I’m excited to try out a new antenna I’ve been working on. It’s an adapted take on a design by DJ0IP for a 160/80m antenna on an 18m pole. The original desin of this antenna (pictured below) is a top loaded vertical for 160 with an 80m Inverted L hanging from the side.
Here is the DJ0IP design, Credit: http://www.dj0ip.de/vertical-antennas/160-80m-on-18m-pole/
I will say early on that I am not an expert, just an experimenter. The M0SDV design is slightly different. There is no shared feed point, and No shared ground plane. Instead they are two independent mono band vertical antennas from the same mast. This is an 18m spider beam pole. The 80m vertical is 1/4 wavelength with 2x elevated radials approximately 3m above the ground. To allow for a wide spaced coil at the base of the antenna I have built a frame from plastic tube to separate the 160m and 80m elements by 1m.
The 160m antenna is a “T” vertical using approximately 17m vertically and each leg of the top hat is about 15m long. This is over a pre laid ground plane. You might be wondering what I have used for the ground plane. I am not sure how effective this will be but like I said, I am an experimenter not and expert. Due to lack of space in my garden my radials are between 16m and 20m long going is multiple directions. This idea is taken from M0MCX at DXcommander who has modeled vertical antennas and shows that having shorter radials can also be effective. To add to this, I have 2 earth rods approx 1.5m under ground. I am not sure about the effect of the earth rods, but if you know maybe you can email me with your thoughts. and because I had extra wire I decided to tune 1x elevated radial along the fence. This combines multiple techniques that I have used before. Over the coming weeks and during CQ160 CW I will test this antenna and work on improvements for future.
I should also mention that each antenna goes to earth when not in use to avoid interactions between the two elements. As I repeat over and over, I am an experimenter, not an expert. Please feel free to email me your suggestions and comments… but for now 73 es CU on 160!
So what have I been up to since the last time I posted in this blog?… March saw me jet off to Togo with the EIDX group where we operated for 2 weeks as 5V7EI. The team consisted of 14 operators from 6 countries. Over the period of 2 weeks we made in excess of 50k QSO’s making one of the highest QSO numbers on any EIDXG DXpedition. A full report on this will be published soon.
Following my return from Togo I participated in CQ WPX SSB from the station of Nick G4FAL, I operated for close to 36 hrs using the call sign M7K, I made a little over 2600 QSO’s with a total Score over 6 million points as a single operator. I also participated in CQ WXP CW from M6T, again single operator making shy of 3000 QSO’s and over 6 million points again.

I paid a visit to Ham Radio in Friedrichshafen, where I saw old friends and met some new people who I hope to operate with in the future. I always find this events a great place to socialise, catch up, make new friendships and network with fellow DXers and contest operators. Here is a picture taken by Nigel G3TXF of me enjoying the company some friends.
In the coming months I will have some more DX trips. Firstly I will get a visit from my friend Phil DK6SP from Bavaria, and together we will travel to Ireland stopping in Dublin on the way to DX Feile hosted by the EIDX group on Aran Island (IOTA EU-006). There will be a Social event and a programme of talks for us to enjoy, as well as a station to activate the IOTA as EJ1D. More information can be found here > www.dxfeile.ie
And in October I will be heading for Cyprus where I will operate as 5B/M0SDV and P3F during the CQWW SSB contest, Many thanks to Bob 5B4AGN for hosting me at his home on the island. I’m sure there will be some fun pile ups to work whilst I am there.
As for further ahead only time will tell what I’ll get up to, No doubt planning for more DX and contest trips. Exploring the world and making many more ham radio friends along the way. Keep an eye here for my next update!
As we approach the festive season many companies are starting to slow down for the year. Here at United Radio we like to push through to bring you the very best and fastest service. However our postal carrier here in the UK, Royal Mail, start to slow their collections.
Last post for mail to arrive before Christmas is 18th December. After this time Mail posted is unlikely arrive before the 27th December. Therefore I will have a Close down period for 1 week between 20th – 27th December. This gives me time to spend time away from my desk and with my family through the festive period.
I would like to thank everyone for their support over the last year. And I wish you and your families all the best and Happy Holidays.
In the final 24 hours before I depart for Bonaire I am almost fully packed. I have 1 antenna to make for 30m to do a real effort on CW. Tonight I venture to the airport where I will stay in a hotel ready to depart first thing in the morning to Amsterdam, followed by a long haul flight to Bonaire.
I will be trying to give everyone the opportunity to work Bonaire. Especially the little guys! Skeds are OK by Appointment (Email me) Another reminder about the Live log, I have made this to reduce dupe’s in the same pile up. SWL reports are also welcome Via The SWL OQRS System
See you in the Pile ups!
A short update that I’ve been wanting to write for some time now. All QSL cards for YOTA, 7X5KBS, DM500RT, V31PS and other calls are now 100% up to date as of last week. Please expect to receive your QSL cards soon!
Remember, I provide a guarantee with all letters. If you have not received your QSL card, please email me within 2 months of the letter being posted and I will send a replacement free of charge.
Do you need a QSL manager? Well look no further. Click here for everything you need to know!
Philipp, DK6SP (20 years), and I, M0SDV, (17 years), will be QRV from Bonaire as PJ4/homecall from 16.03.2018 – 02.04.2018. Operation will take place at the QTH of PJ4DX.
We will try to be QRV from 160m through 6m focusing on WARC bands outside of the contest.
Modes will be mostly CW and SSB but also digital modes like RTTY or FT8 are planned. The activity also includes participation in the upcoming CQ WPX SSB 2018 contest. Operators will be DK6SP, M0SDV, PJ4DX, PJ4KY and PJ4NX. Category and contest call will be announced in time.
During our stay on Bonaire there is also a trip planned to another DXCC in the Caribbean. Please see Twitter for Live updates
QSLs will be via home calls for both operations.
We would like to say an enormous Thank you to Steve PJ4DX for loaning us his equipment and helping us along the way! We couldn’t have done it without you!
Also Thank you to DX Commander and G3TXQ Hexbeams for antenna loans!
