Hi Kevin, you wrote: >I know there is a kit out there for a receiver and or a SSB converter. >2-meter/70cm SSB receiver. I heard there was an article in QST so it >must exist. You might be thinking of the KK7B receivers which were in QST magazine in the early 1990s. These receivers included the R1 and R2 phasing receivers. According to the articles, these will work up to 500 MHz with the appropriate local oscillator and phase shift networks. The R1 is described in the August 92 QST "High Performance Direct Conversion Receiver" which you can read at http://www.arrl.org/files/file/Technology/tis/info/pdf/9208019.pdf The R2 is described in the January 93 QST article "High Performance Single Signal Direct Conversion Receivers" which you can read at http://www.arrl.org/files/file/Technology/pdf/t9301032.pdf You will also want to read the May 1993 QST which contains his article "Single-Conversion Microwave SSB/CW Transceivers". This article includes the schematic for a very simple 144 MHz local oscillator comprised of a basically a crystal, a 74HC04, a MAV11 and some filtering components. This article also contains the interconnect diagram for connecting the local oscillator, receiver and transmitter if you want to make a complete transceiver. (If you go this route, double check that the TOKO part numbers are still the same.) And, there's also "A Multimode Phasing Exciter for 1 to 500 MHz" in the April 1993 QST. Some of these articles also appeared in the ARRL publication "QRP Power" First edition chapters 3 and 4. Kits or at least circuit boards are available from Kanga US for SOME of the above circuits. You can examine Kanga's current offerings at http://www.kangaus.com/receivers.htm There's also the miniR2 and the R2pro (although I'm not sure if these go up to 70cm or not). The R2pro paper is at http://www.kangaus.com/R2Pro%20files/Original%20paper%20with%20figures.pdf You might also consider building (or buying) a 2m or 70cm down-converter and using that with a 10-meter receiver. I hope these references are helpful. Good luck! See you on the birds, Douglas KA2UPW/5 Disclaimers: These really are not beginner level kits. If you've never soldered a kit together, then you'll want to get some assistance for these. I have no relationship with Kanga. -Original Message- From: Kevin Deane To: amsat-bb@amsat.org Sent: Fri, Mar 4, 2011 9:50 pm Subject: [amsat-bb] KIT Is there another forum, because obviously everyone here just buys everything and maybe have forgotten what this hobby is all about!

[amsat-bb] Re: KIT
Kevin, I agree with Jeff. The last time there were dedicated VHF radios was when Heath still made them. But today you can find very nice HF radio kits and 2m and 70cm transceiver kits, which together make a fine multi-mode VHF/UHF radio. I would recommend the K2 HF radio kit from Elecraft http://www.elecraft.com/ and either their transceiver kits or kits from Downeast Microwave: http://www.downeastmicrowave.com/ I have the Elecraft K3 but it is not a traditional kit that is assembled by soldering pc boards (but only a mechanical kit). 73, Ed Perhaps there have been articles in QEX for building a complete radio for VHF. QST does not normally offer complicated projects. If you look thru my website you will see that I build a lot of my station, but not the central radio.

[amsat-bb] Re: KIT
Insulting people probably won't get you what you're looking for. I did a search of the QST archive and came up empty, so I doubt if there was an article (I could be mistaken). Most kits out there are for HF equipment usually QRP (low power), I don't personally know of a 2m/70cm kit of any kind. There are lots of homebrew projects but again they are mostly for HF. If you have more specific information, by all means post it here. I'd be interested. As for other forums, they are too numerous to list. Your best bet would be to go to Yahoo groups and do a search on applicable topics and/or equipment models. There are a lot of hams that still build stuff - mostly antennas, but other equipment as well. There just aren't very many kits out there anymore. If you run across a vhf/uhf kit of any kind, I'd be interested in learning more about it.
