Very nice, it's coming together nicely. The standard size enclosure is a very nice thing, I also have a whole stack of equipment I built over the years. The little brass boxes make it very easy to solder stuff to, I like to use the commercially made ones from silver sheet metal.

Skaisti :) Tālāk jau var domāt par 10GHz SSB uztvērēju.

Hi Greg, may be you'll need to put an absortive material such as ferrite sponge in the 10GHz box to avoid sharp waveguide resonances

Yep!! We need to discover a cheap absorber

@@AllElectronicsChannel uhmmmm at 10ghz, water is an good absorber. isn't it? ;) no, Im just kidding. Some plastics, polymers and ceramics are very lossy at 10GHz. May be an interesting subject to investigate the tangent loss of materials with vna and cavity resonator

Yes! Currently the trippler delivery something near -10dBm

I think the numbers on the diagram dont match...107.2/16=6.7GHz therefore the output of VCO will be 31 X 107.2+6.7=3329.9GHz

Do you have AliExpress, Amazon, etc. affiliate links? We can support the channel that way too. Curious about that coax!

Good ideia!! I will create an affiliate link from aliexpress with the sellers I buy! The coax is rg402, also from aliexpress.

At frequencies above 1 GHz, the inside of the metal (copper, bronze or brass) case must also be coated with a thin layer of silver. Also, PCB tracks and conductors operating at frequencies above 1 GHz need to be coated with silver. To reduce conduction losses.

Thanks man! For FR4 the main losses are from the roughness of the copper to clad contact, so plating does not help much.. I don't remember who tested it, I think was Matjaz S53MV

@@AllElectronicsChannel The point here is not that it does not have a very strong effect, but the fact is that over time, oxide forms on the surface of the case and conductors made of copper and its alloys and it conducts microwave signals much worse, which pass only over the surface. But silver and silver oxide conduct microwave currents almost as well and allow you to get more stable parameters for a long time.

Thanks! The tracks are actually silver plated, hehehe. I used a silver plating solution. I did not silver plate the brass
