just back from home. thank you very much for your posts. they make our board hot in such cold days.

not so hot as those days when you were in hefei. anyway, i'm trying. does your vxo work ok when 100p is used for c301 and c302? when i got back in shiyan, i constructed my vxo with the new pcb. it worked ok for a few days. with the main tune 30p,the coverage of 16000-16090 and 12390-12435 was achieved, but later the performance was no good. so i use 27p instead, the main tune 200p. it's been working very well. the coverage is the same! hi, hi.something wrong with my 100p capacitors? i don't know. anyway, use 27p.

my vxo worked perfectly when using 100p for both c301 and c302. i don't think big frequency coverage is good. if no frequency display is provided, tuning would be difficult. your 100p is good. when will you go back to shanghai?

it simply worked poorly even when the coverage was narrow. strange. it had worked perfectly. maybe the cause of the quality of the 100p i used. i'm leaving for shanghai on 18 or 19, depending on the ticket.

ok, i have something to talk with you via email. please check your email.
