As for I am a G8 therefore I am better than you. There are many far less in years than me that could jump over my head in many ways! I was always told Respect is earned and shound not be given! Even when I got my GW8 call many said OK when you going to get a real call and do your CW? So the them and us syndrome has always as long as I am aware been there!

M6SPW, maybe it would be a good idea if you want to discuss how poor activity/reception is to Rochdale or some other spot 30 miles away, on verticals you could start another dedicated thread, and let constructive comments on the national contests continue undisturbed.


Yes fair comment about starting another thread,but at least my comments we not snide and uncalled for refering to me as
"three sheets to the wind, a band transient and enjoying baiting you."
I will let the tread get back ontopic now.

So.....getting back to the original thread I found Tuesdays UKAC hard work.

Multipliers were up and it was good to work IO84 IO72 and IN95 but contacts were down, along with signals.
Either Ive blown my masthead preamp up for the umpteenth time or conditions from IO80 to everywhere else were rubbish,and I think it was probably the latter.

I didnt find anyone in GU or GJ this time,and even more amazingly didnt work a single PA...even Tony ASD was weaker than normal.
In the March session I had a horrendous noise for the first hour of the contest and still managed to work more stations than in Tuesdays session.
Lets hope Mays session brings a massive opening to EA8 that only extends to IO80 :-)

Ever hopeful

Post Re: 144MHz UKAC reminder
My reason for starting the UKAC reminders was to, hopefully, encourage people to take part and, from their observations, gain a better appreciation of what is "normal" on these bands.
Hopefully it will encourage some to spend more time on the higher bands.

The reason for the "reports" after the contest are to give a feel for what is possible with a station in an average location with reasonable equipment but not high power and multi yagi arrays. :)

It's not really about what is, or is not, on any particular band outside the contests.
After all, even though I can monitor 5 bands at the same time here, I can only transmit on one band at a time. :D

So, today for instance, around lunchtime there were half a dozen stations on 2M SSB.
G0MRL was the closest the rest were in the likes of High Wycombe, London area and Lincoln.
I did not keep a record of them as I've worked them all before and none could be considered as DX.
I did not call any of them.

In addition 6M and 4M opened up so I called CQ on 4M looking for CT stations as there are still some squares I need down there.
At the same time I was monitoring 6M.
There were some very strong stations from CT and EA and Ronald, ZB3B was buried under an avalanche of calling stations by the sound of it. :D
I worked a couple of CTs and EAs in the hope that IM69 and IM79 would turn up.
No joy. :(

I did, however, give a station in Ledbury a call, on 2M, at tea time as he seemed to have hit a lull in activity. :(

Generally speaking I spend a lot of time monitoring beacons as opposed to chatting.

I did put some CQ calls out on 2M this morning which were met with someone whistling. :?

Obviously I didn't QRZ the whistle. :lol:
Goodness knows what that was about but, no callsign no acknowledgment, as far as I'm concerned.

Back to the main thread. :D
Besides the copying stations through the locals difficulties the band seemed a bit strange.
Signals were unstable and some paths, G4RRA for instance, were down on normal.

I noticed today that when 4M and 6M opened the 2M and 70cm Dutch beacons (PI7CIS) along with the 23cm beacon (GB3MHL) were all normal strength but, as 6&4M faded, they came up in strength.

This evening the QSOs with both G8ZVZ and 2E0NEY were exhibiting vicious QSB.

Cheers

Tony

maybe the high pressure over the uk this weekend will help propagation.

Hepburn has been looking interesting for the next few days but, unfortunately, the higher intensity is to the West of the UK.
Not a lot of land that way!

Just a bit of movement could catch Spain.

We'll have to wait and see. :D

Conditions are odd tonight.

Working G1KPS, Canvey Island, on 2M our signals were all over the place.
59 one minute and, virtually, down to the noise next. :?
He is around 300km away and at sea level but, usually a much more stable path.

Cheers

Tony

Now please tell me about the theory of a zl special i have read all about them but i still don't understand how it works.
your thoughts?

If you can find an explanation then please explain to me. :D

I did some experiments many years ago and the figures claimed never seemed to add up when doing direct comparisons with conventional Yagis.

I've never seen any calculations that made sense or Eznec plots.

If the performed the way they are supposed to then the leading contest stations would be using them but, guess what, out of 130 claimed scores for the March 2M UKAC there are just 2 ZLs and both well down the list.

So I'm waiting for evidence. :D

What prompted the question?

Cheers

Tony

Post Re:ZL SPECIAL
Hi tony.
what promted this question was in 2008 i was up winter hill with my 4 ele yagi and somebody had a 7 ele ZL about 50ft away from me and we were conducting tests and my antenna was better on rx and tx same power in fact same radio, upon returning home i did some research and found that the gain figures quoted was in fact the same as mine 7 DBd i cannot find anything on the net to tell me how this should be or even why.
and also people have commented in the past how poor they are and like you said about ukac list.
i was just curious....
i was not impressed that night with it.

M******** quote 11.5 dBd for their 7ele ZL, there is no information as to polar pattern or F/B.
That makes it the same as an 11ele Tonna which is 14ft long.
The ZL is 5ft long!!!!
If it were true would anyone be using conventional Yagis?

My tests were done against a 9ele Tonna, 10.8 ft long and , reputedly, 10.2dBd.

The Tonna proved to be better.

The 12ele ZL is quoted as having 14dBd gain and is , about 10.5 ft long.

If that is true it is the same as a 17ele M2, which is 33ft boom length and 1.5dBd more than my 19.5ft long 12ele M2.

If I could trust the figures I'd buy one tomorrow. :lol:

I keep trying to find information with any meaning but, so far, I have failed.

If you check the trustworthy antenna sites, M2, Vine, G0KSC, YU7EF etc. they all tell the same story.
More gain means more length.
Note. Not necessarily more elements.

Cheers

Tony

I assume you don't mean in the contest as, I thought, you were using a vertical?

Whose 4ele is it or is it home made?

I use a modified 9ele Tonna for portable or a halo for casual use. :D

I've been trying to find info on the ZL for a long time.

All to no avail.

Sorry if it looked like a swear word.
I'll say no more. :lol: :lol:

Cheers

Tony

indeed, but i ended up throwing it in the bin due to the fact that i bent the boom by standing on it.
and the hands now don't let me do that sort of building infact i can now no longer solder a plug on coax these days.
but i have now bought a diamond 5 ele for home use soon and i have a 9 ele tonna portable beam to use which i was going to put up on tuesday but the weather put me off, these days i am a fair weather operator hi hi.
