It's not the old product you were looking for, but the Rainbow Tuner does
what you are looking for, plus, it includes a built-in autoamtic
self-adjusting SWR bridge and indicator. It's on a small pc board, approx
2-14 x 3-1/4 and it will tune 30 or 40 meters with no component changes.
A manual that comes with the kit gives info on tuning to other bands.
The Rainbow was written up in the Decmeber '96 issue of QRPp and January
'97 QRP Quarterly.
It is available as a kit from NJQRP for $25.00 plus $3.00 shipping.
See the NJQRP web page at
For more info, including schematic diagram and specs or
send me an e-mail for a descriptive blurb.
