Thanks for watching. I get excited just hearing my own beacon 200 feet away on this band! When I get this on the tower I will put the little mini-beacon at a site 5.6 miles away and see how that goes. It will have to shoot through a building and some trees which are very lossy but even so I am sure I will hear it fine at that distance.
I have a system a bit like this, though I used two cables, one for DC/618MHz and one for the 25MHz. I used a two output LNB that I modified myself, and a simple canned 25MHz DIL oscillator in the shack. Much improved temperature stability over the LNB alone, but not as good as GPS control, of course. I am using the LNB without a dish, so the performance is, of course not that good, but a beacon about 26km away, behind some hills, has been audible most of the time, sometimes with rain scatter enhancement, sometimes byt what I think as troposcatter. Good to see your thorough test, and I look forward to seeing your further progress. Yes, I am in the process of getting some 10GHz up and running, too. At the moment it is used, one for QO-100 downlink, and occasionally another for monitoring of the local beacon. Vy 73 de OZ9QV, Jan
Hello Jan. Thanks for sharing information about your project. It is nice to hear from others who are working along similar lines. I used two cables last year when I was doing EME reception experiments, but the dish was close to my house then. Now it goes on a tower which requires about 110m of cable, with 75m of that directly buried. I have only one spare cable going to the tower so I have to use it for everything. Before I do a full RX/RX station I will need to add more cables to that tower. It is a big and expensive job. I hope can I hear something with this RX setup. The nearest 10 GHz capable station is 280 km away, nearest beacon is 315 km. I hope with rain scatter I can have success.
Yes, that is a valid concern. Once I get both units mounted to a metal plate and into the box they will be pretty safe. There is a heavy solder lug soldered to the coax outer and the ground stud on the triplexer that should take much of the stress if it does get bumped.
Thanks again for taking us along with this journey. Very informative. I hope this rain stops soon! Have a great weekend and 73's!

I'd be afraid that if nudged the hard line into the DC feed thru on the triplexer could break because of its rigidity. Otherwise, pretty cool.

@@n1bug Cool.
