my last spare plastic project box, some female phono jacks and found a push-button that I'd cut off of some other project in my junk box and went to work.
I used some shrink wrap for the momentary switch for the TX-REQ-IN pin.
I wired up 3 phono jacks... One for the TX relay, another for the +12v out, and one for the ALC control in case I ever do get an amp. I safed the other wires for future use inside the project box.
Partial Success
I connected the box and verified that I was getting power for the relay and that the Relay Switch operated
Unfortunately, the TX-REQ-IN does NOT do what it does with other Yaesu transceivers. Pressing the button grounds the TX-REQ-IN - the radio does transmit a carrier in any mode (here I tested with LSB) but rather than transmitted a reduced power carrier as it's supposed to, it just transmits at whatever wattage the mode is currently set to. In this case I had the power set to 50w into a dummy load and it transmitted the full 50w rather than a reduced power 10w or 20w carrier for tuning. See the power out on the radio's display
In my opinion Yaesu screwed the pooch on this one. I don't see any reason why they wouldn't operate like they do with their bigger brethren radios when the TX-REQ-IN is grounded. Some subsequent forum searching turned up posts from others that confirmed that the FT-DX10 does not properly respond to that signal.
My Elecraft KX3 and Ten-Tec Eagle both have a "TUNE" button that sends a low power tuning signal regardless of what the current power setting is at and there's no reason that the FT-DX10 shouldn't do the same. Having to dive into a menu to change the power setting for tuning an external matching unit is just silly in this day and age.
The Yaesu FT-DX10 comes standard with a 500 Hz crystal (xtal) roofing filter, but offers an optional 300 Hz roofing filter. Should you purchase the optional filter?
The 300 Hz roofing filter is twice the size of the 500 Hz filter so it must be twice as good right?
If you casually switch back and forth between the two filters on a noisy band, it sounds like the 300 Hz filter markedly improves selectivity and quiets the noise. But try this: Select the 500 Hz filter and narrow the bandwidth (using the bandwidth control) to 300 Hz, then switch to the 300 Hz filter.
When you digitally narrow the bandwidth of the 500 Hz filter to 300 Hz you will "hear" the same reduction in noise as you have cut out 200 Hz of higher frequency sound. Engaging the 300 Hz filter lowers the volume a bit (3-6 dB) due to insertion loss.
So what you are actually "hearing" when you switch back and forth between the filters without changing the digital bandwidth is the reduction of the higher frequency noise that can be accomplished using the bandwidth control alone with the 500 Hz filter.
So, from a selectivity standpointthe 300Hz filter doesn't gain you anything over using the digital filtering with the 500 Hz filter. The real benefit should come in the form of adjacent signal rejection. So let's look at that.
In the video below I demonstrate the signal rejection of a 40 dB over S9 adjacent signal to a weaker S3 - S5 signal.
From the video you can hear that there is a very small demonstrable difference in strong signal rejection when using the 300 Hz optional filter, but the difference is so small that I doubt many of us would find practical benefit over simply narrowing the DSP bandwidth while using the 500 Hz filter. Even when contesting. The digital filtering built into the FT-DX10 is really, really good when using the included 500 Hz roofing filter alone.
Yes, I spent the $200 for the optional filter thinking it would help, but I wished I had known what I do now. I would have $200 for some other nifty radio gadget to spend instead.
