Paul,

Have a look at my re-write;  http://kst2you.bss.design/    I think you will like the map page, and the filter by distance is going to be put in place in the chat.  I still have a lot to do, but I think you will get the idea.

 - Sender or receiver of the message must be located x km or less distant from me

- Sender or receiver of the message must be located in a particular region (eg, if I was based in the north of England it might be England, Scotland, Germany, Netherlands).
or
 - Sender or receiver must be found in a list of stations I want to monitor

etc.  Maybe KST2me already can do some or all of this?

4. The ability to quickly know baring and distance from a target station is important.  Pity it scrolls off the screen so fast at busy times.  Those messages (server messages?) should appear in a separate window.

Just my thoughts.

Have a look at the http://kst2you.bss.design/     it uses websockets, so will work on any browser or phone,  the messaging layer was my next "thing to do" ... specifically, I wanted to have the option to ignore chit-chat from stations far too far away to be of any interest ... and provide "threaded" messages so when you have a popup window for one conversation, you only see the stuff relating to that conversation and not all the other crud scrolling past.

If you want to fork it, I'll stick it on GitHub.

What is the absolute minimum capability you are likely to want from KST ?
As far as I can tell this is all really needed for uWave operation :
1)  The ability to send a message with a specified preamble (eg a callsign) 
2)  An audio alert when a message arrives with a specified set of just a few preambles, including your callsign.

No server messages, no bells and whistles.  Just a basic message and and alert facility.
If you want all the extra you can use KST2Me, but a few have commented even that prog is over complicated and having to obtain keys shouldn't be required.

Just wondering, as it's dead-simple to write a TCP server; just few lines of code and parsing of a few strings.  You'll require a KST login for each callsign, of course, but that's all.

Re: Sun noise on 3 cms

Dominique Dehays
 

Hi Keith ,

1st question :

In tropo configuration , what is the measured difference on noise with power on and off.U need it to be something like 20db to be sure your transverter dominates the global noise figure.

Objet : [UKMicrowaves] Sun noise on 3 cms

I did something I've never done before while taking sun noise measurements on my new 2.4 mtr dish.
I had a sun reading on my chinese powermeter at 144 mhz of -52 db, and I accidently switched the power off the transverter .
The reading was -66 db, a difference of 14 db.
When pointing at true cold sky I had a reading of -58 db.
I've never played with anything bigger than a 1.2 mtr dish before, and usually use a 770 mm dish, where my readings average 5.7 db difference.
So cold sky to sun a difference of 6 db, nowhere near what I had hoped for.
Question is what makes up the difference of 8 db between sun noise and no noise ( power off), surely not cosmic  or background noise.
I've never tried or noticed this before and I'm curious what I'm hearing or not hearing :)
Cheers
Keith

Mine has sounded like that for several years, but it still goes on.
I'm intending to replace the controller with an all electroinc unit at
some point - as I have with my Yaesu RC-400.

Noise temperature of the front end multiplied by the overall conversion gain of the transverter signal chain.

Daiwa Rotator update- success!

John E. Beech
 

Hi All,
Having retrieved the DC7011 Round Controller ( why is it called that?) from the clubhouse I replaced the 6 way cable and it was as dead as a door nail. SO I took the lid off & replaced the internal fuse and it is now all working, including the dial read out. The servo mechanism in the controller sounds a bit clunky & erratic so I lubricated the gears, but I can live with that. It seems to be reasonably accurate ( + or - a bout 2 deg), both the rotator and the indicator stop on South when turning clockwise; the indicator stops on South when turning anticlockwise but the rotator runs on for a few seconds or about 10 deg past South before stopping. It is also possible to rotate it n one degree increments with short pushes on the controll switches. This is all with out any load/aerial on the rotator. So a successful afternoon & no need to strip the thing down.
All I need to do no is to re-engineer my mount to take this rotator before the week ends activities. Thanks agin to all those who supplied information on this beast.

de John G8SEQ
PS. I didn't bother trying to retrieve the 6 way cable from the installation at the club house (too much like hard work); I suspect the fault was there. It had a D-type connector for ease of dismantling after every club night & I'm guessing a wire has been pulled off in the plug.


Re: QO100 This Thursday

A great activation today. The weather was a bit rough initially, but the rain eased and the wind backed off by the end.

All Summit operators managed to work each other as well as a few other stations.

Hopefully I'll be out again next week.

Daiwa Rotator update

John E. Beech
 

Hi All,
Thanks to all of you that replied. I now have the information I require to sort the rotator. From measurements I've made, I think the rotator & its pot are OK. I think the fault maybe a break in the multicore cable, but I can't be sure until I get hold of the controller & cable. It is locked in a cupboard at the club house, which I don't have immediate access to.

Subject: [UKMicrowaves] Looking to test my 23cm setup
 

I have recently got my 23cm setup improved with a masthead box containing a G4BAO power amp and a G4DDK VLNA.

All I need now is to make some QSOs, however I can only operate from a remote site about a mile from my home QTH. Unfortunately there isn't currently room for a 2m antenna on the mast at the same time (A job to sort, admittedly) So I am calling random CQ directly on 23cm with no reply as yet and I'm getting bored of sitting around! So, looking to setup a sked or two tomorrow afternoon/evening. (02/07/2020). 

Take off from here is limited to anything west of a line drawn roughly between Barrow-in-Furness and just west of London due to a big thing called Black Combe, although always up for a challenge. I am located in IO84 so Lancashire/Wirral/GD/NI/EI perhaps GW? Perhaps even western GM land? etc, etc.

Would be wonderful to get a signal report on TX prior to doing a check log on VHF NFD

Thanks

Been a while since I took mine apart, though I might do so again shortly as it has jammed and recently been replaced.
Can be messy and if you open it up the wrong way the ball bearings will go everywhere so best be prepared.
Mine has got limit switches and I recall it was a bit of fun reassembling it so that they behaved whilst getting the indicator in the correct position.
Guess if you mark the case as you split it so that you put things together readily aligned that shouldn't be a problem but I repainted mine as well as fitting new bearings and pot so wasn't an option for me.

Thumbs up for Hammerite and its special metal primer - no corrosion on it after 10 years up in the elements and the stainless hardware was easily undone, unlike the original paint and bolts supplied from Japan.

Good luck
