Home brew 40-80 Balanced Fan Dipole

Hi All! Hope you are keeping safe... We are in the same position as most regarding lock down and other than going to work I have been stuck indoors a lot lately. So, off outside into the garden it was and antenna building time once again was here. 

I decided to replace the prototype 40/80 fan dipole that has been in use since the end of spring. It has been working really well even though I made it from some random used wire, I bought three reels of SotaBeam military spec heavy duty wire which come in 50 meter reels. The wire is stainless coated multi strand 50 ohm and is in a low impact green colour. It is very good for antenna elements or radials and solders up nicely. 

I also decided I wanted to try out this new build double dipole with a suitable 1:1 balun that would help prevent unwanted coaxial line transmission and also help reduce unwanted reception noise on the feed line from random electrical sources nearby. The balun also helps to isolate the returning RF at the feed point and balances the dipole elements to 50ohm, as well as helping to produce a more effective radiation pattern on the transmit signal generated.

I looked into making my own, but in my possession had a gift voucher to spend on Amazon. So I opted for a commercially built balun capable of handling my 400 watts. I ended up with the Diamond BU-50A which is a really neat piece of kit.

I made a step by step video on how to make your own 40/80 fan/balanced double Dipole, If you want to have a go watch the video below. 

Step by step how to make a 80/40m Fan Dipole with 1:1 Diamond BU-50A Balun

The result is great! I have 1:1 - 1:5 across the full 80m band without any need for an ATU and the same  1:1 - 1:5 also on 40m after a slight adjustment. I had made the antenna slightly longer and had to cut the legs equally to achieve the best match. The reception clarity has improved on both bands and the noise has lowered in strength. My out going signal as ever, is good to go and I will be DX hunting over the winter months! Thanks for passing by catch you soon. 73 Stay safe!

Autumn - Winter HF DX - What to expect

 

As we move into the last couple of months of 2020 which has been defiantly a year to remember for obvious reasons, we can look forward to getting back down to the lower HF bands such as 80m.

I really enjoyed the winter DX last year and made plenty of good qso across to USA, Canada, Caribbean and South America whilst operating on the 80m band.

This year I have the 40m/80m home brew Fan Dipole which has already proven to be an awesome asset to my HF station. For those of you that have been coming back to my call on the regular YouTube live streams you have already sampled its performance h.i. Thanks for the super qso's guys, I look forward to catching you all again over the weekend this coming Saturday evening about 10.30pm local (21.30 utc).

So, the homebrew Fan Dipole worked out well for me. I must admit I am quite impressed with it, I have some brand new SOTA beam wire reels in my possession which at some point will be used to build a brand new replacement which will be cut to the same length and installed to the same fixing points and configuration. At present the Fan Dipole is up at 30ft with each leg fixed in a straight line face North to South with a total length of 131 ft. The SWR on both bands 40 and 80m is 1:1 - 1:4.

This week I made a 80m DX qso across the pond and worked Big Gun remote Op Ray W2RE on the DX portion of the band. I was 5/7 at rays end and it was quite early in the evening over at my QTH and daylight in the USA. I have also worked into Canada recently and heard other North American signals coming in well recently. I am expecting plenty of decent signals from now on as we draw closer into the winter months down on the 80m band which I will use the Dipole and amplifier to make some good DX. I will also enjoy hearing the old timers make DX in the early mornings as i eat breakfast and drown myself in coffee. This is almost a religion for me during the 80m DX season and I hear the same 80M DX chasers year in and year out. I enjoy hearing them on their switchable four square arrays and obviously when they are far away and exotic I love trying to work them. Its a good time to get on 80m if you haven't done it before and listen to how some of the seasoned DX operators work others, they also will be interesting DX nets on an evening run by experienced radio amateurs out of Europe and North America. Most of these radio amateurs will come back to your call if you follow the DX code of conduct which is basically be patent, polite and listen for your opportunity to call. Sometimes you wont hear the stations that they will be hearing so you have to sit on the side and listen for a while first. Its great fun and like I said already well worth trying out if your new and haven't yet.

 Other bands such as 40m are generally good for DX all day and night during the next coming season and again the 40/80m fan dipole seems to be a kick ass antenna for me so far. I also have the 6 band vertical - Hustler 6BTV and recently refit a new tube section to the bottom 10m element/section. This vertical has served me well and definitely works well with a few radials. I like it a lot and it sometimes has the edge over the dipole on the 40m band. As for 80m its a great receiver but is narrow banded on transmit meaning the use of ATU is necessary.

20m is up and down but has been providing some good DX openings here and there so I will be always listening around the band for activity. The same goes for 17m through to 10m, catch it when its there and always worth a quick check. With a bit of luck the FM repeaters from the USA will be coming through up on 29MHz if we get any propagation. Its another great thing that happens from time to time during the winter months.

