Views on changes to Portuguese Licensing system

Image
I was alarmed to hear this news on the weekly RSGB news broadcast. For those that can’t be bothered clicking the link I’ll summarise: they are introducing a new licensing system in Portugal whereby Foundation licensees have 5 years to upgrade to an intermediate license or they lose it. I think this is incredibly short sighted of the Portuguese licensing people. As an M3 who’s had her license for 3 years if they introduced this ruling here in the UK (which some G stations have recently been arguing for in the letters section of Radcom, much to my annoyance) this would mark the end of my hobby. In fact you’d probably hear me on CB frequencies instead - I’d be the only operator not swearing their head off. I’ll say it loud and clear for all to read: I have absolutely no intention of getting an intermediate licence. Why you may ask? Well my Foundation licence gives me everything I need, I can operate 10 watts. I have the shop bought Yaesu FT-847 plugged into the shop bought length of co

Welding Wire Dual band Satellite Yagi Project.

Image
After seeing the pictures sent by Cyril F4FUL of his homemade dual band Arrow style Satellite Yagi, I finished off the prototype model I had been building during the week. The newly finished off home brew Yagi antenna comprises of 4 X 144-146 MHz Elements & 8 X 432-435 MHz Elements. The Elements are made from 3.0 mm Welding Rod and the boom is a wooden broom handle. The Elements are gently tapped into 2.5mm (tight fitting) drilled holes in the boom. I used two lengths of 50 ohms Coax soldered straight on to each of the two bands driven folded dipole element. Finished and all tuned up and ready to assemble to the mast. I used a PVC mount which connected to the boom acting as a bush and allowed simple elevation adjustment locked off with a 6mm bolt. Set at 30 Degrees Elevation looking southerly into this evenings sky. Now it will be a case of testing as I have got some nice lengths of 6mm ally bar which is waiting to become either extra elements for the IOIo or a Cross Axis dual

Spring equinox and its effect on propagation

For all of you living in the Northern Hemisphere today is a great day. Today the Spring Equinox (or Vernal Equinox) is upon us, this is great as it hails goodbye to winter and officially means the start of Spring. At 11:44 UTC the sun crossed over the Earth’s equator which means longer hours of sunlight for all of us up North! Thanks to the Earth’s tilt 23.4 degree tilt we will now be getting more of the Sun’s rays increasing the temperature (hopefully) and signalling the start of Summer. The Spring equinox also has a marked effect on propagation. We will now be having longer hours of sunlight. These longer hours mean the sun will be increasing the energy in the ionosphere more than during the winter. You may have noticed propagation improving over the last few weeks, this is due to the Spring equinox. The Vernal equinox is a particularly good time for HF propagation as on the first day of spring the length of the day and night in both the Northern and Southern hemispheres will be

Homebrew Dual Band Yagi

Image
I have recently been in qso via the Internet with Cyril F4FUL Who Is located in the French Alps, locator square JN36EH. Cyril had recently built an IOIo Satellite antenna and was interested in building a antenna similar to the ARROW antenna He saw me using in one of last years videos. The tests showed that the Arrow does out perform the IOIo. I agreed signal reports and comparisons with Cyril, Who then said he was on his way in building one and would keep in touch. I was interested to see what Cyril - F4FUL would come up with? Here is the result: The F4FUL, Home Brew, Dual Band Arrow like Yagi. 4 elements VHF and 10 elements UHF. Thanks Cyril F4FUL, for your images. 73 Good DX! Thanks to Cyril's inspiration, I also came across some specs for a simple antenna build similar to the Arrow. I have almost completed one and have yet to add the feeder to complete the first attempt. I have built this "prototype" antenna from 2.5mm wire and a broom handlel I will post det

Mobile DXing working JO7CVU & 6Y/WE9V/Portable

Two Great Contacts worked from my Mobile HF Station - JO7CVU from N.JAPAN and 6Y/WE9V Portable from JAMAICA. My Location was close by to my Home QTH up at 1000ft on Baildon Moor, W.Yorkshire, N.ENGLAND The first QSO was JO7CVU worked on my way to work at 08.20 utc. The second QSO was 6Y/WE9V portable worked on my return journey at 17.00 utc. 73, Thanks for all radio contacts & thanks for watching!

