Re: Re rain scatter program

The `tucnak` (multi-platform) logger incorporates a rainscatter mapping function which, in the recent version, highlights (probable) scatterpoints reporting 6-char locator (and much more besides).

Re: Re rain scatter program

there are a number of tools out there

TK5EP https://www.egloff.eu/rsmap/rsmap.php# is quite good. I haven't checked how up to date the radar data is.  it refreshes every 10 min

Uffe PA5DD did one in JavaScript that I modified a little but the original map data became inaccessible. I don't know if he updated  his, I didn't.  Check his web pages?

I just remembered that I could hear a continuous tone on 2320.913 which got weaker as I turned the dish away from FNM so it may be related.

noise genny

militaryoperator
 

The little noise genny from China (where else? but at least they deliver) has arrived and an initial try through my 9Cm filter gives a nice steep sided response. 

It was interesting to see the shape change as I adjusted one of the screws,  much easier when you can see the signal, hi. 

Really need to get a better speccy though, missed a 3.8Ghz one that went for less than £500 and one up to 8Ghz gets no reply to a question from the seller, go figure. 

I just need to box it up and make it easier to use, save dropping anything on it while it's on, and then I can give the filter a tweak.

Finally received it after a week of no post, their are all self isolating here apparently.

Will be on 10Ghz tomorrow, had a nice qso with G4ODA earlier today, thanks Keith.

Re: Milled boxes

The bulk buy order to RF Microwave has now been placed.

Once I have received the parts and repacked for onward UK shipment ( Royal Mail ) I will send individual e-mails those who have placed firm orders with me to advise them of the final cost and payment details. ( send nothing before then )

Hi Colin Ah yes the grain of salt SMD components, about 100years ago in the days when we had rallies I started to buy old LNBs to play with, so I know what mean about older technology. the only thing I found was that rally vendors wanted more for their old 'probably not working' LNBs that the cost of a new one! But it was quite educational..I even got one with flanged WG17 on it.

You are right Alan, any modern LNB will have a good amplifier at the front end, possibly with a better noise figure. I think the only real benefit of the Franco boards is that they are fairly old technology and therefore somewhat larger and easier to modify than some of the modern LNBs.

Well you can seam-solder the ground to the enclosure with those ! :-))  I always wondered what was so majik about milled ali boxes for microwaves.     Sour grapes ??   mabe

 

It might almose be cheaper to buy a current LNB (CPC?) and rip the pcb out replacing the chip if you can find a better one. There doeant look anything special about Franco's boards. I think I have seen examples on Peter's G3PHO web pages, from a few years back.

 

But waddereyeknow.....I only sell tin boxes :-))

I don’t think any of the boxes are specifically made for the preamps. 

That milled box is actually quite large.

Hello Mike,

 

Thank you for revealing yourself... Mark said you were in the Huddersfield area though QRZ suggests otherwise.

 

I don’t have 3cm up often however it isn’t too long a job to swap antennas as I reminded myself this afternoon. Drop me a line if you would like a test though others are also QRV, G4DBN and G3YJR etc.

Thanks are also due from me, for it is me that the 3cms loan system from Mark is destined for! And, of course, thanks to Mark!

I'm looking forward to giving it a go and will be making the short trip to Ilkley Moor once I've got the system all together to listen for some beacons and get used to it. Hopefully it won't be too long before I'm arranging to go up there with the intention of having a qso...

10 GHz experiments this evening

Neil Smith G4DBN
 

Things seemed a bit flat on 3cm this evening to the south and west, but after some co-ordination via Zello SHF Chat, I had an SSB contact with Adrian G4UVZ at 342 km in IO80 and a solid CW contact with Clive GW4MBS from his home location in IO71 at 288 km over a hugely unpromising path on 10 GHz.

I had a sniff of a signal from DB0GHZ an hour ago, but the only signal now is ON0VHF, about S3 from JO20HP. Nothing from any other EU beacons.

Thanks to Adrian and Clive for the tests, very pleased to make those contacts.  I guess Clive could have made it at 12 dB lower signal using Q65.  The signals were very stable and just had the usual scintillation of troposcatter.

Re: KST or Zello ?

Neil Smith G4DBN
 

I find Zello is most useful for talkback rather than asking for sked attempts, mainly because I use a headset and use Zello on my phone most of the time. It is good outside of contests when my pocket starts talking and I get to hear about some juicy propagation while I'm away from the radio.  If I remember, I fire up the Zello app on my logging PC during contests, which makes it a bit easier. The Windows version seems to work pretty well, but I have some amusing issues with audio input devices on my radio PC that cause some challenges. Works fine on my laptop though.

I hope to have it sorted soon by using a mixer on my headset and a separate microphone input for Zello.

KST is still the best tool for my way of working, I get so much other intel from it by watching what others are up to.  I need a sked queue facility though, and a better way to integrate the multiple-path aircraft scatter alerts from Airscout.

Just remember that you can flip into person-to-person mode on Zello so you don't bung up the shared channel if you are doing detailed adjustments and fiddling.  I usually forget to flip back, but it is neighbourly to leave the main chat free if you are using it for classical talkback.

Another good tip is that in UKuG contests, you can use Zello as the return channel for one-way contacts if you can hear the other op but they can't hear you, and both claim half points, so long as all exchanges from them are solely over the radio.

I don't know if I'll be able to get on for the contest, but I'll be on KST and Zello if I do get on the air.

The fun starts on Sunday seeing how it works in practice with lots of people about & "meep, meep" also popping up around my ears. At least it looks as if there is an "engaged" button on Zello, which might help reassure people that they are not just being ignored!
