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.

Is there another forum, because obviously everyone here just buys everything
and
maybe have forgotten what this hobby is all about!
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.
I am young, enthusiastic, and have lots of time, any help would be great. :)

Hi Enzo,
Either TNC should work, but I would give the advantage to the Paccomm for
AO-51.

That brings back a memory when I first started.
I didn't have all mode VHF equipment, just a two meter FM rig and
a kenwood TS-440. I wanted to listen to some of the SSB activity on two
meters, so I took the cover off the two meter rig, and tapped the IF from
the FM rig to the TS-440, and I could receive 2m SSB. Even though the FM
rig only did 5 khz steps, the IF output was still wide enough to cover
everything in the vicinity of the 2m frequency.
The things we do to have fun sometimes.