That's about it for now, hope your all keeping well and staying safe as possible. I am working back at College fulltime and really enjoying the company of my learners. We are working as safely as possible and at the same time trying to get on with life which is a lot more interesting than when I had to stay home back in full lock down. Our region is classed as ''high risk'' and a few staff and students have been affected but thankfully all have made full recoveries with nothing two terrible whilst being ill. We have masks on and welding headshields with extraction and the cleanest hands you have ever seen on a welder so with a bit of thought, consideration and common sense we should hopefully continue on through the other side eventually. 

Look forward to catching up with some of you on the bands and of course YouTube! Thanks for passing by my old time blogg. Have a great weekend!

Lots of ISS and Satellite activities as HF is quiet

 Hi everyone I hope all is well? It's been a couple of weeks since I last posted so thought I'd drop by and update you of some of the activities I have been getting on with.

First I will start with the card I received this morning confirming a great qso with ON3ONX who was worked via SSB Satellite XW-2A. 

Over the past fortnight I spent a number of evenings trying my hardest to get into the new ISS repeater, I have probably tried around about 50 passes which I would say out that I made a qso 5 times giving me a 10% success rate. At first I thought I had an issue at my end but soon realised that the majority of stations in the UK and N.W Europe that were getting in each time (the same stations) are in fact running higher power than myself. This of course is quite unnecessary as well as out of order lol. I guess some people are so desperate to make it their own personal repeater hi hi that 300w is acceptable. I cranked it up to 50w and still struggled and at one point went the whole hog of 85w to try prove a point - still did not get in lol. 

2M0SQL- Peter who has a great satellite station dropped me a message informing me that the squelch level onboard ISS has been turned up high. This would explain why the up-link signals are struggling to open the repeater up and when they do work, cut out a lot.  Thanks for the info Peter. 

The other earth orbiting satellites such as AO-91, SO-50, XW-2A and RS-44 have been absolutely solid at my end. I have really been enjoying myself working lots of amateur stations on these satellites and I did manage a DX contact via RS-44 into Canada where I worked VE1VOX - Dana. That was cool!

My 145MHz Yagi has been vandalised by our feathery friends and I have lost half of my reflector when a big Owl decided to adjust their perch. I haven't noticed any detrimental changes to performance other than it looks and is annoying lol,  maintenance and repair/replacement is planned for the end of the month when I get the half term holiday. 

Everything else apart from HF propagation seems to be going well, I am flat out at work teaching the latest generation of welder fabricators which is great despite wearing a face mask all day for protection against the dreaded C19. 

I also did a bit more work on the tower I started a while back and finally brought it home to complete the bits and pieces at home in my spare time (if I get some lol). The plan is to fit a tilt over bracket and tube clamp to allow a telescope type height adjustment.

So that is about it for now, Oh i almost forgot.... I have been banging out lots and lots of videos on my Ham radio YouTube channel so if you haven't seen them all yet lol why not take a look! My channel is growing in popularity lately and I want to thank everyone for their support with this. I know some of you have been there from the beginning and I value your loyalty a lot! Thanks guys and girls. 

Hope to catch some of you soon! have a lovely weekend all 73 de M0YKS Simon

Amateur Satellite Bands

 Its been just over a month since I purchased the COM 232B antenna rotator interface. 

The neat little box sits nicely on my G-5500 control unit and is hooked up to my Windows 10 PC running Orbitron and WiSP DDE tracking software.

The auto tracking of the antenna has made making a contact into the satellites much easier allowing me to focus on the reception and uplink signal out from my FT-847. I am looking at the next step which is configuration of the cat control for auto frequency doppler correction but at first glance its a bit of a faff and is not something I have the time to commit to setting it up properly at the moment. However, I spent a couple of hours last night trying to get it functioning on Orbitron but had no success so far. I more than likely will have to try something else if I want the auto frequency control, possibly GPredict. 

I made a new video of my satellite operation which features CW, SSB and FM communication. Best 73 from the family and myself and we will catch you soon. 

BTW back at work full time. Stay safe everyone!

FlightAware Aircraft Tracking on 1090 Mhz - Improving the range

 The FlightAware setup that I received from my good friend Pat W1DUK recently has been performing really well with the "Cantenna" 1/4 wave vertical antenna for 1090MHz. The set up comprises of a raspberry Pi with a FlightAware SD card and a FlightAware SDR USB Dongle, into a 1090 Mhz Antenna.

Today I was up early and with a freshly fabricated bracket I managed to clip the Cantenna up high in the sky on the top of the mast. The reception footprint has now become up to 200 miles and possibly further with a greatly improved omni-directional pattern. I am in the first couple of hours of testing and have seen the number of aircraft increasing from an average of 10 to 20 + aircraft at once being tracked. A great success so far!

A screen capture taken with my first go using the "Cantenna" 1/4 wave vertical mounted in the top window inside the house

Hope you found this interesting! Its great fun to do and relatively low cost! Once again Thank You Pat W1DUK and the guys and girls at Ham Radio Outlet for this awesome gift! I have really enjoyed trying it out and providing the feedback and will continue to play! 73 All.

