Don’t think they do them anymore ....they do this programble oscillator which can also be used as a beacon keyer

vhf design in Ukraine also do a similar programble osilator ....but a lot cheaper 😀

Does DB6NT still do these x96 multipliers?, cant find them on his site

I use 4 of the DEMI boards (fed by a 4-way splitter) to distribute the 10MHz from a GPSDO to all my kit. Very happy with them!

I already have one 4 port and one 8-port in use.  The 8-port was his first production upgrade board to turn a 4 into an 8.  They are by no means perfect, there is some port interaction and no transformer isolation.  When I boot my HP 8562A, it sends an output on the 10MHz port for a short time, which really messes up some of the other kit else connected to the same HUP box.

At this exact time I'm building a HUPrf e-field receive preamp and bias-tee kit.  I have seven more of those to build for a club project.

Re: hybrid combiner

SAM JEWELL
 

Thanks Andy,
I did wonder, afterwards, if that is what you were doing.
Although the hybrid adds a few tenths of a dB to the noise figure, as excess loss over the basic 3dB/port, the reduced size of the feed significantly reduces aperture blockage on smaller dishes, leading to better sun/cold sky (at least it did on mine!).
I can certainly recommend the FXLabs hybrid for this purpose. If you need to handle significantly more power than 200W, then a laser cut air stripline hybrid might be better than the FXLabs (possibly triplate).

Hi Sam,

Yes it is for a FHZ patch. The aim is to set it up as per his ppt presentation with two LNA’s, two hybrids and two SSPA’s.  For now just looking at getting RX up and running with two LNA’s one on each port before feeding into hybrid.

Ah, I see that is for combining two LNAs. Not sure about that one, then.

Probably not an ‘FHZ feed involved.

Intrigued why combining two LNAs?

Re: 3.4GHz transverter??

Tim, VK2XAX
 

Hi all,

I've taken some pictures of the SG labs 3.4GHz transverter and put them in my photo share. Scroll to the end of the page to see them.

You can find them here...

https://photos.app.goo.gl/YZscxrT5ZRtYHUKAA

I've also made a couple of quick videos testing the transmit and receive abilities of the unit.

You can find those here...

All devices have been dispatched (or will be tomorrow morning)  to those who requested them and sent the money.
Wish I'd bought a couple more chips - just one left for myself;  only need one, but would like to have kept another on the shelf for the future.
 
Note to self / others.  When buying in bulk to pass on, always get twice as many as requests for.

If you don't mind a bit of construction, I have  lengths of sage wire that can be cut to length and will make a good cheap low power (maybe 10W) 3dB coupler
(sage wire is rather like normal 141 size coax but with 2 cores twisted together)
If you are interested I'll send some details..  The cable is in short lengths   not long enough to make couplers for 432 but can be cut for higher bands

Re: hybrid combiner

Andy,
If that is for use with the popular SM6FHZ patch feed, the FXLabs 1-2GHz hybrid is popular. Used by several of us, with that feed, on 23cm EME? It is good for 200W, at least.
If you have trouble finding one, let me know.
They have appeared on EBay etc. Not expensive.
