I plan to be operating portable north of Bairnsdale on most bands between 6m and 10 GHz.

Great day. Worked -
VK4UH/P, VK4EA/P, VK4CZ/P and VK4CSD/P on 10 GHz
VK4UH/P and VK4CZ/P on 3398.1 plus one way with VK4CSD.
Also several contacts on 1296.1

I will be going to Clear Mountain QG62KQ with 1296, 3398 and 10368 MHz.

Receiving my test beacon I get a S9 signal when I first power up the panel. Once I have transmitter once , even just a short PTT, the signal goes down to S8. If I cycle the power it goes back up to S9. Any ideas?

Geoff VK4KJJ

I hope to participate.

Hopefully I will have my 3.4GHz panel finished by then as well so will be looking to try it out.

I will be operating from my normal spot at Clear Mountain on Saturday afternoon provided the weather is Ok

6m, 2m, 432,1296 and 10 GHz.

Stefan,

Absolutely you can use FM. The more people we get on uWaves the better.

There is also the VHF/UHF field day this weekend.

You are welcome to join me if I go portable - yet to be decided -. I normally go to Clear Mountain lookout.

Email me at VK4KJJ at WIA.ORG.AU

I will be operating 1296 and 10 GHz from home.

From the AMSAT UK site.

"Measurements made by Alan Biddle WA4SCA indicate the downlink is consistently 1.400 kHz low at 145.9786 MHz. Reports indicate the uplink may be 10 kHz low of nominal frequency – 435.170 MHz."

I will be operating from Clear Mountain on Saturday with 6m, 2m, 1296 and 10 GHz.

Very strong carrier on 145.8 on last pass but no modulation. It did allow me to check my Doppler corrections, so all was not waisted.

Damien,

I work at Airservices so I will ask around tomorrow if anyone still has a manual for an R40.

Dave, At my suggestion Adam has already included an option for slight frequency offsets for Digital modes called "Zero DF offset". For example VK4RBB on 432.440 you need to set your dial 1230 Hz low to get zero DF on JT4. But you are right a similar idea for CW beacons would be good. Geoff...

I had a good day, 3 contacts on 10 GHz and 6 on 1296. New PA on 1296 and 10 GHz seemed to work OK. I initially set up on the western side of Mt Mee at Somerset Lookout then moved to the East to Sellin Rd.

Looking forward to next microwave activity, 73 Geoff

After consulting some maps I am going to try a new site (for me) at Kluvers Lookout in D'Aguilar Range west of Dayboro. I will be operational on 2m, 1296 and 10 Ghz.

You may be aware the VK4RBB beacon has a "feature" when very occasionally there is no signal for a whole minute. To try to rectify this, a modification was made to the beacon this afternoon. Please report here if you notice the beacon is still missing minutes occasionally. If you do notice...

Adam,

Sorry for not getting back to you earlier. For the DF offset you need an extra digit so that you can enter -1230 for example.

Geoff VK4KJJ

I plan to be active on 1296 and 10 Ghz although I have not decided from where yet.

Adam, Your proposed implementation of a JT mode offset looks good. The zero DF offset needs a bit of a defination. I propose this----> It is the amount below the actual frequency you have to put your dial to get a report of zero Hertz for the DF value on the JT screen. So for VK4RBB that is on 432.4...

Adam, One additional thing to consider is the dial frequency you need to get zero DF on the JT4 screen. The way the VK4RBB beacon has been implemented there is a small frequency offset that you might not expect. If this offset is published it might be useful to folks particularly DX stations who are...
