Re: How much loss will this 3cm feed have ?

Steve G4HTZ
 

Ok ...I have told someone in the past they were transmitting on wrong polarisation due to be confused re waveguide ....I'm no expert on these things ...still got to connect my DB6NT G4 and 10w amp up at some point .
Good luck on 10ghz

Thanks, Steve,

But yes I will have to correct you, the feed has a twist :)

Thanks Andy,

The Right angle is a "C", but I presume it's has just as much loss as an "N".

Well if I am going to have to make a coax transition with a "SMA" or "N" should I be worried about the WG adapters ?

Oh yes so it is.
That will even swamp the discontinuity-loss of a right angle N

The dish has the threaded WG connector and I have had to use two adapters to get it to match the WG Transition, which has a "C" connector. I have had to convert to "N" with adapters.
Would a homemade coax to WG transition with the correct flange and a small coax pigtail be better ?

Next question does anyone have a suitable flange in WG16 that suits the dish, that I can use to make a "N" or SMA transition with. (Sorry I dont know the name of the flange, but it the one on the Dish Sanders maybe ?)

YES

Sharp right angle N adapters do not behave themselves at 10GHz - there's a nasty mismatch in there.   You'd do better to replace it with a semi-rigid coax with, ideally, N connectors or even SMA with N adapters.

When we used a sharp right angle at 12GHz for th GB3SCK beacon, there was something like 20dB signal loss.   I don't recall measuring at 10GHz, but certainly wouldn't trust it above around 6GHz

Re: Looking for 3cm's contacts this Friday evening from IO84

Nick Gregory G0HIK
 

Many Thanks Denis for my first narrow band 3cm's contact this evening.

Hopefully I will make it with the ops soon.

On Sunday I will be operating from another location which is several 100's of feet higher, so it maybe worth another try.

Activity List for (whatever]. Use for a subgroup perhaps?

Andy G4JNT
 

I wonder if there is any advantage to be had for creating a subgroup for activity listing?     SO long as everyone posts correctly, all activity will be clustered together, albeit viewable to all, so searching and collating for each event is made easier

The next in the summer season of UKuG 5.7 and 10GHz events takes place
next Sunday 25th August, from 0700 to 1900 clock time (0600-1800 GMT).
Entrants can operate for a maximum of 8 hours during that period.

This session coincides with the French F8TD Microwave Contest, so there
should be stations to try with across the channel.

I will compile an activity list from inputs received by close of play
Friday 23rd August. Please send details of your planned activity in the
usual format:

Re: Tuesday night 23cms

Good to work you on Tuesday – always nice to get a new call in the contest log. Yes, conditions were not great, so you can certainly look forward to improvements. Your 67 ele yagi is highly directional (I’m sure you know that already!) and you’ll need to be really active with the rotator.

 

What I am sure you will find after a few contests, is that you will gain a mental database of calls and locations, along with a realisation of which paths are likely to work, and this will help you to raise the contact rate. In addition, as a regular entrant, other ops will be looking for you.

 

100w and a 67 ele is a decent set-up, and you have the potential for some long distance QSO’s by aircraft scatter – take a look at “Airscout” and play with the software. There’s hours of fun there, with or without a contest.

 

Regards

Umm -  what a surprise I had on Tuesday!

 

I have not been active for a couple of years and after a rebuild of the of the station I Thought (?) that 100 W into 67 Ele with DDK preamp would net a good few contacts. 

 

Observations:

 

Just prior to 20:00 copied two PA stations and one station on the IOW. 

So despite being in a “hole”  50 M ASL with local surrounding ground rising to 80 M ASL I expected an interesting evening.

 

Of course  after 20:00 no sign of the PA stations and no signal from IOW.

 

After 2 hours I noted a /P station giving a report of 70 QSOs – and I was 9 !  Others in IO83 were doing better than me.

 

I did work stations  in IO  and JO with broadly reciprocal similar signal reports so my kit appears to be matched (RX v TX).

 

I did notice that conditions were not good (Martelsham well down on normal).

 

Though as has been asked/ said on many occasions those of you who “in the south” Please look North after you have worked  F, DL, ON, PA ect.

 

This is not a whinge just that some of us in the NW and Midlands would appreciate a couple of QSOs more.

 

Cheers

Simon

Activity may also have increased because because of the IC-9700 becoming available.
I am back on the band for the first time since the 1980s due to my purchase of the 9700.
Just need to get the antenna outside rather than in the loft.

Hello Adrian,
Now that I have switched my Zello on I can see you in the list there. 
I did once hear the beacon near you at 599 in early June. The rest of the time it has been just about audible in the noise at 419 or less .I understand the problems in my direction, so can call you on zello if the beacon comes up a bit.

Hi Simon,

Good to work you on Tuesday evening.  I experienced similar conditions and could not receive Martlesham although it occasionally comes out of the noise here.  My location is somewhat higher than yours but I think that trees some 200m away affect my signals - may have to increase the height of the antenna or move !!.
