However, the circuit diagram shows it as 0.1uF. As this coupling cap is in a 50 ohm part of the circuit and the RA1792 is specified down to 150kHz (Yes, we all know it goes a lot lower !), 0.1uF gives a break point at 32kHz so I guess 0.1uF is the correct value and the parts list is wrong. C4, doing a similar function before the amp, is 0.1uF Andy G4JNT > -----Original Message----- > From: tracey.gardner [mailto:tracey.gardner@ntlworld.com] > Sent: 2001-03-12 13:56 > To: rsgb_lf_group@blacksheep.org > Subject: LF: Re: RE: Manual > > > Hi Andy > > My 1792 manual shows C11 on the RF amp board to be 1uF 100v > whereas Brian's manual shows it to be 50v. > > 73s Tracey > > > > > I have access to a RA1792 manual, is there any particualr > area / info > >you need ? > >Farnell do a radial 1uF ceramic capacitor - part no. 287-064. > > > > Andy G4JNT > > > > > -- The Information contained in this E-Mail and any subsequent correspondence is private and is intended solely for the intended recipient(s).
