Hi all! What schemes are available for someone who only has a funcube dongle? It tops out at 1700 MHz. I am thinking hetrodyining using a brick and a double balanced mixer. Block down converter is another option. Any other options on the cheep side? Norm n3ykf
Norm, You could start with the 5.1 GHz DRO in an old C Band LNB for the LO. Add an LNA IC, and Mixer. Use the IF section in the C Band LNB to cover cable loss.

Art, How do I recognize the Dielectric Resonance Oscillator? Where might I get one of these units? Where, how and with what do I plumb the rf with? Suggestion on parts re the lna ic and I assume a mixer ic? Wonder about the limit of dead bug construction at GHz? What methods might one use? I assume microstripline transmission lines.. No trips to AES, HRO or Skycraft here.. 73 de Norm n3ykf

Hi Norm, N3YFK
You need the book " The ARRL UHF/MICROWAVE Experimenters Manual ARRL Order No 3126 and ISBN 0-87259-312-6
And also:
The ARRL UHF/Microwave Project Manual ARRL Order No 4491 and ISBN 0-87259-449-1
The latter contains the contruction of : "A Single-Board, No-Tune Transverter for 5760 MHz"
The article written by Rick Campbell, KK7B contains all PCB plains and a list of material needed for it.
I hope this helps

Hi Domenico, I saw your post I also suggest these:
http://www.w1ghz.org/QEX/A_Single-board_Transverter_for_5760_MHz.pdf
F6BVA transverter : http://f6bva.pagesperso-orange.fr/La%20Technique.htm

Norm, The LNB units are used on the C Band Satellite TV Receiving Dishes ( the ones that are 8 to 15 ' in diameter). The DRO is a ceramic piece glued to the PCB with a metal case around it and a adjustment screw. Some are fixed in a metal can. The Mixer is used for 3.7 to 4.2 GHz Y may be able move it up to 5.8 GHz. The LNA may be able to go there as well. The ARRL and THE RSGB have several books on making things in this band. A lot of surplus equipment at sites is being changed out for new, and you might find something that can be tuned down in frequency from the 6 GHz band. Mini-circuits has several Low Noise amplifiers and mixers that can be used. Suggest you check out their web site. Try to fine some Amateur Radio Microwave Activity in your area. Most of us will spend time helping others to "get on the air"
Good Luck, Art, KC6UQH http://www.minicircuits.com/homepage/homepage.html Good luck with the project -----Original Message----- From: Lizeth Norman [mailto:[email protected]] Sent: Sunday, November 11, 2012 10:04 PM To: [email protected] Cc: [email protected] Subject: Re: [amsat-bb] receiving 5.8 GHz

Hi all! It sounds like two different schools of thought are at work here.
One is build it. Definitely cheep. Recreating a microwave receiver with a final if that the Dongle can use shouldn't be a problem. We need: An antenna Preamp/filter Mixer LO generator Filter on the output of the mixer to the radio. Cant' forget a signal source to test this stuff. Most of this can be had on epay. Some like the horn antenna can be made for practically nothing. Please offer comment here!! Found lots of good info and some software at w1ghz On the high end, this includes the block down converter option. Looking around, it's a crap shoot on this part.
Other is buy. Not so cheep.
The same approach I want to use can be applied to any other of these sats that work at microwave. Lets keep kicking the can down the road. Norm n3ykf BTW: I do have a 141t with the 8555a plugin conx unknown over 1gHz