Early morning Mobile Dx into North Japan

Image
This morning I was fortunate to hear some big signals coming through on my mobile work bound journey. I heard VK3MO from Austrailia with a 5/9 just as he was closing down. I then tuned up the band (20M) and came across Kentaro - JO7CVU from Sendai City, North Japan. Ken was coming through 5/8 and peaked at 5/9, I gave Ken a quick call from the mobile FT-857 and Maldol 20M antenna and too my great surprise Ken - JO7CVU came straight back to me and gave me a 5/6 report. I managed to sweet talk Louise M3TLL to video the contact with Ken, I should be uploading it this evening. This definately was a great copy from my mobile running 50watts in to North Japan, I will be listening out for early morning DX tomorrow.

Contesting

Image
 Last week and this week I decided to try and work some stations during Tuesday nights RSGB VHF Contest. The Contests are held weekly on Tuesday evenings and Cover five VHF Bands. I have operated on two of the five Contest bands 144MHZ and 433MHZ. Below is the table found at the RSGB Contest Committee Site explaining what band is used and the operating times of each Tuesday's evening Contest. Also the previous month - January's results can be seen via the Results links. Every 1st Tuesday 2000-2230 (Local) 144MHz UK Activity Contest and Club Championship AO   AR QTH Locators ( M2 ) , Activity contest ( S8 ) , Club Championship ( S9 ) Every 2nd Tuesday 2000-2230 (Local) 432MHz UKAC AO   AR QTH Locators ( M2 ) , Activity contest ( S8 ) , Club Championship ( S9 ) Every 3rd Tuesday 2000-2230 (Local) UHF UKAC AO   AR QTH Locators ( M2 ) , Activity contest ( S8 ) , Club Championship ( S9 ) Every 4th Tuesday 2000-2230 (Local) 50MHz UKAC AO   AR QTH Locators ( M2 ) , Activity contes

The 2E0HTS Portable Antenna Mast Mount

Image
Since I sold my Toyota Rav 4 I haven't had the means of setting up the spare Hustler 6 BTV - Base Station Multi Banded HF Vertical. I used the tow bar fixing which I had made and had some excellent results with that one, not to mention the 14,411 YouTube Views on the Video I made using it. With the first Mast Mount Creating so much attention the pressure was on to come up with another Mast Mount strong enough to bear the Hustler's 6 Band Load in windy but typical Yorkshire conditions. I had seen some wheel bearing Mast Mounts on eBay , so I decided to make up my own version which worked out well. Materials used: 3mm Mild Steel Plate, Cut at 260mm wide X 550mm long. 25mm X 25mm X 3mm Angle Iron (L), Two pieces cut to a length of 550mm. 70mm X 70mm X 3mm plate square, Two pieces cut in half into a triangle to become gusset supports. 200mm diameter 3mm plate, cut plate into a half circle then drill 12, 6mm holes to be used as radial mounts. 38mm diameter mild steel bar, 600

Last night before pulling the plug

Last night before pulling the plug, I had a last radio contact to make which was with M0OGY - Dave in North Lincolnshire. I recently became friends with Dave - M0OGY, via the ever growing YouTube Community of "Hams" and "SWLs" that have some very interesting Amateur radio videos on YouTube. Dave and I recently worked each other for the first time last week on 2M SSB . Last nights QSO was worked on 80m a totally different band, which worked much better with bigger and louder signals sent and received. Dave's Shack looks impressive and can be seen in his video as he works with a Yaesu FT-1000 Delta, G5RV and 100 Watts. I used My Yaesu FT-767 GX, Heil GoldLine Mic, G5RV, and 50 Watts to make the contact with Dave. Tnx Dave. It is a useful tool to be able to use YouTube as a means of checking how your station is sounding at the other end of the QSO. I will slightly back down the ALC after hearing myself on Dave - M0OGY's Video. Watch Dave's YouTube
