CCX 3cms - on or off - not CW

usuallyqrt <usuallyqrt@...>
 

CCX 3cms had a fault some time back where it would go off if the 70cm repeater was on. Easy to check if the 70cms is on and the beacon is off thats it. Or fire up the repeater and see if CCX goes off. Not seen anything reported that its been fixed. I dont hear CCX at ohm so unable to check this out myself. 73s John.

And not nearly as good as true Araldite which can still be bought on eBay!

When did Araldite become Evo-Stik ?
Same packaging at first sight, same colour packs. Just a name change and
the two tubes placed in the blister pack in opposing directions (and that's
weird)

Confusing us of advancing years ;-)

Hi Keith, CCX is on this morning but I think the power is much reduced
from normal (the site is just above me 4k distant) not reaching full scale on the meter here as usual 73 Graham G3VKV

Thanks Ken, I'll check when I go out /P on Sunday.

Re: [Moon] [Moon-Net] Agilent 346A and N9069A reading high?

Conrad Farlow <conrad@...>
 

I don't think so. That was merely one example of several preamps that I have that have been measured elsewhere by trustworthy individuals to have much better noise figures. I have a 346B noise head I am going to try that as well.

I was hoping that I was being stupid (I certainly have the capacity for it) and missing something basic.

Conrad

2.When I measure noise figure I see good results on the gain but the
noise figure seems high. For instance my HA8ET Extra 2 LNA reads about
1.4dB whereas I am pretty sure that it is much better than this.
it's all a lot simpler than long convoluted theories....

the pre amp is oscillating

3cm sked?

gm0icf <gm0icf@...>
 

With the area of high pressure sitting over the UK is anyone interested in a 3cm sked either tomorrow, Friday 19th or Saturday 20th afternoon/evening.
Locator is IO75OP.
cheers,
Bill.


Agilent 346A and N9069A reading high?

Conrad Farlow <conrad@...>
 

I have access to an Agilent 346A head with an N9069A noise figure measurement application running on an EXA series spectrum analyser. It seems to have number of issues.

1. After calibration the noise figure and gain are never truly zero, the noise figure normally reads -0.1 or similar and the gain will be -0.15 or thereabouts, these are just typical figures.

2.When I measure noise figure I see good results on the gain but the noise figure seems high. For instance my HA8ET Extra 2 LNA reads about 1.4dB whereas I am pretty sure that it is much better than this.

I have Tcold set to the temperature on the surface of the device as measured by a thermocouple. I have used some loss compensation before the device, I have generously allowed 0.1 dB for a high quality female-female N type.

Does anyone have any advice as to what is going wrong? I do have an 8970 that I could use for a reference check but it hasn't been switched on for a while, shocking I know.......

Bit puzzled..

Let's not go into the reasons as my blood pressure might not stand it, but I used to be a member many years ago, but am not now.

I did find a link to an email address to request an affiliated club be added, so I've sent a request.

Not sure how long these things take, but I'll keep going back to look for a few days before using the G-QRP Club option.

All,

Just a reminder that the closing date for the Ofcom 2.3 Ghz consultation process is approaching.

I believe that everyone, whether active on 2.3 Ghz or not should respond, as we need to show Ofcom that we value the spectrum we have access to.

If they do not see a large response, they will be more inclined when considering the future of other bands, such as 10 GHz, to take the approach of the authorities in Sweden and Australia and just remove our access to bands without consultation.

In order to encourage responses from the ATV community, who are particularly affected by the proposed changes, I have posted my own proposed responses on the BATC forum at http://www.batc.org.uk/forum/viewtopic.php?f=2&t=3176&start=10

Chris GW4DGU has also published his responses in the latest issue of Scatterpoint.

Thanks to the good work by Murray and others we do have a good relationship with our regulator in the UK and this is the opportunity for us all to show them how much we value the spectrum we have access to.

G100RSGB tomorrow

g4bao
 

The camb-hams will be qrv as G100RSGB tomorrow and Thursday. Operation on HF, 6 and 2m plus the rare chance to work the callsign on 1.3 and 10GHz. On 10GHz we just have a dish on a tripod so only have unobstructed takeoff from West through to North. I have already worked g4cbw with the system, so fine for working the UK. 360 degree takeoff on 1.3. Liase via KST.

Re: 24GHz, 47GHz, and 76-248GHz Contests next weekend, 21st July

Hi Daniel

You would need some exceptional tropo to work the UK on 24GHz from there. The IARU region 1 record on tropo is about 580km. Rainscatter might work, but it you don't often find intense thunderstorms over the sea.

I look forward to a 10GHz QSO soon.

Hello John et al,

I will be in the north of Germany from next Saturday for a week or so.
The QTH locator will be JO44IJ or thereabout with only water between me and the UK. The closest distance is just under 500kms (Norwich area). Given the lifted conditions predicted by the Hepburn Index Website for Sunday, I was wondering if it would make sense to take 24 GHz with me. My setup is just 300mW to a 30 cms diameter dish. I finished the station 2 weeks ago and have never made a QSO. It looks OK on the bench though.
I was planning to bring my 10 GHz setup, so I have the tripod and the other necessary gimmicks already there. But then again it's holidays in the first place and the car is pretty well packed.
I have no experience with sea ducting and I don't know if it will help on 24 GHz anyway where rising humidity would be rather disturbing, I guess.
The QTH would be either close to the beach or maybe on top of the dyke at 10m asl or so, depending on the tourist density and parking possibility. I need the car battery to power up the station.
I would appreciate to receive some comments before I go into negotiation with my fellow holiday makers.

P.S. I should be around on 10 GHz frequently. Look for me on KST. I have 14W and a 65cm dish.

Thanks John,

I've looked again and can't see anything that might be UKuG. The only other "UK" is the UK six metre group.

As I was using just 10W, and the G-QRP Club limit for SSB is 10W, I'll probably use that.

I wonder who you have to contact to get an affiliated club included on the list?

Another chance to work G100RSGB on 10GHz on Thursday

g4bao
 

At the last minute, I've decided to take some 10GHz /P equipment up to JO02CE with the G3PYE operation as G100RSGB. I may only be able to utilise the gear on the tripod which will mean I've got a limited take off mainly to the NW but I'll try and get a spot on Flossie's 40ft mast if we still have the coax and the power cable from Mull2012.
Operation will start from Thursday morning. Watch KST for more info.

1 Watt to a 45cm offset dish
