Heathkit IG-102 Signal Generator solid state conversion

I finally did the Heathkit IG-102 solid state conversion.  First a no-touch type of conversion was tried with LND-150 depletion mode high voltage MOSFETs - this "worked" but only up to 17 MHz or so.

So this morning I subbed 2n3819 JFETs for the LND150s.  Also the power cord was removed and the high-voltage parts were disconnected.

Per this article in a collection from 73 Magazine (see page 214):

I soldered in a 75 ohm resistor in parallel with a 33,000 ohm resistor and a 91 ohm resistor in parallel with a 4700 ohm resistor and tried it out.  It does oscillate, here is the waveform on 10 meters:


But the modulation LC oscillator doesn't seem to work, also the waveform is quite distorted (as it was before with tubes or the LND150) so that will have to be fixed - but later - I will quit for now with a win !
