I have 100 NP0 caps for 1000pF and 150 pf. ?these are surface mount.? I would be happy to send some to anybody to try.? Just send a SASE to me (I am good on QRZ.com).? Note that I had a bit of difficulty with my mod, so your milage may vary. ?

all true, but i store my toroids in air. when the radio is cookin', i'd bet that a toroid parked in the middle of the top ( i.e. the side with the warm resistors attached and the side where they would radiate from) of that board is warmer than one parked on the bottom side. sounds like a test worthy hypothesis... and, true or not, would that be a factor in VFO stability??

and while i have ordered npo caps, and have considered changing and moving the inductor, currently my indian made bitx and i are at opposite ends of a continent... so, sadly, i can only conjecture at this point. but it would be fun to actually measure and see if it makes any significant difference. i.e. does it really help to move the toroid to the bottom of the board?