Signal Report From South Korea - HL2-0112B

This morning I was pleased to receive an email form Kwon -HL2-0112B from South Korea. Kwon had received my signal whilst I worked OZ/DB4ST  up on the 20m band. I will be writing out a QSL card for Kwon shortly, thanks for the report Kwon! 73 to South Korea hope to make it to your SWL station again soon Thank You!

Nice DX Opening Into Montserrat and USA - Late Night DXer

Messing around in the shack late night DXing paid off again,  I caught a couple of nice QSO just now into Montserrat and the USA. First I worked Micheal W3MLJ operating on a remote station he was 5/9.

After that I worked Frankie VP2MNI who as usual was booming in with a solid S9 from Plymouth Montserrat. Both stations were worked on the 20m band. Thanks for the QSO guys!

Face Lift For Longest Running Ham Radio Blog In UK

I had tried my best to avoid any changes to this well established old blog of mine, but due to constant changes such as templates and securer viewing and privacy settings I have been over ridden by blogger and the whole blog has had a makeover. This happened of course without my blessings or consent but I suppose It was inevitable as more and more people bin their PCs and browse the web on phones, tablets and I-pads. I myself do use all of the above apart from I pad due to costs lol But! I also still do most things on my desktop Windows 10 PC and have no plans to get rid of it!

So, here it is.....Bloggers supposedly better template which is pretty basic without the cluster and ISS tracking and of course very well visited flag/site meter no longer with us "Doh"

Thanks To Everyone that has passed through since 2006 and hopefully will still continue to do so! Check back soon I should have got over the shock by then and be posting HAM Radio Epic Content lol.

How to work Amateur Radio SSB Satellites - Demo Video By - M0YKS

You may have missed me on the Satellite bands as my antenna required a bit of maintenance which I managed to get sorted yesterday!

It was not my favourite pass time but all went well and I was back on the satellite bands later that same day.

I made a little mini Satellite series on video which starts with PT1 - a antenna test and demo - Moves on to PT2 - How to make an SSB Satellite QSO - Ending with Part 3 which was an actual QSO Via an SSB satellite with Peter 2M0SQL.

There's a voice inside the static

And it's calling out CQ

CQ DX is anyone there?

He wants to speak to you

You've set up your antenna

You're receiving loud and clear

You're going to call out to the voice

That you can loudly hear

You shout out your callsign

He says he can hear you fine

Receiving you above the noise

Your signal's 5 and 9

You exchange all of your info

Find out what you want to know

Say 73s and 88s

QSL via the bureau

A new one for 2020
QRZ? Keep calling
I hear you in the noise
Conditions might be changing
As I can hear your voice
I know it is frustrating
Keep trying you'll get through
I can hear your voice in there 
As I call CQ
It doesn't matter where you are
I just like the conversation 
So keep calling, hopefully
We'll have good propagation 
I want to get you in my log
And to hear what you've got to say
So please keep trying to get through
Point your antenna this way

HF Amplifier repair

Last week I had a slight misfortune with my GI7B valve amplifier. As I was coming to the end of a session in the shack I had made the mistake of operating without the cooling fan on full speed which resulted in a resistor overheating whilst tuning up during a change of band. I ran a bit too much anode current during a tune up which combined with the lack of cooling was too much to get away with.
The followin day, I took a careful approach and inspected the amp thoroughly for any other damage. The resistor, a 2watt 1ohm resistor was easy enough to replace and once I completed the repair and replaced the fuse I was back up and running. Whilst I had the amplifier apart I took the time to clean out the accumulated dust and also got to know exactly how it all functioned. Simple enough and very well constructed.

This Weeks DX Summary

The past few weeks have flown by, I have continued working online with my college students and staff which has been very busy and productive. On an evening I have made the most of the DX opportunities and managed some great DX most nights. Check out the past couple of weeks log entries...... Lots of Great DX....Plenty of decent into G conditions also.....

I have been catching my DX action on video and live stream on both my Ham Radio YouTube Channel and Facebook Group Ham Radio Operator Live Streams.

You can catch a couple of the videos here:

The bands are certainly picking up late on in the evening at the time I like to be active and I keep getting some great Stations in the log. I have also enjoyed meeting a lot of you guys on Facebook and getting to know you all a bit better. Thanks!
Have a great weekend Catch you soon 73! M0YKS Simon

Demo Of How To Work SSB Satellites

Hi everyone hope your enjoying the sunshine and if your reading from across the globe heading into the winter months I hope you are also having a good day. Its the hottest day of the year here in Baildon W.Yorkshire UK. I awoke this morning in my garden camping which was fun with my family, shortly after I was active on the Satellite bands trying to make a QSO. I did not make QSO this time but did get my signal into XW-2B quite nicely.

If you want to see the way I use CW to help locate my own signal on the down-link satellite band watch the video. I find this is the easiest way of getting a good up-link to the satellites that operate linear SSB transponders which in simple terms means: TX-UP On 435.100 LSB &  RX-Down 145.740 USB. Most SSB Satellites operate with both USB and LSB. The frequency is for XW-2B not all SSB Sats.

Out Of This World

What an exciting weekend

Hope you're all well, as you can see I have been having fun with the family watching the launch followed by camping in the garden.
