Always on the look out for interesting QRP projects, the QRPme website has lots of interesting and low cost projects. They also sell crystals for QRP frequencies and MePads and MeSquares, which are very useful. In all, a useful resource for keen QRP enthusiasts.
I have a tuna can to build for a Steve Still that ordered it from you. I am missing the L1, 22UH inductor and the R7, 6.8 ohme resistor. Could I purchase these items?
Thanks

Hi,
I worked at Siliconix in the 70’s. I made a test fixture to measure bandwidth of
a CA3045 NPN array. The test fixture voltage was proportional to bandwidth, 300mV = 300 MHz.
I remember using a Boonton RF voltmeter to measure the output voltage.
I have been looking for the circuit, but can’t find anything on how to measure bipolar bandwidth.
It must have been an oscillator circuit with the output voltage proportional to bandwidth.
Do you know of this circuit or any method to measure bipolar and or FET bandwidth.
Thank you,
Wayne
