The two output pins of the NJM2113 audio amp chip (U1) are each biased at about 6 volts DC. That's why they can't be allowed to be grounded - it shorts out the bias voltage and zaps the output

You are definitely not alone on no crystal osc. I found after many hours of work, that the bias of the oscillator of is very important. It needs to be at least 3.00 volts. Check my report in the

Darn. no 'c'. Well still like the way you guys think! The manual said at least 1 uf. would 10 be better? Also it says if using electrolytic with polarity, Positive side to the tip and or ring of

JP2 and JP3 are only on the rev A(c) boards. You can find that "revA(c)" designation on the silk screened legend just above the L5 and L6 on the top side of the main board. The earlier green panel

Where are JP 2 and 3? I only see JP1 on the manual. I know mine is a rev A but I am not sure if it is an A(c). Bob

I am sure some of us like me just assumed we blew it and replaced it on our own. They are not expensive and in my case I could get them much faster locally. Cheers Jeff Vk3GMO

I'm trying guys... can't get my antenna up due to physical issues. Have 40 EF wire... what is the best height for an inverted V ?

It has been brought up in the group in the last week or so.

Send an email to the person that kitted the BJ. They will send you a replacement. Email address is on the website.

Hi Dave -no it's not your brain... and I did it my way... not like Franky but take a look at the fotos I add... I also think we are not alone with this expereance of none oscillating Q4 and we wonder

Guys, This is just another instance of the wrong part (either in the kit or from your junque box). I know it takes longer but with the low cost of those Chinese part testers I am now testing each

" #16937 .. I'm pretty sure that IRF-510 transistors that are marked ""Y64K AP" work reasonably well at Q4, but those marked "618 P 77 WS" would kill the oscillator." So my IRF-510 is(!) marked "618

That'll be the 22 pF cap for use at C31 if needed. The "220" means 22 x (10 to the power zero) = 22 x 1 = 22 pF Much to small a capacitance to use for the DC block at the audio output. That will have

Yes the back side was 220 A1K. Can these be used for the DC blocking? Bob KG5GTE

The cap marked "10" is most likely the 10 pF cap included in the Bayou Jumper kit in case you needed to use it at C20a to lower the receive tuning range. There would have also been a 22 pF cap to be
