VK Logger Ham Radio Forum Archive

This is an interesting science experiment, so you might be interested in taking part. Feel free to share this info elsewhere HamSCI is looking for radio amateurs around the world to help collect propagation data during the December 14 eclipse. Data collection requires an HF radio connected to a comp...

Hi all, Second run interest is now north of 140 units so I've has some quotes returned from the manufacturers. The price of the horn & feed/coupler remains unchanged. The cost of the assembled & tested board has increase by $20 USD due to the lower quantity requested, to $148USD each. The co...

Hi all, I'd like to formally call for names of those who would be interested in a second run of the current model of the 122GHz transverter, to buy made boards, blank PCB's, horns etc. Please email me direct or via the 122GHz list with your requirements. *** PLEASE have the subject line contain &quo...

Hi all, Hilary, VK2AZ, has be quietly beavering away to bring us the next major update to vkspotter.com This is a significant update that brings new and enhanced functionality to the spotter. We now have chats for HF, 10m, 6m ,2&70, 23cm and above and the ability to turn chat off. We also can no...

Had quite a few on tonight, much fun had by all.
Best SSB contact between Brendan,VK2BRM and Darrell VK2BLS at 91km
I had a very easy JT65c contact with Darrell on 3.4Ghz

Gidday Tim, Thanks, just a tad bigger than the 122GHz kit I am looking forward to :-). 1 metre diameter dish, planning on 60 W, but, the exchange rate is making DB6NT devices much more expensive than I’m willing to pay. Sent from my iPad using Tapatalk Yeah..... 60w at 10GHz is generally many $$$$ ...

Testing the 150th VK3CV transverter board

Nice 10Ghz kit Peter.
How big is that dish ?
How much power are you going to feed it with?
cheers
Tim

And that sent me on a quest for a LNA for my rig, I coudn't find the 362LN, well not at a reasonable price but I did find a new Mini-Circuits ZX60-3800LN-S on Ebay for less money than a new 362. The IP3 & gain specs are a bit better than the 362 but with a similar NF of 0.9dB. Model Gain IP3 ZX6...

Just changing out the weird Band 3 connector on an EIP 588B frequency counter to an SMA. The old connector looks like and odd form of SMB but its not. Interestingly the newer EIPs and the C version come with an SMA in this position. Now I just need to find an external mixer or two for the higher ban...

Nice work Darrell!

I see a "Pre-amp" switch on there, what are you using as a pre-amp ?

Looks like I had better climb on the roof on the weekend to install a dish on the tower so I can point at you

cheers
Tim

Hi John,
Check you version, you may need to update to the latest for it to work again.

Thats what I found with mine

cheers
Tim

Tim, keep an eye out for old "Fluid Heads" that pop up on eBay etc. Pan/tilt heads that have reached their end-of-life for professional camera work, but are perfect for parabolic dish aiming. Hi Adam, I subscribed some time ago and have watched your video on the Miller heads and I've had ...

Now that my 3.4GHz transverter is complete I'm finally getting around to assembling a transverter for 10GHz :) A ZLPLL, MiniKits sequencer, and a miscellany of bits from an old Harris transceiver going inside a Jaycar HB5556 case. I'll have to think about how to mount it to a tripod since I have a c...

Hi all,

My transverter is all boxed up and ready to go. Switchable 2w/20w.

I just have to put an antenna on the tower and its QSO time

cheers

Tim

Hi all,

The problem with the measurement of the 3.4GHz yagi was me.

I had negated to calibrate out the N to SMA adapter I was using on the yagi!

Rerunning the test shows a return loss of about -28dB @ ~3398 MHz.

I'll redo my little video

cheers

Tim

Hi all,

I've just uploaded a video where I test the PCB yagi that comes with the transverter, unfortunately the result is not good!

Hi all,

I've just uploaded a video on how to program the SGlabs transverter to a different IF.

Hi Hayden, Was this easy to do Tim? I'm just in the process of removing my GARC panel from my 3.4 GHz system over to the SG Lab transverter. It will only accept a 430 MHz IF out of the box. Do you have details on reprogramming? Yes! :) - I've added pics with the instructions in the "info" ...

I got an SGlabs 3.4GHz transverter for Christmas and I've just reprogrammed its LO to match the IF I use for my transverters.
